Push GitHub Leads to Lemlist: Multi-Channel Sequences Powered by GitHub Signals

Lemlist is a multi-channel outreach platform known for personalized image and video thumbnails, LinkedIn step automation, and warm deliverability. GitLeads captures developer buying signals from GitHub in real time — new stars on tracked repos, keyword mentions in issues and PRs. Connecting them means every developer who signals intent on GitHub can automatically enter a Lemlist campaign with context-rich personalization data baked in.

Why GitHub Signals Make Lemlist Sequences Actually Personal

Lemlist's differentiator is personalization at scale — custom images, introductory lines, and variable-driven copy. But personalization only works if you have something real to personalize with. "I noticed you work in software engineering" is not personalization. "I saw you starred the LangChain repo — guessing you're building something with LLMs" is. GitHub signals give you the real trigger. Lemlist gives you the delivery infrastructure.

• Stargazer signal → reference the repo they starred in your first image/line
• Keyword mention → reference the specific problem they described in the issue
• Fork signal → note they're actively building with a related project
• Top language from GitHub profile → tailor technical copy to their stack

Integration Architecture: GitLeads → Lemlist

GitLeads sends enriched lead data via webhook on every new signal. Lemlist exposes a REST API to add leads to campaigns. The integration is a lightweight webhook handler — either a serverless function or a no-code tool like Make, n8n, or Zapier.

// Webhook handler: GitLeads → Lemlist
// Deploy as a Vercel/Cloudflare/Railway serverless function

export async function POST(req) {
  const lead = await req.json();

  if (!lead.email) return new Response('skipped');

  // Choose campaign by signal type
  const campaignId = {
    stargazer: process.env.LEMLIST_STARGAZER_CAMPAIGN_ID,
    keyword:   process.env.LEMLIST_KEYWORD_CAMPAIGN_ID,
    fork:      process.env.LEMLIST_FORK_CAMPAIGN_ID,
  }[lead.signalType] ?? process.env.LEMLIST_STARGAZER_CAMPAIGN_ID;

  const res = await fetch(
    `https://api.lemlist.com/api/campaigns/${campaignId}/leads/${lead.email}`,
    {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
        Authorization: 'Basic ' + btoa(':' + process.env.LEMLIST_API_KEY),
      },
      body: JSON.stringify({
        firstName:      lead.name?.split(' ')[0] ?? lead.username,
        lastName:       lead.name?.split(' ').slice(1).join(' ') ?? '',
        companyName:    lead.company ?? '',
        // Lemlist custom variables — use in {{variable}} syntax in sequences
        githubUsername: lead.username,
        signalContext:  lead.signalContext,   // "starred vercel/next.js"
        topLanguage:    lead.topLanguages?.[0] ?? '',
        location:       lead.location ?? '',
        bio:            lead.bio ?? '',
        followers:      String(lead.followers ?? 0),
      }),
    }
  );

  return res.ok ? new Response('ok') : new Response('error', { status: 500 });
}

No-Code Setup via Make (Recommended)

Make (formerly Integromat) has a native Lemlist module that simplifies the setup significantly. No custom webhook handler required:

1. GitLeads → Integrations → Webhook → copy your webhook endpoint URL
2. Make → New scenario → Webhooks → Custom webhook (trigger)
3. Add a filter module: only continue if {{lead.email}} is not empty
4. Add a Lemlist module: "Add Lead to Campaign" — connect your Lemlist account
5. Map fields: firstName from lead.name, custom variables from signalContext, topLanguages, location
6. Set campaign: use the campaign ID for the signal type (stargazer vs keyword)
7. Test by starring one of your tracked repos — the lead should appear in Lemlist within 60 seconds

Using GitHub Signal Context in Lemlist Personalized Images

Lemlist's signature feature is dynamic images — screenshots with text overlays personalized per recipient. The signal context GitLeads captures maps directly to this:

• Background image: your product UI or a relevant screenshot
• Text overlay variable 1: {{firstName}} — from GitLeads name field
• Text overlay variable 2: {{signalContext}} — e.g. "starred prometheus/prometheus"
• Result: a personalized image that says "Alex — saw you starred prometheus/prometheus"

Lemlist sequence for GitHub stargazer leads:

Email Step 1 — Day 0:
Subject: {{firstName}} — you starred {{repoName}}

[Personalized image: your product + "{{firstName}}, noticed you starred {{repoName}}"]

Hi {{firstName}},

Saw you starred {{signalContext}} — if you're evaluating [your category],
[one-sentence pitch on what you do differently].

[Social proof line — customer + outcome.]

Worth a 15-minute look?

LinkedIn Step — Day 2:
Visit profile → connect with note referencing the same signal context.

Email Step 2 — Day 4:
Subject: Re: quick follow-up

Following up on my last note. Happy to show you [specific use case
relevant to {{topLanguage}} or {{signalContext}}].

Email Step 3 — Day 9:
Subject: Last one from me

LinkedIn Steps with GitHub Context

Lemlist supports LinkedIn connection request and message steps. GitHub profiles often link directly to the developer's LinkedIn. GitLeads surfaces the GitHub profile URL; from there you can cross-reference LinkedIn. For high-value keyword signals (e.g., a developer asking about your exact use case in a GitHub issue), adding a LinkedIn step after email Step 1 meaningfully increases response rate.

Lemlist vs Instantly vs Smartlead for GitHub Lead Sequences

All three tools work well with GitLeads. Lemlist wins if you want LinkedIn steps and personalized image/video thumbnails — it's the most multi-channel of the three. Instantly wins on deliverability infrastructure and price at high volume. Smartlead wins for teams that want AI sequence generation and advanced inbox rotation. GitLeads integrates identically with all three via webhook.

Enriched Fields GitLeads Sends to Lemlist

• email, name, GitHub username, profileUrl
• company, location, bio — from GitHub public profile
• followers, publicRepos, topLanguages (array)
• signalType: stargazer | keyword | fork
• signalContext: human-readable trigger description
• repoName, repoOwner — for stargazer and fork signals
• issueTitle, issueUrl, issueBody snippet — for keyword signals
