WordPress uses the PHP mail function to send emails generated by WordPress. The PHP mail function sends emails over the IP of your hosting provider’s servers which can have a bad reputation and be blacklisted by many email providers like Gmail, Yahoo, Office 365, Zoho, etc. causing your WordPress originated emails to land in the SPAM folder of your users. By using GoSMTP you ensure that your emails reach the inbox of your user(s).
