Why Combine DNS Audits & Bulk Verification?
Fixing SPF, DKIM, DMARC, and MX records protects your outbound domain authentication, while scrubbing your recipient list removes dead mailboxes, catch-all risks, and spam traps that trigger hard bounces and ESP account suspensions.
Keep Hard Bounce Rates Below 2%
Google Workspace, Microsoft 365, and Yahoo enforce strict sender thresholds. Verifying cold outreach and newsletter lists—including isolating catch-all domains without paying $800/100K—keeps your hard bounce rate safely below 2% and protects your sender reputation.
Up to 90% Cheaper List Hygiene
Legacy email verification tools charge $400 to $649 per 100,000 credits. MailVeri delivers 99%+ accuracy starting at $0.0002 per email ($59 per 100K / $299 per 1M non-expiring credits)—see how our rates compare against MillionVerifier, ZeroBounce & NeverBounce, DeBounce, Reoon, and EmailListVerify.
SPF Record & 10-Lookup Limit FAQs
Read DNS TXT & SPF Configuration Guide →What is the SPF 10-DNS-lookup limit?
RFC 7208 allows a maximum of 10 DNS lookups across include:, a, and mx mechanisms. Exceeding 10 lookups causes an automatic SPF PermError.
Can I publish multiple SPF TXT records on one domain?
No. Publishing more than one v=spf1 TXT record on the same hostname invalidates both records. Always merge all authorized senders into a single SPF record.
