Do you find yourself updating clients, customers, or coworkers on the status of a project or case? If you're writing and sending the emails yourself, you can actually let Zapier do it all for you. With this integration, when you update a Trello card—say, check off an item in your checklist—Zapier will look up a row in Google Sheets, where you can house specific, pre-written messages. Then, Zapier will use those messages in your email and send it off in Gmail.
