Why can't I send more contact requests?
If your Contact Request campaign is not sending to more contacts, it's possible that you've reached your limit of pending contact requests.
You can check this here:
If you are on Premium XING, the limit is usually 100 outgoing connection requests at once.
If you are on TalentManager, the limit is usually 500 outgoing connection requests at once.
How to fix this
Run "XING Cleaner" to delete some old connection requests - https://app.effixient.io/app/contact-requests
