Mailbird’s Slack app integration brings chat to your inbox.

The user count on Slack has reached the 12 million mark back in October 2019. That’s a leap from 2.3 million in 2016 when we announced the app as one of the new Mailbird integrations for Business users.

If you’re new to Mailbird or Slack, read on to find out about Slack app integration and how you can use the two apps side by side.

Why We Added Slack to Mailbird

Slack is a great tool for teams to connect in the digital workspace. With Slack, channel members can communicate quickly, share documents, and the app has dozens of amazing bots to automate a score of things that email just can’t.

The Mailbird team has been using Slack for a while now, and we realized two important things in the process:

  • Although it can cut down on email between team members, Slack cannot completely replace it.
  • The best Slack integrations required yet another app or window that we had to juggle.

For these reasons, it made perfect sense to bring this team communication solution into the Mailbird interface. Now, you can have both tools open on the same platform through Slack app integration.

Activating the Slack App in Mailbird Is Easy

  • Click the “…” menu icon at the bottom of the Mailbird sidebar.
  • Next, click the slider in the Slack widget to turn it “on”.
  • You will see the Slack icon at the bottom of the sidebar along with any other apps you’ve activated.
  • Click it, and you will find instructions on signing in to your Slack account.

How do I integrate an app in Slack?

Here’s how to integrate an app in Slack: 
1. Choose the app you wish to integrate. 
2. On the app page, go to the Add to Slack button. 
3. Follow the instructions to install the app or connect your account. 

What is Slack integration?

Slack integration is a collaborative method of centralizing all your emails, notifications, and social media. Through integration, you can have a central location where your workforce can discuss and take action. 

Is the Slack app safe? 

Slack is a secure app, and you can use it to have confidential conversations. However, it is advised to practice caution using the app and never divulge your private information such as passwords, customer information, or other valuable company data. 

Which is better, Slack or Microsoft Teams? 

Although both apps are handy, which is better depends on your needs. For instance, Slack offers more integrations and is easier to use. However, Microsoft Teams plans are cheaper, and it integrates nicely with Office 365 tools.

    Looking good!
    However, I don’t get any notification when I get a new messages in the mailbird/slack app. Am I the only one with this problem? Any solution?

    The way you guys integrate stuff is an insult to the word integrate.
    Why don’t you just say “We’re showing it within an iframe and claiming we do integrate it since our current software is not capable of anything at all.”

    I noticed this post was in May, we are now in July almost August. Has Slack notifications been figured out yet?

      Hi Guys, slack app notifications is currently not being worked on by our developers. We are focusing on bigger features. I can’t say anything specific yet but you can expect something in the ball park of exchange support, multiplatform, and a native calendar for our future updates.

    This sucks says:

    Terrible. No notification support whatsoever. What’s the use of chat if you don’t know people are sending messages?

  • As of yesterday I am not able to use Slack on Mailbird. Would an update be coming out soon?

  • I get an error message saying “Please update your browser or use the Slack app” how can I fix this?

  • You still don’t have notifications for Slack. This is very infuriating. Slack itself is for productivity. If we don’t get notified, I don’t see any productivity.
    Also, I still see update the browser update request in Slack. Though it gives me an option of Skip for now, its just frustrating that I have to click it every time I open Slack.

  • I would 2nd, 3rd and 4th the Slack notifications comments. Absolutely pointless without it. I’m on a trial just now for a business account and what turned me on to Mailbird was integrations, but not having those push notifications or counters for when you receive a message makes them just pointless tabs and I won’t be taking out a subscription.

  • Slack inside Mailbird is still not sending any sounds or notification or even counter badge to visually see are there any new messages.

    Do you plan to fix this?
    Thank you

  • I just downloaded Mailbird and it’s awesome…

    EXCEPT that the whole reason I love it is because you can integrate Slack, Hangouts, Asana, etc, but there’s NO NOTIFICATIONS!! What the heck is the point of adding those “integrations”? lol It’s literally just a browser window that’s logged into the website for each “app”. It’s a joke.

    No way I’m buying any subscription with this.

    • Hi Jack

      There are notifications but not for all of them. We support notifications in whatsapp more will be coming in the future.

  • and another request for the same, this is now over 4 years old, I wonder how many original user requesting this are still with Mailbird? Bought the Business version to have Slack, didn’t expect it to be missing the vital part of notification. This is not an integration, it’s a quick fix that lastet over 4 years……. unimpressed and not expecting any specific response such as a timeline when this will eventually be done.

      Hello Peter! We would love to add notifications to the apps integrated in Mailbird but currently this is not possible for us I am afraid, apologies.
