SmartLead is the #2 cold email platform (after Instantly). 100,000+ businesses use it for B2B outreach.
This guide covers: account creation, inbox connection, Supersearch list building, warmup configuration, and first campaign launch.
Part 1: Account Creation & Inbox Connection
Step 1: Create SmartLead Account
- Visit smartlead.ai
- Sign up (email, password, company name)
- Verify email
- Complete profile
- Choose plan (Starter $49/mo, Pro $99/mo, Enterprise custom)
Step 2: Connect Email Inbox
SmartLead requires SMTP access to your email account.
For Gmail:
- Dashboard → Inboxes → Add Inbox
- Select Gmail
- Log in with Google account
- Grant permissions (SmartLead needs read/send access)
- Verify connection
- Test send (SmartLead sends test to itself)
For Outlook:
- Dashboard → Inboxes → Add Inbox
- Select Outlook
- Log in with Microsoft account
- Grant permissions
- Verify connection
Best Practice: Use company domain Gmail or Outlook (not personal email).
Step 3: Add Custom Sending Domain (Optional but Recommended)
Using custom domain improves deliverability:
- Inboxes → Add Custom Domain
- Enter domain (e.g., campaign.company.com)
- SmartLead provides DKIM/SPF/DMARC records
- Add records to domain registrar
- Wait 24-48 hours for DNS propagation
- Verify in SmartLead
Same as Instantly: DKIM/SPF/DMARC critical for inbox placement.
Part 2: Supersearch (SmartLead's List Building Tool)
SmartLead's Supersearch finds decision-makers automatically.
How Supersearch Works
- Dashboard → Supersearch
- Enter criteria:
- Industry (e.g., SaaS)
- Company size (10-500 employees)
- Decision-maker title (e.g., VP Growth)
- Location (UK, Germany, etc.)
- SmartLead scrapes web + databases
- Returns 5,000-50,000 contacts per search
- Download as CSV or export to campaign
Supersearch Example: UK SaaS VPs
- Supersearch → Create Search
- Criteria:
- Industry: Software / SaaS
- Company Size: 10-500 employees
- Title: VP Growth OR Head of Sales
- Country: UK
- Verification: Verified emails only
- Click "Search"
- Results: 8,500 contacts (typically)
- Export to campaign
Supersearch Filters (Advanced)
- Technologies Used: Find companies using specific tech (HubSpot, Salesforce, etc.)
- Recent Funding: Companies that raised funding recently (more likely to buy)
- Employee Growth: Companies hiring (expansion = budget)
- Revenue Range: Filter by estimated revenue (enterprise vs. SMB)
Part 3: Warmup Configuration
SmartLead calls it "Inbox Warm-Up." Same concept as Instantly.
Enable Warmup
- Settings → Warmup
- Enable "Inbox Warm-Up"
- Set schedule:
- Week 1: 25-50 emails/day
- Week 2: 50-100 emails/day
- Week 3: 100-150 emails/day
- Save
How It Works
SmartLead sends to warmup addresses (other inboxes) that open + click. ISPs see: legitimate engagement → increase sender reputation.
Duration: Minimum 2-3 weeks. Don't skip.
Part 4: Campaign Creation
Step 1: Create Campaign
- Dashboard → Campaigns → New Campaign
- Name (e.g., "UK SaaS Q1 2026")
- Select inbox/domain
- Upload CSV or select Supersearch results
- Map columns: First Name, Last Name, Email
- Continue
Step 2: Write Email Sequence
SmartLead supports 5+ emails per sequence (more than Instantly).
Recommended 4-Email Sequence:
Email 1 (Day 1):
`
Subject: [Company]: 34% faster customer onboarding?
Body: Hi [First Name], I noticed [Company] growing in [Market]. We helped [similar company] reduce onboarding time by 34%. Open to a quick chat?
