About Generator Labs
We monitor the parts of your infrastructure that fail quietly: the blacklist listing that stops your mail, and the certificate that expires on a Saturday night.
Started With
Blacklists in 2012
Generator Labs began as RBLTracker, a service that checked IP addresses and domains against real-time blocklists and sent an alert the moment one turned up. Most senders found out about a listing from bounced mail or an unhappy customer. We wanted them to hear it from us first.
Customers kept asking us to watch their certificates too. An expired certificate takes down a site or a mail server just as suddenly as a listing does, and usually at a worse hour. So we built Certificate Monitoring, renamed the company, and put every product under one account.
We're a remote-first team based in Canada. The people who build the platform are the same people who support it, so a question about a listing or a failed check reaches someone who knows the code.
