About automated emails

Hi

We use offline payments for our events.
We then send an automated email when a ticket purchase is made.

Once the participant has completed the payment,  we will change the status of the ticket to [MARK AS PAID] . Participants will receive the same automatic email as when they purchased the ticket.

How can I change the content of the email when a participant purchases a ticket and when the status is changed?

Regards.
