Story

As someone who is invited to a portfolio
I want the system to send me an email notification
so that I know when I've been invited.

Acceptance Criteria

Send emails:

• When someone is invited to a portfolio via the registrar, send an email notification to that user. Content for that email can be found in this document.
• When someone is invited to a portfolio via Django admin, send that same email notification to the user IF the user was added thru the "Portfolio invitations" table.
  • Do not send an email if the user was added thru the "User portfolio permissions" table
• If someone is added to a domain that's part of a portfolio—but the invited user isn't a member of that portfolio yet—they should receive this portfolio invitation AND a domain invitation.

Add static messaging in Django:

• Add a static message to the top of the "Add portfolio invitation" page that reads: "If you add someone to a portfolio here, it will trigger an invitation email when you click "save." If you don't want to trigger an email, use the User portfolio permissions table instead."
  • Link to the "User portfolio permissions" table in that message.
• Add a static message to the top of the "Add user portfolio permissions" page that reads: "If you add someone to a portfolio here, it will not trigger an invitation email. To trigger an email, use the Portfolio invitations table instead."
  • Link to the "Portfolio invitations" table in that message.
• Use slim blue alert, placed right below the heading on the "add" page for those tables.

Additional Context

Design the portfolio invitation email notifications so that they are not tightly coupled to a view, but rather reusable.
Probably best to do here: Refactor the user domain invitation email notifications so that they are not tightly coupled to a view, but rather reusable (match the portfolio invitation pattern) - this will be helpful for all follow-on email notification tickets.

These considerations add scope to the ticket and that warrants a repointing to 5 cc @lizpearl @abroddrick
