There are two ways to edit a scheduled message to a guest:
You can edit the messaging rule.
You can edit the scheduled message from the Activity log on the conversation thread or on the “Pending messages” tab on the Guest Experience page.
See more on the second item, here.
Editing messaging rules
This refers to editing the messaging rule in:
Hospitable > Guest Experience
Messaging rules
Any changes you make to a messaging rule under Guest Experience apply to all guests, not just some. Updates to the text, settings, or scope are saved automatically and will be applied to any existing unsent scheduled messages. These messages will still be sent, but they’ll reflect your updates.
If you adjust the rule’s scope to remove a platform or property, the rule will no longer apply to guests who booked through that platform or for that property. In this case, the prepared messages for those guests will be removed.
Note: The only caveat is if you had previously edited a scheduled message for a specific guest (this refers to edits made to a specific scheduled message, not the messaging rule), changes to the messaging rule will not affect that guest’s message—not even to remove it. More on this here.
Replies to events
Automatic messages that are generated by events such as new inquiry, new reservation and new cancellation will not be updated when you make any changes to the messaging rule, even if the message has not been sent yet (this means its Timing was set to either prepare for sending manually, or delay by an amount of time).
This also means that if an event messaging rule Timing was originally set to prepare/delay and you change it to send immediately, previously generated messages will not be sent immediately.
