Context

Your LinkedIn sender may occasionally show a status of "Invalid" in your Sender settings. This means the sender has lost its authenticated connection and will no longer track LinkedIn activity until it is repaired. Only senders with a "Valid" status are active and able to send.

Answer

A LinkedIn sender typically becomes invalid when the LinkedIn account password has been changed, or, less commonly, when LinkedIn disconnects the profile on its own. High sending volumes are generally not the cause — the platform caps activity at 30 messages per day per sender to keep usage safe.

To re-authenticate your LinkedIn sender, follow these steps:

1. Go to Settings → Senders and click the three dots next to the affected LinkedIn sender, then select Edit.

2. On the Sender Details page, under Providers, click Sign in with LinkedIn to re-authenticate, then click Save Changes.

3. If re-signing in does not resolve the issue, click Remove Sender to delete it, then re-add it under Settings → Sender Identity by connecting the LinkedIn sender again (via email + password or cookies) and saving.

Things to keep in mind:

• Make sure the sender is linked to the correct Sender Identity after reconnecting.

• If you are running LinkedIn outreach across multiple senders, spreading volume across more profiles is always beneficial.

• If disconnections happen repeatedly and you have not changed your password or are not using another tool on the same LinkedIn profile, please reach out to support so we can investigate further.
