i just got my warp and i love it, its a great phone, my first android phone, and i get email to text from my dispatch, since i am on the fire department, and i want to set up a ringtone for that email, so when i get a call and it sends me an email my certain tone goes off and i know i have a call. but i am having trouble doing this, i have the email saved in my contacts but it wont let me set a ringtone because there's no phone number
