Ramp is the finance automation platform helping businesses manage corporate cards, expense management, bill pay, and accounting integrations in one place. With a customer base spanning high-growth startups to large enterprises, Ramp operates a significant outbound sales motion — an SDR team generating pipeline across multiple verticals and buyer segments.
At Ramp's sending volume, email infrastructure isn't optional. Sequences, follow-ups, pre-call touchpoints — thousands of emails go out every day across dozens of active domains. When that infrastructure is healthy, the team performs. When it isn't, the damage is quiet, gradual, and easy to misread as a sales problem.
Ramp's outbound motion was growing fast — intentionally. Sales leadership was investing in headcount, expanding the SDR team, and pushing volume up to match the company's growth trajectory. On paper, everything was moving in the right direction.
But inbox placement was quietly deteriorating. The more the team scaled, the worse it got.
The core issue: Ramp had no dedicated deliverability infrastructure in place. As new reps came on and sending volume climbed, there was nothing managing domain reputation, pacing volume intelligently across mailbox providers, or monitoring sender health in real time. Domains accumulated reputation damage with every wave of high-volume sending. Inbox placement dropped. Emails that should have landed in primary inboxes were getting filtered — and reply rates fell with them.
The most costly part wasn't the drop itself. It was the disconnect between what the team assumed was happening and what was actually happening. Reps were sending. Sequences were running. But a growing share of that outreach was never being seen. Meetings that should have been booked weren't. Pipeline that should have been generated wasn't.
Headcount had scaled. Deliverability hadn't. And the gap between the two was quietly eating the team's output.
Ramp brought Maxify in to own the deliverability layer entirely.
The first thing we did was put every sending domain — existing ones included — through a proper warmup process. Maxify warmed each domain using the actual copy from Ramp's live sequences, so the content mailbox providers were seeing during warmup matched exactly what reps would be sending in production. This meant reputation was being built on content that reflected real sending behavior, not boilerplate emails.
Warmup volume was also dynamically weighted based on where each domain was weakest. If Google deliverability was underperforming, warmup activity shifted toward Google inboxes. If Microsoft was the problem, the weighting shifted there. At any given time, effort was concentrated on whichever provider needed the most attention — rather than spreading evenly across providers regardless of where the gaps actually were.
On the rep side, Maxify monitored the deliverability health of every individual sending address in real time. The moment any address dropped below a healthy threshold, it was automatically replaced with a warmed, healthy address — in the background, without any disruption to the rep's workflow. Reps never had to think about it. They kept sending. Maxify kept the addresses they were sending from in good standing.
The whole system ran silently underneath everything Ramp's team was already doing. Same sequences. Same cadences. Same tools. What changed was the foundation — and the foundation changed everything.
Inbox placement improved 67%. Emails that had been getting filtered started landing in primary inboxes — and prospects were actually seeing them.
Open rates increased 41%. Not because anything about the outreach had changed, but because the emails were now reaching the people they were sent to.
Reply rates increased 34%. The same sequences that had been underperforming started generating real responses again.
Meetings booked per rep climbed 28%. For a team that had been adding headcount without seeing proportional pipeline returns, this was the number that mattered most: individual rep output was back up, and the link between effort and results was restored.
Domain health scores held steady across all active addresses as volume continued to grow — because the moment any address showed signs of weakness, it was replaced before the problem could affect results.
