Emails are the preferred method of transferring information online, and it makes sense that email would also be an essential part of running and managing a successful WordPress site. SMTP, or Simple Mail Transfer Protocol, is a simple communication protocol that allows the transfer of email over the internet. In addition to making your website’s email more secure, having the SMTP gateway helps prevent WordPress emails from being blocked by popular free email providers like Gmail.
Having a reliable SMTP plugin is a good idea for any WordPress site. These plugins allow the site admin to choose which SMTP service to use and bypasses the normal WordPress email functionality. While a SMTP plugin can seem very technical, it is ideal for all types of WordPress users.
