In this blog post, I show you how to use Flask (A Python Microframework), hosted on Microsoft Azure, to capture messages regarding email failures sent from the SendGrid Event Webhook. We then create OneNote pages, that contain follow-up actions, based on the particular email failure. Prerequisites This code was developed using Microsoft

Posted on (0 Comments)

Email deliverability is influenced by a lot of factors, including signing your mail, keeping clean lists, sending wanted content, having a good sending reputation, and much more. Your sending reputation is how ISPs identify you as a legitimate sender. Every time you deploy an email campaign, you are providing them with valuable data that says whether or not you follow proper sending practices.

What we’re actually listening to is a different conversation, but music is a staple around here. When I work with music on in the background, I sometimes don’t even pay attention to what’s playing on the
