How to find out if the email notify left?

Hello, how can I check if email notify was send ? Is it possible to get the status if the email does not go out? (internet, email server, etc. are not working) ? If no email is sent, I would like to use sms notify in the automation.

Sorry for my english.

I am not exactly sure if this will work as it depends on what your email account is capable of
Connectins/inet/etc…you donot need to check…only if sent within a certain timeframe

  1. verify if your email account can setup confirmations of delivery OR use another BCC- account to verify that the email went out, i.e. always send an email to the BCC account
  2. then setup a IMAP integration and search for words in the incoming email
