GI email trap

Cleaning GI data is a big problem, and I usually go through MX records in batches and remove lines that contain google/outlook. But How to remove email traps?
So many so-called "anti-spam" organizations set up countless email traps and then blackmail mailers
The common practice for big mailers seems to be "If there are fewer than 500 mailboxes for the same domain, then it's most likely a trap for me, and I'll delete those domains." ???
Any suggestions are welcome, thanks

Lots of different ways...
1. Only mail to people that reply, spamtraps dont usually reply.
2. Look for opener/clicker automation, for example send 3 times and every time they open within the first minute or something of receiving the email.
3. Get ips ranges of major security companies and block them
4. Get blocked or abuse list of networks and reversed engineer the mx and block them too
5. Dont send to service emails.. info/customer/support/abuse etc
thats just a few off but there are many more ways.

To avoid traps, you should use real-time verification tools like ZeroBounce or NeverBounce. They detect "honeypots" better than manual MX filtering. Also, segmenting your lists by engagement helps keep traps away.

U can use millionverifier example
