Email Deliverability Test
Send a test email to the address below — sender.report checks SPF, DKIM, DMARC, spam score and more in seconds.
Secure – no effort required
Your test email arrives – like any email – in plain text first and is immediately analysed (SPF, DKIM, spam score and more). Only for this tiny moment is its content exposed – usually just a fraction of a second. Right after that it is encrypted; from then on only your key can open it.
-
Your link is the key. The decryption key lives only in your personal link. Only those who have it can open the report – not even we can read it.
-
You decide who sees it. Share the link and you share access. Keep it to yourself and everything stays private.
-
Disappears on its own. No account, no password, no traces – your mailbox and all data are deleted automatically.
