If the IP addresses get associated with to many spam reports, unsubscribes etc the gmail etc will start to associate these IP addresses as bad, and will be more likely to just block them no matter what the content.
- gsich 8y agoDon't host emails where the IPs used have a high chance that they have been used before. So no AWS/Azure/xyz stuff.
- sudosteph 8y agoThere are actually 3rd party services that mail companies can use to check how trusted an IP is. So a lot of times, they'll provision an EIP on AWS, run a check against that service, use it if it's clean, and release and try again if it's not. It does lock you to using EIPs though, which makes it a bit harder to scale up.
- Scoundreller 8y agoWhat's an EIP?
- jffry 8y agoElastic IP. You can reserve EIPs from among Amazon's pool and allocate them to other AWS resources that need public-facing IPs (like an EC2 machine).
