Frequently asked questions
How does Solid Mail Help You Implement SMTP Email on your website?
Solid Mail makes connecting to many popular SMTP services straightforward and clear. Solid Mail currently supports Sendgrid, MailGun, Brevo, Amazon SES, Postmark, and manual connections. This allows you to connect to any Email Service Provider (ESP).
Why Should You Use an SMTP Plugin for Your WordPress Website Instead of the Native PHP Mail?
WordPress uses PHP’s built-in mail function, which is limited by your server and often lacks dedicated monitoring. Many hosts do not offer email services or actively monitor for deliverability, leading to emails not reaching the inbox. An SMTP plugin like Solid Mail, combined with an email service provider, helps ensure email delivery.
