You should stick to one method. The API should take care of your unsubs, monitored email boxes is if you don’t have an API feedback loop. Did you verify if the API loop is working? Thx, Joey ---

I did tried testing the API integration via Sendhook but didnt got any results - my facult that I too ignored it and made in enabled. Shall I disable the webhook and keep rest of the settings and test it ? - though should have tested it no :~( ---

Sorry, I only do API (Especially Amazon). I found the bounce processor too unreliable on my setup. Can’t hep with that. Maybe you should open a new Forum Topic with the Subject ‘Sendrid API help’. Joey ---
