Can you be more specific about this "database/data store"? The nature of that will limit your options. If it's just a big ol' CSV or something similar, you might be able to just use a nocode/lowcode tool like Airtable or Make.com to automate it in a few minutes. If it's something particular SQL database that you need to write a query to extract data from, it gets a bit harder because you need to connect that layer to the automation layer and then connect that to a transactional email service with good deliverability. If you can give a clearer picture of details, like what kind of data format it's in, how many people you need to send it to, how often will the underlying data change, etc., it would help narrow down the options. There are approx. infinite ways to build this, but it can be very simple or more complicated depending on the details.
