If you would like to create an icon on your iPhone's home screen that will open Safari and go straight to webmail, here's how to do it!
Open up Safari and type in https://email.iljmail.com
Once you get to that page, tap the Share icon (it looks like a little box with an arrow coming up out of it)
Once you tap that, many options will show up. Scroll the page until you get to "Add to Home Screen"
Tap "Add to Home Screen" and a new screen will pop up to allow you to rename the text under the icon that will show up if you prefer (I suggest only having "ILJ Mail" in there or it will have those extra letters like in my example below.)
Now you will have an icon like above on your home screen you can tap any time to get to webmail within Safari. Just make sure to check your email regularly. For security reasons, webmail will log you out after no activity in 48 hours.
