## Studies and playbooks

- [Every placement test we ran on prewarmed inboxes](https://warminboxes.com/research/inbox-placement-log)Every new batch of prewarmed inboxes is seed-tested before it ships, and only stock clearing 95% is deployed. Seven tests, 333,731 messages scored, published whole — a live read on how hard inboxing got through 2026. Every results screen is on the page.
- [A study of top-level domains by sends](https://warminboxes.com/research/google-sender-reputation)3,415,449 sends split across five TLDs and scored against Google’s permanent domain-reputation verdict. .link drew it 16 times more often than .com, and .org twice as often — and the gap holds inside a single client, where the copy and the list are the same. The TLD you buy predicts this better than anything else we measured, and unlike a blocklist listing it costs replies.
- [Does a SURBL listing actually hurt cold email? We tested 2,817 sending domains](https://warminboxes.com/research/surbl-blocklist-study)A DNS sweep of every live sending domain, not a sample. 43.3% were listed, and reply rate barely moved: 1.14% to 1.16%. Includes the three mechanisms we diagnosed SURBL grouping domains on — shared keyword, redirects to one master, shared nameserver zones — and the fix for each.
- [The 2026 Inboxing Playbook](https://warminboxes.com/inboxing-playbook)A clean operator guide for building cold email infrastructure that survives longer, routes smarter, and keeps campaigns out of spam.
- [The Ultimate Liquid Syntax Guide: Hidden Ways To Personalize Cold Emails Using Your Sequencer](https://warminboxes.com/playbooks/liquid-syntax-guide)How to make cold emails feel timely, human, and relevant at scale with Liquid syntax, smarter conditional logic, and better sending context.
- [How to Avoid the SPAM Plague in 2026: The Complete List Verification, ESP, ESG & Role Segmentation Playbook](https://warminboxes.com/playbooks/spam-plague-segmentation-playbook)A field-tested cold email segmentation system for cleaner lists, better inbox routing, sharper persona-based copy, and higher reply rates before you ever launch.

## The free tools

Every deliverability check the agency runs before a campaign is public and free on this site, and callable by an agent through the MCP server. They state what they cannot see rather than inventing a score.
