Do you want to build an email list, but haven’t yet decided which email marketing service you are going to use? We’ve all been there, browsing through different email marketing services sites, trying to figure out which has the best features for your business. While we can’t go through all the email marketing services out there, we are going to take a look at the three most dominant email marketing services— Campaign Monitor vs Mailchimp vs Sendinblue.

Campaign Monitor vs Mailchimp vs SendinBlue

We’ll take a look at the features that these email marketing services offer and give you an insight into the best email marketing service to consider. Let’s get down to business.

Campaign Monitor 

Email Marketing Email Software Campaign Monitor

Campaign Monitor is one of the recommended solutions on our list. As it belongs to the list, it has the ability to use email marketing tools. It is a web application that creates data for an online mailing list. In addition to that, it can also send HTML e-newsletters too. 

Before, Campaign Monitor didn’t offer a free plan. As we looked upon the website, they are now offering a free plan just by signing up to their website. 

They also provide three different paid plans—basic, unlimited, and premier. While those three plans have some standard features, they differ in certain ways.

These are some of the key distinctions found in those plans:

  • Basic plans have a limit on the number of emails you can send to your subscribers in a single month. If you have an email list with 500 subscribers, you can only send 2500 emails a month. On the other hand, if you have a list with 30,000 email addresses, you can only send 250,000 emails. Also, with basic plans, you are limited to designing automated sophisticated subscriber journeys.
  • Unlimited plans don’t limit the number of messages you can send to your subscribers. These plans also offer sophisticated automated email journeys.
  • The premium Campaign Monitor plans boost unlimited plans by offering you phone support and send-time optimization. The latter is a feature that sends e-newsletters at specific moments when they are likely to get opened.

Since the pricing depends on the size of your database, we are going to give you an overview of three different scenarios that will help you understand Campaign Monitor pricing:

Note: These are monthly prices.

  • A database with 500 subscribers will cost you $9 in the basic plan, $29 in the unlimited plan, and $149 in the premium plan.
  • A database with 25,000 email addresses will cost you $199 in the basic plan, $399 in the unlimited plan, and $499 in the premium plan.
  • If you have a top-tier database with a list of 50,000 subscribers, you will pay $299 for the basic plan, $699 for the unlimited plan, and $989 for the premium plan.

Another email marketing tool recommended is Mailchimp. Mailchimp offers a free plan. This might be a suitable option if you want to try out Mailchimp features. It lets you host a mail list with 2000 addresses and allows you to send around 10,000 e-newsletters each month. However, your e-newsletters will have Mailchimp ads.

Paid plans are billed in the following way:

  • Standard– starts at $14.99 for a list with 500 email addresses.
  • Premium– starts at $299.99 for a list with 500 addresses.

However, the Essentials plan doesn’t let you automate your marketing emails through autoresponders. If you are keen on automation, you should consider the standard and the premium plan.

If you don’t send emails frequently, you can consider using the ‘pay as you go’ plan. This option allows you to pay a certain fee, depending on the number of emails sent. It is based on the essentials plan, so it has the same functionalities as the essentials plan.

Take note: watch out for your subscriber count while using Mailchimp.

Campaign Monitor vs Mailchimp vs SendinBlue: Which Email Marketing Service Should You Choose?

Now that you’ve gone through those three email marketing services, the next thing you need to do is to choose a suitable platform.

A little while ago, our favorite email marketing service was Mailchimp because it had a user-friendly interface. However, since Sendinblue upgraded its interface, it has become quite competitive. And you know what?

Sendinblue allows you to manage your email marketing features from your WordPress admin dashboard quite easily. While Campaign Monitor is a reliable email marketing service, we couldn’t find a solid reason to choose it over Mailchimp or Sendinblue. However, when it comes to automation and personalization, Campaign Monitor has some exciting features. Such features can only be useful if you are willing to put in the work. Campaign monitors might be suitable for you if you like such features.


While finding a fully reliable email marketing service can be a rather daunting task, the platforms we have recommended above have excellent features. If one doesn’t suit your needs completely, you can switch to another service and try out its functions. Eventually, you will find a suitable email marketing service that you are comfortable with. Which is your favorite email marketing service out of these three? Let us know in the comments below!
