Why can't I resume my campaign? (No prospects with LinkedIn URL)
If you click Resume or Start on a LinkedIn campaign and the action is blocked with a soft amber Alert that says 'No prospects with LinkedIn URL', this section explains why we block it instead of letting the campaign 'run' silently with nothing to send.
What the Alert means: your campaign has at least one active LinkedIn step (invite, message, InMail, profile view, or any wait or condition step), but none of your enrolled prospects have a usable LinkedIn identifier — no profile URL and no LinkedIn ID on file. LinkedIn steps have no way to identify a recipient without one, so the campaign would sit at 'running' while skipping every single prospect for the same reason. As of May 2 2026, we block Start and Resume up front with a clear amber Alert and an 'Import contacts' button.
What to do: (1) Click 'Import contacts' to open the campaign edit page. (2) Re-import your CSV — make sure your LinkedIn URL column is mapped to the LinkedIn URL field during the column-mapping step. Both standard profile links (linkedin.com/in/...) and Sales Navigator links (linkedin.com/sales/lead/...) are accepted; we resolve the latter for you. (3) Alternatively, if your prospects already exist in your workspace with LinkedIn URLs, edit the campaign's audience or prospect list to include them. (4) Click Resume again. The check passes and the campaign starts running.
If you start campaigns through the API: Start and Resume are refused while the audience has no LinkedIn-addressable prospects, with a clear reason in the response. Treat it as a permanent failure for the current campaign state — retrying without first importing prospects gives the same result.
Account safety: this is a read-only check against data we already hold — no extra LinkedIn calls, no rate-limit risk. It runs only when a campaign moves into the running state, so a campaign already running is never re-evaluated retroactively. Email-only campaigns are unaffected, since the check only applies when there is a LinkedIn step.
