Every LinkedIn Recruiter license comes with an allotted number of InMail credits each month, which varies by the type of Recruiter account you have. Your team will receive a new allotment of InMail credits once a month starting on the date your account was created.
On the date your InMail credits refresh, you will receive your monthly allotment, and unused InMail credits from the previous month will roll over. However, any credits that would cause the total to exceed the account cap of four times your monthly recruiter allotment do not roll over and will expire. The total allotment of InMail credits you currently have will include any credits back from InMail responses and your monthly recruiter-type allotment.
Important to know
Every InMail message that is accepted, declined, or responded to directly within 90 days of it being sent is credited back. A pending InMail message isn’t counted as either accepted or declined. As part of the LinkedIn messaging experience, Quick Replies to InMail messages also count as a response.
