Through NIXZ, you can send a maximum of 30 LinkedIn messages per day per connected LinkedIn account.
This limit applies to all LinkedIn messages together. There is no difference between connection requests with a message and messages to existing connections. The type of LinkedIn account also does not change this limit: standard, Premium, Recruiter, and Sales Navigator all fall under the same daily maximum.
Once the daily limit has been reached, no additional LinkedIn messages are sent from that account on that day. Any following LinkedIn steps remain in the campaign and can be executed later according to the schedule.
