No commitment. We'll show you exactly what's broken before you pay anything.

Usually replies in under 2 hours · always same business day

Illustrative. This is what we check, and fix.

Authentication you can guarantee. Inbox placement you can't fake. We're straight about the difference.
The situation

You already worked out it isn't the copy.

Reply rates fell off a cliff. Opens cratered. Or a tool told you flat out that you're in spam.

You're buying domains, warming them, burning through them, and doing it again next month because the last batch got cooked.

Someone told you to "just set up DMARC." You did, or your VA did, and nothing changed.

No technical person in the building. SPF, DKIM and DMARC are a black box you don't want to own.

Meanwhile every message sitting in a spam folder is pipeline you can feel slipping.

Why it's actually happening

The part nobody explains.

Most deliverability problems aren't your copy and they aren't your warmup. They're broken authentication. Your domain isn't proving to receivers that your mail is really yours, so the big providers quietly filter it for technical reasons that have nothing to do with what you wrote.

The usual culprit is alignment. You can have SPF, DKIM and DMARC all "set up" and still fail DMARC, because none of them line up with the address your recipient actually sees. Adding a DMARC record is not the same thing as DMARC working. That gap is where almost every broken setup lives, and it's invisible unless you know to look for it.

Then in 2024 the major providers tightened their sender rules. Setups that used to limp along now get blocked outright. A lot of senders got hit by that and never got told why.

Tools will flag the problem. They put a red mark next to your domain and leave you to figure out the rest. Flagging it and fixing it are different jobs. Fixing it is ours.

What we do

A productized, done-for-you fix.

  • 01We audit your current setup and find every place you actually send from. Primary mail, your marketing platform, your CRM, invoicing, support desk, the lot. Most companies send from more sources than they remember.
  • 02We fix SPF, DKIM, DMARC and alignment so every legitimate source authenticates and lines up with your From address.
  • 03We walk you to DMARC enforcement, the policy that actually stops spoofing and earns receiver trust, without breaking a single piece of your real mail.
  • 04We set up monitoring so you can see what's sending as you and catch problems before they cost you.

No black box handed back to you. You get a setup that works and a clear picture of why.

What we guarantee, and what we don't

The honest line, up front.

We guarantee your email is correctly authenticated. We don't promise the inbox, because no honest provider can.

Anyone who promises guaranteed inbox is selling you something. Whether your mail lands also depends on your sending reputation and how people engage with it, and a DNS record doesn't control that. What we do is strip out every authentication reason you're being filtered, then tell you straight which of your remaining problems are authentication (we fix those) and which are reputation (we tell you exactly what to do about them).

That line matters. It's the difference between someone who knows this work and someone reading you a script.

How it works

Four steps, built so nothing breaks.

Audit

We map your current authentication and every sending source, and show you what's actually broken.

Fix

We correct SPF, DKIM, DMARC and alignment across all of it.

Enforce safely

We start in monitor mode so nothing changes for your senders, then ramp the policy in stages, checking reports at each step.

Monitor

Ongoing visibility so it stays fixed and you see new problems early.

The word doing the heavy lifting there is "safely." We never flip a switch and hope.

Who this is for

You'll know if this is you.

Cold-outbound teams and founder-led sellers running email at volume, where deliverability is the revenue.

Lead-gen agencies managing outbound across multiple domains and inboxes.

Any high-volume sender sophisticated enough to know they have a deliverability problem but not technical enough to fix alignment.

B2B SaaS SDR teams and recruiters who live in the inbox.

Run a Shopify or Klaviyo store and your marketing or transactional email started hitting spam after the 2024 sender rules? This is for you too.

If you just want a magic "guaranteed inbox" button with no questions asked, we're probably not your people. We fix the foundation. We're honest about the rest.

Who's behind it
Ori, founder of the deliverability service, Amsterdam
Ori · based in Amsterdam

Hi, I'm Ori.

I'm building this service, and I'd rather you see who's behind it than hide behind a wall of logos.

I've spent fifteen-plus years in technical support and service operations at enterprise software companies. The kind of roles where DNS, email authentication and "why isn't this delivering" land on your desk and have to actually get solved. I've been the person customers were sold to, and the person delivering the fix afterward. So I know both sides of this. The technical reality of getting authentication right, and what it feels like to wonder whether you're being handled or just upsold.

Here's the honest part. I learned this the way I'll work on your setup, by doing it on my own domains first. Breaking the configuration on purpose, watching legitimate mail fail, and fixing it. Alignment failures, the SPF lookup limit, the sender-rule changes, the "I added DMARC and nothing happened" trap. Not theory. Reps.

I'm taking on a small number of founding clients while the service is new, which means more of my attention on your setup than you'd get later, and a straighter deal, because I'm building a reputation rather than coasting on one.

Questions

The things people ask first.

No. We start in monitor mode, which changes nothing for your senders, and only ramp enforcement in stages while watching the reports. If anything looked at risk, we'd catch it before it hit your real mail.

No, and you should be suspicious of anyone who does. We guarantee correct authentication, which removes every technical reason you're filtered. Inbox placement also depends on reputation and engagement, which we improve and advise on but won't pretend to control.

No. Warmup builds sending reputation. It doesn't authenticate your domain. If the foundation underneath is broken, you're paying to warm up mail that's getting filtered for technical reasons anyway. The authentication has to be right first.

You can. The records aren't secret. Most people don't because alignment is fiddly to diagnose, the sources are easy to miss, and rushing to enforcement before everything's aligned is exactly how you block your own legitimate mail. We've done the breaking-and-fixing so you don't have to learn it live on your own pipeline.

The audit is quick. The fix depends on how many sending sources you have and how your DNS is set up, and we'll tell you the timeline once we've seen it. Enforcement is then a staged ramp rather than a single day, by design, because that's what keeps it safe.

Yes. Teams running outbound across many domains and inboxes are exactly who this is built for.

Get started

You know it's broken. Let's show you exactly how, for free.

Tell me your domain and what you're seeing. I'll run the checks and send you a plain-English breakdown of what's broken, whether or not you hire me. You'll hear back from me, not a bot or a queue, usually within a couple of hours and always the same business day.

No commitment. I'll show you exactly what's broken before you pay anything.
