A lot of our customers claimed they got this popup every week after about 100 invites. According to many LinkedIn-related websites, as well as LinkedIn support representatives, a new limitation will soon be placed on every profile in LinkedIn, capping the invitations to about 100 per week - Invitation Limit Reached - LinkedIn

Currently, not every LinkedIn account is under the limit since some of them can still send more invitations. However, it seems that LinkedIn is testing new limits on the part of its users, and this is a matter of time when they are implemented for everyone.

There is nothing to worry about as this is not a warning or a restriction that may lead to an account ban. LinkedIn has always been fighting against platform abusers, so this is just another attempt to protect its users from spam and maintain its reputation as a professional platform.

In this case, if you hit the limit, the only thing to do is to wait till the next week as it is not possible to get more credits even if you have a paid subscription or you have withdrawn sent pending invitations or some of them were accepted.

We suggest as well, to reduce the number of daily invites per day to warm up your account once you are notified of the weekly limits.
