Instantly Setup Guide: Configure Campaigns for Maximum Deliverability

Instantly is the #1 email platform for cold email. But most users configure it wrong, destroying deliverability before campaigns start.

This guide walks through proper setup: account connection, warmup, pool rotation, sending schedules, and compliance for European markets.

Part 1: Initial Account Setup

Step 1: Create Instantly Account

1. Go to Instantly.ai
2. Create account (email + password)
3. Verify email
4. Complete profile (company name, role)
5. Choose plan (Starter €49/mo for testing, Pro €99/mo for scaling)

Step 2: Connect Email Account

1. Dashboard → Integrations → Email Account
2. Select provider (Gmail, Outlook, etc.)
3. Grant permissions (Instantly needs SMTP access)
4. Confirm connection
5. Test send (Instantly sends test email to itself)

Step 3: Add Sending Domain(s)

Critical: Use custom domain (not Gmail/Outlook account). This protects your primary email and improves deliverability.

1. Domains → Add New Domain
2. Enter domain (e.g., campaign.company.com)
3. Instantly provides DKIM/SPF/DMARC records
4. Add records to your domain registrar (Namecheap, GoDaddy, etc.)
5. Wait 24-48 hours for DNS propagation
6. Verify domain in Instantly

DKIM/SPF/DMARC Setup (Critical for Deliverability):

• DKIM (DomainKeys Identified Mail): Digitally signs emails (proves authenticity)
• SPF (Sender Policy Framework): Authorizes IPs to send from domain
• DMARC (Domain-based Message Authentication): Policy on how to handle failures

Your domain registrar should have fields for these. Instantly provides exact values to paste.

Step 4: Configure Sending IP Pool

Instantly manages IPs, but you can configure rotation:

1. Settings → IP Rotation
2. Select "Auto Rotate" (recommended)
3. Set rotation frequency (every 50 emails, every 100 emails)
4. Save

Why rotate? ISPs track sending patterns. Rotation makes it look like emails come from different sources (more authentic).

Part 2: Warmup Configuration (Critical for Deliverability)

Warmup Purpose: Build sender reputation BEFORE aggressive sending.

Think of it like this: New domains have zero reputation. ISPs are suspicious. Warmup proves you're legitimate.

Warmup Schedule (Recommended)

Week 1: 25-50 emails/day to engaged contacts

Week 2: 50-100 emails/day to warm leads

Week 3: 100-150 emails/day to broader list

Week 4+: 150-300 emails/day (domain now warm)

How to Configure Warmup in Instantly

1. Campaigns → Warmup Settings
2. Enable "Warmup Mode"
3. Set daily warmup limit (start at 50)
4. Select "Warmup Engagement" (Instantly sends to warmup addresses that open + click)
5. Save

Warmup Works Because:

• Open rate = positive signal (ISP sees: recipient engaged)
• Click rate = positive signal (ISP sees: not spam)
• Buildup = gradual reputation increase

Manual Warmup (If Warmup Mode Not Enough)

1. Create CSV of 100-200 emails you own or control:

• Your team members
• Partners who agreed
• Client emails (who know cold email is coming)

1. Send 1 email per person during warmup period
2. Ask them to open + click
3. Track opens/clicks
4. After 2 weeks, domain reputation high enough for cold email

Part 3: Campaign Configuration

Step 1: Create Campaign

1. Campaigns → New Campaign
2. Name (e.g., "UK SaaS Q1 2026")
3. Select sending domain
4. Upload CSV (First Name, Last Name, Email, Custom Variable 1, etc.)
5. Map columns in Instantly
6. Continue

Step 2: Write Email Sequence (4 Emails Recommended)

Email 1 (Day 1):

`

Subject: [Company]: [Metric]?

Body: Hi [First Name], I noticed [Company] growing in [Market]. We helped [similar company] achieve [result]. Open to 15 minutes next week?

`

Email 2 (Day 4):

`

Subject: Quick question...

Body: Still thinking about our previous message? Here's a case study that might help.

`

Email 3 (Day 8):

`

Subject: Final thought

Body: Last chance to chat about [specific value]. Let me know if you're interested.

`

Email 4 (Day 15+) - If Still No Response:

`

Subject: Closing out...

Body: Taking you off list. No hard feelings. Cheers!

`

Step 3: Configure Sending Schedule

1. Campaign Settings → Sending Schedule
2. Daily limit: 50-100 emails (start conservative)
3. Sending hours: 9 AM - 5 PM (business hours for recipient timezone)
4. Days: Monday - Friday (most people check work email M-F)
5. Save

Why these hours? Cold emails sent during business hours get higher open rates (people actually checking email).

