Check the campaign's saved state and recipient results, not only the launch button. Launch still depends on an eligible sender, connection, funding, current access, and recipient safeguards. A saved campaign is different from a running one.
Read the specific refusal or pending reason before launching again. Confirm that the intended sender is connected and the correct team has the required credit. If a launch was accepted but no work appears, report the campaign reference, launch time, and displayed state. Do not bypass opt-outs or duplicate the campaign to work around an unclear result.
