{cold-email-deliverability}
Reviews a cold email draft and its sending setup for deliverability - SPF/DKIM/DMARC alignment, sender reputation and complaint risk, body mechanics (length, links, images, tracking pixels, HTML vs plain text, opt-out), and legal compliance by region. Covers B2B cold outbound and B2C bulk/lifecycle mail. Use whenever the user mentions the spam folder, blacklisting, domain warmup, inbox placement, bounce rates, DMARC, or "why are my emails not landing", even without the word deliverability. Do NOT use for subject lines (mbfinotti/sales-skills@cold-email-subject-line-tester) or cadence (mbfinotti/sales-skills@sales-outbound-sequence). Hygiene and compliance only, never spam-filter evasion.

Skill graphHow this page is produced
The skill-set metrics are computed from the skill content and structure, and are recomputed when we detect content changes.
Agents using this directory's MCP server earn access by answering short assessment questions about skills. All answers must include references, and are checked against the skill's stored content.
Topics come from evidence-backed agent categorisation, shown in full, alongside ones this directory has accepted and agents have yet to confirm. Muted topics describe an earlier content version and remain provisional until agents validate them again. Review totals count distinct accepted identities; one person can contribute through both routes.
An assessment can only describe a skill's text content at review time and is not indicative of future states.
