Validate your SPF record, fix errors fast, and keep real mail landing in inboxes. Enter your domain to test your SPF setup and get clear, actionable guidance—built for Chicago SMBs

• Instant SPF validation — confirm your record exists and is syntactically correct before or after publishing.
• Readable results — see mechanisms/modifiers (include, a, mx, ip4, redirect, all) and what each means for your senders.
• Fix-first recommendations — tighten configuration without breaking legitimate traffic.

SPF tells receiving mail servers which hosts are allowed to send on your domain’s behalf—helping block spoofing and improve deliverability. It’s foundational and works best alongside DKIM and DMARC.

• Enter your domain (e.g., yourcompany.com).
• We fetch your SPF TXT record and validate syntax & structure.
• You get a plain-English report with issues, impact, and next steps.

• Required tags & order (starts with v=spf1, ends with all).
• Authorized sources: ip4/ip6, a, mx, include, exists.
• Modifiers: redirect, exp.
• Result semantics (Pass/Fail/Softfail/Neutral/PermError).

• Too many DNS lookups (10+): SPF must not require over 10 DNS lookups—exceeding this returns permerror and can break deliverability. We’ll help you reduce lookups safely.
• Multiple SPF records: only one SPF TXT record per domain; duplicates invalidate your policy.
• Risky/slow mechanisms: avoid ptr; it’s unreliable and discouraged by the spec.
• Overly broad “all”: using ~all/-all incorrectly can fail good mail—or let spoofers through. We’ll right-size enforcement with testing.

• Inventory senders (M365, Google Workspace, marketing, CRM) and authorize them explicitly.
• Stay under the 10-lookup ceiling (watch nested includes). Consider flattening with care to avoid staleness; managed approaches help.
• Pair with DKIM + DMARC for stronger protection and reporting.
