Doptar™ Deliverability Doctor

Bulk domain check

Paste your client domains and get one ranked table — the worst-configured domains first, so you know which to fix first. Checks public DNS for SPF, DMARC and MX gaps across every domain. (For a per-selector DKIM check, use the single-domain report.)

One per line, or separated by commas or spaces. Up to 25 domains at a time.

Public DNS only. No CRM login, no emails sent, no DNS changes — recommendations only.
