How One Agency Recovered a Manufacturing Client from a 5% Open Rate Crash
The Challenge
An agency sending 200k emails/week for a US manufacturing client saw open rates plummet from 19% to 5%. Support tickets with their old provider (Pardot) said "everything looks fine," but revenue was tanking.
The Solution
They used VitaMail’s Deep Validator to scrub the entire client list, instantly identifying that 25% of their active contacts were actually hidden spam traps triggering strict enterprise filters. This revealed that the client wasn't suffering from bad copy, but from toxic data that was punishing their domain reputation.
The Result By immediately purging these risky addresses, the agency saw open rates rebound to 22% in just two weeks. This rapid turnaround allowed them to prove the crash was a technical fix rather than a strategy failure, effectively saving the client retainer and restoring the domain's health.
