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.

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 60-day free trial, regardless of the number of subscribers or emails sent). Mailchimp, on the other hand, remains free up to 500 contacts and 2,500 sends per month.
After the free introduction, both Mailchimp and Constant Contact offer unlimited email sends, with pricing tiers broken down by number of contacts. Here's how they compare for their basic plans:
Number of contacts | Mailchimp Essentials | Constant Contact Core |
---|---|---|
500 | Free | $9.99/mo |
2,500 | $34/mo | $35/mo |
10,000 | $87/mo | $80/mo |
25,000 | $225/mo | $155/mo |
50,000 | $299/mo | $300/mo |
They're pretty comparable except when you fall into that 25-50k contacts range, where Constant Contact is noticeably less expensive.
Each app also offers more advanced plans with extra features:
Mailchimp Standard | Mailchimp Premium | Constant Contact Plus |
---|---|---|
- Journey automations - Retargeting ads - Custom-coded email templates - Advanced audience insights
| - Advanced segmentation - Multivariate testing - Multi-user access - Phone support
| - More customer list growth tools - Automated emails - Auto-generated segments - Conversion and sales reporting - New customer kickoff calls
|
Here are the price breakdowns of each of these upgraded plans.
Number of contacts | Mailchimp Standard | Mailchimp Premium | Constant Contact Plus |
---|---|---|---|
10,000 | $115/mo | $299/mo | $125/mo |
50,000 | $299/mo | $359/mo | $410/mo |
150,000 | Contact limit exceeded | $1,050/mo | $810/mo |
Constant Contact's advanced plan lands somewhere in 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's new email builder makes designing incredibly easy: you can edit everything simply by clicking on each content block, which I found to be much easier and faster than the classic editor where you click on a block and then edit in the sidebar.
Another much-needed feature they've added is undo and redo buttons, which are perfect for indecisive and mistake-prone designers like myself.

Meanwhile, the Constant Contact email builder is comparable to the traditional 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).

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.

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 new Content Optimizer, available with the Standard plan, analyzes your content and provides recommendations based on industry best practices, which some might find helpful.

With their Premium plan, 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.
A couple other features that set Mailchimp apart: their Send Time Optimizer will calculate the time your users engage most often based on previous campaigns, and their paid Timewarp feature lets you send a campaign at the same local time for different time zones.
Mailchimp's advanced automation sets it apart from Constant Contact
Constant Contact offers three single-step 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. These automations are simple and easy to set up, but they're also limited (and only available with the Plus plan).

Mailchimp offers the same 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 below, or use the Customer Journey Builder (available with the Essentials plan) to create your own custom workflow.

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 super 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: Mailchimp provides social media tools that allow you to connect your Facebook, Twitter, and Instagram accounts; Constant Contact offers those same platforms plus LinkedIn.
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.
Constant Contact vs. Mailchimp: Which is best for you?
Ultimately, Constant Contact is a better fit for email marketing novices: their phone support, ready-to-send templates, and intuitive reporting offers 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.
