HubSpot CRM Hygiene • Cut Marketing Contact Tiers

B2B CRM databases decay by 22.5% every year. Scrubbing your HubSpot contacts with MailVeri before your monthly billing date downgrades invalid, disposable, and abandoned contacts to free **Non-Marketing** status — while preventing HubSpot's 3% bounce suspension.

## The Hidden Cost of Unverified HubSpot Contacts

Leaving unverified, aged, or disposable contacts inside HubSpot Marketing Hub penalizes your RevOps budget twice.

### Marketing Contact Tier Bloat

HubSpot bills by your total Marketing Contact tier ($15 to $50+ per 1,000 contacts/month), whereas up to 1,000,000 **Non-Marketing Contacts** are stored for $0. Cleaning 20,000 dead contacts saves thousands per year.

### 3% Hard Bounce Lockouts

HubSpot's deliverability system flags accounts that exceed a **3% hard bounce rate** on marketing broadcasts and suspends email sending privileges if bounces cross **5%**.

### Inbound Lead Form Pollution

Competitors and bots submit burner emails (`DISPOSABLE`) on gated PDFs, webinar forms, and demo requests, triggering automated nurture bounces and skewing MQL attribution.

## Two Ways to Clean & Protect HubSpot CRM

Run a pre-billing bulk audit on existing contacts and add a real-time verification gate for new inbound leads.

### Workflow A: Pre-Billing Bulk Marketing Contact Audit

Run 48 hours before your monthly HubSpot renewal date to downgrade dead contacts before the 1st of the month

1

#### Export Active List

In HubSpot, filter contacts where Marketing contact status = Marketing contact and export as CSV (including `Record ID` and `Email`).

2

#### Verify with MailVeri

Upload the CSV to the [MailVeri Dashboard](https://app.mailveri.com/dashboard/). MailVeri appends `mailveri_status` while preserving every `Record ID`.

3

#### Set as Non-Marketing

Re-import by `Record ID` and bulk-update `INVALID`, `DISPOSABLE`, and `FULL_INBOX` contacts to **Non-Marketing Contact**.

### Workflow B: Real-Time HubSpot Workflow Verification

Works via HubSpot Custom Code actions, Webhooks, [Zapier](https://mailveri.com/integrations/zapier), [Make](https://mailveri.com/integrations/make), or [n8n](https://mailveri.com/integrations/n8n)

Validate every new contact on creation before setting them as a billable Marketing Contact or enrolling them in automated welcome sequences:

Option 1: HubSpot Operations Hub Custom Code Action (Node.js) · Outputs mailveri_status & safe_for_marketing

```javascript
// HubSpot Operations Hub — Custom Code Workflow Action (Node.js)
exports.main = async (event, callback) => {
  const email = event.inputFields['email'];

  const response = await fetch('https://api.mailveri.com/v1/verify-mail/', {
    method: 'POST',
    headers: {
      'Authorization': `Bearer ${process.env.MAILVERI_API_KEY}`,
      'Content-Type': 'application/json',
    },
    body: JSON.stringify({ email }),
  });

  const data = await response.json();

  callback({
    outputFields: {
      mailveri_status: data.status,
      is_disposable: data.is_disposable,
      is_catch_all: data.is_catch_all,
      safe_for_marketing: data.status === 'VALID',
    },
  });
};
```

Option 2: Standard Webhook Request (Zapier / Make / n8n / HubSpot Webhook) · Real-time HTTP POST

```http
POST https://api.mailveri.com/v1/verify-mail/
Authorization: Bearer YOUR_MAILVERI_API_KEY
Content-Type: application/json

{
  "email": "{{contact.email}}"
}
```

MailVeri JSON Response Payload · Map status to custom HubSpot property

```json
{
  "error": 0,
  "message": "Verified claire.bennett@vertexsaas.com successfully",
  "status": "VALID",
  "email": "claire.bennett@vertexsaas.com",
  "mail": "claire.bennett@vertexsaas.com",

## Frequently Asked Questions

Common questions about cleaning HubSpot lists and reducing Marketing Contact bills.

### Should I delete invalid contacts in HubSpot or set them as Non-Marketing?

For net-new fake or disposable form submissions, delete them immediately. For historical customers or closed-lost deals whose email addresses have decayed (`INVALID`), keep the contact record for deal attribution and set **Marketing contact status = Non-marketing contact** so you pay $0 for storage.

### When does HubSpot apply Non-Marketing Contact downgrades?

HubSpot applies Non-Marketing Contact downgrades on the next monthly assessment date (typically the 1st of the month). Running your MailVeri bulk audit 48 hours before month-end ensures your lower contact count takes effect on your very next invoice.

### Do I need Operations Hub to automate HubSpot verification?

No. If you do not have Operations Hub Professional for Custom Code actions, you can trigger real-time verification on any HubSpot plan using our [Zapier](https://mailveri.com/integrations/zapier), [Make.com](https://mailveri.com/integrations/make), or [n8n](https://mailveri.com/integrations/n8n) templates.
