WP Mail SMTP helps your WordPress site send emails.
In order to send emails from WordPress and ensure their receipt from mail servers, your site will need a working E-Mail plugin. Years and years ago in the 00’s, a website could just send out an email and it would work. But fast forward 15 years and the arms race around spam has made this completely impossible. WordPress will think it’s sending e-mails, but they will never make it through spam filters and get delivered.
Even if you don’t use a contact form on your site, it still needs to be able to send transactional e-mails out, for example if you forget your password and try and reset it, that won’t work unless WordPress is able to get the password reset link to you via e-mail.
The solution to this is to use WP Mail SMTP plugin, which will add the necessary stuff to e-mails that they can deliver. Using the pro version of WP Mail SMTP, you can even send e-mails out your incoming e-mail provider (including G Suite or Office 365).
