BenkoBot is like ScriptRunner for Trello. It picks up where Butler Bot left off by providing a powerful and easy to use, hosted wrapper for Trello's API based on the open source Trellinator framework.
BenkoDesk allows you to share a Gmail account via Trello. Unlimited team members can send and receive emails and keep track of tasks and priorities, replacing more expensive options such as HelpScout.
BenkoBoard lets you use Trello as a Gmail client. Gmail threads are linked to Trello cards, and you can reply, create new emails, cc, bcc and send attachments directly from Trello.
