How to Create a Shared Inbox in Slack?

Description: Find out why you need a shared inbox and how you can create one in Slack with the help of shared inbox tools.


Are you communicating officially with your colleagues on Slack? Slack is a widely popular communication tool for workplaces. It has channels that organize the company’s group discussion better, along with private chat. In a way, Slack is a boon for businesses as it helps carry out their internal conversations better.

Have you ever wondered about combining Slack with email? Let’s see how to create a shared inbox in Slack, but before that, find out what a shared inbox is.

What is a shared inbox?

A shared inbox refers to an inbox that permits several individuals to send, receive, read, reply and manage emails inside the same email account. It works well for teams because it lets all the teammates access the emails in real-time. A shared team inbox enables you to manage team communication and ensure transparency within team members which helps increase productivity.

In recent years, there has been a lot of noise to do away with email, but the trusted communication channel exists to date and is much in use. The fact that there are 4 billion email users all over the globe (2020), and every second more than 3 million emails are sent. To top it all, you have around 7 billion email accounts worldwide.

These stats are enough to ascertain that email is not going to vanish from the scene anytime soon. It is the basis of all business communication. People do all their official work by email. It is more like your identity online.

However, email is not ideal for teamwork which is its main drawback.

Why do you need a shared inbox?

The email is lacking in certain areas. The following are its main shortcomings:

  • You cannot share information easily – When you have a team, you have to share information. Usually, there is a pile of emails going to and fro with loads of CCing and forwarding only to make things confusing.
  • Teammates won’t take ownership – No one will know who has to take ownership of an email landing in an inbox if a team manages it. It can result in missed emails, or two people replying to the same email by mistake.
  • Slow replies – When teams are in direct touch with customers, they know the importance of quick responses. It isn’t easy to ensure that customers get quick replies when you use email for customer service teams.

That is why there is a need for a shared team inbox.

What does a shared inbox offer?

There are shared inbox tools that help you manage your team’s shared team inbox easily. A shared team inbox tool makes your inbox work as a complete email inbox, and it offers the following features,

  • Easy collaboration – All the team members can have access to the emails. When an individual replies to an email, all the members can see it, and if there is a deletion, it will get deleted for the whole team. It allows internal communication among team members and enables them to work on email collaboration.
  • Multiple communication channels – Shared mailbox tools help you manage messages across various channels like email, chat, SMS, and social media.
  • Collision detection – A shared inbox tool would detect collision and prevent two team members from replying to the same email.
  • Canned responses – The work of team members will get reduced when your shared mailbox tool deals with repetitive tasks. Some tools offer canned responses for the common queries of customers and can ensure accurate answers each time.

Who can benefit from using a shared inbox?

Teams can benefit the most by using shared inboxes. They are the best choice for public domain accounts such as an email address like info@, office@ or support@. Each team of the organization can have separate shared inboxes.

Here are the teams that can find a shared team inbox beneficial,

1. Customer support

A customer support team with fewer members would find shared inboxes useful as they can double-up into a basic CRM. As the shared mailbox holds the previous conversations with the customers, it would be helpful for the team.

2. Advertising and marketing agencies

As the communication history of clients is there in the shared inbox, it is all easily accessible and easy to search. In a shared inbox, it is even possible to assign emails to other teammates. It is possible to keep track of all the occurrences.

3. Accounting organizations

You can archive all the attachments in one place, and this works well for invoices. The account team can find this helpful. It is possible to gather information quickly in shared inboxes and get approvals from other team members using internal chat. It works in favour of not just accounts teams but also for other teams of organizations.
