For marketing and GoHighLevel agencies

SMS, WhatsApp and iMessage for marketing agencies

Run texting for every client from one login. Each client gets its own sub-account and numbers, your GoHighLevel workflows send through real SIMs, WhatsApp and iPhones, and replies land back in GHL Conversations. SMS goes out from your own SIMs, so there is no A2P campaign to file for each new client.

  • Unlimited sub-accounts
  • Native GoHighLevel integration
  • No per-message fees
Who it is for

Built for agencies that text on behalf of clients

If you manage lead follow-up, booking and reviews for several local businesses, these are the problems VoidFix takes off your plate.

GoHighLevel agencies

You run client sub-accounts in GHL and want workflows to text from a real number without waiting 2 to 3 weeks for each client's A2P approval.

Lead-generation agencies

You sell leads or appointments, so the first reply has to go out the moment a form is filled, and the cost per text eats into your margin.

Agencies watching messaging costs

Per-segment billing grows with every campaign. A flat monthly fee per plan makes client pricing easier to quote.

Workflows

Agency workflows you can run for each client

Build these once in GoHighLevel (or Zapier, Make or the API), then copy them into every client sub-account.

Speed-to-lead

New form or ad lead instant text

The moment a lead comes in, a workflow texts them from the client's number so the conversation starts while they are still interested.

SMSWhatsAppiMessage

Missed-call text-back

Missed call text the caller

When a client misses a call, a missed-call trigger in the CRM workflow sends a text so the caller isn't lost to a competitor.

SMS

Appointment reminders

Booking made scheduled reminder

Confirm the booking straight away and schedule a reminder before the appointment. Customers can reply to confirm or reschedule.

Review requests

Job marked done review link

Send a short thank-you with the client's review link once the job or visit is complete.

SMSiMessage

Old-lead reactivation

Tag or list Spintax campaign

Re-engage cold leads who opted in earlier. Spintax varies the wording and Number Warmup protects new SIMs.

SMSWhatsApp

Click-to-WhatsApp ad leads

Meta ad lead AI chatbot qualifies

Track leads from Facebook and Instagram click-to-WhatsApp ads, tag them, and let the AI chatbot answer first questions before a human takes over.

WhatsApp
Templates

Message templates agencies use

Copy these into your workflows. Words in curly brackets are Spintax choices; {{name}}-style fields are your CRM's custom values.

Speed-to-lead

{Hi|Hey} {{first_name}}, thanks for your enquiry with {{business_name}}. Is now a good time for a quick call, or would you prefer a time later today?

Missed-call text-back

Hi, this is {{business_name}}. Sorry we missed your call. How can we help? Reply here and we'll get back to you shortly.

Review request

Thanks for choosing {{business_name}}, {{first_name}}. If you have a minute, a quick review would help us a lot: {{review_link}}

Old-lead reactivation

{Hi|Hello} {{first_name}}, you asked about {{service}} a while back. We have openings this month. Want me to send a few times? Reply STOP to opt out.

Marketing and reactivation texts need the person's prior consent and a working opt-out.

Keep the opt-out line on marketing texts and honour every STOP. What still applies without A2P registration

Channels

Which channel fits each client

All three run from one VoidFix account and plug into GoHighLevel. Most agencies start with SMS and add the others client by client.

SMS: the default

Reaches any mobile phone. Unlimited texts on paid plans from Android phones and SIMs, from $49/mo for 5 devices. SMS plans

WhatsApp: international clients

Uses the client's own WhatsApp or WhatsApp Business number, linked by QR code. Good for click-to-WhatsApp ads and markets where WhatsApp is the norm. From $19/mo. WhatsApp plans

iMessage: high-value leads

Blue-bubble messages from real iPhones for clients whose leads are mostly iPhone users. Each line reaches 50 unique contacts a day, from $99/mo per line. iMessage plans

FAQ

Agency FAQ

Can each client have its own numbers?

Yes. Every plan includes unlimited sub-accounts and unlimited SIMs per sub-account, and you can assign numbers to specific users or clients. With the Number Pool, several SIMs can share one GoHighLevel sub-account.

Do I need to register A2P 10DLC for every client?

Not for SMS sent through VoidFix, because texts go out from SIMs in your Android phones rather than registered 10DLC numbers. Carrier rules still apply: text people who opted in, include an opt-out, and use Warmup and Spintax. How SMS without A2P registration works.

Which plan suits an agency?

Most agencies pick the Starter SMS plan at $99/mo, which connects up to 20 devices so each client can have its own numbers. Extra SIMs are $10 each. For WhatsApp, Growth ($79/mo) covers 5 accounts and Business ($149/mo) covers 10.

Can I refer clients and earn from it?

Yes. The affiliate program pays 20% recurring commission on every payment from customers you refer, for as long as they stay active. Affiliate program details.
