What is the attachment limit for email?

Gmail and Outlook.com allow about 20 to 25 MB per message, and many company mail servers allow only 10 MB. Encoding adds roughly a third to the size in transit, so aiming for 10 MB keeps you safely under most limits.

Will my text still be selectable?

If the file reaches the target with structural optimization alone, text, links, and forms are kept. If pages have to be re-encoded as images to get smaller, the text is no longer selectable. The result message tells you which happened.
