See where your email lands before you press send.
Send your email to seed accounts and find out where it lands: inbox, spam, or somewhere in between. SendKit shows you inbox rate, spam rate, and an overall score so you know if you're ready to launch.

Test placement before burning leads.
Know your inbox placement before your campaign goes live. Don't burn leads to find out you're in spam.
Inbox rate percentage, spam rate percentage, and overall score. Simple and actionable.
Follow your test from pending through sending and monitoring to completed. You always know where it stands.
Make changes to your email and run another test. Keep iterating until placement looks right.
Test first, send when you are ready.
Pick the email you want to test and kick off a placement test from your dashboard. SendKit sends it to seed accounts across major providers.
Your test moves from pending to sending to monitoring to completed. You can track its status the whole way through.
When the test completes, you get your inbox rate percentage, spam rate percentage, and an overall placement score.
Test every campaign before it goes live. Finding out you're landing in spam after 5,000 sends is expensive. Finding out before is free.
Swap your subject line or tweak your body copy and retest. See which changes move you from spam to inbox.
Finished warming up a new domain? Run a placement test to confirm you're actually hitting inbox before launching your first campaign.
Fix placement before it costs you leads.
Know your placement before you burn a single lead
Many cold email platforms don't offer inbox placement testing at all. You send your campaign and hope for the best. SendKit lets you test first, so you can fix issues when the cost is zero.
Fix placement problems before they cost you leads
Most teams discover they're landing in spam after a campaign has already gone out and the reply rates are terrible. By then, the damage is done and the leads are burned. Placement testing lets you catch and fix issues when the cost is zero: before a single campaign email is sent.
Clear results, not a wall of data
Inbox rate, spam rate, overall score. That's what you get. No need to interpret complicated charts or decode cryptic metrics. If your inbox rate is high and your spam rate is low, you're good to go. If not, tweak and retest.
Got questions? We've got answers.
SendKit sends your email to seed accounts across email providers. It then checks where each email landed and reports back with your inbox rate, spam rate, and overall placement score.
