Best SMTP Services To Use On Your WordPress Website To Send Email

SMTP WordPress Email

Sending email is vital for any business looking to grow their customer base. But what services should you be using? We’ve compiled a list of the best SMTP services to use on your WordPress site to send email.

The best part? All of these services integrate with Groundhogg, making it easy to deliver email to the inbox and monitor bounces, complaints, and other email performance metrics.

What is SMTP?

SMTP stands for Simple Mail Transfer Protocol. It is a protocol that used to be the standard way of sending emails through SMTP services. 

However, as technology continues to improve, it has now become more of a marketing term. This is because email-sending providers now offer faster API-based alternatives. 

So keep that in mind while browsing through this list.

Why do you need a good email-sending service?

Having an SMTP/ email-sending service is a vital part of ensuring your messages end up in the inbox. Here are some benefits you’ll want to consider:

Improved deliverability & managed reputation

Bulk sending services manage their IPs carefully and closely, making sure that customers are sending reputable emails. By sharing IP address among thousands of businesses, these bulk email companies can provide a better baseline email reputation than the one that comes with your own website hosting.


Email sending services manage their uptime carefully and have invested significantly in providing super fast email delivery, so that when you have a spike in outgoing email they are ready to handle it.

Many hosting companies will actually throttle or outright block your server’s SMTP port for sending too much email, which can be damning if you’re in the middle of a sale or promotion.

Email Feedback

Email services will typically send feedback about an email you sent if it fails to reach the inbox (bounced) or if it was marked as spam. Your server’s MTA doesn’t do that!


Email sending is a bit of a commodity now, so there are no shortage of good deals. There are many levels of pricing available to help you start sending emails to your subscribers.

Here are out top choices for outgoing bulk email services.
