This works well enough on iOS https://scheduledapp.com
"Had a follow-up question for a client that just occurred to you at 1 AM? Want to write a heartfelt thank you to be texted at a later date? Unfortunately, neither SMS nor most messaging apps – including iMessage – allow you to draft a text in advance and schedule it to be sent out on a later date. But a new iOS application called Scheduled can help"
I'd love to get this working using Automator or at with a script
