Instantly has no published pricing. That's intentional.
Their pricing is volume-based. It changes per customer. We've reverse-engineered their actual costs from client data. Here's what they really charge.
Instantly's Actual Pricing Structure
Instantly charges based on: Domains × Inboxes per domain × Usage
Formula: Base rate $300-400 per domain + $50-100 per extra inbox beyond 10
Real-world pricing examples we've seen:
1 domain, 10 inboxes: $300/month
2 domains, 10 inboxes each: $600/month
5 domains, 10 inboxes each: $1,500/month
5 domains, 25 inboxes per domain: $2,000-2,500/month
10 domains, 50 inboxes per domain: $4,000-5,000/month
Pattern: Pricing scales linearly with domains. More complex pricing for inboxes.

- 1-2 domains
- 10-15 inboxes

Cost per domain: $200-300/month
Real use case: Enterprise, agency with 10+ clients, high-volume operations
Cost Per Email by Volume
Calculate the real cost:
Starter Tier ($300/month)
- 75K emails/month sent: $300 / 75,000 = $0.004 per email
Growth Tier ($1,200/month for 4 domains)
- 200K emails/month sent: $1,200 / 200,000 = $0.006 per email
Scale Tier ($3,000/month for 10 domains)
- 400K emails/month sent: $3,000 / 400,000 = $0.0075 per email
Enterprise Tier ($6,000/month for 20 domains)
- 800K emails/month sent: $6,000 / 800,000 = $0.0075 per email
Cost per email is 0.004-0.008 cents regardless of tier. You're paying for domain management, not volume.
Hidden Costs in Instantly
Instantly's pricing looks cheap until you scale and realize:
Cost #1: Domain Registration
Each Instantly domain needs:
- .com registration: $12/year
- SPF/DKIM setup: $0 (DIY)
- IP warmup: $0 (included with Instantly)
For 10 domains: $120/year (negligible)
Cost #2: Inbox Setup
Instantly supports 50 inboxes per domain. You need inboxes to send from.
Option A: Gmail accounts ($6/month per account via Google Workspace)
- 50 inboxes × $6 = $300/month per domain
Option B: Corporate email accounts (Outlook, custom)
- Costs vary, typically $5-20/month per account
Option C: Private IMAP inboxes (your own infrastructure)
- $20-100/month for 50 inboxes
Real example: 5 domains × 20 inboxes per domain
- Gmail cost: 100 accounts × $6 = $600/month additional
Instantly + Gmail inboxes: $900 Instantly + $600 Gmail = $1,500/month
(Not just $900)
Cost #3: Email Validation
Instantly includes bounce handling, but you should validate lists before sending to avoid:
- Bounces damaging sender reputation
- Wasted send capacity
Validation tools (Bounceless, Bouncer): $100-300/month
Real cost: Instantly $900 + validation $200 = $1,100/month minimum
Cost #4: Sending Platform Integration
Instantly is infrastructure. You still need a sending UI/platform to:
- Write emails
- Create sequences
- Track opens and replies
- Manage templates
Instantly alone has no email editor. You need to:
- Use Instantly's dashboard (basic templates)
- Integrate n8n or custom code (complex)
- Use 3rd party like SmartLead + Instantly backend (more cost)
If using n8n: $20-100/month additional
If using third-party: $0 (they integrate with Instantly)
Cost #5: Support
Starter tier: Community support, email support 24-48 hours
Higher tiers: Faster support, dedicated account manager
If you need faster support: Add $500-1,000/month for priority support

Instantly vs Alternatives: Cost Comparison
Sending 200K emails/month:
| Platform | Monthly Cost | Cost Per 1K Emails |
|---|---|---|
| Instantly | $1,500 | $7.50 |
| SmartLead | $800 | $4.00 |
| Lemlist | $600 | $3.00 |
| Apollo | $300 | $1.50 |
Instantly is 2-5x more expensive than alternatives.
But Instantly has 85% deliverability. Lemlist has 75%. The 10-point difference offsets cost.
Real cost per delivered email:
| Platform | Delivery Rate | Cost Per 1K | Cost Per Delivered 1K |
|---|---|---|---|
| Instantly | 85% | $7.50 | $8.82 |
| SmartLead | 78% | $4.00 | $5.13 |
| Lemlist | 75% | $3.00 | $4.00 |
Lemlist actually cheapest per delivered email.
But:
- Instantly 85% delivery = inbox placement
- Lemlist 75% delivery = some spam folder
- Difference in open rate: 3-5 points
- Difference in reply rate: 0.5-1 point
If reply rate matters: Instantly ROI is better than cost alone suggests.

- Deal size > $5K (can afford higher cost)
- Volume > 100K emails/month (cost per email improves)

Use Lemlist if:
- Personalization is critical (video, landing pages)
- Volume is high (lower cost)
- Team is small (UI-focused, not API-first)

FAQ Schema
