Clean GoHighLevel contacts before every campaign

Why agencies clean GHL contacts before campaigns

GoHighLevel (GHL) is built for agencies running marketing for many clients at once. Each client lives in a sub-account with its own contacts, funnels, workflows, and sending setup. Contacts pour in from lead ads, landing-page forms, imported spreadsheets, and manual entry — and the messy, high-volume nature of lead capture means typos, fake signups, and dead addresses are common. When a workflow fires an email or SMS to that list, the bad addresses bounce and the fake ones inflate complaint rates.

The reputational cost lands on the client's sending domain, and by extension on your agency. A sub-account that keeps bouncing gets throttled by mailbox providers, its automations stop landing in the inbox, and the client blames you for poor campaign results. Because you manage many sub-accounts, a single sloppy import can quietly damage several clients before anyone notices.

Verifly gives you one API to clean every sub-account's contacts before a campaign runs. Each address gets a live mailbox check returning deliverable, undeliverable, or risky, plus disposable, role, and catch-all flags. You strip the junk before the workflow sends, and every client's deliverability stays defensible.

Clean a sub-account list before launch

1. Export the contacts for the sub-account you're about to campaign to, or pull them via the GHL contacts API.
2. Get a free Verifly key at verifly.email/api/v1/autonomous/register — 100 credits, no card, no captcha.
3. POST the email column to /verify/batch. Verify each sub-account's list separately so results map cleanly back.
4. Remove undeliverable and disposable rows. For SMS-heavy accounts, this also strips fake signups that never had a real inbox.
5. Push only clean contacts into the workflow or campaign and trigger the send.

const emails = subAccountContacts.map(c => c.email)

const res = await fetch('https://verifly.email/api/v1/verify/batch', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer vf_your_api_key',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({ emails }),
})

const { results } = await res.json()
const clean = results.filter(r => r.result === 'deliverable')
console.log(`${clean.length} contacts safe to campaign in this sub-account`)
