Mailchimp vs Constant Contact: Which Should You Pick?

Constant Contact is the better choice if your team needs live phone support, built-in event tools, and a fast path to your first send. Mailchimp wins when you need deeper automation, a larger template library, advanced A/B testing, and a free plan to start. The single biggest tradeoff is guided experience versus breadth: Constant Contact holds your hand through setup; Mailchimp gives you a more powerful toolkit and expects you to use it.

• Constant Contact fits nonprofits, local service businesses, and event-driven organizations that want US-based phone support and simple, ready-to-send templates.
• Mailchimp fits small e-commerce stores, growing businesses, and marketing teams that need multi-step automation, predictive segmentation, and a wide integration library.

Pro Tip: Before you pick based on price alone, check whether unsubscribed contacts count toward your billing limit. Mailchimp’s billing model counts unsubscribed contacts against your total unless you archive or delete them, which can push you into a higher tier faster than you expect.

How do Mailchimp and Constant Contact compare side by side?

Quick pros and cons:

Mailchimp pros:

• Permanent free plan for very small lists
• Deeper automation and multi-step journeys
• Advanced A/B testing across multiple variables
• Larger integration ecosystem

Mailchimp cons:

• Unsubscribed contacts count toward billing unless archived
• Steeper learning curve for beginners
• Phone support not available on standard plans

Constant Contact pros:

• US-based phone support on all paid plans
• Built-in event management (registration, RSVPs, ticketing)
• Faster onboarding for non-technical teams
• Simpler, guided experience

Constant Contact cons:

• No permanent free plan
• Basic automation compared to Mailchimp
• A/B testing limited to subject lines
• Less flexibility in template customization

Which platform is easier to use and build emails with?

The editor experience is where these two platforms feel most different day to day. Mailchimp gives you a drag-and-drop builder with granular control over columns, spacing, and content blocks, plus a classic text editor for plain-text campaigns. That flexibility is genuinely useful for a marketing team that wants pixel-level control, but it adds friction for someone sending their first newsletter.

Constant Contact uses a block-based drag-and-drop editor that constrains your choices in a helpful way. You pick a layout, drop in your content, and you are done. A volunteer coordinator at a local nonprofit can send a polished event invite in under 30 minutes without ever touching a style setting.

Setup time matters more than most buyers realize. G2’s user-sourced comparison data consistently shows Constant Contact scoring higher on ease of setup and lower on learning curve, while Mailchimp scores higher on editor strength and feature depth. Those two scores tell the whole story.

Practical differences:

• Mailchimp’s editor supports conditional content blocks (show different content to different segments in the same email), which Constant Contact does not offer at the same depth.
• Constant Contact’s editor previews mobile and desktop simultaneously as you build, reducing back-and-forth.
• Mailchimp’s “Creative Assistant” uses AI to generate branded content suggestions based on your website, which can speed up design for new users once it is configured.

Pro Tip: If your team includes volunteers or part-time staff who will be sending campaigns, test the editor with the least technical person on your team before you commit. A platform that requires a 20-minute tutorial every time someone logs in will slow your entire operation.

How do templates and deliverability testing compare?

Constant Contact ships with over 200 ready-to-send templates organized by industry and campaign type. They are polished, mobile-responsive, and designed to be sent with minimal editing. The tradeoff is that customization has limits: you can swap colors and images, but restructuring the layout requires more effort than it does in Mailchimp.

Mailchimp’s template library includes more than 100 templates and is more flexible. You can start from a pre-built template, build from scratch with the drag-and-drop editor, or code your own HTML. For a brand with strict design guidelines, that flexibility matters. Forbes Advisor’s comparison highlights this exact tradeoff: Constant Contact wins on template volume and speed-to-send; Mailchimp wins on design control and customization depth.

On deliverability, both platforms maintain strong inbox placement rates. Mailchimp offers send-time optimization (it analyzes your audience’s past open behavior and schedules sends at the predicted best time), which Constant Contact does not match at the same depth. Mailchimp also includes a built-in inbox preview tool that shows how your email renders across major clients like Gmail, Outlook, and Apple Mail before you send.

Pro Tip: Pick a template with a single-column layout for your first few campaigns. Multi-column layouts break more often across email clients, especially on mobile. Once you have a working template, save it as a custom template so your team reuses the same structure every time.

