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.
