Private email. Simplified.
Skiff Mail is end-to-end encrypted email that protects your inbox and gives you the power to communicate freely.

Your inbox. Now yours.
We keep our lives in our inboxes. Skiff Mail’s end-to-end encryption keeps your mail private and secure. No one — not big tech, not us, not anyone — has access but you.

Completely open source.
Privacy is more than a promise. Skiff Mail has been open source since day one so that our privacy claims and encryption protocols can be verified by anyone.
Communicate and collaborate. All in one place.
Your Skiff Mail account gives you access to the first-ever end-to-end encrypted productivity suite. Jump from docs to email, to remote collaboration with your team. And never compromise your privacy in the process.

Fast. Free. Search.
Search is a must-have. But other private email providers offer it only to paid users. Every Skiff Mail user gets access to blazing-fast, secure search for the full contents of their emails. Searches are carried out client-side (on your device), so end-to-end encryption remains intact.

Everything you expect. And more.
10 GB Free Storage
Skiff Mail offers more free storage than any other end-to-end encrypted email service.
