Most of us spend all day reading and writing email. What if you could also send and receive SMS messages using email? How would you do that? That’s actually a question that we get fairly frequently, so I built an example application that does just that.
In this this blog post, I will be showing you how to send and receive SMS messages via email using Python, Flask, SendGrid, and Heroku.
I will cover how to configure and connect all of those services to set up your own “SMS via email” service. If you haven’t used Twilio, SendGrid, or Heroku before, this will be a great time to learn more about how they work.
The example code in this post turns SMS messages into email messages, the first line of your replies to those email messages will be sent back the the sender via SMS. This example code also allows …
On July 20, 1969, at 20:18 UTC, Neil Armstrong was the first human to set foot on the Moon. Video of Neil descending the ladder of the lunar module was broadcast to earth at 10 frames a second via an image transmission method known as Slow-scan Television, or “SSTV”.
Today I’ll be showing you how to use the space-age technology of SSTV and your telephone to do something critical to human progress: look at pictures of cats.
We’ll be using an SSTV transmission mode called “Martin M2”. Martin M2 is an SSTV transmission mode which is popular with European Ham radio operators and differs significantly from the system that NASA used to transmit images back from the moon.
Keep in mind that this post is just for fun and a little complicated. If you want an easy way to send pictures to mobile phones, you should look at …
Since writing this post, we’ve created a new tutorial showing you how to quickly add two-factor authentication to your applications updated with some more recent techniques not highlighted below.

Why Two-Factor Authentication?
Back in the day, it used to be that enforcing a strong password policy was sufficient to prevent unauthorized access into your user’s accounts. (Ah, those were the days, when kids were polite and respected their elders). However, as the security landscape continues to evolve, it is becoming clear that a strong password policy is not enough any more. Today, an attacker can discover your user’s password in a variety of ways: th …
If you are a web developer, you know that handling file uploads is not fun. You are either spending time dealing with files and permissions, or learning how your language handles MIME multipart encoding. Then there is the problem of dealing with large file uploads and cross-browser compatibility.
Even when you get the basics figured out, all that you have working is something that allows your users to upload files from their computer. If you want to enable your users to choose photos and files from a service like Facebook, Dropbox, Google Drive or Flickr, well, that’s a whole other story. Integrating these different APIs, normalizing response formats, and maintaining these integrations c …
TwilioSheet is a little utility that makes it easy for developers to receive SMS messages in a Google Spreadsheet.
I write a lot of simple little SMS applications, but they can be daunting at times. I often wonder if the idea is worth the time it takes to write the code to store, process, and act on the incoming messages. Why not use something a little easier? A spreadsheet perhaps? Well, that’s what TwilioSheet lets you do.
Once you’ve set up TwilioSheet, SMS messages sent to your Twilio number will show up in your spreadsheet after a few seconds. You can easily process the SMS messages that are coming into your spreadsheet using built-in spreadsheet functions or you can write your own …

My name is Joël, I recently joined the Developer Evangelism team at Twilio. The main reason I joined Twilio was because it gave me the chance to help developers, which is one of the things I love to do.
What I didn’t expect when I joined was that I would have so many opportunities to make a meaningful impact so soon after starting.
One of these opportunities was a project where I helped the Utah Foster Care Foundation. For the past 10 years, the Utah Foster Care Foundation has held a Chalk Art Festival to “shine a spotlight on the needs of Utah children in foster care [...] and raise funds that benefit these deserving children and families. “
Recently, this festival has included a People’s Choice Award that allowed festival visitors to vote for their favorite entry via SMS. Naturally, this …
