How to Use a Free SMTP Server for WordPress Emails (7 Options in 2020)

free smtp server

If you’re having problems with sending and receiving emails from your WordPress site, using a free SMTP server can offer improved reliability and deliverability at no cost.

By default, WordPress tries to send transactional emails via PHP mail, which leads to all kinds of problems. Transactional emails are your site’s automated emails such as password resets, order confirmations, etc.

SMTP, short for Simple Mail Transfer Protocol, lets you send your site’s emails via a dedicated email server. This means your site can send emails more reliably and those emails are less likely to end up in users’ spam folders.

In this post, we’ll look at seven free SMTP server options that you can use with your WordPress site, including the free Gmail SMTP server.

For each option, we’ll briefly introduce you to it, share any limitations with the free plan, and show you how to set it up on WordPress.

What You Need to Use a Free SMTP Server With WordPress

To integrate any of these tools into your WordPress site, you’ll need a plugin.

Some of these tools offer their own dedicated integration plugins. If not, you can find several quality free SMTP plugins at, like Post SMTP Mailer/Email Log which is a 100% free relaunch of the popular Postman SMTP plugin.

For the tutorials below, we will use:

  • A service’s dedicated WordPress plugin when available.
  • Post SMTP Mailer/Email Log when a dedicated plugin isn’t available. You should be able to follow the same basic instructions with other plugins, though.

7 Free SMTP Server Solutions to Use with WordPress in 2020

Here are the free SMTP providers that we’ll cover – keep reading for more detail on each tool:

Gmail SMTP Server

You probably already know Gmail for its free email offering. However, Google also lets you use Gmail as an SMTP server to send emails from your website.

With a free Gmail account, you can send up to 500 emails per rolling 24 hour period. Or, if you’re a paid G Suite subscriber ($5 per month), you can send up to 2,000 emails during the rolling 24 hour period.

Setting up the free Gmail SMTP server is a little more labor-intensive than some of these other tools. However, the extra effort is worth it as Gmail also offers the highest free sending limit of any tool on this list.

You can use Gmail’s SMTP server information in a number of different places. You can use this in your local email client like Microsoft Outlook or within your WordPress site, which is what we’ll focus on.

To set up Gmail with your WordPress site, you’ll need to:

  • Create a Google app
  • Configure your WordPress site to send via the app using a plugin

If you want to send emails from a custom domain (e.g. [email protected]) instead of Gmail ([email protected]), you’ll first need to set up and pay for G Suite. We have an entire post on why we like G Suite, as well
