The best way is to the use the built-in contact form for students. To access the contact form:
Log in to your Warp 9 account (it does not matter if it is a myTeachable account or not).
On the top-right side of your navigation bar, click your avatar. This will open a dropdown menu.
(See the gif)
On the Contact page, fill in the Subject and Message fields—similar to how you would fill out any other email.
Once you've finished your message, click Send. This will send your message as an email to the support team at Warp 9.
When we reply to your message, it will be sent to your email address; from there, you can continue the conversation as needed.
