Constant Contact vs. Mailchimp: Which is best? [2025]

There’s enough to deal with on the human side of email marketing—from building out content to brainstorming subject lines that warrant a click—that you want to be sure your email marketing software is dealing with the rest.

I’ve used a bunch of email marketing tools in my time as a marketer, but for this article, I spent time testing Constant Contact and Mailchimp to see how they stack up. Here’s what I found.

Constant Contact vs. Mailchimp at a glance

Here’s the quick version:

• Constant Contact: Best for email marketing beginners who need simple features, ready-to-send templates, and phone support

• Mailchimp: Best for skilled email marketers looking for access to advanced reporting and A/B testing capabilities 

Mailchimp offers more affordable pricing—especially if you have smaller lists 

Constant Contact and Mailchimp offer fairly different pricing structures. For starters, Constant Contact doesn’t have a free plan (it offers a 30-day free trial, regardless of the number of subscribers or emails sent). Mailchimp, on the other hand, offers free email marketing software for up to 500 contacts and 1,000 sends per month.

After the free introduction, both Mailchimp and Constant Contact break pricing down by number of contacts. Here’s how they compare for their basic plans:

Each app also offers more advanced plans with extra features:

Here are the price breakdowns of each of these upgraded plans.

Constant Contact’s Standard and Premium plans land between Mailchimp Standard and Mailchimp Premium in terms of pricing.

Head spinning yet? Here’s the gist: overall, Mailchimp offers better pricing for users starting from scratch, but Constant Contact is slightly cheaper in some instances as you scale. Overall, pricing won’t be a differentiator until you know exactly which plan and features you need. 

Mailchimp offers a more intuitive and user-friendly way to customize emails

Mailchimp provides two options to build emails. If you prefer a simpler interface, you can use the classic builder to create templates and make edits in the sidebar. The new email builder makes designing even easier: you can drag and drop content blocks and edit everything in place, which I found to be much easier and faster than the original editor.

Another useful feature in the new builder is the addition of dynamic content blocks that let you control what different audiences see in the email. (Note: only users that pay for the Standard and Premium plans can access this feature.)

Meanwhile, the Constant Contact email builder is comparable to the new Mailchimp one, with a similar drag-and-drop design interface. To build your email, you’ll drag your desired text blocks, images, buttons, tables, and so on from the sidebar on the left. After dragging in your desired blocks, you can edit them directly within the email itself.

Ultimately, both provide all the nuts and bolts you’ll need to get your emails off the ground, but I found Mailchimp’s new builder to be the most intuitive option. 

Constant Contact’s wide variety of fully designed templates require little effort

If you’re ok with a slightly cookie-cutter feel, Constant Contact has hundreds of ready-to-send templates that are perfect for beginners or small businesses without in-house designers. As someone with little to no design ability, I can sleep soundly knowing there’s a themed template for just about any occasion I could think of, from National Dog Day and Friday the 13th to Small Business Week and Labor Day.

Mailchimp’s themes are also pretty, but they’re not as specific as Constant Contact’s when it comes to particular holidays and events (and there are about half as many of them). Plus, free plan users are restricted to the basic templates that lack preset stock images. (You’ll need to grab photos of those hot dogs and beach puppies yourself.)

Both platforms also give you the option to code your own template. 

Mailchimp offers more robust list management 

Audience segmentation is important for any email marketer, allowing for precise targeting and personalization. Both Mailchimp and Constant Contact let you organize your audience at a few levels: Lists, Segments, and Tags. These tools allow for some powerful testing and customization of your audience. 

The main difference is that Mailchimp also allows you to segment customers into Groups based on their interests and preferences. This segmentation usually occurs as customers are filling out a form. For example, if you’re a meal kit delivery company and a customer checks the gluten-free box on your signup form, you could then send them emails with helpful gluten-free cooking tips. 

Heads up: you can only create advanced segments with a Standard or Premium plan. Otherwise, you’re limited to regular segments—you can still set criteria, but you can’t nest them within each other.

Of course, with great segmentation power comes great complexity, and managing users within Mailchimp can be a bit overwhelming due to the multiple setup steps, especially for beginners. Constant Contact, on the other hand, keeps things simple by only using Segments and Tags showcased in a simple, easy-to-use interface:

In the end, Mailchimp’s segmentation system allows for a bit more flexibility and customization, as long as you’re ok with a slightly steeper learning curve. 

Constant Contact’s simple reporting is more straightforward, while Mailchimp offers extensive features

Email marketing attracts analytics-obsessed folks. Why? Because the variables are fairly limited, and almost everything is trackable.

Mailchimp boasts a slick reporting interface with an intuitive chart, along with list-wide or campaign-specific graphs. Their Content Optimizer, available with the Standard plan, analyzes your content and provides recommendations based on industry best practices, which some might find helpful. 

With its Standard and Premium plans, Mailchimp offers Comparative Reports, which let you track and compare campaigns at a deeper level. These reports could be helpful for a marketer without much analytics experience, but with the higher price tag, it’s a tough sell.

Meanwhile, I found Constant Contact’s reporting interface simple and intuitive—especially for beginners. Their bar charts provide all of the most important stats in an easily comprehensible way. 

Overall, Constant Contact takes a straightforward approach to reporting, while Mailchimp provides you with the tools needed to dive deep.

Mailchimp offers more A/B testing variations 

Constant Contact only supports subject line testing. And while subject lines are important for optimizing open rate, savvy marketers will want more. Mailchimp’s A/B tool lets you test subject lines, send name, send time, body content, or any combination of the above.