What automation and A/B testing can each platform handle?

This is where the gap between the two platforms is most pronounced. Mailchimp supports multi-step automation journeys with behavioral triggers, e-commerce events (abandoned cart, product follow-up, purchase anniversary), and conditional logic that routes contacts down different paths based on their actions. Constant Contact covers the basics: welcome series, birthday emails, and simple drip sequences. That is enough for many small organizations, but it hits a ceiling quickly for anyone running complex campaigns.

Automation types available:

• Mailchimp: Welcome series, abandoned cart, post-purchase follow-up, re-engagement, date-based triggers, behavioral triggers, multi-step journeys with branching logic
• Constant Contact: Welcome series, birthday/anniversary emails, basic drip sequences, resend to non-openers

Segmentation follows the same pattern. Mailchimp lets you build segments using tags, list membership, purchase history, predicted demographics (age, gender, location likelihood), and engagement scores. Constant Contact uses lists and tags with simpler filtering logic. For a donor engagement workflow or a tiered customer nurture sequence, Mailchimp’s segmentation depth is genuinely useful.

A/B testing is a clear Mailchimp advantage. You can test subject lines, sender names, content variations, and send times simultaneously, with Mailchimp automatically sending the winning version to the remainder of your list. Constant Contact limits A/B testing to subject lines only.

Three use-case workflows where the difference shows:

1. Donor onboarding for a nonprofit: Mailchimp can trigger a 5-step welcome series based on donation amount, tag the donor by campaign source, and send a different follow-up to first-time vs. recurring donors. Constant Contact can send a welcome email and a follow-up, but the branching logic is not there. For deeper nonprofit donor engagement strategies, the automation depth matters.
2. Abandoned cart for e-commerce: Mailchimp connects directly to Shopify or WooCommerce and fires a cart recovery email within an hour of abandonment. Constant Contact requires a third-party integration to replicate this.
3. Event follow-up sequence: Constant Contact’s built-in event tools let you send a registration confirmation, a reminder, and a post-event thank-you without leaving the platform. Mailchimp requires Eventbrite or a similar integration to handle registration, then automates the follow-up.

Pro Tip: If your automation needs are limited to a welcome series and occasional re-engagement campaigns, Constant Contact’s simpler tools are faster to configure and maintain. Save the multi-step journey builder for when you have the audience data to make branching logic worth the setup time.

How does list management work, and what are the billing traps?

List structure is a practical operational question, not just a features question, because it directly affects what you pay.

Mailchimp organizes contacts into Audiences (their term for lists). Each Audience is separate, meaning a contact who appears in two Audiences counts twice toward your billing total. Within an Audience, you use tags and segments to organize contacts. The billing trap: unsubscribed contacts count toward your contact limit unless you archive or delete them. A list that has been running for two years can accumulate hundreds of unsubscribed contacts that silently inflate your bill. This is confirmed by multiple third-party sources as one of the most common billing surprises on the platform.

Constant Contact uses lists with a simpler structure. Contacts can belong to multiple lists without being counted multiple times, which is a meaningful operational advantage for organizations managing overlapping audiences (donors who are also volunteers, customers who are also newsletter subscribers). Unsubscribed contacts do not count toward billing in the same way, reducing the hygiene burden.

Event management is a Constant Contact strength with no real Mailchimp equivalent built in. You can create event registration pages, sell tickets, manage RSVPs, and send automated reminders, all inside the platform. For a nonprofit running a fundraising gala or a local business hosting a workshop, that eliminates the need for a separate Eventbrite account.

Pro Tip: In Mailchimp, run an audience cleanup every 90 days. Archive contacts who have been unsubscribed for more than 6 months and remove hard bounces immediately after each send. This single habit can keep you in a lower pricing tier.

What do reporting and deliverability monitoring look like?

Mailchimp’s reporting is the more powerful of the two. Standard reports cover open rate, click rate, bounces, unsubscribes, and abuse reports. On paid plans, you also get revenue attribution (which campaigns drove purchases), comparative campaign reports (how this send performed against your last five), and click maps showing exactly where subscribers clicked inside the email. Send-time optimization is available on higher-tier plans and uses historical engagement data to predict the best delivery window for each contact.

