EMAIL SPAM CHECKER
Know where your emails will land before you hit send
Amplemarket checks connected mailboxes weekly and flags spam placement before it hurts outreach.

“What sets it apart is the built-in deliverability suite; our sequences actually hit the primary inbox, not the spam folder.”

Inbox placement testing
Automated tests that catch spam issues before your prospects do

Every mailbox tested, every week
Automated test emails check whether each mailbox lands in inbox or spam. No manual setup required.

Unhealthy mailboxes flagged instantly
If a mailbox fails, it gets flagged in your Domain Health Center and during sequence prep so you never send from it by accident.
Rest, recover, and send again
Flagged mailboxes recover faster with the Deliverability Booster enabled. Amplemarket unflags them once they pass the next test.

Every connected mailbox is tested automatically with no manual effort.

Frequently asked questions
What are Email Placement Tests?
Email Placement Tests are automated weekly checks that Amplemarket runs on every connected mailbox. Test emails are sent to fresh mailboxes to evaluate whether your emails land in the inbox or spam folder. If a mailbox is flagged as unhealthy, Amplemarket warns you before you use it for outreach.
How often are placement tests run?
Tests run automatically every week across all connected mailboxes. You don't need to trigger them manually. Results are updated in the Domain Health Center and reflected in the sequence prep flow.
What should I do if a mailbox is flagged as unhealthy?
Rest the flagged mailbox by pausing outreach and enabling the Deliverability Booster to help restore reputation. Avoid adding new volume to flagged mailboxes. Amplemarket will automatically unflag the mailbox once it passes the next weekly test.
Will I see test emails in my mailbox?
You may notice automated test emails in your connected mailboxes. These are part of the weekly placement test cycle and are normal. They are sent to controlled test mailboxes, not to real prospects.
How do placement test results connect to Mailbox Recommendation?
Placement test results feed directly into Amplemarket's Mailbox Recommendation. When selecting mailboxes for a sequence, unhealthy mailboxes are flagged so you only send from addresses with strong inbox placement.
