In your base, you would need to attach a user to each record that you are planning on emailing to someone.
To do this, you would either:
(1) use a User field
or
(2) use a linked record field where you select your user from another table, along with a lookup field which looks up the user’s email address from that other table.
Then, you would pull from those fields in your automation.
For a training lesson on linked record fields and lookup fields, check out my free Airtable training course, which you can take for free by signing up for a free 30-day trial with LinkedIn Learning.
p.s. If your company has a budget for your project and you’d like to hire an expert Airtable consultant to help you with any of this, please feel free to contact me through my website: Airtable consulting — ScottWorld
