How to Send Emails in Bubble.io Using Email API

A tutorial explains how to build a no-code contact form in Bubble.io and connect it to Mailtrap’s Email API through Bubble’s API Connector plugin. It covers creating a form with name, email, message, and optional file-upload fields; configuring a POST request to Mailtrap’s send-email endpoint with JSON headers, an API token, and dynamic parameters; initializing the API call; and linking the form’s values to a button-click workflow. The instructions also describe sending plain-text and HTML messages, noting the different placeholder format needed when using raw request bodies containing HTML, as well as attaching files through Base64-encoded content and delivering a message to multiple recipients by adding entries to the recipient array. The process is intended for users with basic Bubble familiarity and a Mailtrap account, with email delivery results verified in Mailtrap’s Email Logs.
