Seems like there's support for it in the Addon API.
Maybe someone with a bit of knowledge can do a refresh mail addon?
https://wiki.esoui.com/API#ingame.5Cmail
ZO_MailInbox_Gamepad:RefreshMailList()
Maybe can request in ESOUI?

Those loadscreens are always much quicker with the exception of CwC and Brass Fortress, which is some sort of hybrid of same zone / different zone, because it's on the same map but always takes the longer loadscreen. I'm betting that won't help, but I'll have to check it out.

Same zone Wayshrine to Wayshrine doesn't work for me.
The built in mail delivery delay is most annoying when you are crafting and run out of something. You can't run from the craft area in Vivec to the traders and just bye it. Better to Wayshrine to Alinor or Mournhold to bye and then Wayshrine back to Vivec to continue crafting.
