Masked Email Manager
Do I need a Fastmail account?
Yes. Masked Email is a Fastmail feature and this app is a client for it. It does not work with Gmail, iCloud or anything else.
Where is my token stored?
In the app's own storage on your device. It goes to Fastmail's API and to no one else. There is no account with us and nothing to sync.
Can I choose what a new address looks like?
Partly. A prefix set in Settings starts every address you create in the app, followed by Fastmail's own random part. Addresses made through the Shortcuts action do not pick up the prefix.
Something is broken. Who do I tell?
Mail appfeedback@davidmohl.com. Support lists what to include.
