> Unlike most email clients, Vivaldi Mail does [...]– automatically detecting mailing lists and mail threads, as well as offering a powerful search feature. What are these mail clients that don't do threads or have search? The only mail client I've encountered in the last 10 years without threading was the mobile ProtonMail client. Also, every point in that list is either of questionable value (if I've already selected the text, there's not huge barrier to just pasting it in an email manually) or applies to all email clients running in a browser. The only advantage I can think of for having an integrated browser/mail client is not needing a pinned tabbed to always have email notifications when the browser is open, and funnily enough it's not even mentioned in the article.
