The name at the bottom of the message (if you type the URL as seen in OP's text message into your browser and open up the message) is:

Everbridge Software company with a little logo "

I looked up 'Everbridge Software': https://www.everbridge.com/

And, a website came up with that same name and logo. and which described the company this way:

Everbridge, Inc. is an American enterprise software company that offers applications which provide information about critical events to help with personal safety and business continuity. Formerly known as 3n Global and the National Notification Network, Everbridge began operations in 2002.

I also did a search on just this: https://evb.gg (as seen in the text message from OP).

Instead of bringing me to the Everbridge website, I got a completely blank screen with these words on it:

Your New Application is ready. in bold print! At the top is a tab which says, "Welcome to Play".

HELP! DID I just release spyware into my computer?

Anyone know??
