Constant Contact vs Mailchimp (2026): Which Is Better?

Constant Contact and Mailchimp are two of the oldest names in small-business email. Constant Contact launched in the late 1990s, Mailchimp in 2001. If you have run a newsletter or a small marketing list in the last twenty years, you have probably bumped into both. They have aged differently. Mailchimp turned into a broader marketing platform after its Intuit acquisition. Constant Contact stayed closer to its roots as a friendly tool for small businesses, nonprofits, and event organizers.

So which one should you actually pay for in 2026? I went through both pricing pages, the plan tiers, the automation features, and the support options. The short answer is that the right pick depends on your list size and how much automation you need. The longer answer is below, and there is a real case where neither one is the tool you want.

One thing worth saying up front: these are not interchangeable. They started in roughly the same place, simple email blasts for small businesses, and grew in different directions. Mailchimp chased the marketing-platform crowd. It added landing pages, ads, ecommerce, a CRM-lite, and a lot of automation, and its pricing reflects that ambition. Constant Contact stayed focused and stayed friendly. It kept the phone line open, leaned into events and nonprofits, and resisted the urge to become a do-everything suite. Which of those two philosophies fits you matters more than any single feature comparison.

Quick comparison

Here is the head-to-head at a glance. Prices are for the entry tier of each plan and scale up with your contact count.

Pricing is current as of 2026 and changes often; confirm on each provider's site.

Pricing, side by side

Both tools charge based on the number of contacts in your list, and both raise the price as your list grows. The starting numbers look close. They diverge fast once you scale.

Constant Contact pricing

Constant Contact has three plans, all priced here at the 500-contact tier:

• Lite: $12/month. Email, hundreds of templates, basic automation, contact management.
• Standard: $35/month. Adds more automation templates, an AI campaign builder, automatic resend to non-openers, scheduling, and deeper reporting.
• Premium: $80/month. Adds custom automation, advanced segmentation, ecommerce features, and priority support.

There is no free plan. You get a 30-day trial capped at 100 total email sends, and prices rise as your contact count goes up. You can save up to 15% by prepaying for a year. Constant Contact also runs frequent first-month promotions, so the headline price you see may be a discounted intro rate.

Mailchimp pricing

Mailchimp has a free plan and three paid tiers, priced here at roughly the 500-contact tier:

• Free: $0. Up to 250 contacts and 500 sends a month, single audience, limited templates, email support for the first 30 days only.
• Essentials: from $13/month. Removes Mailchimp branding, adds more templates and basic automation, 24/7 email and chat support.
• Standard: from $20/month. This is where Mailchimp gets good. Multi-step customer journeys, behavioral targeting, send-time optimization, and predictive tools.
• Premium: from $350/month. Advanced segmentation, unlimited seats, phone support, and dedicated onboarding.

The free plan is the headline. It is genuinely useful for someone just starting out. What hurts is that Mailchimp's per-contact pricing rises steeply, and many people find that Standard at a real list size costs more than they expected. Note that Mailchimp counts subscribed, unsubscribed, and non-subscribed contacts toward your billed total unless you archive them, which inflates the number you pay for.

So at the very bottom, Mailchimp is cheaper because it is free. In the middle, Constant Contact Standard ($35) sits above Mailchimp Standard ($20) on paper, but the feature sets are not equal, which I will get into. At the high end, Constant Contact Premium at $80 starts far below Mailchimp Premium at $350, though again the plans are aimed at different buyers.

How the price scales

The starting price is not the number that matters. Both tools charge by contact count, and the curve is what bites you six months in.

Mailchimp's curve is steeper. The free and Essentials tiers feel cheap at 500 contacts, but a list of 10,000 on Standard runs into the low hundreds per month, and Premium starts at $350 before custom pricing at very high contact counts. The thing people miss is how Mailchimp counts your audience. Contacts who unsubscribed or never subscribed still count toward your billed total unless you archive them, so the figure on your invoice is usually higher than the number of people you actually email. If you do not clean your audience regularly, you pay for dead weight.

Constant Contact also rises with list size, but the headline comparison depends on which tiers you compare. Premium starts at $80 for the base tier versus Mailchimp Premium at $350, while Standard-vs-Standard pricing is not always cheaper for Constant Contact. There is no hidden penalty for unsubscribed contacts in the same way. For a large but simple list, where you just send a monthly newsletter to twenty thousand people, Constant Contact can still end up the cheaper of the two, but check the exact tier rather than assuming the curve.

If raw cost across list sizes is your main worry, our roundup of the best email marketing for small business compares a wider set of tools on price.

Automation

This is where the two tools separate the most.

