Allow and Deny Rules

Keep legit mail safe. Auto-engage certain senders without lifting a finger.

Allow rules (the safety net)

Allow rules guarantee Stringer will never engage with a matching sender, even if something somehow lands in stringer/queue.

Add allow rules for anything important: family, employer, bank, utilities, recurring vendors. Match by exact email, domain, or keyword in the subject/from line.

Examples

@your-employer.com — never touch work mail
grandma@gmail.com — never touch grandma
no-reply@stripe.com — never touch billing receipts

Deny rules (the auto-trap)

Deny rules automatically move matching messages into stringer/queue the moment they arrive. Good for senders you already know are scammers but who keep rotating domains.

Examples

@crypto-hot-deals-123.xyz — auto-engage domain
Subject contains URGENT INVOICE — auto-engage

Precedence

Allow rules always win. If a message matches both an allow rule and a deny rule, Stringer leaves it alone.

Managing rules

Rules live at Settings › Rules. You can enable, disable, edit, or delete any rule. Disabled rules are kept for quick re-enabling.
