Case study: How we fix deliverability with clients. You can use it too if your placement tanks
Hey there. Want to share how we helped a small team define a problem in outbound and fix it.
Hope you'll find it useful.
An AI automation agency reached out to us to consult on their outbound GTM execution.
Their campaigns were full of the typical mistakes, but first their workflow looked like this:
- Started with 20K emails per month to find traction
- Got first sales, scaled the exact same campaign to 120K
- Never checked what IP model their provider gave them
Result? 120K emails with identical copy sent from SMTP inboxes on shared IPs.
Around 37% (44K emails) were landing in spam.
At typical benchmarks for their SMB automation niche - 3% reply rate with 25% positive - this was costing them $220K!! in retainer across clients.
What we've done (easy setup):
Identified urgency to start sending: the client said "as soon as possible" — we chose pre-warmed Outlook inboxes instead of running a 3-week warm-up process.
Set up DNS (SPF, DKIM, DMARC) properly:
- SPF - one record, never +all
Publish exactly one SPF record per domain. End it with ~all or -all, never +all (14% of errors). Keep DNS lookups under 10 and the record under 255 characters.
- DKIM - enable it and use the right selector
Enable DKIM signing (11% of domains don't have it at all) and verify the selector matches what their sending platform expects (4% of errors come from wrong selectors). Without DKIM, Outlook and Gmail can't validate that the message wasn't altered in transit.
- DMARC - published and progressing past p=none
Publish a DMARC record and move past p=none once SPF and DKIM are aligned and reporting clean (9% of domains stay stuck on p=none forever, which gives zero enforcement). Make sure the rua reporting address actually exists.
% of domains and mistakes is what we track and see over the last 7 months of building outbound campaigns.
Rewrite their copy following strict Outlook rules:
- No ESP matching
- No open tracking
- No links included in body copy (they trigger the Safe Links scanner_
- No dollar signs or financial language
- Max 70 words per email
- Spintax on every 2–3 words, especially in signatures
To not be unsubstantiated: 2 months in, and this agency books around 40 calls per week and scales by +50K inboxes every month.
They didn't change the offer or positioning, they just fixed infra and cut the copy down.
Did you notice any pattern that your outbound engine follows??
