Welcome to the community, Rachel! :grinning_face_with_big_eyes:

Airtable’s native features don’t allow that kind of controlled, isolated view at this time (unless you like manually making individual views for each attendee).

Aside from using the SendGrid block (which I haven’t used yet, but which might work for your use case with their free account depending on how big of a list you’ve got), there are also integration services like Zapier and Integromat which can do the job. I use the former to send quick confirmation emails when people fill out an Airtable reservation form for an event I’m coordinating. It’s only a two-step zap, so it can be done with the free account. Either of those services would also work if all of your event attendees are already in your base and you want to send additional emails, though they each have data and action limits on the free accounts.

Our form extension generates an editing URL for each record in your table. You can use Airtable automation to email each individual their own unique URL to update their record.

There’s also an option to add a login page to your form. Which will allow the users to look up their records.
