I'm not on the sending side, but I will note there are several ESPs running out of EC2. Some seem to use their own IP ranges, some do not.
I think if you're coming from an IP range you don't have direct control over (i.e., cloud space), you must take extra precaution to warm the IPs ( and domains, and click-track URLs, and and and ..). Understand you're going to have garbage neighbors (if you don't bring your own ranges), and understand the implications of that. -- Alex Brotman Sr. Engineer, Anti-Abuse & Messaging Policy Comcast > -----Original Message----- > From: mailop <mailop-boun...@mailop.org> On Behalf Of Al Iverson via mailop > Sent: Tuesday, March 26, 2024 11:44 AM > To: mailop@mailop.org > Subject: [EXTERNAL] Re: [mailop] is warming IPs still necessary? > > +1 to what Laura says. > > I run a couple of EC2-hosted mail servers .... but I smarthost their mail out > through another server, because, if you can get Amazon to unblock port 25 for > you, people are still probably going to reject your mail far and wide.
