Authenticated domains,
without the guesswork.
Deliverability starts with a properly authenticated domain. Zerokit walks you through DKIM, SPF and DMARC and tells you the moment it's right.
The whole authentication story, handled.
No more deciphering DNS docs at 2am - add a domain, paste the records, watch them verify.
Guided DNS setup
Add a domain and we generate the exact DKIM, SPF and DMARC records to paste into your DNS - copy, paste, verify.
DKIM signing
Every message is signed with your domain's key so mailbox providers can verify it's really you.
Custom MAIL FROM
Align the envelope sender with your own domain for stronger SPF alignment and cleaner headers.
DMARC ready
Publish a DMARC policy with confidence - alignment is handled, and reports show you what's passing.
Branded tracking subdomain
Click and open tracking run on your own subdomain, not a shared one, so links look like they belong to you.
Verification status
Watch each record flip to verified in the dashboard, and get told precisely what's missing if it doesn't.
