Say which account.
If you manage more than one business or channel, identify the destination clearly. Ask your agent to confirm the connected accounts before it prepares a batch. An account name is more useful than “post this everywhere”.
Provide the actual content.
Attach the media you want to use, or give your agent an accessible source. Tell it whether the caption is final or a draft. Distinguish the content you have approved from ideas you are still exploring.
Include a time zone.
“Friday morning” means different things in different places. Include the date, time and intended time zone when the timing matters. Review the accepted schedule rather than assuming a conversational phrase was interpreted exactly as you intended.
Ask for a preview and a confirmation.
A useful workflow has a moment to review the post and a clear result after scheduling. Check the destination, content, caption and time. After publication, ask what went live and whether any channel needs attention.
