Add the ability to specify when to send the message to a specific person.

Example 1:
The lead sent you a message asking you to remind him about something next week or next month. You just create a message for that period with the reminder and forget about it. No need to create new tasks to do something. It saves time.

And also, be able to choose if to cancel message sending automatically in case the lead send you any new message after scheduling, or anyway send it on a schedule.

Example 2:

• Same situation as in Example 1, but the lead sends you a new message asking to have a meeting earlier; in this case, your "reminder" will be inappropriate. On the other hand, if the lead has a birthday, you schedule a birthday message with wishes. It doesn't matter if this person sends you other messages, it will be appropriate to send birthdays wishes.
