I have three BU all using the same domain to send mails from.
But each BU has its own dedicated IP address.
BU1 - 10.0.0.1
BU2 - 10.0.0.2
BU3 - 10.0.0.3
Will they have a combined reputation (because of the shared domain), and will they influence each other?
Or is the reputation calculated completely separated because of the shared IP's?
If I want to separate the domain and the IP address, but keep the current IP addresses, do I have to redo the warm-up process?
BU1 - 10.0.0.1 - firstname.lastname@example.org
BU2 - 10.0.0.2 - email@example.com
BU3 - 10.0.0.3 - firstname.lastname@example.org
BU1 - 10.0.0.1 - email@example.com
BU2 - 10.0.0.2 - firstname.lastname@example.org
BU3 - 10.0.0.3 - email@example.com
Same IP addresses are used as in the current set-up, but now also with separated domains. Need to re-warmup?
