Why is WordPress not sending emails?  

Incorrect Server Configuration

The most common cause of emails not being delivered is that your WordPress hosting server is not configured properly to use the PHP mail() function.

Many email service providers such as Gmail and others use a number of filters and tools to reduce email spam, even if your hosting account is configured to do so.

These anti-spamming softwares try to identify that an email is actually coming from the location that it claims to be from. WordPress-generated emails often fail this test.

This means that emails sent to users from your WordPress website (by using a plugin like contact form or sending an admin notification, for example) are unlikely to even make it to their inbox, at all.

For this reason, we don’t recommend using WordPress for email newsletters..!

Emails are being sent, but going to spam

Make sure that emails sent from WordPress don’t end up in spam folders.

Users who report WordPress is not sending emails may simply be experiencing spam problems.Tell them to check their spam folders for WordPress emails.

Several email clients might view WordPress emails as spam because they’re automated.

WordPress not sending emails due to Contact form plugins

Email clients sometimes regard emails sent by contact form plugins as spam.

Usually, email clients mark them as spam because of the difference in addresses between the “From” address and the delivery box address. This is usually the case when you set up your contact form to send emails. In the “From” field, the user entered their email address. Although the email is sent from WordPress, it is flagged as suspicious by email clients.

Consequently, it will be classified as junk mail.

Hopefully, tweaking the settings of your contact form plugin will fix this issue. 

Troubleshooting the WordPress Not Sending Emails Issue

Ask Your Users to Whitelist the Email Address

In the industry, SMTP (Simple Mail Transfer Protocol) is the standard for sending emails. In contrast to the PHP mail() function, SMTP uses proper authentication, so emails can be bettered delivered.

It is possible to use SMTP providers for free (such as the Gmail SMTP server): so you don’t have to spend any money on this.
