Personalized Music Metrics from Pandora

I love my music and I love great emails, so this Email Inspiration post was a no-brainer! Sometimes, an awesome radio station can be the thing that gets me through an 8 hour workday, and I know that I’m not the only one who feels this way. Looking around the office here at SendGrid, I estimate 90% of employees have headphones/earbuds in at any given time.

When I work with music on in the background, I sometimes don’t even pay attention to what’s playing on the

Posted on (0 Comments)

To get a good reputation as a sender, one of the email best practices we encourage our users to implement is the double opt-in. It’s actually a very simple practice: after a user gives you his/her email, you store their information with an authentication token and a boolean variable.

This link will have their token and take them to a URL that will make a request to the

When you communicate too often with your recipient list, you can dilute the importance of your messages and annoy your recipients because you’re flooding their inboxes with information that may not be relevant to them.

While you may only want to inform your list, recipients may not want all those emails.
