If your emails are landing in spam, arriving late, or quietly disappearing, the problem is rarely the message itself. It’s how receiving servers like Gmail, Microsoft 365, and Yahoo read and trust your domain. When those trust signals don’t add up, even a legitimate, well-written email gets filtered, and usually with no bounce, no error, and no warning.
I diagnose and fix that. Not by setting a few DNS records and hoping, but by tracing your entire sending path the way the receiving providers actually evaluate it, then verifying with real inbox tests that mail lands where it should.
Deliverability comes down to trust, and trust is assembled from a handful of signals that a receiving server checks in the half-second before it decides where your mail goes. Is the domain properly authenticated, with SPF, DKIM, and DMARC all present and aligned, not just present? Does the sending pattern look like a real business or like something automated and disposable? Does the domain or its sending IP carry a damaged reputation from a past compromise or a list it shouldn’t be on? Is the mail provider configured the way that provider expects?
If even one of these is slightly off, the message gets downgraded, and the failure mode is often invisible. The most frustrating cases I see aren’t mail landing in junk; they’re mail being silently dropped before it ever reaches a folder. Microsoft in particular will accept a message, return no error to the sender, and then quietly filter it, frequently over something as small as a tracking link or an embedded image the filter reads as a phishing signal. To the sender, everything looks fine. To the recipient, the email never existed. That gap is exactly why deliverability problems get misdiagnosed for months.
I treat deliverability as a forensic problem, not a checklist. Anyone can publish an SPF record; the question is whether it passes, whether DKIM signs and aligns, whether DMARC is enforcing or just observing, and whether all three agree on the same domain. I work through the full path: DNS configuration, provider setup, authentication results, reputation, and the headers of mail as it’s actually received. Then I confirm fixes against live inbox placement at the major providers rather than declaring victory at the DNS level.
When something is being filtered, I’d rather find the specific cause than apply a generic “best practice” and move on. Sometimes that’s a bloated SPF record blowing past the ten-lookup limit. Sometimes it’s a misaligned DKIM signature. Sometimes, as in the silent-filtering case above, it’s content in the message itself tripping a provider’s classifier. The cause dictates the fix.
Most clients fit one of two engagements, and if you’re not sure which, I’ll tell you after a look at your setup.
Authentication Setup: a one-time fix. This is for businesses that have never properly configured email authentication, or that recently changed providers or domains and want their foundation correct and verified. I audit your current authentication, configure SPF cleanly (no guesswork, no bloat), set up and validate DKIM, create and align a DMARC policy, and confirm that mail passes authentication across Google, Microsoft, and Yahoo. You finish with a domain that is correctly authenticated and trusted at the technical level.
Full Deliverability Package: authentication, reputation, and monitoring. This is for businesses actively landing in spam, warming up a new domain or sender, recovering from deliverability damage, or simply depending on email for revenue and operations. It includes everything in the Authentication Setup, plus sending-path analysis across providers, a reputation and filtering assessment, real inbox-placement testing, a warm-up strategy where one’s needed, ongoing monitoring, and plain-English reporting on what’s improving and why. The outcome is a stable, trusted sending reputation and confidence that your mail is reaching real inboxes.
This work matters most when email is load-bearing for your business, especially when a missed invoice, confirmation, password reset, or client message costs you time, money, or trust. It’s a particularly good fit for professional services firms, SaaS and online platforms, membership sites, e-commerce and invoicing systems, and any organization recovering from a security or phishing incident where Google Workspace alert routing, email authentication, and account-access evidence all need a second look. That kind of cross-system review is what uncovered the root cause in this Google Ads MCC account-takeover investigation. If you’d rather have one person accountable for the outcome than collect trial-and-error advice from forums, that’s the engagement.
What it isn’t: this is not a bulk-email marketing service, a copywriting or campaign service, or a “set some records and disappear” job. It’s infrastructure-level deliverability work, done carefully and verified properly.
If you’re not sure which option fits, that’s normal. Most clients aren’t. Fill out the form below and I’ll review your setup, explain what’s happening in plain English, and recommend the right path forward.
