SmartMail Expander makes Gmail threads easier to read by automatically expanding trimmed or hidden content in emails. Instead of clicking “Show trimmed content” every time, this extension reveals everything instantly — no interruptions. It formats older messages with clean indentation and customizable colors, making long email chains more readable and organized. Whether you're managing busy conversations, tracking replies, or just want a clearer view of your inbox, SmartMail Expander helps you save time and reduce email fatigue. With one-click control and a clean interface, it's a must-have for anyone who relies on Gmail daily.

no drama, works perfectly, and helps me see mails from Pubmed without having to click again. Thankyou!
Raf Vantongerloo
Doesn't work after Manifest V.
Paddy Landau
This extension does exactly as described. An extra benefit that's not mentioned in the description is that it also gets rid of that annoying email truncation, "[Message clipped] View entire message".
Barry Etheridge
Excellent replacement for the now deprecated Trimless. Every GMail user should get one!
