I am using Power APPs to trigger Power Automate to send notification emails to users. I chose SMTP connector because I don't want to use user's email to send notifications, we need to send about 50 emails per day, but 20% of them are failed with the error codes 502 and 504 BadGateway. Can someone help me? Thanks all!