Constant Contact’s reporting covers the core metrics: opens, clicks, bounces, and unsubscribes. You can see which contacts opened and clicked, which is useful for manual follow-up. What is missing is the cross-campaign comparison view and revenue attribution that Mailchimp provides on paid plans. For a small business sending a monthly newsletter, that is not a gap that matters. For a marketing team running multiple concurrent campaigns and trying to optimize over time, it is.

TechnologyAdvice’s buyer guidance makes the point directly: as small businesses scale, deeper reporting and automation become more valuable despite the steeper learning curve, because they enable data-driven decisions that simpler tools cannot support.

Metrics a marketing team should check after every campaign:

• Open rate (benchmark varies by industry; compare against your own previous sends first)
• Click-to-open rate (clicks divided by opens, not total sends; a better measure of content relevance)
• Bounce rate, split between hard and soft bounces
• Unsubscribe rate per campaign (a spike signals a relevance or frequency problem)
• Revenue per email sent (Mailchimp paid plans; requires e-commerce integration)

Which platform has better integrations and extra channels?

Both platforms connect to 300+ third-party apps, but the integration quality and depth differ by category.

Mailchimp’s integration ecosystem is broader and deeper for e-commerce and CRM. Native connections to Shopify, WooCommerce, BigCommerce, and Magento pull purchase data directly into Mailchimp for segmentation and automation. Salesforce, HubSpot, and Pipedrive integrations sync contact data bidirectionally. Zapier connects Mailchimp to virtually any tool not covered natively. For a multi-channel campaign that combines email with social posting and paid ads, Mailchimp’s ad management tools (Facebook, Instagram, Google remarketing) are built in.

Constant Contact’s integrations are strong in a different set of categories. QuickBooks and Xero integrations make it a natural fit for service businesses that want to connect billing and marketing. Eventbrite integration extends the built-in event tools. Salesforce and Shopify connections exist but are less deep than Mailchimp’s native implementations.

SMS is available on both platforms, but as an add-on or higher-tier feature rather than a core offering on entry plans.

Pro Tip: Before you evaluate the full integration catalog, identify the three tools your team uses every day: your CRM, your e-commerce platform, and your scheduling or event tool. If both platforms connect to all three natively, the integration question is settled and you can focus on features and price.

How does support compare between the two platforms?

Constant Contact’s US-based phone support is available Monday through Saturday on all paid plans. That is a genuine differentiator. Most email platforms at this price point offer chat and email only. For a nonprofit with a volunteer-run marketing function, or a small business owner who does not want to troubleshoot a broken campaign via a ticket queue, the ability to call someone and get help in real time is worth a meaningful premium.

Mailchimp offers live chat Monday through Friday and email support. Phone support is not available on standard plans. The knowledge base is extensive and well-organized, and the community forum is active, but self-service is the primary support model.

Support comparison:

• Constant Contact: Phone (Mon–Sat), live chat, email, knowledge base, active onboarding help for new accounts
• Mailchimp: Live chat (Mon–Fri), email, knowledge base, community forum; no phone support on standard plans

Onboarding is another Constant Contact strength. New accounts get active setup guidance, including help importing contacts and sending the first campaign. Mailchimp’s onboarding is self-directed: a checklist, tutorial videos, and a well-documented help center, but no one walks you through it.

G2’s aggregated user data shows Constant Contact consistently scoring higher on quality of support, while Mailchimp scores higher on feature depth and integration breadth. Those scores reflect the same tradeoff visible everywhere else in this comparison.

What does pricing actually look like at different list sizes?

Both platforms bill per contact, but the details matter. SMBCompare’s 2026 analysis confirms that both platforms price in US dollars on a per-contact basis, and which one is cheaper depends on your list size and the features you need.

Mailchimp plan structure:

• Free: Up to 500 contacts, 1,000 sends/month, basic templates, no automation
• Essentials: Starts around $13/month (500 contacts); adds A/B testing, custom branding, 24/7 chat support
• Standard: Starts around $20/month (500 contacts); adds send-time optimization, behavioral targeting, multi-step journeys
• Premium: Starts around $350/month (10,000 contacts); adds advanced segmentation, multivariate testing, phone support

Constant Contact plan structure:

• No free plan; 30-day free trial
• Lite: Starts around $12/month (500 contacts); core email tools, basic reporting
• Standard: Starts around $35/month (500 contacts); adds automation, segmentation, A/B testing
• Premium: Starts around $80/month (500 contacts); adds advanced automation, custom reporting

Estimated monthly costs by list size:

Prices are approximate based on published plan structures and vary with promotional pricing. Verify current rates on each vendor’s pricing page before purchasing.

