Why WordPress is not sending emails?
Before we find any solutions, we must answer this question, why WordPress is not sending emails? The main cause is PHP and mail(). In other cases, some plugins that block spam may consider your emails as spam, therefore, your website won’t send any emails.
In this case, even if you succeed to send an email, it will land in the “Spam” box. This is one of the reasons experts recommend not to send newsletter emails through your WordPress website. Below, we will discuss the best possible options to fix this problem.
How to Test WordPress mail server?
One of the basic methods to fix this problem is by testing your mail server. How can you test your WordPress mail server? To do so, you will need to use a simple plugin known as “Check Email”.
