Smart and simple filtering

Our algorithms determine the importance of each email, move unimportant messages out of the Inbox into a separate folder, and summarize them for you. Now you can focus on what's important.

SaneBox works anywhere you read your email

SaneBox works anywhere you read your email - Gmail, Exchange, Yahoo, AOL, Apple Mail, Outlook, iPhone, Android etc. There's nothing to install or download, we just add a folder to your email!


SaneNoReplies is a folder that keeps track of emails you have sent that have not been replied to yet. It’s a bulletproof follow up process that ensures important threads don’t fall through the cracks.


Search any domain name to find colleagues who have relationships at that company, then request an intro with one click. (SaneBox for Business feature)

SaneBlackHole unsubscribe

Drag an email into the SaneBlackHole folder, and you'll never hear from that sender again (it goes straight to trash). Unsubscribe from mailing lists with 1 click!

Follow-up reminders

We will notify you when an email you sent was not replied to by a certain time, so you can follow up on it. It's also a great way to send an email reminder to your future self.

$5 for you and $5 for your friend

Do you like your friends? Invite them to SaneBox. Every friend who signs up for a trial from your invitation will get a $5 credit and so will you. That's what you call Instant Karma.


Once a day (or more often if you want) we'll send you a powerful summary of your activity. You can view and process your latest unimportant emails, upcoming reminders, and more right from the SaneDigest.

Unbelievable customer service

We don't sell products - we make happy customers. We want you to love your email, and won't stop until you are completely satisfied with it.

Executive Assistant Access

Let your assistant receive your SaneBox Digest, so they can process your unimportant email for you.


Vacation is not for checking email. It's for drinking mojitos on the beach. Snooze emails until your vacation is over and enjoy your mojito without feeling guilty.

Move attachments into the cloud

Attachments are hard to find and take up lots of storage space in your email. Sane Attachments scans emails in your Inbox for attachments, puts them on Dropbox, and replaces them with a link.

Social network refinement

Although SaneBox has impressive accuracy out of the box (and needs no training), you can make it even smarter by connecting to your social networks (Facebook, LinkedIn and Twitter).


Messages trained to a SaneFwd folder are forwarded to Evernote, Expensify, or pretty much whomever you want.
