Inbox / Spam Tester
Send a real email to a one-time address and we'll score how likely it is to reach the inbox — DKIM, SPF, DMARC, blocklists and content, out of 10. Test several senders at once.
1 Send an email to each address
Send from the real system or inbox you want to test — one email per address.
2 Then check the results
Each address is valid for about 30 minutes. Nothing is sent from here — we only read what you send in.
How the score is calculated
You send one real message to a one-time address and the checks run against what actually arrived, rather than against your DNS in isolation. That matters because a message can have perfect records and still be filtered on content, or be signed correctly and fail alignment.
- What is in the score?
- Authentication results as the receiver computed them - SPF, DKIM and DMARC alignment - plus blocklist status for the sending IP and a content assessment. Authentication is the largest share, because a failure there is the only part that can stop delivery outright.
- I scored well but mail still goes to spam.
- The score measures what can be checked from one message. Reputation cannot be: it is built from your volume history, complaint rate and engagement over weeks. A new domain or IP starts with none, so early mail is scored strictly no matter how clean the message is.
- How long is the test address valid?
- Each one is single-use and expires shortly after. Nothing is stored beyond producing your result, and the address cannot be reused to send a second message.
