Email
spam tester
Send a real email to a curated seed pool across multiple providers. We watch which folder it lands in — inbox, spam, promotions, updates — and score your placement out of 100.
- Copy the test subject below — you must use it exactly. The subject contains a unique token so we can match the email back to your test.
- Send your email from your own client (Gmail web, Outlook, your sending platform, etc.) using that subject. Address it to every seed address below — you can paste the comma-separated list straight into BCC.
- Wait for results. We poll every minute. Detection typically completes in 2–10 minutes depending on provider.
