Delete a sent message

I need to remove a message I sent to Rashid in the customer support group that contains the wrong pricing. Delete my message for everyone in that chat today and confirm it no longer appears in the thread for any participant.

Before I delete the wrong pricing message for everyone, make it obvious what will be removed and when: show the exact message text, who will still see it if they’re offline, and any evidence the customer might have already screenshotted it so I can decide whether deletion is enough.

I deleted the pricing message to Rashid but I’m not sure if he already saw or copied it. He’s the procurement lead and replied minutes before I deleted. Tell me how likely he has the info, what to watch for in the chat to know if he saw it, and the best next step to fix exposure without escalating—should I send a corrected message, call him, or both?

Over the last month I’ve repeatedly posted prices without checking and then deleted the messages when a client reacted. That costs trust. Help me change one habit so this stops: what concrete pre-send check or quick delay should I adopt, and how do I introduce it to my small team so it becomes normal?
