We have a pool of hundreds of proxy IPs that keep getting rotated automatically and proactively based on numerous different metrics (the total volume associated with each proxy, such as how frequently they were used, the reputation of the associated sending accounts, etc.).

That provides the best balance of keeping the high-reputation IPs in the pool and removing the off-balanced ones before they create any issues. They rely on two mechanisms - actively keep rotating IPs or they remove an IP after it has gotten blacklisted...

the problem with actively rotating IPs (the standard practice out there) is that you lose the good reputation ones and if you remove the IP after it’s blacklisted then it has already done damage.

other cold email tools out there only have a handful of IPs, don't monitor blacklists, don't rotate IPs, are all STATIC etc. It is not offered by anyone else on the market besides Instantly.ai.

If you are going to use Instantly from different places, then it's not going to make a difference where you use it from, because it's not your changing IP addresses that are going to directly interact with their mail servers - it's our rotating IPs that are going to do that. So it really doesn't make a difference if your location is changing.
