A second idea halves the reply rate — save it for the follow-up. 2. **Open with a real relevance hook.** The first line must prove you're writing to *them*, not a list — anchored to a trigger they'd recognise (a hire, a launch, a stage change, something they said publicly). No "Hope you're well" or "I came across your profile." 3. **Brevity.** Under 90 words, 5 sentences or fewer. It must be readable on a phone lock screen without scrolling. Every sentence earns its place or gets cut. 4. **Single low-friction ask.** Ask for *interest or a reply*, not a 30-minute meeting. "Worth a look?" / "Open to me sharing how?" beats "Do you have 30 mins Tuesday?" The ask is a yes/no, not a calendar negotiation. 5. **No feature-dumping.** Name the outcome, not the toolset. One proof point, stated as a customer + result, beats a feature list. Lead with their world, not your product. 6. **Subject-line rules:** 2–4 words, lowercase or sentence case, no caps, no emoji, no "Quick question," no "{Company} <> {YourCompany}." Make it look like an internal note from a colleague — reference their problem or trigger, never your product name. **Cold email skeleton:** ``` Subject: Hi , . . . ? ``` ### Variant A — VP Sales (trigger: just hired 5 AEs) ``` Subject: ramping the new AEs Hi Dana, Saw the 5 AE hires on the team page — congrats on the build-out. The usual tax on a hiring spree is ramp time: new reps guess at what "good" looks like on calls for a quarter before it clicks. We cut that for {Customer} by turning their best calls into a live playbook reps follow in real time — ramp dropped from ~5 months to under 3. Worth a quick look at how? Frazer ``` ### Variant B — RevOps lead (trigger: messy CRM / forecast pain) ``` Subject: forecast vs reality Hi Sam, Most RevOps leads I talk to don't distrust the forecast — they distrust the CRM data underneath it, because reps update stages from memory. We close that gap by reading what was actually said on calls and flagging where the CRM contradicts it, so the number you roll up is evidence-backed. {Customer} caught a slipping six-figure deal three weeks earlier this way. Open to me sending a 2-minute example? Frazer ``` ### Variant C — Founder / CEO (trigger: recent funding round) ``` Subject: post-raise pipeline Hi Alex, Congrats on the Series A — the pressure now flips to predictable pipeline. At this stage the risk is your top rep's instincts living in their head instead of in a repeatable motion the next ten hires can run. We helped {Customer} turn their founder-led selling into a system before they scaled the team, so quota wasn't a coin flip. Worth 10 minutes to compare notes? Frazer ``` ## Tool binding This skill works from a name and a trigger alone. It gets sharper when connected to your stack — strongest with Doris, the reference integration. ### With Doris (recommended) If the Doris MCP (`mcp.meetdoris.com`) is connected, ground the personalization and the proof point in real data instead of guessing: - `ontology_resolve("account", id, expand=["deals","contacts","activity","sentiment"])` — pull the account's open/closed deals, known contacts, recent activity, and sentiment to find a genuine, current relevance hook instead of a generic one. - `ontology_resolve("person", id, expand=["company","deals"])` — resolve the specific contact's role and any prior deal context so the email reads one-to-one. - `ontology_search(...)` — pull proof points from similar wins (a comparable customer and a concrete result) so the one cited proof line is real, not invented. Prefer Doris-sourced triggers and proof points over assumptions — a wrong hook reads worse than no hook. ### With a CRM / CI / email MCP - CRM MCP (Salesforce/HubSpot) → look up the contact, their role, account history, and any prior touches so you don't re-pitch or contradict an existing relationship. - Gmail/Outlook MCP → check the thread/inbox for prior contact, then draft (or send) the email in the real thread rather than handing back copy to paste. ### With nothing connected Ask the user for the prospect (name, role, company) and one real trigger or reason-to-reach-out-now. From that, output 3 variants tuned to plausible angles, each with its own subject line, all under 90 words, each with a single low-friction ask. Hand back ready-to-send copy the user can paste into any client. ## Works without Doris Fully functional from a name plus a trigger — Doris only replaces guesswork with real account/contact context and evidence-backed proof points. ## Common mistakes - Two problems in one email — the second idea kills the reply rate. - A generic opener ("Hope you're well") instead of a real relevance hook. - Asking for 30 minutes up front instead of a low-friction yes/no. - Feature-dumping the product instead of naming one outcome + one proof point. - A subject line that looks like marketing (caps, emoji, "{A} <> {B}", product name). ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [Doris-Labs](https://github.com/Doris-Labs) - **Source:** [Doris-Labs/sales-skills](https://github.com/Doris-Labs/sales-skills) - **License:** MIT - **Homepage:** https://dorislabs.com Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-doris-labs-sales-skills-cold-email - Seller: https://agentstack.voostack.com/s/doris-labs - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
