Make the switch from email to Slack

Insights for email veterans on how to replace cumbersome email workflows with simpler, channel-based messaging

We designed Slack to replace emails inside your company and improve the way that your teams work – whatever their location. Making the change is easy (and here are our favourite reasons for doing so). Plus, many of your most critical email workflows map closely onto Slack. Let’s look at how you can not only re-create them but improve on them too. Are you brand new to Slack?

Before diving into the tips below, quickly run through our Slack 101 tutorials. You’ll learn how to:

  1. Set up Slack
  2. Find and start conversations with your teammates
  3. Work in channels, where teams share ideas, make decisions and move work forwards
  4. …and much more

1. Say goodbye to messy email chains and hello to channels

If emails are your most frequently used communication tool, digging through lengthy reply chains to find the right file or update is ‘just part of the job’. The default view of a typical email inbox is a list of your past 50 emails, which could be about anything on earth.

In Slack, all work and conversations are organised into channels instead. Each channel is a single place for a group to share messages, files and key decisions around a topic. And, just as you can create your own customised email folders, channels can be created around projects, topics and teams.

Find and create channels in Slack

Anyone in your organisation can join channels, and you’re likely to find that topics that you might create email filters for, such as announcements from HR, already have a dedicated home in Slack.

If a channel doesn’t exist for a particular topic or project, create one, for example #proj-brand-campaign.

Then add each person involved, along with key files. Every decision and update about the project can exist in that one, easy-to-find place, and you can move work forwards together.

2. Give the right people visibility, no cc’ing necessary

Everyone knows the feeling of missing a critical update because you weren’t cc’d on the chain. Most people purposely overdo this to be safe, adding an entire team of people to any email that mentions one aspect of their work.

But when messages are shared inside a Slack channel, every member of the channel gets the same visibility.

How it works in Slack

Let’s say that you have a design question: Where can I find our latest set of brand guidelines? Post your question in the #design-team channel, and any designer in your company can reply there with the answer.

As you work in channels, your conversations and files become a searchable archive. When people have a similar question in the future, they can search for ‘brand guidelines’ in the #design-team channel and find the answer.

3. Highlight customised keywords to never miss an update

People who spend their working day using emails frequently use keywords in subject lines to filter out messages. Let’s say that you’re working on a project with the code name Xanadu. You would probably create a filter keyword so that any email with the word in it automatically goes to a folder called Xanadu.

In Slack, you can also set keywords so that whenever they’re mentioned, they will be highlighted and you will receive a notification. So, even though you might have a #proj-xanadu channel to discuss everything related to the work at hand, whenever someone mentions the name of your project in other channels, you’ll also get a heads-up.

Create your own keywords

Select Preferences in the workspace menu to view your notification settings. Add keywords that directly apply to your area of focus (and if you find that you frequently receive notifications for unrelated messages, you can prune your word list).

4. Mark messages as ‘unread’ to come back to them later

People often use their main email inbox as their to-do list – setting important messages as ‘unread’ until the requests in them are complete. Slack lets you do the same.

How it works in Slack

When you get an important message that you want to revisit later, long press on mobile and tap to mark it as unread, or click on the message menu on desktop.

You can also set a reminder that will prompt you later from the Remind me about this option.

5. Let coworkers know when you’re out of the office (or simply busy)

Anyone who’s used emails is familiar with automated responses that say something like, ‘I’m out of office for the next two weeks on leave. If something is urgent, please contact my team.’

With Slack, setting a customised status does this very job. Use it to alert others about impending time off, or to let them know when you’re away and when you will return.

What your teammates will see in Slack

Slack comes with five default choices for status, including 📅 in a meeting, 🤒 out sick and 🌴 on holiday, but it also allows you to create any customised status. If your teammates begin to write you a direct message, they’ll see your status. Then they can move ahead knowing that it’ll take a while to get an answer. Or they can set a reminder to follow up when you’re back.

6. Hone your messages in Drafts

If you want to jot down a quick idea or are working on a big announcement, click on the New message button to create a draft. Click on the message area below and use it as a notepad to develop messages that you can send later.

Decide at your convenience which channel or coworker will receive it when it’s ready. They’ll always appear in the menu under Drafts.

7. Replace one-line emails with emoji

There’s an old saying around most offices: the best emails are the ones that were never sent. The worst? Every note that bluntly says ‘OK’, ‘Sounds good’ or ‘Looking at this now’. In Slack, you can use emoji reactions to communicate these points in a click, without cluttering anyone’s inbox.

How it works in Slack

Let’s say that someone asks you to review a contract in your #team-legal channel. When you’re ready to review it, mark the message with the 👀 emoji as a reaction (anyone can mouse over that emoji to see who claimed the task). When you’ve finished reviewing, mark the message with a ✅. If any changes are suggested, those can be left in the document or as a reply in a message thread.

Here are some other time-saving emoji reactions to use:

  • ➕ = I agree
  • 👌 = OK, or I understand
  • 🎯 = That’s exactly right, you’ve nailed it
  • 👏 = Great job, or well done

Advantages of Slack over email

In addition to the concepts that carry over from email, Slack unlocks plenty of new opportunities for your team.

Onboard and get to work right away

Raise a hand if you’ve joined a project or started a job… and have been stuck waiting for messages to arrive to provide context. When you join channels in Slack, you can simply scroll up to see all of the context, conversations, ideas and decisions that have been made to date.

Get to the point quickly

There’s no need for a generic greeting, subject line or closing salutation in Slack messages. You just type your request. Multiply that by hundreds of interactions a day, and you’ll quickly realise how much time you can save in a year across your entire workforce.

Cut down on context switching

Slack is more than a hub for conversations and files – it also connects with more than 2,200 other apps that you might already be using. Use those apps to get file previews and grant access to others, report on Slack when tasks or milestones are completed, receive calendar updates and more – all without switching between windows or tabs.

Stay looped in by default

While emails restrict conversations to the people included in the To and Cc fields, everyone in a channel sees the same conversations. That means that anyone in the group can pop in to see progress being made, view the latest drafts and mockups and check on outstanding approvals. As a result, weekly status meetings can focus on larger milestones and challenges (or be done away with entirely).

Keep track of important information

Don’t let vital info get buried in an inbox. In Slack, you can save messages for your own use and pin messages to channels for everyone to see. Use either to track and highlight what’s important to you.

Reach teammates faster

No matter where you work, you’ve probably experienced the universal problem (especially when you’re new) of not knowing where to find people or who to ask for information. In Slack you can see everyone’s profile, search for their recent contributions to get a feel for their areas of expertise, and reach them via direct message. If your message is time-sensitive, you can mention them directly to get their attention with a notification.

Streamline communication with partners

If you’re on a paid version of Slack, you can bring all these benefits to your work with external organisations through Slack Connect. Use channels in Slack Connect to keep clients, accounts, agencies and partners in the loop and give everyone a shared view of progress and success.

This way of working also means that you don’t have to waste time wondering whether to contact someone using SMS WhatsApp, email or Facebook Messenger. Instead, all of your workplace communication is in one tidy place: Slack.
