Work in Slack with clients / colleagues who only use email

← back to the Help Center

Even though you understand the advantages of Slack, maybe your colleagues or clients can’t be bothered to change their ways. With MailClark you can have a Slack channel with any combination of Slack and email users, where Slack messages are sent out as emails in a conversation, and emails are received as Slack messages.


Invite MailClark to your preferred channel

First things first, add MailClark to your Slack team if you haven’t done it already.

From the channel click on the settings gear on the top of your Slack window, select ‘Invite team members to join...’, then choose MailClark from your list of team members.

Or you can use Slack’s invite command—type /invite @mailclark #channel-name

Add your email address as email member

Still in the Settings window, type your usual email address (e.g. in the ‘Email members’ field. Save the settings.

Back in Slack, type a message—anything, it’s just a test. After a few seconds to see if you’re done typing, MailClark will give you a preview of your email—hit ‘Send email’.

MailClark will then ask you whether to start the automatic sending. Pros: no need to hit ‘Send email’, it’s all automatic. Cons: no preview, no cancel.

Go to your email account and reply to the test email you’ve just received. Your reply will appear in your Slack channel.
