October 2026
Changed
Sending domain limits per plan
Sending domainsBilling & credits
The number of sending domains a workspace can add now depends on its plan:
Plan Sending domains Pay as you go 3, or 25 after your first credit purchase Pro 100 Business 1,000 If a lifetime license is active on the workspace, the license tier’s domain limit applies instead of the plan limit. The limit is checked when you add a domain: the Domains page shows how many domains you use, and Create a domain returns
422when you’re at the limit. See Domain limits.

New
One-click DNS setup for Cloudflare
On a domain’s DNS Setup tab, Emailit detects Cloudflare nameservers and offers Set up with Cloudflare. Paste a Cloudflare API token with Zone Read and DNS Edit permissions for the zone, choose which optional records to add, and Emailit creates or updates the records and checks DNS again.
The token is stored encrypted so you can sync the records again later, and you can disconnect it at any time. An existing DMARC record isn’t changed. See Set up DNS with Cloudflare.
Changed
Domain usage badge and lasting domain approval
On Pay as you go, a new domain registered less than 30 days ago waits for approval from the Emailit team before it can send. Once a domain is approved, the approval stays: if its DNS records later fail a check, sending stops until you fix them, but the domain doesn’t need to be reviewed again.
The Domains page title shows a used/limit badge for your plan. See Domain verification.
Improved
Daily DNS checks for sending domains
If a verified domain’s SPF, DKIM or return-path record stops passing, Emailit marks the domain as not verified and emails the workspace owner, so you can fix the record before your sends fail.
Domain verification also compares the DKIM record’s
v,kandpvalues instead of the raw text, so extra spaces, quoting or a different tag order no longer cause a failure. See Domain verification.Changed
Tracking requires a custom tracking domain

To track opens and clicks, publish a CNAME record from
go.yourdomain.com(or your custom tracking subdomain) togo.emailitmail.comand verify it. The Track loads and Track clicks switches on a domain turn on only after the record is verified.Links and open pixels in emails you sent earlier with shared tracking links keep working. See Custom tracking domain.
