Sending messages based on order time?

Question

WordPress

In general, the task is that, depending on the time and day, a person needs to send 1 out of 3 possible messages.
Before lunch (1st option) • Afternoon (2nd option) • At the weekend (3rd option)
How can you implement this method of sending a message after paying for the order?

Answer 1

Make a table,
id | message text | binding to order id | time of the planned dispatch | final dispatch time | send status | other data to send
put on a cron script that will check
the status of the send - not equal to sent
time of the planned send has already come.
You run this script every 1 minute, and it slowly makes a mailing list.
