How can hybrid routing protect main brand reputation?

Hybrid routing strategy:

Main brand protection:

Reserve main domain for lowest-risk mail

Transactional and highly engaged only

Conservative practices always

Isolated routing for risk:

Marketing campaigns on subdomain or separate domain

Reactivation attempts on isolated infrastructure

Cold outreach on completely separate domain

Benefits:

Main brand reputation protected

Risky activities do not contaminate valuable assets

Can be more aggressive on isolated domains

Management:

Clear rules for what goes where

Monitoring per stream

Quick isolation if problems emerge
