1. Begin by creating a form and submitting it with your name, email address, topic, and message.
2. Include a statement outlining the purpose of the contact form and what will be done with the user’s information.
3. Add a captcha or another method to ensure that the form is not being filled out by a robot.
4. Set up an email address or another method for people to contact you. Make sure this information is available to users on your app’s website or elsewhere.
5. Check the form carefully to ensure that all entries have been made.
6. Lastly, think about adding a thank-you message or sending users to a proof page after they submit the form to show that their message has been received.

Remember to answer quickly to any questions or concerns your users have so you can build a good relationship with them and make your app better overall.
