When an announcement email goes out to our attendees or users of the site, we need to send out about 6000 emails.

A few thousand are SPAM/Bots, a few thousand are “inactive” accounts (opted out or moved), and the other 6000 or so are active users that have an interest in Desert Code Camp or have attended at least one. There is an API for mobile apps and future development, but that’s another story. Originally, the site ran on the Microsoft stack it used ASP.NET (Web Forms) and SQL Server. Many of you know that I run the Desert Code Camp in Chandler, AZ. The Problemīefore I go into the solution, let’s talk about the problem first.

Using SendGrid and emails are not being delivered to Hotmail/Outlook/Live/MSN.com recipients?
