Mailbox type classification

Role-based email addresses: identify them without guessing

Understand generic inboxes such as info@, sales@ and support@, where they are useful and why some workflows treat them differently.

Practical ListCleaner guideReviewed October 2026

A role-based address represents a function or team rather than one named person. Familiar examples include info@, sales@, support@, billing@ and admin@. These addresses are not automatically invalid; many are important, actively monitored business inboxes.

Why teams classify role accounts

Ownership can change, several people may read the mailbox and consent or personalization assumptions can differ from a named contact. An outreach workflow may review them separately, while a customer-support or invoicing workflow may consider them ideal.

Separate classification from deliverability

“Role-based” describes the mailbox type. “Deliverable” describes the technical result. Keep those ideas separate so your product can accept a working support inbox while still recognizing it is not a personal address.

Recommended handling

  • Do not delete role accounts by default.
  • Define a policy for each use case.
  • Avoid personalizing a shared mailbox as though it were an individual.
  • Track engagement and complaints independently.
  • Honor opt-outs and suppressions regardless of mailbox type.
