Why are my LinkedIn connection request messages not being sent?

Last updated: October 16, 2026

Context

When running a sequence in Topo with message in the Linkedin connection request, you may notice that only the first few connection requests are sent with a personalized message, while the remaining ones are sent as bare connection requests with no message attached.

Answer

LinkedIn connection request notes have a 200-character limit. If you use variables in your note, be aware that they count toward this limit and their length can vary significantly depending on the content they resolve to (e.g., a prospect's company name or job title).

If a note exceeds 200 characters, Topo will automatically send the connection request without the note rather than failing or stopping the sequence. This behavior is enforced by LinkedIn, not Topo.

LinkedIn also limits how many connection requests can include a note per week. This cap is lower on free LinkedIn accounts compared to Sales Navigator accounts. When this cap is reached, Topo will again send the connection request without a note instead of halting the sequence.

To avoid hitting this limit, consider the following:

  1. Upgrade to a LinkedIn premium plan or Sales Navigator, which provides a higher invitation message allowance (outside of Topo).

  2. Monitor your LinkedIn invitation message usage to avoid reaching the cap mid-sequence.

  3. Skip the message in the LinkedIn connection request.

Recommended Approach for Messaging

To avoid character limit issues and ensure all prospects receive your message, the recommended approach is to:

  1. Send the connection request without a note.

  2. Add a separate LinkedIn message step later in the sequence.

This ensures you have enough characters for your full message and that all prospects receive it, regardless of LinkedIn's note limits.
