Doptar™ Deliverability Doctor

Bulk domain check

Paste your client domains and get one worst-first ranked table — the riskiest configurations first — then the priority fixes for each. Use this to build the Agency Deliverability Audit Pack. 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.

  1. 1
    client-domain-a.comNo DMARC; SPF fails
    At risk
  2. 2
    example.comDMARC p=none
    Needs work
  3. 3
    client-domain-b.comSPF, DMARC, MX OK
    Healthy
Illustrative example — a bulk check ranks your client domains worst-first.

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