SendGrid: Your Email Infrastructure in the Cloud

If you’ve ever built, managed and scaled email infrastructure to support your application, you probably noticed one common theme throughout the experience — email is really difficult!

If you haven’t experienced this first hand, then (1) consider yourself lucky, and (2) check out these tweets from people who have:

“…Can’t wait to rid my life of maintaining a mail server.” (see the full tweet[3])
“Oh, @sendgrid. You make my job so much easier…” (see the full tweet[4])

So, why is John so anxious to be done with mail servers and Rachel so darn thankful? Because they no longer have to deal with this stuff:

Poor Deliverability
Approximately 20% of emails sent by web applications never reaches the inbox! Many people don’t even know if their email is being delivered, until their users call to tell them that they didn’t receive their online purchase receipt or password reset notification.

Limits to Scalability
As email volume increases, so do hardware requirements. If you don’t scale your email servers efficiently, you won’t maintain reliable messaging to your users.

Lack of Understanding
You’re pretty sure the email was sent, but… …Was it actually delivered? Was it opened? Did the user click on the link? …Why did that email bounce? Who reported this message as SPAM? …Did the recipient unsubscribe from future mailings?


SendGrid was built with developers like John and Rachel in mind. With the help of dedicated and cloud instances from Rackspace, we replace your email infrastructure and provide everything you need to operate a reliable and scalable email system. Our service improves deliverability, scales on demand, and provides stats on all your email.

But wait, there’s more…

Simple Integration
You can be setup and sending email within minutes via SMTP rela[5]y. If you want to get fancy, use our SMTP API[6] or REST API[7] for complete control from your app.

Relentless Support
Our documentation[8] and libraries are improving and growing every day for your reference. But, most of the time we’re available via email, phone, live chat[9] or Twitter[10] to help you troubleshoot problems and optimize your deliverability. Because we intend to provide our customers with the best experience possible, we always welcome your feedback – the good and the bad.

APIs – beyond delivery
– Event[11]: notify a URL of events in real-time
– Parse[12]: parse incoming email replies and enable your users to interact with your web applications through email
– REST API[13]: send email, retrieve statistics or edit your settings

Solid Company
SendGrid is backed by top investors and advised by the brightest minds in the email space. SendGrid powers the email infrastructure of over 14,000 businesses and sends approximately a billion emails per month on their behalf.

Divide and Conquer

Back in the day, everyone rode a horse, but not everyone was a blacksmith. If you were the cobbler and you needed to re-shoe your horse, you went to the expert!

The same idea applies today.

Everyone depends on email, but not everyone should need to develop an expertise in email. At SendGrid we have one goal: to be the experts and to let everyone else focus on building much sexier applications.

Now that our friends at Rackspace have invited us to become a cloud partner, we’re happy to help accelerate the development of all the awesome apps and businesses built on the Rackspace Cloud.
