Hey Ingi Elsayed Abouzeid — thanks, this is super helpful. Yep I understand the workflow here: you want an obvious indicator in Heidi when an output/letter has already been emailed so you can quickly spot what hasn’t been sent to your admin staff yet. We’ll take a look at adding this and I’ll circle back if we need any specifics on how you’d like it shown (e.g. a “sent” badge, timestamp, or recipient).
