If you want a separate email for each record, you need to trigger each record individual.
One option is to change the trigger. Instead of using the At scheduled time trigger, use a When record meets conditions trigger. Use a formula field to approximate the time based on NOW(), and whatever other conditions you have for your Find records action. Note that NOW() is not exact, and can be off by as little as 5 minutes or as much as 2+ hours.
Another option is to take a two phased approach. The first automation has the trigger At scheduled time and it does a Find records action. Then, the automation links all of those records to a special “control” record. The Update record action can update a single control record, but it cannot directly update multiple records. Linking all of the records to a control record triggers the second automation. This second automation looks for the presence of that linked control record, and then sends the actual email, and unlinks the individual record.
Integromat automations will have at least 2 advantages for you:
Precise & advanced scheduling of your tasks, right down to the minute.
Emails are always sent individually. Emails are never sent in groups unless you specifically use the Array Aggregator to combine email addresses together into an array.
Your entire automation scenario would be as easy as 2 simple steps… check out the screenshot below:
You would click on that little clock icon to setup your daily schedule at 12:00pm.
You would setup your Airtable search with that blue “Search Records” ball.
This screenshot uses Gmail (or Google Workspace) to send the emails, but you could use any email sending service that you’d like.
p.s. This is pretty easy & straightforward to setup, but if you need to hire an expert Airtable consultant & Integromat Expert+ Partner to help you with any of this, please feel free to contact me through my website scottworld.com.
