Add Auto welcome email

[peterdudfield]

It looks like we can send a custom email but we need to set up email provider first on Auth0

@braddf

you ever set up any of these before?

[braddf]

@peterdudfield yep I have used Sendgrid, Mailgun and Mandrill before – much over muchness I think they were all fairly easy to set up/integrate

Ill put the feedback in here
1.

This is a little bit raw, so could be made a page

2. Could also add an email address to contact OCF with in this message. quartz.support@openclimatefix.org
