Free inbox placement test
See where your emails land—inbox, spam, or missing—across real provider inboxes. Send from your own Gmail or Outlook. Takes about two minutes to set up.
What is inbox placement testing?
Inbox placement testing means sending a message to special seed mailboxes and checking whether it lands in the inbox, spam, or does not arrive. It is different from SPF/DKIM checks: it measures real-world delivery from your sending path and IP reputation, not your DNS records alone.
Frequently asked questions
What is an inbox placement test?
You send a test email from your own mailbox to seed addresses we provide. SuperSend checks where your message landed—inbox, spam, or not received—across providers so you know how your sending path performs.
Why do I paste a tracking token in the email body?
The token ties your message to this test so SuperSend can match results to your specific send. You can hide it at the very bottom of your email—white text on white background works fine.
How long do results take?
Seed checks can take from a few minutes to several hours depending on provider load. Leave the results page open or bookmark it and come back later.
