Cold email, one year on: it got bigger, not better
A year ago, we called out cold email for what it is: spam. We also warned that the ecosystem enabling it would keep on growing, just as long as it stayed profitable - from scrapers, to warmup tools, to disposable domains. Twelve months on, it’s time to take a look at the situation today, how the industry has responded… and what we’ve done about a large part of it.
New Feature | Spamhaus Reputation Checker: Troubleshoot your listing
It’s not always immediately clear why your IP has been listed or how to fix it. To help, we’ve added a new “troubleshooting” step to the IP & Domain Reputation Checker, specifically for those whose IPs have been listed on the Combined Spam Sources (CSS) Blocklist - IPs associated with low-reputation email. Learn how you can diagnose the issue using this new feature.
