7 Best Free SMTP Services to Consider in 2022

To have an effective email marketing tactic, you need a reliable email service that you'll be sure emails are received from the recipients' inboxes.

The best free SMTP service provides you with a great way to deliver your marketing content and keep your subscribers updated on your latest deals or products.

You may find a lot of free SMTP services available online, but they could not be perfect to use for the kind of business that you have.

Finding a decent free SMTP service may be a little tricky if you are uncertain whether it would work well in your business.

To make your search a little easier, we've put together a list of the best free SMTP services in 2022.

Each of these providers has been carefully selected based on its features. But before that, let's first learn the basics of an SMTP service.

What is an SMTP?

An SMTP (Simple Mail Transfer Protocol) is a protocol that's used to send emails. It's the most common way to send emails, and it's what most email providers use. The emails in your inbox could probably be from any number of different SMTP servers.

Do You Need an SMTP Server?

If you're not sure whether you need an SMTP server, ask yourself the following questions:

  • Do I need to send bulk emails?

  • Do I need to automate my email marketing campaigns?

  • Do I need to track my sent emails?

  • Do I need to use a custom domain for my emails?

  • Do I need to send emails from a web application?

If you answered yes to any of the above questions, then you need an SMTP server.

One of the most common issues with sending emails is the "bounces". This can happen for a number of reasons, but the most common reason is that your email server is not configured correctly.

An SMTP server will take care of this for you and make sure that your emails are delivered correctly.

Another great benefit of using an SMTP server is that you can track your sent emails. This is a great way to see how many people are opening your emails and what actions they're taking.

Now, let's narrow down our options to the best free SMTP services available in 2022.
