Marketing Agencies: Build an iMessage Upsell Service for Your GHL Clients
Summary
Agencies adding iMessage as a service to GHL clients charge $100-$300/month markup and see 94% client retention. This guide covers the exact pricing model, implementation steps, and success playbook used by top-performing agencies.
Automate iMessage to your leads—from your CRM or API
Send outbound iMessages from Salesforce, HubSpot, GoHighLevel, Clay, or any API. Higher response rates, no carrier filters.
Your clients are paying you $1,500-$5,000/month for marketing services. You're running their ads, managing their funnels, handling their CRM.
But their SMS marketing is broken.
Messages get filtered. Response rates are dropping. A2P 10DLC registration is a nightmare. And somewhere in the mix, leads are going cold.
Here's what's happening: 30-40% of SMS messages never reach prospects. Clients are losing leads they paid good money to acquire. And they're blaming the channel—or worse, your agency's work.
What if you could fix this?
240+ GHL agencies have added iMessage automation as a premium service. They're charging $100-$300/month markup. They're seeing 94% client retention. And they're doing it with less headache than SMS ever was.
The Agency Opportunity
The Problem Clients Are Facing
| Issue | Impact | Client Pain Level |
|---|---|---|
| A2P 10DLC registration | 4-6 week delay before any SMS | High |
| Carrier filtering | 30-40% of messages blocked | High |
| Rising SMS costs | $0.08-$0.15/message | Medium |
| Low response rates | 3-5% on cold outreach | Medium |
| Reputation damage | Blacklisted numbers | Critical |
Your clients are stuck. They can't launch campaigns without carrier approval. They can't scale without getting filtered. And they're paying for leads that never receive their messages.
The iMessage Solution
iMessage bypasses carrier networks entirely. No A2P registration. No carrier filtering. 94%+ delivery rates. And it works in the GHL workflows they're already using.
What this means for your agency:
- Same-day campaign launches (vs 4-6 weeks)
- Higher response rates (5-10% vs 3-5% SMS)
- Predictable costs (pay per line, not per message)
- Easy to white-label (clients never know who powers it)
iMessage automation from your stack
Connect your CRM or API. Send to iOS users without carrier limits or spam filters.

The Implementation Playbook
Phase 1: Internal Testing (Week 1)
Before selling to clients, prove it works internally.
-
Set up your own Tuco AI account
- One-click GHL OAuth
- Enable your agency account
- Test sending to 5-10 internal numbers
-
Run a controlled test
- Pick one client campaign (with permission)
- Split test: SMS vs iMessage
- Track response rates for 7-14 days
-
Document results
- Before: SMS response rate
- After: iMessage response rate
- Note: Delivery improvements, client feedback
Internal metrics to capture:
- Response rate comparison
- Client satisfaction score
- Technical issues encountered
Phase 2: Client Pitch (Week 2-3)
You're not selling a new product. You're fixing a problem.
The Pitch Framework:

-
Position as premium service:
"I can add iMessage automation to your package. It's a $100/month upgrade, and you'll see better deliverability and higher response rates."
-
Handle objections:
- "What about Android users?" → Auto-fallback to SMS included
- "How long to set up?" → Same-day, no carrier registration
- "Do I need new infrastructure?" → Works with existing GHL
Pitch materials to prepare:
- One-pager comparing SMS vs iMessage

Common Objections and How to Handle
Objection 1: "My clients have Android users"
Response:
"We automatically fall back to SMS for Android users. They get the same experience—same workflow, same message, just delivered through SMS. No extra work for you."
Objection 2: "We're already using SMS in GHL"
Response:
"SMS is working, but it's breaking down. 30-40% of your messages aren't reaching prospects. iMessage delivers 98%. Same workflows, better results."
Objection 3: "How much does this cost?"
Response:
"It depends on volume, but most clients see it pay for itself in the first month. Higher response rates mean more revenue from the same ad spend. Want me to run the numbers for your specific account?"
Objection 4: "I don't want another vendor"
Response:
"I get it. That's why this is white-labeled. Your clients see your brand. We stay invisible. And it integrates directly into the GHL workflows you're already using."
Objection 5: "What's the contract?"
Response:
"Month-to-month. No long-term commitment. Try it for 60 days—if you're not seeing better results, we can switch back."

Start with one client. Prove the results. Scale from there.
