What it does

When installed, the agent writes B2B cold emails, follow-up sequences, LinkedIn connection messages and multichannel outreach plans that aim to sound like a thoughtful peer rather than a sales template. It also gives guidance on subject lines, personalization, reply handling and email deliverability such as using secondary sending domains, verifying lists, and disabling open tracking. The skill is mostly written guidance in SKILL.md and reference files; it does not itself send any email.

Great for

  • Founders or sales reps writing their first outbound campaign
  • SDRs who need follow-up sequences and reply-handling copy
  • Marketers planning a combined email, LinkedIn and phone cadence

Skip it if

  • Sending bulk unsolicited email without consent, which can breach anti-spam laws and damage sender reputation; the skill advises opt-out lines but does not handle legal compliance
  • Lifecycle or newsletter email to existing customers, which the skill says belongs to a different skill (emails)

Try asking

  • “Write a three-email cold sequence to heads of ops at mid-sized logistics companies”
  • “My cold emails get no replies; rewrite my opening line using this observation about their recent funding”
  • “Draft a LinkedIn connection request and follow-up message for SaaS founders”
  • “Write a breakup email for a prospect who has gone silent after four touches”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Give the agent a specific prospect signal (funding, hiring, a LinkedIn post) so personalization has something real to connect to.
  • Ask the agent to check your draft against the listed AI-tell phrases and keep only one call to action per email.
  • Set up SPF, DKIM and DMARC and warm mailboxes before sending; the deliverability reference covers the thresholds.
