Every entry is saved under Forms → Entries first, then emailed to the addresses you set. If an email fails, the entry is still there and you can resend the alert.

Your server’s default mail is often filtered as spam. Send through Gmail or your mail provider with an SMTP plugin, such as the free StackMime Mail.

Yes. The form gets a fresh one-time token from the REST API when the page loads and is sent with POST, which page caches and CDNs never store.

No. Spam is stopped with invisible checks that real visitors never notice. Suspected spam is kept in the Spam view for 30 days, so nothing is lost by mistake.

Choose Clean or No styles under Forms → Settings, set an accent colour, or override the –smf-accent custom property and the .sm-form classes in your theme.

Nothing is deleted unless you switch on “Delete all forms, entries and settings when the plugin is deleted” in the settings.
