Apollo + Instantly Workflow: Complete Cold Email Setup

By Puzzle Inbox Team · May 20, 2026 · 7 min read

Step-by-step workflow combining Apollo prospect data with Instantly sending platform for cold email at SMB and mid-market scale.

Apollo + Instantly: The Most Common Cold Email Stack

Apollo for prospect data and Instantly for sending platform is the most common cold email stack at SMB and mid-market scale. This workflow guide covers the integration.

Why This Stack Works

• Apollo: 275M+ B2B contacts with built-in verification ($49-99/user)
• Instantly: Sequencing, large warmup network, AI features ($30+/month)
• Together: Complete cold email operation under $200/month for solo operators

Step 1: Define ICP in Apollo

Apollo Search → Companies/People filters:

• Industry, sub-industry, company size
• Funding stage, revenue range
• Geographic location
• Tech stack used
• Job title, seniority, department
• Recent job changes (trigger event)

Step 2: Build Prospect List in Apollo

Apply ICP filters → preview matching prospects → select 500-2,000 for first campaign. Apollo verifies emails before delivering.

Step 3: Export from Apollo

Two options:

Direct Sync to Instantly

Apollo → Settings → Integrations → Instantly. Configure direct prospect sync. New matching prospects automatically push to Instantly campaigns.

CSV Export

Apollo → Export → CSV. Includes name, email, company, title, custom fields. Upload to Instantly manually.

Step 4: Verify Lists Before Adding

Apollo verifies emails as part of credit cost. Optional additional verification with Bouncer ($40/10K) or ZeroBounce for higher confidence on hard-to-find prospects.

Step 5: Set Up Cold Email Inboxes in Instantly

Connect 5-30 cold email inboxes via OAuth. Pre-warmed inboxes from Puzzle Inbox ready in 24-72 hours.

Step 6: Create Campaign in Instantly

New Campaign → Upload prospect list → Add sequence steps. Best practice 4-email sequence:

• Email 1: Specific relevance hook + value prop
• Email 2 (3 days): Case study or proof
• Email 3 (5 days): Different value angle
• Email 4 (7 days): Breakup with easy out

Step 7: Apply Personalization Variables

Use Apollo data fields in Instantly merge tags:

• {{firstName}} — prospect first name
• {{companyName}} — Apollo-provided company
• {{jobTitle}} — Apollo-provided title
• {{customField1}} — recent funding, hiring, etc.

Step 8: Launch Campaign

Schedule sends Tuesday/Thursday morning. Instantly rotates across connected inboxes.

Step 9: Manage Replies in Unibox

Instantly Unibox aggregates replies across all inboxes. AI auto-classifies. Route positive replies to sales/founder for response within 1 hour.

Step 10: Track Performance

Instantly Analytics:

• Reply rate per campaign
• Bounce rate (target under 2%)
• Open rate (less reliable post Apple MPP)
• Booking conversion

Apollo also tracks campaign performance from data side.

Apollo Free vs Paid for Cold Email

Apollo Free:

• Limited credits (around 50/month)
• Workable for testing only
• Not enough for sustained cold email operations

Apollo Basic ($49/user):

• 2,400 credits/month
• Realistic for solo SDR
• Includes basic sequencing if not using Instantly

Apollo Professional ($99/user):

• 12,000 credits/month
• Realistic for SDR running multiple campaigns
• Most common Apollo tier for cold email

The Optimal Apollo + Instantly Stack

• Apollo Professional: $99/user/month (data)
• Instantly Hypergrowth: $77.60/month (sending)
• Puzzle Inbox 10-30 inboxes: $20-135/month (infrastructure)
• Total: $200-310/month for complete cold email operation

Common Workflow Mistakes

• ICP too broad in Apollo (low reply rates downstream)
• Skipping Apollo verification (expecting separate verification but Apollo already does it)
• Not using merge tags for personalization (generic emails get 1% reply rate)
• Manual CSV export every campaign (set up direct sync)
• Hard CTAs in Instantly sequence (3x lower reply rates)
