How should marketing, transactional, and cold emails be separated?
Transactional (highest protection):
- Own subdomain (e.g., notify.tidalmail.com)
- Dedicated IP if volume supports
- Most conservative practices
- Never mixed with bulk marketing
Marketing:
- Own subdomain (e.g., news.tidalmail.com)
- Can share IP pool with other marketing
- Engagement-based sending practices
- Isolated from transactional
Cold outreach (highest isolation):
- Completely separate subdomain
- Separate IP
- May need separate root domain
- Highest risk, needs maximum isolation
- Protect your most valuable streams from your riskiest.
- Essential cargo on clean ships. Experimental cargo on isolated vessels.
