Has anyone else noticed cold email accounts burning significantly faster when targeting B2B SaaS?
So I have been running cold email for a while now across a few different niches and I want to get other people's opinions on something because I keep running into the same pattern and I cannot fully explain it.
Here is what I keep seeing.
When I run cold email campaigns targeting dealerships, real estate, professional services, financial services type audiences, the accounts generally hold up for a month or more. Warmup is solid, sending volume is conservative, around 20 per day per mailbox, infrastructure is set up properly. Everything runs fine.
The moment I target B2B SaaS, the accounts burn in about six days. Every time. Same infrastructure, same warmup process, same sending volume. It does not matter.
I have compared the data across campaigns and the only consistent variable that changes is the niche. Everything else stays the same.
My current thinking is that it is an external issue rather than internal. Meaning the problem is not something I am doing wrong in my setup, it is the recipient behavior in the SaaS space specifically. SaaS founders and growth leads are the most saturated audience in cold email. They receive dozens of these a week, they know exactly what they are looking at, and I think they are hitting report spam at a much higher rate than people in other industries. That complaint rate builds fast enough to tip the account reputation inside Google's assessment window, which seems to land around day five to eight.
The other thing I think about is that a lot of SaaS companies run on Google Workspace with security tools that pre scan every inbound email. That could be compounding it.
But I want to be honest, I am not 100% certain this is purely external. There could be something about targeting this niche specifically, the type of copy needed, the offer type, that is amplifying the issue.
Has anyone else seen this? Is B2B SaaS just a graveyard for cold email accounts compared to other niches? Or have you found ways to make it work without burning through domains every week?
Genuinely curious what other people's data looks like on this.
