This tutorial solves a lot of (WordPress) email issues. Using SMTP for WordPress take a little setup, but everyone should learn how to do this! We share a great free solution using the WP Mail SMTP plugin. This is super useful when using a cloud VPS, such as the popular options from Cloudways, Digital Ocean, Vultr and Linode.
This will fix a number of common issues such as:
WordPress WooCommerce emails not sending
WordPress emails going to junk
WordPress password reset email not sending
WordPress contact form email not sending (e.g. WP Forms, Contact Form 7)
