Why GitLeads + GMass for Developer Outreach
GMass turns Gmail into a powerful cold email platform — mail merge, automatic follow-ups, open/click tracking, and reply detection. When you connect it to GitLeads, every GitHub developer showing buying intent triggers an automatic campaign sequence. GitLeads finds the signal. GMass handles the outreach. You close the deal.
Integration Architecture
GitLeads does not have a native GMass integration. The recommended approach is to route signals through Google Sheets, which GMass polls automatically, or use a webhook-to-Sheets bridge:
- GitLeads webhook fires when a new GitHub signal is captured
- A lightweight middleware (n8n, Make, Zapier, or Apps Script) appends the lead to a Google Sheet
- GMass polls that Sheet on your configured schedule and triggers your campaign
- GMass sends personalized emails using the lead data as merge fields
- GMass tracks opens, clicks, and replies — auto-sends follow-ups to non-openers
Step 1 — Configure Your GitLeads Webhook
In your GitLeads dashboard, go to Integrations → Webhooks and add a new endpoint. GitLeads will POST enriched lead data whenever a signal fires:
// GitLeads webhook payload
{
"event": "lead.captured",
"lead": {
"githubUsername": "devuser123",
"name": "Priya Sharma",
"email": "priya@startupxyz.dev",
"company": "StartupXYZ",
"bio": "Backend engineer — Go, Postgres, Kubernetes",
"location": "Bangalore, IN",
"followers": 287,
"topLanguages": ["Go", "TypeScript", "Python"],
"signalType": "stargazer",
"signalContext": "Starred kubernetes/kubernetes",
"capturedAt": "2026-05-12T11:00:00Z"
}
}Step 2 — Bridge to Google Sheets via Apps Script
Create a Google Sheet with columns: Email, FirstName, Company, GitHubUsername, SignalContext. Deploy this Apps Script as a web app to receive webhook POSTs from GitLeads:
// Google Apps Script — paste in Tools > Script editor
function doPost(e) {
const payload = JSON.parse(e.postData.contents);
const sheet = SpreadsheetApp.getActiveSpreadsheet()
.getSheetByName('GitLeads');
sheet.appendRow([
payload.lead.email,
(payload.lead.name || '').split(' ')[0],
payload.lead.company || '',
payload.lead.githubUsername,
payload.lead.signalContext,
new Date(payload.lead.capturedAt).toLocaleDateString(),
]);
return ContentService.createTextOutput('OK');
}Step 3 — Connect GMass to Your Sheet
In Gmail, compose a draft and click the GMass button. Connect it to your Google Sheet. GMass will treat each row as a recipient and merge column values into your email template.
- Select your GitLeads Google Sheet as the data source
- Map columns: {Email} = email column, {FirstName} = name column, {Company} = company column
- Write subject using merge tags: "Re: your {SignalContext} work"
- Set up follow-up sequence: 2 days, 4 days, 7 days for non-openers
- Enable reply detection — GMass stops the sequence when a prospect replies
Best Practices for GitHub Lead Email Sequences
- Reference the specific GitHub signal in the opening line — it shows relevant context
- Keep sequences to 3–4 emails maximum for developer audiences — they value brevity
- Send from a personal Gmail, not a marketing alias, for better deliverability
- Time your first email to 1–2 hours after GitLeads captures the signal for maximum relevance
- Use GMass's "New Leads Only" Sheet polling to avoid emailing the same person twice
