How to use the Cold Email Writing agent skill

What the cold-email skill makes the agent do

Once installed, the agent writes B2B cold emails and follow-up sequences, LinkedIn connection messages and multichannel outreach plans. The goal of the copy is to sound like a thoughtful peer rather than a sales template. The skill also gives guidance on subject lines, personalization, reply handling and email deliverability.

The skill is mostly written guidance in SKILL.md and reference files. It does not send any email itself. You copy the output and send it through your own tools.

• Cold emails built around an observation, a problem, proof and one low-friction ask
• Follow-up sequences where each email adds something new
• LinkedIn connection and message copy
• Multichannel plans that combine email, LinkedIn, calls and other channels
• Guidance on sending setup, list verification, tracking and reply handling

Install the cold-email skill

Download the ZIP for the cold-email skill from our page. Then choose one of the two install locations below.

For a personal install that works across your projects, unzip the folder into ~/.claude/skills/. To limit it to one project, unzip it into that project's .claude/skills/ folder.

If you use the Claude apps instead, open Settings, go to Capabilities, then Skills, and upload the skill there.

• Personal install: ~/.claude/skills/
• Project install: the .claude/skills/ folder inside your project
• Claude apps: Settings → Capabilities → Skills, then upload

Trigger the skill with natural requests

You do not need a special command. The skill is meant to activate when your request matches its trigger phrases. These include 'cold email', 'cold outreach', 'follow-up sequence', 'SDR emails', 'LinkedIn outreach', 'connection request message', 'cadence', 'voicemail', 'handle replies', 'email deliverability', 'sending domains' and 'warm up inboxes'.

The more context you give, the better the result. The skill's own guidance says to provide who you are writing to, what outcome you want, the specific value you offer, any proof you have and any research signals such as funding, hiring or company news. If you leave some out, the agent can still write, and it will note what would make the copy stronger.

• Write a 3-email cold sequence to heads of ops at mid-sized logistics firms. Our proof is a case study that cut invoice errors.
• Nobody is replying to my outreach. Review this sequence and tell me what to change.
• Write a LinkedIn connection request for a VP of Engineering who just posted about hiring.
• Plan a multichannel cadence of email, LinkedIn and a call for a product-led SaaS trial list.

Examples of useful requests

Good requests name the audience, the goal and any signal you have. The skill is built to avoid AI tells such as 'it's not X, it's Y' reveals, and it favours short copy with one ask.

For list building and account research, the source says to use the prospecting skill. For lifecycle email to existing customers, use the emails skill. For call scripts and sales collateral, use the sales-enablement skill.

• Subject line options for a first outbound email, with 2-4 words in lowercase
• A breakup email for a prospect who has ignored four touches
• Reply-handling copy for an information request and a not-now reply
• Opt-out line and postal address placement for an outbound email

Safety notes: scripts and network

According to the skill's listing, it runs no scripts and uses no network access. It requires nothing else to be listed. Its files are markdown and JSON reference material.

The skill does not handle legal compliance. It advises an opt-out line and your postal address, but bulk unsolicited email without consent can breach anti-spam laws and damage sender reputation. Check the rules that apply to your recipients before you send anything the agent writes.

• Runs scripts: no
• Uses network: no
• Requires: nothing listed
• Licence: MIT

Tips for getting value from the skill

Before the first send, the skill recommends sending from secondary domains rather than your primary one, setting up SPF, DKIM and DMARC, warming mailboxes, verifying every list right before upload and keeping bounces under 2%. It also recommends turning off open and click tracking and measuring replies instead.

In multichannel campaigns, a reply on any channel should stop all of them. Read the deliverability and reply-handling reference files when you need the detail.

• Read your draft aloud. If it sounds like marketing copy, ask for a rewrite.
• Remove the personalized opening. If the email still makes sense, the personalization is not working.
• Ask for one ask per email, phrased as an interest-based question.
• Check every email for the opt-out line and postal address before sending.
