Send an email to an address inviting them to the app and including a link to join the group

[Smushed]

Probably going to need to be brought in with another table. I can see this becoming an issue if someone blasts out emails.
Also want to save down the group that the user whos email it was sent to so they can easily access the group to join. See below for how the URL should be structured on the website when the link is sent

Something like
EmailSent: {
emailAddress:
dateTimeSent:
userSentBy:
groupRequested:
}

Create a link which is then able to be followed? Like /signin?groupName=eliminator

So if the signin is completed and the query has a route in it then the user is automatically added to the group
