Gmail

Step 1: Create a Template using Mailchimp

• Go to Campaigns → Email Templates → Create Template and design the email template (note: mark the merge fields clearly)
• Upon finishing, click "Export as HTML" and save the file

Step 2: Set up Zapier

• Follow the steps from this article to set up the "when this happens..." part.
• Add a "do this..." part. Choose "Gmail" and "Send Email".

• Proceed to Choose Account and log in to your Gmail account
• Proceed to Customize Email and fill in the fields accordingly (select "HTML" for Body Type)

Step 3: Edit HTML in Zapier

• Paste the HTML from Step 1 into Body, and replace the merge fields with data fields

• Delete the built-in parts (highlighted below) from Mailchimp. The clickthru links won't work when sending through Gmail, so there's no reason to keep them.
• "View this email in your browser" towards the top

• "Unsubscribe" section towards the bottom

• Potentially other sections depending on the template you chose. Please reach out to @Ben Xue if you need assistance.

Step 4: Test & Done!

• Test it, turn on the zapier, and enjoy the magic of automation! Now your email receipt will send automatically every time a payment comes in.
