SquadMail, dubbed the "Dropbox of email", syncs and shares email folders between different users. The service now has a cool new feature for both individuals and groups: automatic saving of email attachments to Dropbox.
SquadMail's Dropbox saving feature works just like its core email syncing service. After setting up a new folder on the SquadMail site and choosing to sync it with Dropbox, SquadMail creates a new label for your email account (Gmail or other IMAP email) with the name of that folder. Then, to have attachments for emails saved to Dropbox, all you have to do is tag emails with that label.
With filtering, you can automate saving attachments to Dropbox. So, for example, you can create a filter for friends and family with the "has:attachment" option in Gmail and always tag it with your Dropbox folder label. Voila, all the photos and other docs from them are automatically saved there.
You can also forward emails to the SquadMail-provided email address for that folder. I found this to work immediately, whereas the label method can take a few minutes for the sync to happen.
Finally, anyone you share that SquadMail folder with, as before, will also have that folder and any messages in it in his/her email account.
The Dropbox feature is in private beta right now, but the first 5000 Lifehacker readers can try it out today using the link below.
