Five questions before you trust us.

Will this break my email?

No. The fix is a DNS record that tells the world which servers are allowed to send mail as you. It can't stop legitimate email; it can only help your real mail get through and stop fake mail from passing.

Do I need to know what DMARC is?

No. DMARC is the technical name for the standard; you don't need to know how it works. We translate everything into plain English: who's sending mail as your domain, whether they're legitimate, and what to do about anything that isn't.

What if I have multiple domains? Can I upgrade later?

Yes. Starter covers 1, Pro covers 5, Team covers 25. Upgrade anytime from your account settings. The change takes effect immediately.

When does my card get charged?

Your 7-day trial requires no card. If you add a payment method during the trial, you're charged at the end of the trial. If you don't add a card, your account pauses (data preserved, resume any time).

Can I cancel anytime?

Yes. Month-to-month, no contract. Cancel from your settings; you keep access until the end of the current billing period.
