While it can be a hassle to do the manual verification in order to set up a SendGrid account, the benefit of the service is well worth the effort.

Using SendGrid will solve most of the email issues one may encounter when using WordPress.

In addition, the SendGrid platform has numerous useful features like open tracking, click tracking, unsubscribe handling/compliance, branding, and logging.

There’s a free plan that’s adequate for most websites. As your website grows, SendGrid makes it easy to handle the increasing transactional emails. I highly recommend this service and plug-in.
