The three levels
Selecting conversations gives you progressively wider scope, so it is worth knowing which one you are about to use.
Once a selection is active, apply the action, for example Mark as done.
Clearing a backlog safely
Before clearing everything, do one pass on what is bold. Bold means the guest sent the last message, so those are the conversations where somebody is genuinely still waiting. See Reading the conversation list. Nothing is destroyed by marking conversations done. They stay searchable in the Done tab, and any conversation where the contact replies comes straight back to To do.Frequently asked questions
Does marking conversations done delete anything?
Does marking conversations done delete anything?
No. Done is a status, not deletion. The full history stays intact and searchable.
