About
Folio is the inbox for one person running many businesses. Every custom domain on your Folio account arrives in one reading view, color-striped down the margin so you always know which business a letter belongs to.
This free app is the iPhone companion to your Folio account. Sign in with the email address on your account; there is no password to leak, reset, or reuse.
ONE INBOX, MANY DOMAINS
Mail for all of your domains lands in a single unified inbox. A stable color stripe per domain keeps each business separate without juggling apps or accounts.
REPLY AS THE RIGHT BUSINESS
Folio picks the correct From address for every reply, so a letter to your consulting client never goes out under your product domain.
ANTI-SPOOFING BUILT IN
Folio checks SPF, DKIM, and DMARC on every incoming message and files mail that fails authentication to spam, with the reason explained in plain English.
NEW-MAIL NOTIFICATIONS
Get a notification on your iPhone when a new letter arrives.
CALENDAR INCLUDED
Your calendar lives in the same account and the same app.
SIGN IN WITH A PASSKEY OR A CODE
Use Face ID with a passkey, or a one-time code sent to your email.
Built for portfolio entrepreneurs, solo founders, multi-LLC owners, consultants with a product, and the holding company of one.
