Free email resources
Free email marketing resources in one place: field guides, articles, product news, checklists, templates, free tools, the pricing dataset, and the glossary.
Email guides
Five long-form guides to the parts of email that decide whether your mail lands. Each one anchors a cluster of shorter pieces.
Email guides and articles
Articles on deliverability, business email, newsletters, and outreach. Written from a mail system we run ourselves.
Product news
What we are shipping, what we are testing, and what the numbers behind it look like. Including the warm-up work in progress.
Free downloads
AI prompts for DNS setup, the pre-send gate, and the warm-up ramp, built from the rules we actually run, plus our pricing dataset as CSV and JSON.
Free email templates
Ten designed templates, five for the newsletter and five for regular mail, real HTML files free to download or copy into an AI agent.
Free email tools
Check any domain’s SPF, DKIM, DMARC and MX against live DNS, analyze raw email headers, build a DMARC record, and price fourteen providers.
Compare email providers
Head-to-heads, alternatives, and what fourteen providers actually charge, with the date we checked each number.
Email glossary
Thirty-five terms in plain English, each with the number that matters and where to read further.
How we work
Our sourcing rules, the no-affiliate policy, the AI-assistance disclosure, and how to tell us we got something wrong.
