Drive sales on autopilot with ecommerce-focused featuresSee Features
So you want the ability to send a high volume of emails to your customers and potential customers?
And you want to be able to send them for free, or at least get value for money?
Then you need a mass email service, otherwise known as a bulk email provider.
At first glance, it’s easy to think all mass email service providers are the same.
But as you’ll soon see, this isn’t true. The platforms differ in a number of ways, including: what features they provide, how those features are distributed between their free and paid plans, limits on how many emails can be sent, whether other channels (like SMS) are included, and pricing.
In this article, we’re going to show you the best mass email platforms and some of their differences.
Let’s take a look:

As the above table shows, there’s a lot of variation even between just these 10 bulk email providers.
