Posted on (0 Comments)

Historically, it was difficult to track transactional email. Developers were never sure if the email was delivered. There are various reasons email can be tripped up along the way. Email can bounce, ISPs can throttle you or you could be marked as spam. A lot of these problems can be avoided with a transactional email service, which will make sure your emails get delivered. But what about tracking these emails? Both marketing and transactional email can be extremely beneficial to a company, but flying blind to the data means missed opportunities. The type of data you can track includes notifications

The following is a guest post from SendGrid engineer Jeffrey Matthias. As a graduate of Dev Bootcamp, I am often asked for advice as fellow graduates begin their first job search.
