Thanks for your message Ralph,
For the one of the automation events, I use an email address linked to the company I work with. For the other, I use my personal email address. Both automations cause triplicates.
In both cases, the emails are sent via the company’s email server.
Should I try another email server?
By the way, I receive another automated email when changes are made in a table, and this only sends one email, not three. I had issues with this before and it was resolved in this forum post: https://forum2.seatable.io/t/automation-doesnt-fill-out-column-in-email/2734
