An inbox in Slack is a channel where you can send & receive emails, tweets and Twitter Direct Messages. In other words, a channel open to external communications—e.g. set up an inbox in #contact to answer emails sent to firstname.lastname@example.org and tweets to @YourCompany. To create an inbox in Slack, just invite MailClark to a channel.
Note: You won’t be billed for dedicated conversation channels created when you hit the ‘Reply (new channel)’ button. They aren’t inboxes, they are ‘sub-channels’ stemming from an inbox.
Each month, after 50 emails & tweets have been sent/received in the free inbox, only the headers (e.g. author) are posted in Slack. Subscribing to a paid account allows you to view the messages’ contents and resumes normal posting.
If you’re on the Unlimited Plan, no worries, you pay a fixed $39/m for as many inboxes as your team needs.
If you pay per inbox, we wait till a few emails or tweets have been sent/received in the new inbox—in case MailClark was invited by mistake—before adding $9 to your subscription.
If you haven’t subscribed to a paid account yet, we’ll ask for your credit card after a few emails or tweets have been sent/received.
Type settings in a Slack’s Direct Message to MailClark, and then click the ‘Billing portal’ link under ‘Billing’.
