Gmail – Change email boxout text in Gmail

Currently still no, and probably never. The name that is displayed when you receive an email is the name embedded into that emails from:header. BUT there are two workarounds that I can think of, hopefully one will help you!

Use Filters

One workaround solution is to filter the email address and apply a label to it. This can help if their name is causing any confusion (eg. I have 4 people called Mike)

The Pros of using this is that it will sync across all your computers and devices.

Use a Script

There is a script called DisplayName gmail that takes the contacts name (the one you have set in your contacts list) and displays that instead of their from: name.

You will need to install tampermonkey (Chrome) or greasemonkey (Firefox) and then you can install the script DisplayName gmail (tested and working with chrome).

The cons of using a script is that its not going to work across multiple computers - you would need to install the script on each computer you use. And this also work on your phone.

You can enable the Inserting Images Lab.

I don't have an email client set up to test receiving inline images, but sending an inline image from another account with it enabled works fine.
