You could even hack together your own solution using IFTTT (If This Then That), a free service that connects together a variety of apps. In this case, you can set up a process, called an "applet," where sending an email to an IFTTT address will automatically trigger an update to your reading list. Start by signing up for a free account. Then access the main menu by clicking your avatar in the top right corner, select New Applet, and set Email as the trigger. For the action, choose the app where you plan to store your reading list: You can have these emails trigger a change in Google Drive, Dropbox, or the iOS Reminders app.
