WP SMTP can help us to send emails via SMTP instead of the PHP mail() function.
It adds a settings page to “Dashboard”->”Settings”->”WP SMTP” where you can configure the email settings.
There are some examples on the settings page, you can click the corresponding icon to view (such as “Gmail””Yahoo!””Microsoft””163″”QQ”).
If the field “From” was not a valid email address, or the field “SMTP Host” was left blank, it will not reconfigure the wp_mail() function.


WP SMTP plugin was originally created by BoLiQuan. It is now owned and maintained by WPOmnia.

With the addition of a default Reply-To, it would be perfect for the websites I install SMTP plugins on.

Settings got messed up upon automatic update without any kind of alert/notification for re-entering the login/authentication details. No wp-mail fallback when settings got misconfigured. One whole week of emails lost and complaints from our customers. Thank you

In the most recent update around April 2022, they pushed a release that made the plugin not work because the update erased your credentials. And they admit knowing it would happen. But there was no warning, no note to make note of your credentials before the update. Many other plugins push warnings like “Major update – backup your site before updating” or “This update is not backward compatible with the last version”. They could have done something like that. THEN they keep saying this isn’t an issue, as if they have no responsibility for this, and it is not their fault. How is NONE OF MY EMAILS ARE SENT after the update not an issue??? Yes this IS your fault, because all I did was update. The plugin has one job to send emails and after updating this doesn’t happen. Yes it can be fixed and sure it’s a good thing to encrypt the credentials, but my site and many others went a week or more without sending out any emails. Because they didn’t warn us that we had to do other things for it to work. Read the support tickets for April 2022, you’ll see so many people reported this. And they just kept saying “Not an issue”. So now I can’t trust them for future updates to not just break the plugin and not tell me.

Took me some time to discover how to resolve the ‘problem’ authenticate your SMTP account. So, for the girls/boys who encounter the same problem: Login to your ZOHO account / My account / (enter your password) Security / App Passwords . (Application-specific passwords are passcodes that give applications like email clients permission to access your Zoho Mail.) Create new Password / Enter the app name / then click Generate. Save the shown password to a safe place and use THIS password in the plugin. So do not use your password of your ZoHo account.
