A lot of site owners face the spam mail problem for using the WordPress default PHP mail function(). When it comes to mail service there may be some restrictions: sometimes emails are not delivered, sites cross the limit of outgoing mail. Bit SMTP plugin allows you to authenticate the mail service of your site by configuring the SMTP server of your desired mail service. SMTP is a protocol that helps your WordPress site to make its email deliverability more easygoing & reliable. By enabling this feature you can send mail from your site to your recipients via your preferred mail server.