Scenario examples:

• Starter nonprofit (1,000 contacts, event-driven): Constant Contact Lite at ~$12/month covers email plus built-in event tools. Mailchimp Free works if you stay under 500 contacts and can live without automation.
• Local service business (2,500 contacts, monthly newsletter): Either platform’s entry plan covers this. Constant Contact wins on support; Mailchimp wins if you want the free plan as a fallback.
• Small e-commerce store (5,000 contacts, abandoned cart automation): Mailchimp Standard at ~$100/month gives you native Shopify integration and behavioral triggers. Constant Contact Standard at ~$110/month works but requires more integration setup for e-commerce automation.

Pro Tip: Calculate your real billable contact count before signing up. In Mailchimp, export your list and count only subscribed contacts. Then add 15–20% to account for new subscribers over the next year. That number, not your current total, is what you should use to estimate monthly cost.

How do you decide which platform fits your business?

Work through this in order. The answer usually becomes clear by step three.

1. Do you need live phone support? If yes, Constant Contact is the only option at this price point with US-based phone support on standard plans. Skip to step 5.
2. Do you run in-person or virtual events? If event registration, ticketing, and RSVPs are core to your operation (fundraising galas, workshops, community events), Constant Contact’s built-in event tools save you a separate tool subscription.
3. Do you need multi-step automation or e-commerce triggers? Abandoned cart, post-purchase sequences, behavioral branching, and predictive segmentation all require Mailchimp Standard or higher. If your automation needs stop at a welcome series, either platform works.
4. What integrations are non-negotiable? Map your current tech stack. If you run Shopify and need native purchase data in your email platform, Mailchimp’s native integration is deeper. If you use QuickBooks and Eventbrite, Constant Contact’s native connections are stronger.
5. What is your realistic monthly budget? At small list sizes (under 1,000 contacts), the price difference is minimal. At 5,000+ contacts, run the numbers for the specific plan tier you actually need, not the entry plan.

Buyer personas:

• Nonprofit fundraiser: Constant Contact for phone support, event tools, and simple donor welcome sequences. Upgrade to Mailchimp if you need donor segmentation by giving history and multi-step journeys.
• Local service business: Either platform works. Constant Contact if you want guided support; Mailchimp if you want the free plan and plan to grow into automation.
• Small online store: Mailchimp Standard for native e-commerce integration, abandoned cart automation, and revenue attribution reporting.

Pro Tip: Migration between platforms is procedural but not trivial. Exporting a CSV and importing it takes an afternoon. Rebuilding your automation workflows, custom templates, and segmentation logic takes days. If you have more than 10,000 contacts or complex automations, budget for outside help rather than assuming the switch is a weekend project.

What are the final recommendations and next steps?

Mailchimp is the better platform for most growing businesses that need automation depth, e-commerce integration, and a free starting point. Constant Contact is the better platform for nonprofits, local service businesses, and any team that values live phone support and built-in event management over feature breadth.

Practical next steps:

• Try before you commit: Mailchimp’s free plan (up to 500 contacts) lets you test the editor, templates, and basic automation with no credit card. Constant Contact’s 30-day free trial covers the full feature set. Run both trials with a real campaign if you have the time.
• Export and audit your list first: Before migrating, export your current contact list, remove hard bounces and long-term unsubscribes, and map your custom fields to the new platform’s field names. Clean data imports cleanly.
• Get help if the migration is complex: If you have active automation workflows, custom integrations, or a donor database with years of engagement history, a consulting engagement will save you more time than it costs.

If you are a nonprofit evaluating these platforms alongside your broader fundraising and marketing setup, a nonprofit marketing plan template can help you map email into your full strategy before you pick a tool.

How do you switch between Mailchimp and Constant Contact?

