Email deliverability audit
Find every hole in your
email setup. Before Gmail does.
Paste your domain and get a 20-section audit covering DMARC, SPF, DKIM, MX records, and 50+ real-time blacklist checks. AI-written report delivered to your inbox in 2 hours.
DMARC
Policy strength, reporting setup, pct enforcement. We check if your domain can be spoofed — and give you the exact fix.
70% of domains fail this
SPF
Record presence, -all vs ~all vs +all, DNS lookup count (RFC 7208 allows 10 max). A +all record is an open invitation to spammers.
-all vs ~all matters
DKIM
We probe 20 common selectors (default, google, k1, mail, sendgrid, ses…) and flag weak key lengths. 2048-bit minimum in 2024.
key length critical
MX Records
Provider identification, redundancy check, PTR (reverse DNS) for each MX IP. Missing PTR = instant spam folder at Yahoo/Outlook.
PTR often missing
Blacklist Check
Real-time lookup against 50+ major RBLs: Spamhaus, SpamCop, Barracuda, SORBS, and more. Includes delisting steps for any listed IPs.
50+ RBLs in real time

Weighted A–F grade with industry benchmarks. 30-day fix plan ranked by impact/effort. Re-audit recommended after you implement fixes.

FAQ
What exactly do you check?
DMARC record presence, policy, pct, and reporting setup. SPF record presence, -all/-~all/+all qualifier, DNS lookup count. DKIM keys across 20 common selectors. MX records, PTR/rDNS for all MX IPs. Real-time blacklist status on 50+ major RBLs including Spamhaus, SpamCop, Barracuda, SORBS, and more.
When will I get the report?
Within 2 hours of payment, usually faster. The DNS checks complete in under 60 seconds; the AI report generation takes a few minutes. You'll receive a detailed HTML email at the address you provide.
What if my audit fails or I don't receive it?
Email support@voiddo.com with your domain. We'll re-run manually and deliver within 24 hours. Full refund if we can't deliver.
Do I need to add any DNS records or give you access?
No access needed. All checks are public DNS queries — the same checks that receiving mail servers perform on every email you send. Zero risk to your setup.
Does this work for subdomains?
Yes — enter any domain or subdomain. DMARC is checked at
_dmarc.yourdomain.com, SPF on the root domain, DKIM on the queried domain.Why $49 and not a free tool?
Free tools give you a grade and a list of issues. This gives you a 20-section AI-written report with exact fix steps, risk matrix, industry benchmarks, 30-day action plan, and ESP recommendations — the analysis that normally takes a consultant 4 hours to write.
