Why are my LinkedIn InMails failing to save with an "Unauthorized" error?

Context

When trying to add InMails to a sequence, you may encounter the following error message: "Failed to save sequence: Unauthorized". This prevents InMails from being used in your sequences.

Answer

This error typically occurs when no InMail credits have been allocated to your LinkedIn senders. To resolve this, you need to assign InMail credits to each sender. Follow these steps:

  1. Make sure you have active Sales Navigator licenses connected to your LinkedIn profiles.

  2. Navigate to your settings > Senders > LinkedIn.

  3. Find the relevant sender and click Edit.

  4. Add the desired number of InMail credits (e.g., 30) per sender.

  5. Save your changes.

Once InMail credits have been assigned to your senders, you will be able to add InMails to your sequences without encountering the error.
