Attachments.me is one of my favorite services, as it really does a great job of wrangling all of those attachments in my various Gmail accounts.
Here’s what it looks like:
With the Attachments.me plugin, all of the options to share files are shown right within the Gmail UI. There’s no need to load other apps and pull in outside links, it’s all right there for you.
The service tells us that it now has over 50K users, which is pretty impressive considering how niche it is.
