Yes but a screenshot is clearly not the best way to convey the information of an email. You cant search it, screen readers cant read the text, you cant zoom it properly if you have bad eyesight, etc…
Can screen readers still not read text in images? Years ago I could understand that being a problem, but now? If that's still true then it seems to me those screen readers could really use an upgrade. My phone has been able to copy text out of screenshots flawlessly for years.
I do agree with the overall point though that images are a suboptimal way of conveying text.

They shouldn't have to do OCR, a description of the image should be provided, there is even an attribute for that on the web, it's called "alt", or use picture/caption. Twitter and its shitty UI has no excuse.
Not entirely true. My blind friend encourages me to annotate screenshots whenever possible. It's just a pain, because you have to remember to do it as you tweet (you can't do it later), and only you can do it (why not crowdsource it?)
