We have some questions here with the invoice we may get if we overcome the 45.000 contacts applicable in the Corporate licence.
The point is we are gonna import 40.000 contacts Manually (via import into Data Extension). And then, in the next month we will synchronize with Sales and some contacts will be duplicated in ALL CONTACTS because of different Contact Keys.
Is there any way to avoid this? Do the platform merge the contact in Sales with the one already in SFMC in order to avoid the duplication?
I have checked the link underneath, but still is not clear how this works
What are the usage charges in Marketing Cloud's pricing model?
Thanks a lot,
