Guidance for writing high-performing B2B marketing emails—covering subject lines, preview text, body copy, CTAs, and outbound messaging—to improve open rates, reply rates, and engagement.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Email Copy and Subject Lines ## Overview This skill covers best practices for writing B2B marketing emails that get opened, read, and acted on—including subject line construction, preview text, body copy structure, CTA language, outbound cold email, and common copy mistakes to avoid. All practices are sourced exclusively from Exit Five podcast guests; nothing has been added from general marketing knowledge. Where guests disagree, those disagreements are surfaced explicitly rather than resolved. --- ## The Email Chain: Optimizing Every Element in Sequence Treat email engagement as a chain where each element must pull the reader forward to the next. A break anywhere in the chain loses the reader. Optimize in this sequence: (1) from name/alias, (2) subject line, (3) preview text, (4) email headline, (5) body content. (Source: Jay Schwedelson, Episode #329) **From name:** - Send emails from a person's name (e.g., "Jen from Gong" or "Dave from Exit Five") rather than just the company name to create a direct, personal connection.

How to install
mdr add the-nam-shub/e5-real-skills/email-copy-and-subject-lines@sha256:0e1f4f63b6fce51cThe line at the top of this page pins the label v2026-04-21, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
