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

Once invited, MailClark automatically creates an email for your channel in the format channel@team.mailclark.ai (you can change it later on).
Test this address by sending an email there from your usual email account (e.g. Gmail). It will appear in your Slack channel.

For testing purposes, click on ‘Reply (here)’ to answer directly in the channel where you’ve received the email.
‘Reply (new channel)’ allows you to organize concurrent conversations with different senders in their own channels. We believe it is easier to understand the progression of the conversation by going into a channel which only includes messages to and from a certain sender than scanning through all received emails.

Whether you’ve created a new channel or not, now type a reply to yourself. MailClark will wait a few seconds, to see if you’re done typing, then give you a preview of your email. Hit ‘Send email’—your reply will appear in your email account.

You’re now sending and receiving emails in Slack!
