What is an email deliverability test?
A deliverability test sends a copy of your email to a set of seed inboxes across the major providers, then reports where each copy landed. Instead of guessing why opens are low, you see the actual placement: inbox, promotions, or spam.
What this test checks
The report shows which providers put your email in the inbox and which filtered it, plus the authentication and reputation signals behind that result.
- Inbox vs. spam vs. promotions placement, per provider
- SPF, DKIM and DMARC authentication status
- Whether your domain or IP is on a blacklist
- Spam-trigger content in the subject or body
Why emails land in spam or promotions
Most filtering comes down to a few things: failed authentication, a domain or IP with a poor sending history, spam-like content, or sending to addresses that bounce. A test tells you which of these is hitting you so you fix the right one.
Frequently asked questions
What is an email deliverability test?
It sends your email to seed inboxes across the major providers and reports where each copy landed, so you can see your inbox placement before a real send.
Is it free?
Yes. The test runs with no signup and no card.
Why do my emails go to spam?
Usually failed authentication, a domain or IP with poor sending history, spam-like content, or sending to bad addresses. The report points to which one applies to you.
How do I improve a low score?
Fix whatever the report flags first — set up SPF, DKIM, and DMARC, clean your list, and warm up the domain if its reputation is low.
Does this affect my real sender reputation?
No. The test sends to seed inboxes, separate from your live sends.
Which providers does the test cover?
Gmail, Outlook, Yahoo, and iCloud, plus other major providers.
