Where can I see examples of dev portals built on Tyk Cloud?

Sorry, I don’t think the docs describe it all. I found answers to 1,2 and 5, but certainly not 3 and 4.
And they happen to be very important - #3 may cause developers typing a wrong email and they won’t know it happened. #4 is even worse - if you can’t make sure that emails won’t end up in SPAM - why allow to change the FROM email at all? It’s not something to be taken lightly. Here’s what I’m talking about - How to set up domain authentication | Twilio.
Alternatively you guys could allow us to plug in our own SendGrid or MailChimp into Tyk Cloud.

Also I don’t see how to change the FAVICON. It’s hardcoded.

Note that we’re on the Tyk Cloud subject, the on premises installation is not relevant for me at the moment.

Thanks in advance,
Anton.
