InMail allocation allows LinkedIn Recruiter admins to set limits on the volume of InMail messages that can be sent by all of the seats on a contract. It also gives admins access to restrict the ability for all seats to send bulk InMail messages.
If your Recruiter admin has set InMail limits, you can monitor your monthly InMail usage and check when you have met your limit through the following ways:
If you haven't reached your InMail usage limit, you’ll see an InMail Credits counter at the top of your Compose Message side panel. The InMail Credits counter will show how many InMail credits you’ve sent out of the total available to you.
If you’ve reached your InMail usage limit, you’ll see a red warning message indicating Monthly InMail limit reached at the top of your Compose Message side panel.
