Easily Post an Email to Slack Channel with Mailparser

Post Emails to Slack Channel

Slack quickly dominated workplace communication tools with more than 10 million people using the application daily. And if you wonder why, their mission is nothing less than to “change the way we communicate”. Slack is an excellent tool if you want to ditch internal emails and improve communication within your team.
But did you know that you can also use Slack to keep your team up to date with important notifications? For example, if you made a new sale or a status update coming in from another platform, our Slack email integration allows you to send emails to Slack with just a few simple steps.

Use Webhooks to send important data from email to Slack automatically

Slack offers several APIs (SlackBot, Real-Time Messaging, REST, Webhooks), and the possibilities are endless. But if you just want to post messages to one of your Slack rooms, the easiest way is to use their Webhook API.  The good news is no coding skills are required for this.

Using Mailparser in combination with Webhooks is an easy way to post data from email to Slack.

This kind of setup became quite popular amongst our customers recently. It is effortless to pull out data trapped inside emails and automatically post it to a specific Slack channel. This way, you can keep your team up to date with homemade custom integration.

Parse important notifications from emails and send them to any Slack channel

If you need some inspiration, below you’ll find some of the use cases we already know of. Maybe you have another one? If yes, please let us know, and we’ll add it to the list.

Post to Slack each time you make a new sale

If you are selling products online, the chances are high that you receive an email each time a transaction comes in. With Mailparser, it is easy to pull out specific information from these emails and push a sales notification to your team on Slack. We are pretty sure they’ll love it!

Post to Slack when you get an alert email

If you are using monitoring services for your website, you probably receive emails containing warnings, errors, or any kind of alert from time to time. Mailparser lets you easily pull the content from these emails and post a message with our Slack email integration.

Connect your Project Management Tool to Slack

In case you are using a project management tool that is currently not supported by Slack, the chances are that you can still push some status updates to Slack. If you receive the status updates by email, you can automatically forward them to Mailparser. Our email parsing engine can then parse all vital information, and a webhook will be sent to Slack with all the critical updates.

How to post data from email to Slack:

Connecting Mailparser to Slack is easy. Once you have done the initial setup, all you need to do are the following steps:

  1. Create an “Incoming webhook” at Slack
  2. Create a Webhook Dispatcher in Mailparser
  3. Use the URL given to you by Slack as the target of your Mailparser Webhook Dispatcher
  4. Set the Data Structure of the webhook to “Custom” and use this:

{“username”:”MySlackBot”,”text”:”Here is some text containing your variables.”}

What is Slack?

Slack is a workplace application helping organizations communicate internally. It’s described as “a single place for messaging, tools, and files.” Do you remember the days of AOL Instant Messenger? Slack is basically that but for the workplace and hundreds of integrations. The integrations aren’t necessary for primary use because Slack’s main function is only communication. 

There  are two ways to chat in Slack:

  • Slack channels (group chat)
  • Direct message (DM) or person-to-person communication

Slack is a workplace water cooler, conference room, cubicle, group chat, meeting space, or anything you need. It’s a collaborative tool to help you better communicate with your team, whether synchronously or asynchronously. 

Other Slack attributes:

  • You can create public and private Slack channels. The channels are virtual meeting spaces for your team to share tools, files, and ideas to improve your projects.
  • Slack has over twenty-five hundred application integrations, including Jirabot and Jell
  • You are protected with Slack’s data encryption and safety protection. 
  • You can connect with other friends and colleagues outside of your organization with SlackConnect.

With every message, you can read and reply to the messages in a thread using text-based responses, emoji reactions, adding gifs, seeing RSS feeds, setting reminders, and other integrations. Companies love Slack for its accessibility; users can use it on desktop, laptop, and mobile devices to receive messages and push notifications every second of every day. 

Why use Slack?

At the time of Slack’s release, there were only a handful of competitors on the market, Hipchat being one of them. What set Slack apart from others was its intuitive design and integrations with other applications. Hipchat was hesitant to add third-party integrations and lacked an entry-level free version for small companies, making Slack a success with startups.

Also, Slack’s size was a benefit in the beginning. Slack was a small company that could work diligently to add new features like emoji reactions (which makes communication more fun) and 2FA (2-factor authentication. 

Slack is really good at two things:

  1. Design/UX (user experience)
  2. UI (user interface)

These are the twin columns that every company and application needs but are challenging to pull off well. 

Stewart Butterfield (co-founder of Flickr in the 2000s) created the first iteration of the application and then sent it off to MetaLab to burnish. Andrew Wilkinson, a MetaLab developer, said, 

“To get attention in a crowded market, we had to find a way to get people’s attention. Most enterprise software looks like a cheap 70’s prom suit—muted blues and greys everywhere—so, starting with the logo, we made Slack look like a confetti cannon had gone off. Electric blue, yellows, purples, and greens all over. We gave it the color scheme of a video game, not an enterprise collaboration product…vibrant colors, a curvy sans-serif typeface, friendly icons, and smiling faces and emojis everywhere.”

Wilkinson also talked about how he and his team were avid users of Campfire and tested out the various copycat products that came out through the years. He didn’t think the wheel could be reinvented…until it was.  

“We prefer to just put our heads down and design stuff, iterating over and over again until something feels right. Slack was no different — there wasn’t any magic process we used — but looking back, I’ve identified a few key things that helped make it the huge success it’s become.”

And he’s right, it was almost identical to every other chat application that came before, and especially Hipchat. Here’s a side-by-side comparison of the two: 

hipchat vs slack
Hipchat (left), Slack (right). You don't have to see them close up to notice clear aesthetic differences.

Just like Hipchat, you could create rooms, add users, share files, chat as a group or send a DM. But he said three key differences made Slack stand above all others:

  1. It looked different.
  2. It felt different.
  3. It sounded different.

To make it look different, they used bright colors to make the app pop and look like a video game; so colors like electric blues, yellows, purples, and greens. Other apps were stuck in the 90s with their muted blue colors. 

They added a colorful logo and made certain elements pop off the screen to make it feel different. 

To make it sound different, they gave their brand the voice of a human and not a human-robot. 

“Slack acts like your wise-cracking robot sidekick, instead of the boring enterprise chat tool it would otherwise be,” Andrew continued.

All of these reasons contributed to Slack’s success. The functionality is equally as fresh and intuitive as the design. In addition, slack’s developers focused on what users wanted from a chat app over the general enterprise-level requirements of sending messages to one another.

Another prominent selling point was its privacy in DMs and private channels. Slack administrators couldn’t read the messages without the open consent of the members or a message sent to all users in the DM or chat saying that a message export occurred—this built confidence in the security of the product.

In 2018, GDPR legislation in Europe changed the way exports occur–administrators in higher-cost plans can fully export chats without informing their users. Users valued the original legislation Slack rolled out. Slack always understands what its users need from an app. 

Early on, Slack pushed app integrations, and now there are over 2,500 integrations for tools like GitHub, Jenkins, Google Analytics, Jira, ServiceNow, MailChimp, or its owner, SalesForce. These integrations make for a smoother workflow–users can go about their work while Slack sends them notifications from their various integrations. 

Now that we know why Slack is a global communication sensation, let’s learn how to push data with our Slack email integration channels and build your own custom Slack email integration.
