We stopped guessing why replies dried up. We got a plain-English plan, followed it, and our emails started landing again.

TL;DR

Example SaaS Co. sold to B2B teams through cold email. Over a few months, replies fell off a cliff and most emails were landing in spam. We audited their setup, rebuilt their sender reputation with a gradual warm-up, and set up monitoring so problems get caught early.

Objectives

Understand where their emails were really landing, and why
Recover their sender reputation without pausing outbound entirely
Put monitoring in place so the problem doesn't quietly come back

Strategy

1. Diagnose. We audited their sending setup and ran spam tests across the major email providers. The picture was clear: most of their emails were being filtered out at Gmail and Outlook.

2. Repair. We built a recovery plan in plain English, then ramped up sending gradually so email providers could see healthy, natural activity again. We also removed addresses that bounced or never engaged.

3. Protect. We set up continuous monitoring, with alerts and a recommended fix whenever something slipped.

Results

Inbox placement climbed from 31% to 94%, and the share of emails landing in spam fell from 58% to 4%. Reply rate rose from 0.8% to 3.9%, and the team was back to a healthy sending pattern in six weeks.

This is a sample case study showing what a real one will look like. The numbers are illustrative.
