Email service providers (ESPs) don't tell you where your mail lands — they only confirm SMTP delivery. But a message that lands in the Spam or Promotions tab is effectively invisible to recipients. Before blaming creative or audience, you need hard data on placement.
This test gives you that data in minutes: send one email to our seed addresses across Gmail, Outlook, Yahoo, Mail.ru and Yandex, and we report placement plus authentication results (SPF, DKIM, DMARC) so you can fix the right thing first.
What you get in the report
- Placement per provider — Inbox, Spam, Promotions, or Not received
- Authentication — SPF, DKIM and DMARC results parsed from headers
- Spam score — when the provider exposes it (e.g. SpamAssassin X-Spam-Score)
- Subject & From — to verify threading and impersonation setup
- Recommendations — concrete next steps to improve deliverability
- Live updates — results stream in as seeds receive the mail
Frequently asked questions
What is an inbox placement test?
It sends your email to a set of seed mailboxes across major providers (Gmail, Outlook, Yahoo, Mail.ru, Yandex) and reports where each copy landed — Inbox, Spam, or Promotions. It's the deliverability equivalent of a smoke test.
Is this test really free?
Yes, completely free. Up to 3 tests per email and 10 tests per IP per day, with no signup required.
How long does a test take?
Most results arrive within 2–10 minutes. The page updates live via SSE as each seed mailbox receives the email.
Which providers are tested?
Gmail, Outlook/Hotmail, Yahoo, Mail.ru and Yandex. These cover the vast majority of consumer and business recipients in both Western and CIS markets.
Do you store my email or test content?
Only the subject, From-header, and authentication/placement results are stored — enough to render the report. Raw bodies are not retained and all test records are purged after 7 days.
What if I need higher inbox rates automatically?
That's what LDM Platform and the LDM API are for — managed warm-up, rotation, and inbox-verified delivery with 85%+ placement out of the box.
