Nothing…Way over my head.

hi there

can you past a copy of your campaign ( I am assuming you are trying to do this through a campaign?).

Do y ou maybe have a jump even inside the campaign?

How do I post a copy of a campaign here?

It doesn’t matter whether I’m using a campaign or the dashboard. Some contacts are not being moved to another segment, and some contacts can’t be removed from a segment that they’re already in.

This is an almost new installation, I only have 10 contacts.

You can do a screenshot.
May I ask if you added the contacts to the segment manually?

Also when looking at the campaign results what do you see?
