Took our deliverability problem off our plate and stuck around for the iteration
SmarterOutbound rescued our sending reputation in three weeks and then stayed in the iteration phase with us until the campaign was actually dialed in. Most agencies would have bailed at month two.
- Deliverability rescue was the strongest part of the engagement — sender reputation restored in under three weeks.
- Our HR tech ICP was narrower than their default playbook; first month of meeting bookings had quality issues.
- The team iterated with us through months 2-3 until 70%+ of meetings were genuine ICP fit.
- Most agencies would have argued and stalled. They iterated and fixed it.
I want to write a balanced review because most of what I see online is either glowing or savage, and the truth here is more interesting than either.
Where they delivered immediately
Our sending reputation was a disaster when we started. We had been blacklisted on two RBLs and our SDR team was getting 80%+ spam-folder placement. SmarterOutbound’s deliverability team rebuilt our setup — new domains, properly configured DMARC, dedicated IPs, IP warm-up — and we were back to inboxing in about three weeks.
That part alone was worth the engagement fee. If we had hired them only for deliverability work, this would still be a five-star review.
Where the iteration was needed
The ongoing campaign work was inconsistent in the first six weeks. We are an HR tech company selling to People Operations leaders at mid-market companies — specifically those with 200-1,000 employees who are replacing legacy HRIS platforms.
The first round of meetings they booked included a 12-person startup with no HRIS at all and a Fortune 500 already locked into Workday. About half of the early meetings had this kind of quality issue.
Here is the thing that earned the five stars: when we raised it, they did not get defensive. They asked for sample call notes. They added new disqualification filters in their human reply triage layer. They re-cut the ICP definition. By month three, around 70% of booked meetings were genuine ICP fit. By month four, it was closer to 85%.
Why this is rare
Most agencies would have argued that the meetings were “qualified by their definition” and pushed back on our feedback. We have hired four agencies before this one. The willingness to iterate inside the engagement — rather than treating the initial brief as set in stone — is the thing that separates the few good ones from the many mediocre ones.
The technical work was already great. The iteration culture is what made it a five-star engagement.
Recommendation
If you have a non-default ICP or a specific buyer profile that requires careful filtering, ask in the discovery call how they handle iteration mid-engagement. SmarterOutbound’s answer was the right one and they delivered on it.
