19 things Microsoft & Google will throttle or block you for in 2026 — and the exact fix for each. Most senders burn out by Q3 doing the opposite. Run this before your next send.

A few of the 19
- 1.Sending cold email from your primary domain — and why it burns the business.
- 2.The 0.3% complaint ceiling that quietly retires sending domains.
- 3.Why warmup + inbox rotation is theater — and the lever that actually works.
- 4.Microsoft scores the mailbox now, not the domain. What that changes.
The few who last in 2026 don't send more — they run outbound on discipline.
That's exactly what 1OAKS is built on.
