Redirect Notice on Link in email

[Don Beck]

I am using the following command to send an email to over 500 employees

 gam sendemail file emailusers.csv subject "Announcement" ghtml ad...@domain.com 1NQcPdhpxpfhQXNGhRYqnxM_WZBzr6iS_3RUaC5ElQvc  

The process works great - everyone gets the email but mutlitple folks get a rediret notice when you click on the link.  The notice gives you the link to click on but I dont' understand why this is happening.  The google doc that has the actual link in it, is just pointing to where we want it to.

To add to weirdness, yesterday when I received the message on my computer, worked fine (no redirect) but when I clicked on the link in same message on my phone, I get the redirect and now I also get it on my computer ....
