Stop bad emails before they hurt your business.

Verify emails from the jump to avoid dead leads, bounced campaigns, or junk signups. No salespeople. No BS.

Email address

Start now

🐌

Sending marketing emails is not like snail mail.

Email marketing campaigns are heavily regulated by mailbox providers like Google, Microsoft, and Yahoo. Your domain has a ‘sender reputation’—they’re keeping track of it.

⚖️

Who you shouldn’t email is as important as who you should.

Every email you send, impacts your sender reputation—ones that bounce, ding it. Too many dings, and mailbox providers will limit your ability to reach your audience.

👩🏻‍🏫

Reckon is the most important step you can take.

Our no-nonsense approach allows you to get email verification into your workflow quickly, so you can prevent dings to your sender reputation and reach your customers. In your deliverability journey, it’s a good start.