Additional features that set Mailchimp apart include their Send Time Optimizer that calculates the time of day your users most often engage with emails based on previous campaigns and their paid Timewarp feature that lets you send a campaign at the same local time for different time zones. Note that you’ll have to use the Standard plan or higher to access either feature.

Mailchimp’s advanced automation sets it apart from Constant Contact

In Constant Contact, you have the option to use three automations (welcome, birthday, anniversary) as well as multi-step automations when a customer opens an email, clicks a link, or joins a list. Additionally, you can connect your eCommerce platform in order to send abandoned cart reminder emails. You need the Standard plan for most single-step automations and the Premium plan for custom automations. 

Mailchimp offers the same marketing automation options, along with 40+ pre-built journeys. For example, you can provide shipping confirmations, schedule emails over time using a drip campaign, send split test emails, or learn why an order was canceled—almost anything you can think of, Mailchimp can do. 

To create an automation in Mailchimp, you can select from one of the pre-built customer journeys, or use the Customer Journey Builder (available with the Essentials plan) to create your own custom workflow. 

Both apps integrate with Zapier

Each of these email marketing apps has hundreds of native integrations, but you can integrate both Constant Contact and Mailchimp with Zapier to open up connections to thousands of other apps. That way, you can automatically send new leads to your lists or add new subscribers to the other apps you use most.

Mailchimp offers far more AI features

Constant Contact recently rolled out their AI Content Generator, which is basically a wrapper for GPT-created content. It’s included in every plan “for now,” which is only slightly ominous. 

You can choose from three format options (announcement, product promotion, or newsletter) and five tone options (default, professional, enthusiastic, informative, approachable, or persuasive). And that’s it—you can regenerate the copy, but you can’t give it any further directions or context to improve it specifically.

While the feature was easy enough to use, I wish it was built into the email builder instead of a separate interface. 

At the very least, it’s a jumping-off point, but since you have limited options for personalizing the output, I don’t see much value in this feature. You’re better off using ChatGPT (for free) and then pasting your generated copy into the Constant Contact editing interface. It’s the same technology powering it anyway.

But there are a few more AI-powered tools that can make using Constant Contact a bit more efficient:

• BrandKit: Link your site URL, and it will pull the logo, colors, and notable imagery from your site so you can add them to your email campaigns.  

• Campaign Builder: Answer a quick series of questions, and it will create the blueprint for a multichannel marketing campaign, complete with a timeline for action items.  

• Spam detection: This feature improves email deliverability rates by using smart insights to filter out suspicious content.

Mailchimp, on the other hand, offers 20+ AI features in-app, going beyond content creation and into AI insights for things like send time optimization, predictive segmentation, and product recommendations.

Like Constant Contact’s BrandKit, Mailchimp’s Creative Assistant will generate your logo, brand colors, and fonts based on your website’s branding. Where Mailchimp outperforms Constant Contact is that it also creates new designs, impressively including basic animations.

Standard plan users and above also have access to Mailchimp’s next-gen Intuit Assist, which puts additional AI directly into the platform using a combination of in-house and third-party AI models. It’s currently in beta and only available to select users, which didn’t include me, so I wasn’t able to test these features myself, but the idea is that it’ll be an all-in-one AI email marketing assistant.

Intuit Assist will automatically generate emails and branded designs/templates, analyze campaigns, and offer recommendations. Right now, it’s not clear how these features will affect pricing, as Mailchimp only gave a vague explanation in their announcement: “Intuit Assist is currently available at no additional cost to Intuit customers. Access to certain enhancements may be subject to Mailchimp plans.”

Constant Contact goes above and beyond with customer service

Constant Contact pushes its phone and live chat support, especially for new customers. In fact, I even received a call from them shortly after setting up my account, along with an email featuring helpful marketing ideas. I did start to get a tiny bit annoyed with the multiple follow-up calls I received (unsolicited phone calls give me anxiety, ok?), but if you’re new to email marketing, I could see how it might be helpful.

Meanwhile, Mailchimp highlights its Help Center when first seeking support, and for good reason: I found that their well-written articles and tutorials answered most of my questions. For questions not answered by the Help Center, they offer live chat support on weekdays and email support 24/7 for all paid accounts (as well as free accounts within 30 days of opening).

So the biggest difference is phone support, which Mailchimp only offers with their Premium plan. Although phone support doesn’t offer any obvious advantages over live chat, some people much prefer speaking to someone on the phone. Constant Contact is the clear choice if you count yourself in those ranks and don’t want to pay extra for it.

Both Constant Contact and Mailchimp offer extra features outside of standard email marketing

• Landing pages: Mailchimp and Constant Contact offer landing page builders (although Mailchimp’s is free to all users). 

• Social media posting: Constant Contact lets you post to your Facebook, Instagram, and LinkedIn accounts. For those disappointed by a striking single-letter omission from that list, Mailchimp gets points here for support for posting to Facebook, Instagram, and X, although it won’t pull report data for X.

• Instagram and Facebook ads: Both platforms provide tools to design Facebook and Instagram ads. 

• Surveys and polls: Both Mailchimp and Constant Contact offer survey tools that allow you to embed customer surveys into emails.

• SMS: Standard Constant Contact users have the option to add SMS starting at $10 per month for 500 messages; Premium users get this service for free. Mailchimp lets users add 1,000 SMS credits per month for $20. So, you get the same value from each, but Constant Contact is a little more accessible if you don’t need to send more than 500 messages in a month.

Constant Contact vs. Mailchimp: Which is best for you?

Constant Contact is better than Mailchimp for email marketing novices: their phone support, ready-to-send templates, and intuitive reporting offer a leg up for the less tech-savvy. Mailchimp, on the other hand, has an impressively robust feature set that users with experience in email marketing will benefit from.
