LinkedIn sets a limit of 100 connection requests per week.

If you have a warm-up period turned on in the settings, we’ll be gradually increasing the amount of sent requests to imitate human behavior. For example, for the first week, we'll be sending 3-5 requests per day, 8-11 for the second, and so on. It's highly recommended to use the warm-up for fresh accounts or if you didn't send many requests before.

You can turn off the warm-up feature and set your own limits, but LinkedIn might block your account because of the rapid spike of sent requests, so be careful with that.

Where to find the feature in our app:
