SPF check (Sender Policy Framework)

SPF declares which servers can send email for your domain. Bad SPF setup increases spoofing risk and can weaken deliverability when paired with weak DKIM or DMARC alignment.

• Free scan to confirm whether the record exists, is duplicated, or is close to the 10-lookup SPF limit.
• Paid report when you need a prioritized plan instead of guessing which include or sender to keep.

If you want to test a domain live, the scan stays on the homepage. This page is here to explain what SPF problems usually mean in practice.

What the SPF report looks like

Real technical checks

That matters because SPF is often not “missing”, it is just messy: too many includes, legacy senders, or conflicting records.

• The free scan surfaces the issue.
• The PDF explains what to keep, what to remove and what sequence is safer.
• That is the difference between a diagnostic and an actionable deliverability task.

Common SPF failures

No SPF record

Receiving servers cannot validate your sending sources.

Too many DNS lookups

SPF has a maximum of 10 lookups. Exceeding that can produce permerror.

Multiple SPF TXT entries

You should publish one SPF record only.

Weak policy ending

Choose ~all or -all based on your sender inventory confidence.

How SPF affects business email

Without a clean SPF setup

Teams accumulate old tools in DNS, hit lookup limits, and lose confidence about which platforms are allowed to send. That makes every DNS edit feel risky.

With a clear SPF action plan

You can simplify the record, keep only legitimate senders, reduce spoofing surface and support stronger DMARC decisions later.

FAQ

Do I need SPF if I do not send many emails?
Yes. It helps block spoofing and supports DMARC.

Can SPF alone fix spam placement?
No. DKIM, DMARC alignment, sender reputation and content still matter.
