You can automate sending customized follow-up emails to new Typeform respondents using Zapier's workflow automation software, allowing for a smooth and scalable customer experience without adding more email responses to your to-do list. To set up this automation, you need to create a trigger in Typeform that sends information to Zapier, which then connects with Gmail to send an automated email to the respondent. The process involves selecting the form, connecting accounts, customizing the email content, and testing the trigger before using the Zap to send instant emails every time a new form gets filled out.
