<b>Cold outreach vs opt-in sending: don't mix the playbooks</b>
The reads that keep cold tactics from torching your real list.

🚀 Deliverability
— Separate-domain cold-email guides — never run cold outreach on your money domain; burn a throwaway, protect the asset.
— GMass / Instantly sending-limit docs — the daily caps and ramp that keep cold sends under Gmail's radar.
— Spam-complaint law primers (CAN-SPAM / GDPR basics) — cold and opt-in carry different legal and reputational risk; know which you're running.
— Inbox-rotation and deliverability-pool writeups — why cold senders rotate inboxes and why opt-in senders shouldn't need to.

Made the cut because the most common blow-up is applying cold-email volume logic to a permission list, or vice versa.

Saved you ~2 hours and possibly your main sending domain.
