I’ve just been listening to a wonderful presentation at emailexpert’s Inbox Expo, given by Chamaileon /’s Roland Pokornyik and Patricia Blesa. It has to do with accessibility in email design.
I work with a severely visually impaired person and my dad is one too, so while I don’t have any immediate personal experience of the topic yet, thankfully, I see the effects up close. The tips from Patricia and Roland are pure gold for anyone who is trying to serve all readers of their emails.
