SMTP, short for Simple Mail Transfer Protocol, is a protocol used for sending and receiving emails. A WordPress SMTP plugin lets you use an alternative method for sending emails that has a much better deliverability. In simpler terms, a WordPress SMTP plugin helps you make sure people actually get the emails that your WordPress site sends to them.
There are different plugins to choose from that are related to SMTP. The most commonly used ones are wp mail smtp, easy wp smtp, gmail smtp, smtp mailer and wp mail bank.
