Frequently Asked Questions

Common questions about Flex SMTP

Yes. Flex Forms now calls wp_mail() only. Activate Flex SMTP once to copy the old Forms SMTP options, then manage delivery here.

No. Those providers use SMTP with an app password (and SMTP AUTH enabled on Microsoft 365). OAuth is not included.

SMTP talks to the provider’s mail server through PHPMailer. HTTP API posts the message with wp_remote_post and skips PHPMailer. Use HTTP API if outbound ports 465/587 are blocked. Gmail, Microsoft 365, Yahoo, Zoho, iCloud, and Custom are SMTP only.

Not while Enable is on. Messages go to your SMTP host or the provider API. Turn Enable off to return to the default WordPress mailer.

Recipient, subject, success or fail, error text, and time. It does not store API keys or passwords. Disable Email log if you do not want delivery history.

Deleting the plugin removes settings, credentials, and the log table. Deactivating alone keeps your data.
