By default, WordPress uses the PHP Mail function to send emails. However, it is not the best method and may decrease email deliverability. Emails may often arrive in the spam/junk folder. As an alternative, you can use SMTP to send emails.

In order to send emails via SMTP follow the steps below:

Choose an SMTP server

There is a wide range of free SMTP servers that can be set up on a mail client to deliver your emails. For further information about SMTP servers please refer to this article.

Register for the SMTP server
