3. Click on cell E1 and enter the following formula: =HYPERLINK("mailto:"&A2&"?subject="&C2&"&body="&D2, "Send Email") This will create a hyperlink in cell E1 that, when clicked, will open up a new email addressed to John Smith with the subject "Hello!" and the body of the message containing "How are you doing today?".
