Sound familiar?

Your emails go out. The replies don't come back.

  • You’re sending emails but getting no replies.
  • Clients tell you your email was sitting in their spam folder.
  • Gmail bounces your message with an error like 550 5.7.26 that nobody can explain.
  • Someone sent emails pretending to be your company.
  • Your email provider told you to “set up DMARC” and you don’t know where to start.

If you leave it

The rules changed. Most domains didn't.

Gmail can reject it

Gmail requires every sender to authenticate their domain. Mail that fails can be marked as spam or bounced. Gmail sender guidelines

Outlook can refuse it

Since May 5, 2025, Outlook.com rejects high-volume mail that fails these checks. Outlook postmaster

Anyone can send as you

Until your domain tells inboxes to block fakes, a stranger can send email that looks like it came from you.

One bad campaign hits everything

Cold email from your main domain shares its reputation with your invoices, proposals and client replies.

Questions

What does it cost?
$249 for one domain. $497 if you have up to 3 domains, or if the check shows SPF is missing, doubled or over its limit. Fixed price, no retainer.
How long does it take?
About 2 hours of your time. The full fix runs 30 to 45 days, because we only block fakes once reports show all your real email passing.
What access do you need?
A user login on your DNS provider, like Cloudflare or GoDaddy, or 20 minutes on a call while you paste the records. We never ask for passwords.
If my email health is fine, why no replies?
Then it’s usually who you’re emailing, what you say or the offer itself. Healthy email gets you a fair shot at the inbox, not a reply. The $1,250 Sprint plus sequence covers that side: a 4-step sequence written for your offer, a review of your list and a 30-day check-in on what to change.
Will this get my emails into the inbox?
Nobody can promise that, and you should be wary of anyone who does. This removes the technical reasons Gmail and Outlook filter or bounce your mail. Your list, your message and how much you send decide the rest.
I don’t send cold email. Do I need this?
If the check shows a problem, yes. Invoices, proposals and password resets face the same rules, and fixing it stops others sending as you.
Can I do it myself?
Yes. The free check gives you the exact records, and the free checklist covers the rest. We’re here if you’d rather not.
