Comparison
VuloMail vs Solid Mail.
Solid Mail, formerly WP SMTP, is free and does the basics well: five API providers plus manual SMTP, multiple connections chosen by From address, a fallback, and an email log. It was last updated in May 2026 and is listed as tested up to WordPress 6.9.10, behind the current 7.1.3. VuloMail supports far more services and adds alerts, diagnostics and SMS.

Switching
Moving from Solid Mail.
Add the same account
Add the provider you use in Solid Mail as a VuloMail connection. Nothing changes until you set it as primary.
Set it as primary
Optionally add a backup connection, so a second provider takes over if the first fails.
Send a test
Tools → Send a test email goes through live routing. Diagnostics confirms your SPF and DMARC records.
Deactivate Solid Mail
Two plugins handling the same email compete for it. VuloMail's Diagnostics flags any it recognises.
