Provide MailChimp with a custom From Email domain (but which domain?)

MailChimp warns us about the following:

Deliverability warning
The From email address for this campaign is set as gitrevnews@gmail.com.
In the near future, Gmail will implement authentication policies that could prevent your campaign from being delivered to Gmail addresses.

Sounds like some spam prevention effort. The right thing for us to do would be to have something like feedback@gitrevnews.com - in any case, whatever From-email we specify, we'll have to verify the domain (I'm guessing we have to have a valid email there) with MailChimp.

Any ideas what domain we could use, @chriscool ? I only own tfnico.com and gitminutes.com. I could set up a forwarder on revnews@gitminutes.com to go to our gmail account, but it's still a bit weird.

Comece com o aviso de entregabilidade do MailChimp citado na issue e analise os endereços de remetente propostos e os domínios disponíveis. Confirme qual domínio e qual endereço From devem ser usados e, em seguida, verifique se o domínio selecionado foi configurado com sucesso no MailChimp.
