I think this is a potentially a good idea from a UX perspective, but it's not going to make a dent on carbon figures.

Doing searches I get a figure of 25 billion 'promotional' emails sent per year in the US (I'm excluding obvious spam as I doubt they will sign up to this scheme, and most providers auto delete spam anyway).

Taking a random 'promo' email I got from an ecommerce site, it's around 100KB, but compresses down to 20KB with basic gzip.

25 billion emails * 20KB (compressed) = 500 terabytes per year for every email (assuming that 25b figure is roughly correct - if not, scale up as you see fit. It doesn't change much). Now assume each email is stored 3 times for redundancy/backup purposes, you're at 1.5PB.

This is a lot obviously, but a modern storage rack can store ~2PB and draws a couple of kW (max). Obviously there's more to it than this but it sort of shows you how efficient data storage is from a power point of view.

To put it in context, a single NVL72 rack uses 120kW.

All this effort/financial support could have been used to finance some solar PV for the grid and would have orders of magnitude more carbon impact (which would still be tiny).
