The three checks
Who may send as you
A public list of the mail services allowed to send email for your domain. Missing or outdated, and receivers can't tell your mail from a stranger's.
A signature on every email
Each outgoing email gets a cryptographic signature proving it came from you and wasn't changed on the way. Many businesses have it available but never switched it on.
The rule for fakes
The instruction that tells Gmail and Outlook what to do with email that fails the first two checks. Most small businesses don't have one — which means fakes are delivered like real mail.
Why it matters
The common failure is quiet. A scammer sends your customers an invoice that looks like yours, with different bank details. Or your own invoices and quotes start landing in spam, and you find out weeks later, from a customer who never paid because they never saw it. Neither problem announces itself — the first sign is usually lost money. Working SPF, DKIM and DMARC records are what make the fake version fail and the real version arrive.
How DomainTend works
We check your domain's public records — SPF, DKIM and DMARC — on a regular schedule, the same way we'd check our own.
If something is missing or breaks, you hear it from a person. A short, plain-English note: what we found, why it matters, and a link to the free fix guide so you can handle it yourself if you'd like.
Don't want to touch DNS settings? That's fine — it's the part most owners would rather hand off. Reply to our email and we can do the fix for you.
How we check (our method, in the open)
Everything we report comes from public DNS records — your domain's published SPF, DKIM and DMARC entries. We do not scan your website, probe your servers, test your passwords, or need any access to your accounts. If we ever email you about your domain, you can re-check the exact same records yourself, free, in about a minute — our fix guide shows you where. We'd rather be easy to verify than impressive-sounding.
Who runs this
DomainTend is run by Clark Mason, an independent operator working under WedgeCraft Labs. There is no call center and no ticket queue: emails are written and answered by a person. If something we sent you looks wrong, reply and say so — corrections are welcome and acted on.

About our emails: if DomainTend contacted you, it's because your domain's public records showed a fixable problem. Every message comes from this domain, is signed with a real name, and carries a working opt-out — one click and you'll never hear from us again. We don't buy or sell email lists, and we don't run trackers on this site.
