SPF lookup analyzer

SPF allows only 10 DNS lookups. Add Google, Microsoft, a CRM, and a help desk and you quietly blow past it — and every receiver starts treating your authentication as broken. This counts the real number, includes and all.

Free, no account. We resolve your live SPF record and every include: and redirect= beneath it to count the real number of DNS lookups.

Over the limit? Use the SPF record builder to consolidate your senders, or run a full email security scan to check SPF, DKIM, DMARC, and six more records at once.
