A well-timed follow-up is key to closing a deal. Use this automation to remove the guesswork from the equation. After you set it up, Zapier will send you a message in Slack when someone opens an email you sent via Reply. "Funny, I was just reading your proposal," is what they'll say.

How this Reply-Slack integration works
