I am currently using 'Cold Emailing' service which it requires to use the Domain that's is not directly used for your Main Business, for example, if main website is 'ABC.com', the cold email accounts(sender's) will be 'theABC.com', etc. and it requires to run 5~14 different series of Domain Names in the "Warm-up Pool" so that when is 'Black-listed' they change to new Domain Name.

The question I have is,
Q1. when using your 'EMail Campaign', can I use different Domain Name than my Main Website Domain? if one is Black-listed, can I switch to different domain?

Q. can I add multiple-domain names so that your 'Email Campaign' can use different domain when sending bulk Cold-Emailing?

Thank you!
