How a marketing agency stopped its quotes landing in spam
A 15 person marketing agency went from quotes vanishing into spam folders to email that passes authentication everywhere, found and fixed live on the call.
MStack360 fixed a marketing agency's email deliverability live on a call. Their sales quotes were silently landing in spam because the domain was missing correct SPF, DKIM, and DMARC records. We checked the domain live, set all three records for every sender, and tested email passing authentication before the call ended.
- Quotes now reach the inbox at Gmail, Outlook, and corporate filters instead of spam
- SPF, DKIM, and DMARC set correctly for every sender, including the printers, the CRM, and the newsletter tool
- The domain is protected against spoofing, so no one can easily impersonate the agency to its clients
Quotes were landing in spam, and nobody could see it
The agency was quietly losing deals to the spam folder. The cause had nothing to do with what the team wrote, and nobody had a way to see it.
Quotes went unanswered
Sent, then silence. Deals lost without a trace.
Lost to the spam folder
Prospects found them weeks late, if at all.
Nobody could see why
SPF, DKIM, and DMARC missing or broken.
A fee for nothing
A monthly charge suspected for free DNS records.
If your own quotes keep disappearing, our guide on why emails land in spam even when you think you are doing everything right explains what to check first.
A straight answer and a fix that covered everything
- A clear, honest answer on why their email was landing in spam
- SPF, DKIM, and DMARC set up correctly for everything that sends as their domain
- Coverage for the office printers, the CRM, and the newsletter tool, not just Microsoft 365
- Proof that mail now passes authentication, tested the same day
- Protection against criminals spoofing their domain to scam their own clients
- An end to any monthly email security fee they were paying for what are free DNS records
Fixed live on one call, with nothing left to chance
Live domain check on the call
We ran a check on their domain while they watched, and in about two minutes they could see the real status of their records. The missing and broken entries were right there on screen.
Mapped every sender
We listed everything that sends mail as their domain, including the printers, the CRM, and the newsletter tool. Overlooked senders are the usual reason these records break, so each one had to be accounted for.
Configured the records correctly
We set up SPF, DKIM, and DMARC properly for their full setup in DNS, and we touched nothing else.
Tested together
They sent a real email and we showed them, live, that it now passed authentication. No guessing, no waiting to find out later.
What the live domain check showed
We ran the agency's domain live on the call. Within about two minutes they could see the real status of every record. Once we set them correctly, all three were passing.

Email the agency can trust, sorted in one sitting
All three records set correctly
SPF, DKIM, and DMARC configured properly for the agency's real sending setup, done in DNS in a single sitting.
Every sender covered
The printers, the CRM, and the newsletter tool that send as the domain were all included, so nothing legitimate gets flagged.
Verified live and documented plainly
A test message sent and confirmed to pass before the call ended, plus a one page summary in plain English for their files.
Protected from spoofing
DMARC in place so criminals cannot easily impersonate the domain to scam the agency's own customers.
The payoff for the agency
"We had no idea how many deals we were losing to a spam folder. They showed us the problem live, fixed it in the same call, and we could actually watch our test email come through clean. It cost us a fraction of what we thought, and it ended a fee we should never have been paying."

What people ask about this kind of project
Aren't SPF, DKIM, and DMARC something I have to pay for monthly?
No. They are free DNS records. Many hosts and resellers bundle them into a paid email security package, but the records themselves cost nothing. If you are paying a monthly fee for this, we will often end it.
Will fixing these records break the email my printer, CRM, or newsletter tool sends?
Not when it is done right. We map every tool that sends as your domain first, then configure the records to cover all of them. Those overlooked senders are the usual reason these records break in the first place.
How quickly can you tell if my domain has a problem?
About two minutes. We run a live check on the call so you can see your domain's real status while you watch. Fixing what is missing or broken is often done in the same session, though more involved setups can take longer.
Does this also cover sending thousands of marketing emails at once?
We are honest about this. Microsoft 365 is built to keep you safe as a recipient and to send everyday business email reliably, not to blast thousands of marketing emails at once. For true bulk sending you want a dedicated email platform, and we will tell you so. This agency was sending normal business email like quotes, not bulk campaigns, so Microsoft 365 with the records set correctly was the right fit.
