ユースケース

実用的な使い方： lessie-skill

Build a B2B prospect list for a sales sequence

👤 Founders, SDRs, agency owners running targeted outreach ⏱ ~45 min intermediate

使うタイミング： You need 50 qualified contacts for a specific campaign without a Sales Navigator seat.

フロー

Define the ICP

Use lessie-skill — find Engineering Managers at SaaS companies, 50-500 employees, using Stripe, HQ in EU.✓ コピーしました

→ Lessie find-people call with filter JSON, not generic search
Enrich contacts

Enrich the top 25 with verified email.✓ コピーしました

→ Emails plus validation status returned
Draft personalized emails

Draft individualized openers using each person's recent company news. No spam phrases.✓ コピーしました

→ Per-contact personalization, not copy-paste

結果： A usable prospect list with personalized opener drafts.

注意点

Treating 'verified' email as guaranteed deliverable — Warm your sending domain and monitor bounces — verification is probabilistic

組み合わせ： github

Source engineering candidates for a specific role

👤 Recruiters and hiring managers on small teams ⏱ ~30 min intermediate

使うタイミング： You need a shortlist before pinging a recruiter.

フロー

Search

lessie-skill — find Senior Rust engineers in Berlin or remote EU, with distributed systems background.✓ コピーしました

Qualify

→ Honest summaries, not just enrichment fields

結果： A human-readable shortlist ready for outreach.

ツール

このMCPが提供する機能

ツール	入力	呼び出すタイミング	コスト
find-people	title / company / domain / location filters	Starting from ICP filters	Lessie plan-dependent
enrich-contact	person id or profile	Shortlist narrowed and ready to contact	Per-enrichment credit
find-company	company name or domain + optional filters	Account research before outreach	Plan-dependent
send-email	Gmail/Outlook account + to/subject/body	Only after you review drafts — don't auto-send at scale	Uses your own mailbox

コストと制限

運用コスト

APIクォータ: Depends on Lessie plan — the skill itself is just the prompt wrapper
呼び出しあたりのトークン: Moderate; responses can be large when listing 50+ contacts
金額: Free — skills are local files. Lessie's data API is paid; consult current plans.
ヒント: Filter aggressively before enrichment; every enrichment call costs credits.

セキュリティ

権限、シークレット、影響範囲

認証情報の保管： Lessie API key in env var; Gmail/Outlook via OAuth if you use send-email

データ送信先： Queries go to Lessie's API. Email sending goes via your provider.

Contact enrichment must comply with GDPR / CAN-SPAM / local laws — Lessie provides data, compliance is on you.
Don't automate bulk sends without warming; volume without domain reputation = spam folder.

トラブルシューティング

よくあるエラーと対処法

Wrong trigger keywords — enrichment runs before filtering narrows the list

Explicitly: 'first find-people, then I'll pick who to enrich'.

代替案

lessie-skill 他との比較

代替案	代わりに使う場面	トレードオフ
Apollo.io / Clay	You want a full GTM suite with sequencing tools	Much heavier platforms; pricier
LinkedIn Sales Navigator	LinkedIn-native prospecting with InMail	Expensive, no agent integration
