Mailchimp offers its clients free membership, a great number of features, a user-friendly interface of dashboard, and email templates. It provides a good analytics solution and several mobile applications to develop and send emails. All you need to start work with Mailchimp is to set up an account. No wonder that a lot of people prefer Mailchimp’s other services.   

Constant Contact is another popular solution for your email marketing. It offers a free trial version and a wide range of functions. For example, you can send targeted sets of emails and make them personalized. Its interface concedes Mailchimp but there are a lot of marketers that like to work with it. 

Both Constant Contact and Mailchimp are designed for setting the communication between companies and their customers, selling the products, and re-attracting customers. 

Let’s compare the main features of these services to simplify your choice of the best solution for email marketing. Constant Contact vs Mailchimp: who wins in this battle?

#1. Automation

It is a basic feature for email marketing that allows marketers to create and send emails to multiple users at the same time. A special set of triggers helps specialists to define the type of emails. How does it work? You don’t need to write a personalized email for every new visitor of your site: with this feature, you create a template and the system sends this letter when it is needed.

Mailchimp allows you to automatically send emails with personal recommendations about products and purchase follow-ups. You can activate these functions when customers buy the product, click a certain link, or leave the cart.

Using Constant Contact you can customize autoresponders and personalized emails, but its automatization features are limited.

Score: 1-0 in favor of Mailchimp! Its automation is more flexible and includes more features.

#2. Deliverability

Brand’s reputation, content, and authentication influence on your email deliverability. Your email strategy can’t effectively work if all your emails are perceived as junk mails. 

Mailchimp uses a special program to detect abuses before sending emails, it calls Omnivore. Omnivore guarantees that customers will get appropriate content that allows the marketing department to increase the productivity of their emails to 96-99%.

Constant Contact also uses mechanisms for spam detection, with its help you can predict and address any problems with deliverability. The efficiency of Constant Contact is up to 98%. 

Score: 2-1 in favor of Mailchimp, but in this round, both services showed us similarly high results.

Registration forms help you to check the customers’ interest in your products and offers.

But you should use it properly, there is the risk to spam a host’s mailbox without appropriate address validation. As a consequence, you can get a needed subscriber list or break it down and undermine all your business. Hence, you need to be sure that your registration forms are made properly.

With Mailchimp, you can customize your registration forms according to your needs, use a variety of custom fields, drag and drop functions. The only condition is to adhere to the HEX color code.

Constant Contact also supports font and background color customization. It allows specialists to create QR code for your registration form. The drawback of Constant Contact is that its fields use only usual tick boxes for the company’s name, customer’s name, etc.

Score: 3-1 in favor of Mailchimp. Mailchimp wins this round: it is more flexible and offers more features for customization.

#4. A/B Testing

A/B testing is necessary for email marketing: you should test what your customers like and create your winning combination: themes, texts, images, send time, kinds of the call to action, etc.

Mailchimp offers three kinds of its free plan, so you have the ability to send your emails to small groups and test your emails work.

Constant Contact is less user-friendly for testing automatization: if you want to experiment with several versions of your email, you should customize it manually. 

Score: 4-1 in favor of Mailchimp. This service allows you to save your time and achieve good results from testing with less effort. 

#5. Emails design

Mailchimp allows marketers to choose different easy-to-use parameters of template and image customization. Also, it provides unlimited storage for images.

Score: 5-2 in favor of Mailchimp. We gave points for both services because they have their own benefits, but the flexibility of Mailchimp can be the decisive factor for somebody.