`
Email 2 (Day 4):
`
Subject: Case study from [similar company]
Body: Following up on my previous message. Here's a real case study showing the results.
`
Email 3 (Day 8):
`
Subject: Final thought
Body: One more reason this might make sense for your team. [Brief value prop]
`
Email 4 (Day 15):
`
Subject: Closing conversation
Body: Looks like this isn't the right time. No hard feelings. Reach out if situation changes.
`
Step 3: Configure Sending Schedule
- Campaign Settings → Sending
- Daily limit: 50-100 emails (start conservative)
- Sending hours: 9 AM - 5 PM
- Days: Monday - Friday
- Timezone: Recipient's timezone (if available)
- Save
Pro Feature (SmartLead): Timezone auto-detection. Sends 10 AM in recipient's timezone automatically.
Step 4: Set Reply Tracking
- Campaign Settings → Replies
- Enable "Auto-Forward Replies"
- Set email address (where replies go)
- Save
Benefit: Replies automatically forwarded to your inbox (don't miss responses).
Part 5: Monitoring & Optimization
Dashboard Metrics
- Sent: Total emails dispatched
- Open Rate: Percentage who opened (target 15-25%)
- Click Rate: Percentage who clicked (target 8-15%)
- Reply Rate: Percentage who responded (target 3-8%)
- Bounce Rate: Keep <5%
- Spam Rate: Keep <0.5%
Real-Time Optimization
If Open Rate Low (<10%):
- Subject lines weak (try A/B testing)
- Warmup not complete (wait longer)
- Check spam folder (domain reputation issue)
If Click Rate Low (<5%):
- Email body unclear
- CTA weak (not specific)
- Cut email to <75 words
If Reply Rate Low (<2%):
- Target wrong (not right decision-maker)
- Personalization weak
- Offer unclear
If Bounce Rate High (>5%):
- List quality bad
- Verify emails before sending (use Superse arch's "Verified Only" filter)
Part 6: Advanced Features (Unique to SmartLead)
AI Email Generation
SmartLead's AI writes emails automatically:
- Campaign Settings → AI Email Writer
- Input: Prospect info, company, pain point
- SmartLead generates subject + body
- Edit as needed
- Use in campaign
Note: AI emails are decent starting point, but manual personalization outperforms 2-3x.
Multi-Inbox Rotation
Send from multiple inboxes simultaneously:
- Add 3-5 inboxes
- Create single campaign
- SmartLead distributes sends across inboxes
- Effect: Looks like different teams sending (better reputation)
Local Number Integration
SmartLead can add local phone numbers to email footer:
- Settings → Phone Numbers
- Add phone numbers per country
- Emails show local number (builds trust in that market)
Part 7: Comparing Instantly vs SmartLead
| Feature | Instantly | SmartLead |
|---|---|---|
| Setup Complexity | Easy | Easy |
| Email Deliverability | Excellent | Excellent |
| Warmup Configuration | Native | Native |
| A/B Testing | Yes | Yes |
| List Building | No (use Apollo) | Yes (Supersearch) |
| AI Email Writing | No | Yes |
| Multi-Inbox Rotation | Yes | Yes |
| Timezone Intelligence | Basic | Advanced |
| Price | $49-199/mo | $49-199/mo |

Bottom Line: Instantly better for deliverability + scale. SmartLead better for all-in-one (includes list building).
Part 8: Troubleshooting
Problem: Emails not sending
- Check inbox connection (verify status)
- Verify warmup not limiting volume
- Check daily limit setting
Problem: Low open rate
- Wait for warmup to complete
- A/B test subject lines
- Check domain reputation (DKIM/SPF/DMARC)
Problem: High bounce rate
- Use Supersearch's "Verified Only" filter
- Verify list with Hunter.io before upload
- Check email quality
Problem: Flagged as spam
- Slow warmup (reduce to 25/day)
- Improve subject lines (less clickbaity)
- Wait 2-3 weeks before scaling again
