Secret Inbox1.5.4

Secret Inbox is the native companion app for managing your Fastmail masked email addresses on iPhone, iPad, and Mac.

Stop giving away your real email address. Create a unique masked email for every website, newsletter, or service you sign up for. When one gets spammed, simply block or delete it - your real inbox stays clean.

Create Emails Instantly
∙ Generate new masked emails with a single tap/click. Add custom domains and descriptions to stay organized. Copy any address to your clipboard and paste it wherever you need.

Manage Your Privacy
∙ View all your masked emails in one place. Block addresses that receive spam without deleting them. Bulk select and delete multiple emails at once when you're ready to clean house.

Built for Speed
∙ Lock Screen widget to copy emails without opening the app
∙ Siri Shortcuts: "Hey Siri, create a new masked email"
∙ Mac keyboard shortcuts for instant creation (customizable)
∙ Menu bar access on Mac for quick lookups

Search Your Mail
∙ Tap any masked email to search your Fastmail inbox for messages sent to that address. See exactly what's coming through.

Fully Accessible
∙ Complete VoiceOver support with descriptive labels, state announcements, and reduced motion options.

Your Data Stays Private
∙ Secure OAuth login directly with Fastmail. No third-party tracking. No data collection. Your credentials are stored safely in your device's keychain.

Requires a Fastmail account with masked email feature.
