Do you know people that are glued to their text messages but hardly ever check their email? Yeah, me too. So if, for example, you want your child to at least be aware you sent them an email, they can set themselves up to automatically forward your emails to their text messages, at least if they are a Gmail user.
The link below shows how to get that set up and the image below shows I'm forwarding someone's email to my text messages using my cell number followed by "@msg.fi.google.com", which is the format for my cell service, Google Fi. Verizon uses your cell number followed by “@vtext.com”.
