How much mail are you sending in a single day? What kind of mail are you sending?
If it’s just B2B mail you are likely to not have a huge issue here. What I would recommend is moving a few domains over at a time and let them warm up the service. So day one move your two smallest by volume. Then the next day (or whatever makes sense operationally) move the next two. Then just work through transitioning the domains’ outbound servers across. Volumes less than about 10K a day don’t really need to go through a warmup process. Typically when we’re talking warmup, we’re talking about bulk mail and volumes in the hundreds of thousands. Some groups, IMO, take the warmup over the top. I’ve seen people try and ‘warmup’ for servers that are sending 5K a day over the course of 2 months. Many big senders will start their warmup at 10K a day. laura > On 7 Jul 2022, at 20:15, Russell Clemings via mailop <mailop@mailop.org> > wrote: > > Thanks, but the part I don't know is how to segment the outgoing mail.
