The author, a web designer at Mr. Technique, uses Zapier to automate form submission checks for their clients' websites. This automation saves time and reduces inbox clutter by sending an email to the client as soon as a form is submitted on their website. The process involves setting up a workflow in Zapier that connects with Gravity Forms, the form provider used by the author's clients, and sends an automated email to the client using Gmail. The automation includes dynamic data from the form submission, such as the visitor's name, which makes the email seem personalized. By automating this task, the author can focus on other tasks and follow up only with submissions that were not received by the client.
