3 checks a day, no account. Sequences, line edits, spam rules, and a one-off SPF, DKIM, DMARC, and MX lookup. Sign in if you want those checks kept in history.
Pro is $19/month
The free checker is enough to lint a few notes a day. Pro is for the person running the sequence: unlimited checks, a saved sending domain, and rewrite.
Pro
$19/month removes the daily cap, saves one sending domain, and keeps a timeline when SPF, DKIM, DMARC, or MX changes. The daily recheck runs when the host cron is configured.
Cancel when you want
Manage billing on the account page opens Stripe’s customer portal. When the subscription is canceled, the plan returns to Free. We store the customer id, not the card.
Useful for founders, SDRs, and agencies checking a sequence before it goes into Instantly, Smartlead, or Apollo, including drafts that came from a model.