Step 4: Set Reply Tracking

1. Campaign Settings → Reply Handling
2. Enable "Auto-Forward Replies" to your email
3. Set reply threshold (automatically move to "responded" bucket after 1 reply)
4. Save

This ensures: You don't miss responses buried in Instantly interface.

Part 4: Advanced Configuration

Setting Up A/B Testing

1. Create Campaign
2. Add 2 subject lines (for A/B test)
3. Segment list: 50% get Subject A, 50% get Subject B
4. Send simultaneously
5. Track opens/clicks by subject
6. After 500 emails, identify winner
7. Use winner for remaining list

Pool Rotation Strategy

1. Create 3-5 campaigns (same list, different domains)
2. Set each to send at different hours
3. Rotate between domains
4. Net effect: Looks like different teams sending (improves deliverability)

Example:

• Campaign 1 (campaign.com): 50 emails 9 AM
• Campaign 2 (outreach.com): 50 emails 11 AM
• Campaign 3 (connect.com): 50 emails 2 PM
• Campaign 4 (reach.com): 50 emails 4 PM

Smart Send (For International Campaigns)

1. Campaign Settings → Smart Send
2. Enable "Recipient Timezone"
3. Select sending hour (e.g., 10 AM)
4. Instantly sends 10 AM in RECIPIENT'S timezone, not yours
5. Save

Benefit: Email arrives during recipient's business hours regardless of their timezone.

Part 5: Compliance Configuration (European Markets)

GDPR Compliance

1. Campaign Settings → Compliance
2. Enable "GDPR Compliant Mode"
3. Requires:

• Clear unsubscribe link (mandatory)
• Sender address visible
• Clear sender identification

1. Save

Unsubscribe Link Setup

1. Campaign Settings → Unsubscribe
2. Enable "Unsubscribe Link"
3. Make sure link appears in email footer
4. Test unsubscribe flow (click link, verify removal)
5. Maintain suppression list (never email unsubscribed contacts again)

Part 6: Monitoring & Optimization

Dashboard Metrics to Track

• Open Rate: Target 15-25% (problem if <10%)
• Click Rate: Target 8-15% (problem if <5%)
• Response Rate: Target 3-8% (problem if <2%)
• Bounce Rate: Keep <5% (problem if >10%)
• Complaint Rate: Keep <0.1% (ISP will blacklist you if >1%)

Optimization Actions

If Open Rate Low (<10%):

• Subject lines weak (too generic)
• Sending time wrong (not business hours)
• Domain reputation low (need more warmup)
• Action: A/B test subject lines, check domain warmup status

If Click Rate Low (<5%):

• Email body weak (no curiosity/urgency)
• CTA unclear (not asking specific question)
• Email too long (cut to 75-100 words)
• Action: Simplify message, clearer CTA

If Response Rate Low (<2%):

• Target list wrong (not right decision-maker)
• Personalization weak (too generic)
• Offer unclear (what are you actually selling?)
• Action: Re-segment list, re-personalize, clarify value prop

If Bounce Rate High (>5%):

• List quality bad (invalid emails)
• Domain reputation damage (too aggressive sending)
• Action: Use Hunter.io to verify emails, slow domain warmup

If Complaint Rate High (>0.1%):

• Email perceived as spam
• Sending to wrong audience
• Subject line deceptive
• Action: Improve subject lines, target right audience, slow warmup

Part 7: Scaling

When to Scale Sending Volume

Safe to 2x volume if:

• Bounce rate stable <5%
• Complaint rate stable <0.1%
• Open rate stable 15%+
• Domain not flagged by ISP

Process:

1. Increase daily limit from 50 to 100
2. Monitor metrics for 3-5 days
3. If stable, increase to 150
4. Repeat until reaching 300-400 daily (max sustainable)

When to Add New Domain

After first domain sends 10,000+ emails and proves stability:

1. Register 2nd domain
2. Warm for 2-3 weeks
3. Send same campaign from 2nd domain
4. Repeat with 3rd domain

Why multiple domains? Spreads reputation across domains, prevents single ISP blacklist from destroying campaigns.

Part 8: Troubleshooting

Problem: Low Open Rates

• Check domain warmup (is it complete?)
• Verify DKIM/SPF/DMARC setup
• Check ISP blacklists (mxtoolbox.com)
• A/B test subject lines

Problem: High Bounce Rate

• Verify email list quality (use Hunter.io)
• Check domain reputation (might be flagged)
• Slow warmup (domain reputation recovering)

Problem: Complaints/Spam Folder

• Subject line too clickbaity?
• Sending to disengaged list?
• Too many emails too fast?
• Reduce volume, slow warmup

Problem: Campaign Not Sending

• Domain not verified (check Status)
• Daily limit reached (increase limit)
• Recipient email invalid (check bounce rate)
• DKIM/SPF/DMARC misconfigured (verify in domain registrar)
