7 Day Course, with daily email at set time

Question:
[Clearly ask your question.]
I am trying to build a 7 day free course that people sign up to on my Wix website. Once they sign up I want a daily email sent with the content at a set time (ie 8am not a fixed 24 hour delay). People can sign up at any time.
As part of the initial set up, there is a pdf download and audio file.

I have tried programs but cant see how it can be an email rather than going itno the platform. I have tried email automations but you can only set a 1 day delay, not put a set time on it. Any ideas? Thanks in advance

Hey Kerry,

If the delay options available in Wix Automations aren’t fulfilling your requirements, then the entire automation logic will have to be custom coded using Wix Velo where Cron Jobs or Scheduled Jobs will have to be set up to fire these emails at a specific time of the day.

This will give you exactly what you want - fire an email at 8 am regardless of when a person signs up, but this would involve writing code.
