Overview
You may see a "LinkedIn InMail limit reached" warning on your sender profile even when your Sales Navigator still shows available InMail credits. This is a new behavior LinkedIn has introduced recently and is not related to the credit balance in your Sales Navigator.
LinkedIn uses two separate limit systems
The credits visible in Sales Navigator are only one of the two mechanisms LinkedIn uses to control InMail sending:
Monthly credit balance — the "purchasable" InMail credits visible in your Sales Navigator UI. These reset each billing month.
Velocity-based rate limiting — an invisible limit LinkedIn applies based on how fast you're sending InMails, regardless of your credit balance.
Even if you have plenty of unused credits, LinkedIn can temporarily block InMail sending if it detects that your sending velocity has significantly accelerated compared to previous weeks.
Important: This velocity-based limit is not set by GetSales. It is enforced by LinkedIn's anti-spam algorithms and applies to your LinkedIn account regardless of which tool you use.
How it looks in practice
Here's a real example of how the velocity limit gets triggered:
A sender sent 72 InMails across 23 days (mid-March to early April) — averaging ~3 InMails per day.
Then the same sender sent 115 InMails in the next 7 days — averaging ~16 InMails per day.
The sending velocity more than quintupled, so LinkedIn flagged the acceleration and blocked further InMails.
The sender still had 31 InMail credits available in Sales Navigator — but they couldn't be used until the limit was lifted.
How to avoid the velocity-based limit
To stay within LinkedIn's velocity thresholds:
Keep your daily InMail pace consistent. Sudden increases in sending volume are the main trigger.
Reduce the daily InMail limit in GetSales. If you're currently sending 25+ per day and getting limit warnings, try dropping it to 10–12 per day.
Increase volume gradually. If you want to scale up, do it over weeks rather than days.
Tip: You can adjust the InMail daily limit in the sender profile settings. A lower, stable pace typically produces a higher total monthly volume than aggressive sending followed by a multi-day block.
How GetSales handles the limit
When LinkedIn returns a limit alert to GetSales, the system:
Registers an InMail strike for the sender
Pauses InMail sending on that sender for a few hours (
hold_tillis set automatically)Runs automatic checks every few hours and resumes InMail sending once the limit is lifted
You don't need to do anything manually — the system will resume sending automatically once LinkedIn allows it. However, if the pattern continues, reducing the daily pace is the most reliable way to prevent the issue from recurring.
