The Problem
The Copy Was Fine.The Domain Wasn't.
David runs a recruiting agency that relies on cold email to reach passive candidates. The model is volume-dependent. When emails stop reaching inboxes, the whole pipeline seizes up.
His open rates were sitting in the single digits and reply rates were worse. He'd been sending from the same domain for over a year with no warmup process. The domain had quietly accumulated enough negative signals to push emails into spam.
His copy wasn't the problem. His domain reputation was.

After E-Warmup
The Fix Was Systematic
A year in, David's cold outreach runs the way it should have from the start. Open and reply rates more than doubled. The candidate pipeline is consistent and the team isn't losing placements to spam folders nobody checks.
The fix was systematic. Correct the authentication. Clear the blacklist history. Rebuild domain reputation properly. Then maintain it. All 3 blacklists cleared. Domain restored and reputation rebuilt within 10 days.
“I didn't know my domain had three blacklist entries until E-Warmup flagged them. I kept blaming the copy. Turns out the emails weren't even reaching the inbox. Within two months our reply rates more than doubled. A year later, the numbers are still holding.”

Our outbound emails were landing in spam without us realizing it! E-Warmup helped us fix inbox placement and stabilize sender reputation. We saw a 38% increase in open rates within two weeks.

Managing multiple client domains was always risky with deliverability. E-Warmup gave us visibility across everything. We've seen up to a 2.1x increase in reply rates on outbound campaigns.

We thought our issue was bad email copies. Turns out, emails weren't even reaching inboxes. E-Warmup fixed that, and reply rates increased by 44% in the first month.
