marketingskills / cold-email (Corey Haines)
Leading#1 in Skillshigh confidence
The de-facto leader for the cold-outreach craft: a SKILL.md that writes B2B cold emails and multi-touch follow-up sequences (subject lines, openers, CTAs, cadence). Lives in the most-adopted marketing Agent Skills repo (~41.5k stars). Writes copy — does not send.Our read
Why it ranks #1
The cold-email skill sits in the category's dominant marketing Agent Skills repository at roughly 42k GitHub stars, giving it far more adoption and citation than any dedicated outreach prompt bundle.Here is the catch
writes copy but does not find leads, send mail or track replies
repository-level stars do not measure this skill independently
generated claims and personalization still require human review
Does this well
clear, practical craft guidance from a widely adopted repository
covers full sequences rather than one-off messages
vendor-neutral and easy to customize
