Allowlist is the modern term for a list of approved senders, domains, or IPs.
Whitelist vs Allowlist explains the shift toward clearer, modern terminology. In email operations, an allowlist is a list of approved senders, domains, or IPs that should bypass certain filters or receive special routing. Many tools still say “whitelist,” but “allowlist” is increasingly preferred in product UI and documentation. For a productivity platform, allowlisting can be used for VIP senders, internal domains, or critical system emails. It’s best paired with clear rules so it doesn’t accidentally override important safety checks.
