Segment sending identities

Give support replies their own subdomain with strict throttles while transactional confirmations keep a pristine IP. Marketing lives elsewhere entirely.

Route intelligently

Leverage SMTP relays that support rulesets based on headers or envelope sender. Auto-tag messages for CRM sync and analytics.
