What is a connector?

A connector is an external communications account connected to a Slack channel via MailClark.
It can be an email account, a Gmail/GSuite account, a Twitter account, a Facebook page, a Google Group, an email group or a new email address provided by MailClark.

More details about connectors

What happens when I reach the limit of the Free plan?

Each month, after 100 emails & messages have been sent/received, only the headers (e.g. author) are posted in Slack. Upgrading to a paid account allows you to view the messages’ contents and resumes normal posting. Check out our pricing page for more details.

I’ve just added a new connector, how will that be billed?

If you’re on the Unlimited Plan, no worries, you pay a fixed $29/m for as many connectors as your team needs.

If you pay per connector, we wait a few hours—in case the connector was added by mistake—before adding $3/m to your subscription.

How’s MailClark different from Slack’s official Email and Twitter integrations?

Slack’s official integrations only allows you to receive emails & tweets. MailClark is a both-ways integration, so you can send and reply to emails & tweets directly in Slack.

Besides, MailClark allows you to connect Gmail / G Suite accounts, Facebook pages, Google Groups and to create email groups.

Do you offer discount to non profit organizations?

Yes. If your organization has been approved for the Slack for Nonprofits program, we’d be happy to offer your team the Unlimited Plan (worth $39/m) free of charge.

In return, we kindly ask you to add a link to on your website.

Note: We do not offer refunds for subscription fees paid prior to being approved.
