hello @Heli.Levy, welcome to the Tulip Community!! it would be great if you could introduce yourself at: Welcome to the Community, let’s meet! !!
sorry to hear about the issues with the Emails not sending, I haven’t heard of this issue occurring in the past. just to confirm, do you not have any Conditional statements that could be preventing the Emails from sending?? if you could share a screenshot of the Trigger that is sending the Email, we can look into what could be causing this.
thanks, and welcome to the Community!!
