A task can be finished in your head while still appearing open to everyone else. The final file exists, but the requester does not know which version to use or whether anything remains unresolved. A short closing message removes that uncertainty.
State what is ready
Name the requested output and link to its agreed location. If several drafts exist, identify the final version plainly. Avoid making the recipient search a long message history to discover which attachment supersedes the others.
Mention any limitation that affects use. For example, a table may include the records received by a stated date while excluding two items still awaiting confirmation. Keep this specific; a vague “please check everything” does not explain what remains uncertain.
Separate completion from the next decision
Your part may be complete even when approval or another person’s action is still needed. State that distinction without claiming the entire process is finished. Name the next owner only when responsibility has been agreed.
Finally, update the shared tracker if the team uses one. The message, file location, and task status should tell the same story. Closing a task well is a small coordination habit: it lets other people use the result confidently and prevents completed work from generating avoidable follow-up questions.
