Commentary: Email Authentication and QA Tool Development
10 September 2025
We've got some focused and niche updates this week. ARC still has experimental status with the IEFT (RFC history here) but Zendesk handles a huge quantity of email so implementing features seen in the wild is important.
It's feeling like Zendesk QA (FKA Klaus) is not a priority. A long time ago I did a QA implementation project and evaluated a bunch of tools and I'm sure the competition aren't sitting still. The Tallinn office are recruiting engineers (see) so we will be keeping a close eye on the future of this product.
Tangential but I wrote some notes on the design of the gradients you see on this page and there's a demo gradient comparison tool if you want to play!
