Email Reminder for a Specific Time and Date

Reminders are processed overnight and will be sent early on the morning.  They are not able to set set to a specific time of day.

Alright. How about sending an email once you save a +New Log? Is that possible?

A Notification is an email which gets sent instantly when a record is saved.  You get to qualify it's triggered based in which fields changed, and any conditions being met after the record is saved.

When setting it up, carefully initially choose if it is going to go to internal QuickBase users (Recipient Type) or external random email addresses (Open Type). Note also that if it going to be an Open Notification, then you can in fact enter one or more  [field name] in square brackets in the TO box.

I think reminders only work for internal email addresses.  In your note, you mention that it can be sent to external users?  Am I missing a way to do this?  Thanks!

Yes, I reminder is really more like a Subscription that only fires once.  So yes, Reminders only may fire to Internal Users.

Where is the tab that takes me to the screen with "Follow-up Details?

Huh?  I don't understand your question.
