Summarize the following:
There isn't a direct email address for Sprint, but there is a website where you can submit an email. Go to https://www.sprint.com/en/support/contact-us.html#tab-landline and then choose "Email us" in blue. From the drop-down menu that appears, choose the option that best matches your issue. Then enter your name, contact information, and question. Once you're finished, press "submit" in the bottom right-hand corner. Although you submit your email through the website, the response from Sprint will come directly to the inbox of the email address you entered. It can take up to 24 hours to get a response, so be patient if you don't hear back immediately. Make sure you check your junk mail - if your email provider doesn't recognize the address from Sprint, it might automatically send the response to "junk."
Go to the website with the email form. Enter your contact information and issue into the email form. Look for a response in your inbox.
