Mailer status, connection tests, domain checks and failure logs for WP Mail SMTP.
Answers the question a silently broken site can't: can it send mail at all. The active mailer and whether it is fully set up, the From address, recent failures, a connection test that delivers nothing, and SPF, DKIM and DMARC checks.
The active mailer and whether it is fully configured.
Drives the provider session without sending anything.
SPF, DKIM and DMARC for your sending domain.
The last failure and errors logged over a period.
One real test email, when you ask for it.
API keys, passwords and tokens are never returned.
Ask in plain language and the WP Mail SMTP integration turns it into typed calls — no exports, no SQL, no brittle scripts.
Find why order emails stopped and test the fix in one conversation.
Check mailer setup, recent failures and your domain's SPF, DKIM and DMARC.
Anything permanent asks for confirmation first, and every call is logged.
