SPF monitoring
How SealedMail checks your SPF record stays valid and within limits, and confirms your real senders are passing in practice.
SPF is the first check every receiving server runs on your email. Here is what SealedMail watches for your domain, what it means for your deliverability, and where it quietly breaks.
Watch: SPF in plain English
What SPF is
SPF (Sender Policy Framework) is a list, published in your DNS, of the servers allowed to send email for your domain. For the full breakdown, see our plain-English guide: What is SPF?
Why it matters to your business
It is the first thing receivers check. If your real email comes from a server that is not on your list, it looks suspicious; and if the list is broken, even legitimate email can fail to arrive.
How SealedMail monitors it
Every health check verifies your SPF record exists, is correctly formed, and stays within technical limits. Your weekly DMARC data then shows whether your real senders are actually passing SPF in practice.
What commonly goes wrong
The 10-DNS-lookup limit. Each third-party service you add (marketing platforms, CRMs, invoicing tools) consumes lookups, and once you exceed ten, SPF silently breaks for everything. It is one of the most common, and least noticed, email faults in small businesses.

Scope: reporting only
SealedMail monitors, interprets and reports. It does not change your DNS, configure your systems, or remediate problems. Your reports tell you clearly what is wrong and what kind of fix is needed, and the changes remain in your hands (or your IT provider’s). That boundary keeps the service simple, affordable and honest.