The migration path between these two platforms is well-documented and procedural. Mailchimp’s official migration guide walks through the process of exporting your contact list from Constant Contact as a CSV and importing it into a Mailchimp Audience. The same process works in reverse: export from Mailchimp, import to Constant Contact.

The steps that trip people up are not the export and import. They are the field mapping, the tag and segment recreation, and the automation rebuild.

What the migration actually involves:

• Export contacts as a CSV from your current platform (include all custom fields, tags, and subscription status)
• Clean the file: remove hard bounces, unsubscribes, and duplicate entries before importing
• Map custom fields to the new platform’s field names (first name, last name, and email are standard; anything custom needs manual mapping)
• Recreate segments and tags in the new platform (these do not transfer automatically)
• Rebuild automation workflows from scratch (no migration tool moves live automations between platforms)
• Update any embedded signup forms on your website to point to the new platform
• Redirect any Zapier or third-party integrations to the new account

For a list under 5,000 contacts with no active automations, a careful person can complete the migration in a day. For a nonprofit with donor segments, event lists, multi-step welcome sequences, and a Salesforce integration, budget a week and consider professional help.

What do customers say about each platform?

User reviews across G2, Capterra, and similar platforms tell a consistent story that matches the feature comparison above.

Mailchimp user feedback patterns:

• Praised for template variety, automation power, and the free plan’s generosity for small lists
• Criticized for the billing model (unsubscribed contacts counting toward limits), pricing increases as lists grow, and the learning curve for advanced features
• Support response time on chat is generally rated as adequate but not exceptional

Constant Contact user feedback patterns:

• Praised for ease of use, phone support quality, and the event management tools
• Criticized for the lack of a free plan, limited A/B testing, and basic automation compared to alternatives
• Onboarding experience is consistently rated as a strength, particularly for first-time email marketers

G2’s comparative scoring shows both platforms performing similarly on overall satisfaction, with Constant Contact edging ahead on support and ease of use, and Mailchimp leading on feature depth and integration breadth. That pattern holds across multiple review aggregators.

One practical note: negative Mailchimp reviews spike around billing surprises, specifically the unsubscribed contact billing behavior flagged earlier. This is not a hidden policy, but it catches users who do not read the pricing documentation carefully. EmailOctopus’s roundup of Mailchimp alternatives cites this as one of the most common reasons users switch platforms.

Key Takeaways

Mailchimp wins on automation, integrations, and a free starting plan; Constant Contact wins on live phone support, built-in event tools, and ease of use for non-technical teams.

When does hiring Hyphenateconsulting actually make sense?

Most buyers can self-serve a platform migration if their list is clean and their automation is simple. The cases where outside help pays for itself are specific, and worth naming directly.

The first is a nonprofit with years of donor data in one platform and a need to migrate without losing engagement history, segment logic, or the tagging structure that drives their fundraising sequences. A field-mapping error on a 10,000-contact donor list is not a recoverable afternoon problem. The second is any organization connecting their email platform to a CRM like Salesforce or a donor management system, where bidirectional sync requires configuration that goes well beyond a CSV import. The third is a team that has been running on the wrong platform for years and has accumulated broken automations, duplicate contacts, and inconsistent tagging that needs to be cleaned before any migration makes sense.

These are the situations where Hyphenateconsulting’s work with nonprofits, churches, and small businesses in Minneapolis delivers the most direct value. The agency’s background in marketing consulting means the platform selection conversation does not happen in isolation; it happens alongside the broader question of how email fits into your donor engagement strategy, your grant outreach, and your website conversion flow.

Pro Tip: The most common migration pitfall is importing a dirty list into a new platform and assuming the new tool will fix the underlying data problems. It will not. Clean your list before you migrate, not after.

Hyphenateconsulting: expert help for platform selection and migration

Choosing between Mailchimp and Constant Contact is straightforward when your needs are clear. When they are not, or when the migration involves donor data, CRM integrations, or years of accumulated contact history, the cost of getting it wrong is higher than the cost of getting it right the first time.

Hyphenateconsulting works with nonprofits, churches, and small businesses to select the right email platform, migrate contacts cleanly, and set up the automation and segmentation that actually matches how the organization operates. Every engagement includes educational resources so your team can manage the platform independently after the work is done. Both Mailchimp and Constant Contact are valid self-serve choices for organizations with simple needs.
