Our agency has had a name change, and I'd like to update our xxxx.createsend.com site address.
I just wanted to double check that this has no impact on an emails people already have, or the delivery of future ones - it's simply the address used for loggin in and account management?
Right, you can change your site address without breaking anything in previously sent emails, or future ones. The only exception is when you were using a custom domain. See http://help.campaignmonitor.com/topic.aspx?t=160 for more details on that case.
