I have a number of older emails in Gmail which are unread which I'd like to make read but I don't want to mark recent unread emails as read. Can I mark all emails from a specific date to be marked read without manually finding each one?
The same way you'd do any bulk action on email messages: Search first.
Assuming you want to find all of the messages from before April 1 and mark them read:
- search Gmail for
- click the checkbox at the top of the list to select all of the visible messages
- if you have more than 1 page of results, you'll get a message similar to "All 50 conversations on this page are selected. Select all conversations that match this search" where "Select all conversations..." is a link. Click that link to choose all matching messages
- Choose your action. "Mark as read" should be one of the buttons at the top, among others. There are other actions in the "More" menu
There are a lot of search operators you can use with Gmail.