Constant Contact keeps automation simple. You get welcome emails, birthday and anniversary sends, automatic resend to people who did not open, and a set of templated automation paths. On Standard you also get an AI campaign builder that drafts a sequence for you. It covers what most small businesses and nonprofits actually run, which is a welcome series and the occasional triggered email. It does not give you deep branching logic.

Mailchimp goes much further on its Standard plan. Customer Journeys let you build multi-step flows with branching based on behavior, purchases, tags, and conditions. You can split paths, wait for events, and react to what someone does inside an email. If your marketing depends on "if they clicked this, send that, otherwise wait three days and try again," Mailchimp Standard is built for it and Constant Contact is not.

For a refresher on what these flows are meant to do, our guide to drip campaigns walks through the common sequences. If you are weighing Mailchimp against other automation-heavy tools, Mailchimp vs Brevo covers that matchup directly.

Templates and editor

Both ship hundreds of email templates and a drag-and-drop editor, and honestly the gap here is small. Mailchimp's editor feels a little more modern and its template library is large and well organized. Constant Contact's editor is easy to learn and its templates lean toward small business and event use, with strong event and registration blocks that Mailchimp does not match.

If you send a lot of event invitations, registrations, and RSVPs, Constant Contact has a real edge because event marketing is part of the product, not a bolt-on. For general newsletters and campaign emails, either editor will get you a clean result without touching HTML.

Both also include AI writing help now. Mailchimp's content tools draft subject lines and body copy and suggest send times. Constant Contact's AI campaign builder goes a step further by drafting a whole sequence. I would not lean on either to write your emails for you, but for a first draft or a stuck subject line they are useful enough.

Segmentation and list management

Segmentation is how you stop blasting the same email to everyone. Mailchimp is stronger here. You can build segments on behavior, purchase history, engagement, location, and custom fields, and combine those conditions with and/or logic. Predictive segments on the higher tiers try to guess who is likely to buy or churn. For anyone running targeted campaigns, this depth pays off.

Constant Contact gives you tagging, basic list segmentation, and engagement-based groups like recent openers and clickers. It covers the common cases, splitting your list by interest or activity, but it does not match Mailchimp's conditional depth. If your campaigns are simple and your list is one audience, you will not feel the gap. If you slice your list a dozen different ways, Mailchimp handles it better.

Reporting and analytics

Both give you the standard metrics: opens, clicks, bounces, unsubscribes, and click maps. Mailchimp's reporting is more detailed, with revenue attribution, comparative reports against industry benchmarks, and ecommerce tracking that ties sends to orders when you connect a store. If you sell online and want to know which email drove which sale, Mailchimp shows it more clearly.

Constant Contact's reports are cleaner and easier to read at a glance, which fits its audience. You get the numbers that matter for a newsletter or a campaign without a dashboard full of charts you will never use. Neither is weak here. Mailchimp simply gives you more, which is either a feature or a distraction depending on how you work.

Support

Support is one of Constant Contact's clearest advantages. Phone and live chat are available across its plans, which matters a lot if you are a small business owner who would rather call someone than dig through a help center.

Mailchimp gates support by plan. The free plan gives email support for the first 30 days, then drops to self-serve. Essentials and Standard get 24/7 email and chat. Phone support is reserved for the Premium plan. So if talking to a human quickly is important to you and you are not on Mailchimp's top tier, Constant Contact is the safer bet.

Deliverability

Both are long-established senders with reputable infrastructure, and in normal use both land in the inbox. Neither publishes a guaranteed delivery rate, and you should be skeptical of any tool that does. Your own list hygiene, authentication setup, and sending habits determine deliverability far more than the brand name on the dashboard.

If you are setting up either tool, get your SPF, DKIM, and DMARC records right and warm up gradually. Our email deliverability guide covers the setup that actually keeps you out of spam folders.

Who should pick which

Here is the honest resolution.

Pick Constant Contact if you are a small business, nonprofit, or event organizer who wants something easy to use, with real phone and chat support, and you do not need complex automation. It can also be the cheaper choice at the higher end if you have a large list but simple needs, since Premium starts much lower than Mailchimp Premium at $350. Event marketing is a bonus that Mailchimp cannot match.

Pick Mailchimp if you want to start free, if you need deep automation and customer journeys, or if you run an online store and want ecommerce features and integrations. Its Standard plan is the better marketing engine for anyone whose campaigns depend on behavioral triggers and branching logic. Just watch the per-contact pricing as your list grows, and consider how it counts unsubscribed contacts.

A practical way to decide: list the three things you do most with email. If two of them are "send a newsletter" and "promote an event," Constant Contact wins on simplicity and support. If two of them are "trigger a flow when someone does X" and "track which email drove a sale," Mailchimp wins on capability. Pricing should be the tiebreaker, not the starting point, because the cheapest tool you outgrow in three months is not actually cheap.

