Anonymous mode
The default. Maski receives a message, holds it briefly, forwards it to your destination, and keeps nothing. There is no stored copy and no inbox to manage. Anonymous mode still honours blocking. Block a sender, or add a rule that blocks a pattern, and matching mail is dropped silently. Rules that would hold or route mail collapse to a plain forward, because anonymous mode never retains anything. Use anonymous mode when you just want a maskable address that forwards and forgets.Control mode
Available on Pro. Control mode adds per-sender rules and a held inbox, so you decide what happens to each message instead of forwarding everything.Per-sender rules
A rule matches a sender and chooses an action:- Forward — send it to your destination.
- Block — drop it silently.
- Hold in inbox — keep it in a dashboard inbox instead of forwarding, with an optional expiry.
bob@example.com, or a domain wildcard,
*@example.com. Rules are evaluated in priority order and the first match wins, so
put your most specific rules first. Reorder them by dragging in the dashboard.
Each alias also has a default action for mail that matches no rule, normally
forward. A Pro alias can flip the default to hold everything, which makes
forwarding an explicit per-sender choice.
Held inbox
Mail held by a rule lands in a per-alias inbox in the dashboard. New messages appear in real time. You read, release to your destination, or delete them, and anything you leave expires automatically after its retention window (7 days by default, adjustable from 1 to 30).One hold happens on every plan, including free. If your destination keeps bouncing,
Maski pauses forwarding and holds incoming mail so nothing is lost while you fix the
address. Rule-driven holds remain a Pro feature.
Choosing a mode
Use anonymous mode
You want a throwaway-friendly address that forwards and retains nothing.
