Hello Darren, sorry to cause a misleading information. That is usually done on my end. My concern if the sent delivery might not be attached to the campaign, it could lead to removing the sent delivery once we removed the workflow.

Hello Darren and ParthaSarathy, thank you for your prompt response. Does it mean the delivery should be attached to the campaign? I couldn't find the deliveries and I assume that I ididn't attach the deliveries to the campaign.

Hello, I may have accidentally deleted a workflow. Is there any way to retrieve the workflow? It contains deliveries information.  Another question, if we remove the workflow, do the deliveries will be removed too? Thank you.