For a deeper look at each on its own, see our Constant Contact review and our Mailchimp review. If you have decided Mailchimp is not for you, the best Mailchimp alternatives covers what SaaS teams move to instead.

A third option if neither fits

Both of these tools assume you are running marketing campaigns to a list you uploaded. That is the wrong shape for a lot of software teams.

If you are building a SaaS product or a web app, most of your email is not a newsletter. It is the welcome email after signup, the password reset, the receipt, the "you left something in your cart," the re-engagement nudge after a user goes quiet. That email is triggered by what happens in your database, not by a campaign you schedule. Constant Contact and Mailchimp's core marketing products are not built for that. Mailchimp can handle transactional sending through a paid add-on, but the main workflow is still list and campaign based rather than database-native.

Dreamlit is built for exactly this case. It connects directly to your Supabase or Postgres database and builds email workflows from your schema. You describe what you want in plain English, and it handles the trigger logic, the templates, the copy, and the timing. It runs as an MCP server, so it works from tools like Claude, Cursor, Lovable, and Bolt, rather than through a REST API or SMTP relay. Email workflows are the core use case, it is Supabase and Postgres only, and it is not a replacement for SMS or landing-page tooling. If your email should fire off your own data instead of a marketing calendar, that is the fit.

For teams already on Supabase, our guide to sending emails from Supabase shows the difference in practice. You can check current Dreamlit pricing on the pricing page.

The verdict

For most small businesses choosing between just these two, the decision comes down to two questions. Do you need deep automation or an online store? Go Mailchimp, and start on the free plan to test it before you commit. Do you want simplicity, strong human support, and a lower ceiling on price? Go Constant Contact, and skip the trial straight to Lite or Standard.

If you are genuinely torn, the free trial costs you nothing on either side. Build the same campaign in both over a weekend, send it to a test list, and notice which one you fight with less. The tool you reach for without dread is the one you will actually use, and an email tool you avoid is worse than no tool at all.

And if you are a developer or SaaS team reading a small-business email comparison because you needed somewhere to start, the real answer is probably neither. You want email driven by your database, which is a different tool entirely.

Frequently asked questions

Is Constant Contact or Mailchimp cheaper?

It depends on list size and plan tier. Mailchimp has a free plan (up to 250 contacts, 500 sends a month) and a cheaper entry tier, so it wins for tiny or zero-budget lists. Constant Contact has no free plan; its Lite plan starts at $12/month and its Premium tier starts far below Mailchimp Premium, but Standard-vs-Standard pricing is not always cheaper. Compare the exact contact tier you need on both pricing pages before deciding.

Does Constant Contact have a free plan?

No. Constant Contact offers a 30-day free trial capped at 100 total email sends, but there is no permanent free tier. If you want to send for $0/month, Mailchimp's free plan is the only one of the two that does it, capped at 250 contacts and 500 sends a month.

Which has better automation?

Mailchimp, once you reach its Standard plan. Standard unlocks multi-step customer journeys, behavioral triggers, and branching logic that go well beyond what Constant Contact offers at the same level. Constant Contact's automation is simpler: welcome series, resend to non-openers, and a handful of templated flows. For basic drip sequences either tool is fine. For complex branching journeys, Mailchimp Standard is the stronger pick.

Which is easier for a non-technical small business?

Constant Contact. Its interface is more straightforward, it leans on phone and live chat support across plans, and event marketing plus the simpler automation make it friendly for someone who does not want to learn a marketing platform. Mailchimp is more capable but has more surface area to learn.

How does deliverability compare?

Both are established senders with solid deliverability when you follow list hygiene and authentication basics. Neither publishes a guaranteed inbox rate, and real-world deliverability depends far more on your own sending practices, list quality, and SPF/DKIM/DMARC setup than on the brand. See our deliverability guide for the setup that actually keeps you out of spam.

Can I import my Constant Contact list into Mailchimp, or the reverse?

Yes. Both let you export contacts as a CSV and import into the other, and both have migration help. The harder part is rebuilding automations and templates, since those do not transfer. Plan for a few hours of re-work if you have active journeys running.

Which should I pick for an online store?

Mailchimp has deeper ecommerce features, product retargeting blocks, and integrations with most store platforms, so it suits sellers better at the Standard tier and above. Constant Contact has ecommerce features on Premium but they are not as deep. If you run a Shopify store, also look at purpose-built Shopify email apps.

Is there a better option for a SaaS app built on Supabase or Postgres?

Often, yes. Constant Contact and Mailchimp's core products are built for marketing lists, not for database-triggered product email from an app. Mailchimp can add paid Transactional Email, but neither core workflow is database-native. If you are a SaaS or developer team that wants email driven by your own database, a tool like Dreamlit connects to Supabase or Postgres and builds the flows from your schema. Sources:
