Best of the inbox: the batch-and-blast tax

Best of the inbox: the batch-and-blast tax
Framing: mailing your whole list every send looks efficient and quietly trains Gmail to bulk-folder you. The curated cure:

🚀 Deliverability
— Engagement-tiered sending guide — earned its spot for the mechanic: mail your 30-day openers first, let their engagement vouch for the rest.
— The sunset policy template — picked because cutting 180-day dead weight raised inbox placement faster than any content tweak.

🧪 Tests
— Segmented vs. full-blast placement study — worth it for proving the same creative landed inbox for engaged, spam for cold.

📥 Swipe
— Re-engagement last-chance email — included as the polite off-ramp before you suppress.

Through-line: providers reward selective senders, not loud ones.
Saved you ~2 hours of wondering why your placement slipped.
