Maybe I am getting old but I could swear I was able to add multiple people to forward email to in gmail.
My work around was to create a group .
This is for a board at my school . They want to have one email address and have mmultile people receive the email at once. I konw I can tell them to add this gmail account to their private gmail. Something I am trying not to do .
Other option was to create a group with all of their email address and then add those addresses to it.
