Funnily enough, even for GMail I use their "legacy" HTML+URLs+POST requests interface. It's honestly a breath of fresh air (although the styling is a bit dated)

Funnily enough, even for GMail I use their "legacy" HTML+URLs+POST requests interface. It's honestly a breath of fresh air (although the styling is a bit dated). But it's lovely to be able to open multiple compose windows in new tabs by just middle-clicking the "Compose Mail" link. Then again, I realise the more explicit workflow is a matter of preference (eg it won't autosave drafts unless you hit "Save draft", and I like that, but others might not).
