Two suggestions: First, replace the word "Messages" with either "email" or "mail" on all webpages and across all platforms because most users associate the word "messages" with text messages. Second, standardize the icon, appearance and wording for the INBOX, DRAFT, SENT, TRASH, etc. across all webpages and platforms for consistency. As an example the icon and text that shows in the Proton Mac version is different than what is shown in the iPad version. Again, make it consistent.
