## The HighLevel Bounce Suspension Problem

LeadConnector Email enforces an automated Acceptable Use Policy (AUP) monitoring cluster-wide bounce rates. When onboarding legacy client lists, agencies face immediate account freezes.

### The 2% Hard Ceiling

GHL mandates bounce rates below 2%. If an onboarding campaign spikes past 3%–5%, the system triggers an immediate automated block on outbound email.

### The 3-Strike Policy

Violations escalate fast: Strike 1 blocks sending for 12 hours. Strike 2 blocks for 24 hours. Strike 3 is a permanent sub-account sending revocation.

### The Native Markup

GHL charges $2.50 per 1,000 checks ($250 per 100K). On custom Mailgun, it costs up to $0.012 per email (about $685 per 100K). High volume list cleaning becomes prohibitive.

## Stop overpaying for GHL List Sanitization

Compare MailVeri's agency-first pricing against HighLevel's native tools and legacy providers:

| Provider | Cost per 100K | Credit Expiration | Net Agency Savings |
| --- | --- | --- | --- |
| MailVeri API & Bulk | $59 | Never ExpiresPay-As-You-Go | BaselineBest Value |
| HighLevel LC Email Validation | $250$2.50/1k | Tied to Sub-Account Wallet | Save 76% with MailVeri |
| Mailgun (Connected to GHL) | ~$685~$6.85/1k | Monthly Billing Plan | Save 91% with MailVeri |
| NeverBounce | $400$4.00/1k | 12-Month Expiration | Save 85% with MailVeri |

## How to connect MailVeri with GoHighLevel

Because GoHighLevel does not host 3rd-party verification apps on its App Marketplace, agencies utilize two complementary, native integration paths:

Method 1: Bulk Pre-Import

### Pre-Import CSV Cleaning

The mandatory firewall when onboarding new agency clients: clean their legacy CRM database before importing into GHL to eliminate historical list rot.

- Clean up to 1,000,000 contacts per batch
- 76% cheaper than native LC Email ($59 vs $250 / 100K)
- Catch-All & Full-Inbox detection included free

Method 2: Real-Time Webhook

### GHL Workflow Custom Webhook

Validate incoming opt-ins from landing pages, surveys, and lead funnels via HighLevel Workflows before automated nurture emails fire.

- Native GHL Custom Webhook action (no Zapier needed)
- Real-time verification with If/Else DND branching
- Supports JSON and URL-encoded payloads seamlessly

### Method 1 Walkthrough: Pre-Import Bulk List Sanitization

Best for: New client onboarding, cold outreach lists, and aged CRM database migrations.

Step 1: Export CSV

Export the client's customer contacts from their old CRM, POS, or database as a standard CSV or Excel file.

Step 2: Upload to MailVeri

Upload directly to MailVeri Bulk Cleaning. Our async workers test MX records, disposable filters, and live SMTP handshakes.

Step 3: Download Clean

Download only `VALID` contacts. Inconclusive records are 100% auto-refunded.

Step 4: Import to GHL

In HighLevel Sub-Account → Contacts → Import Contacts. Safe list keeps bounce rates strictly under 1.5%.

### Method 2 Walkthrough: Real-Time Lead Validation in GHL Workflows

Best for: Form submissions, calendar bookings, survey funnels, and webhook lead captures.

A

**Set Workflow Trigger:** Choose *Form Submitted*, *Survey Submitted*, or *Contact Created* in your GHL Sub-Account Workflow Builder.

B

**Add Action — Custom Webhook:** Set Method to `POST`, URL to `https://api.mailveri.com/v1/verify-mail/`, and include your API key header. Toggle ON **“Save response for this Webhook”** and click *Test Webhook* so HighLevel captures the return schema.

C

**Add Action — If/Else Branch:**

- Branch 1 (Valid Email): If `{{webhook.status}}` equals `VALID` → Apply Tag `email-verified` → Proceed to email nurture sequence.
- Branch 2 (Invalid / Risky Email): If `{{webhook.status}}` does not equal `VALID` → Apply Tag `email-invalid` → Action: **Update Contact Field → DND (Do Not Disturb) — Email: Enabled** → Send SMS or WhatsApp fallback.
