FAQ

WordPress uses PHP mail. The reliability of WordPress email ultimately depends on the configuration of your host’s mail server.

But most web hosts don’t monitor email activity on their servers. That means if you have a noisy neighbor on your web host who sent spam emails and ended up blacklisted, your server’s IP gets blacklisted. And that hurts you, too: Your emails may be more likely to be rejected or flagged as spam.

Using an SMTP email provider can help resolve deliverability issues. Solid Mail makes it easy to connect to an SMTP service provider like SendGrid, MailGun, Amazon SES, Brevo, or others. This helps you comply with industry best practices and go from spam folder to inbox in minutes.

SMTP stands for Simple Mail Transfer Protocol. It’s designed to reliably deliver emails with advanced authentication and encryption capabilities compared to PHP.

Currently, Solid Mail supports the following email service providers:

SendGrid
Postmark
MailGun
Brevo (formally Sendinblue)
Amazon SES
Manual connection (connect to any 3rd-party email service provider)

We are adding more SMTP services in the future. Stay tuned! If you have services you’d like us to prioritize, let us know.
