Automatic notification

Automatic Scheduled Email Reminders I'm building a Borrow & Lend tracking app and would love to have automatic notifications that send: - Daily reminder emails every morning (e.g., 8am) for items due soon - More frequent reminders (every 2 hours) on the actual due date - Ability to set custom reminder schedules for different items This would make the app much more useful since users wouldn't need to manually check and send reminders. Similar to cron jobs or scheduled tasks that run in the background. Thank you!
