Shared SaaS tracking domain vs your own dedicated domain

Voluum-style shared domains vs a custom one you register. The tradeoff is convenience vs deliverability control.

Use the shared/default tracker domain when:
— You're testing a new offer for a day and don't want DNS setup.
— Volume is low and the source doesn't inspect domains.

Use a dedicated custom domain when:
— You're scaling — shared domains get burned by other users' bad traffic.
— The traffic source checks domain reputation at review.
— You need full control of SSL, DNS TTL, and rotation.

Tradeoffs to record:
— Shared = zero setup but you inherit every other operator's blocklist hits.
— Dedicated = you own your reputation but you maintain certs and warm-up.
— A shared domain flagged by someone else can kill your live campaign overnight with no warning.

Rule: never scale paid spend on a shared tracking domain. Move to dedicated before you cross meaningful daily budget, and keep TTL low for fast rotation.

Save this SOP. Run this before every launch.
