GoHighLevel Texts Not Sending? A2P 10DLC Rejections, Error 30007 & 30034, Fixed in Order

If your GoHighLevel texts are not sending, the workflow is usually not the problem — the message left your automation and was stopped by registration, carrier filtering, or the contact’s own settings. The frustrating part is that GoHighLevel’s interface makes a blocked text look almost identical to a sent one. This guide shows you where the real failure appears, what the common error codes mean, and the order to fix things so you are not chasing the wrong problem.

“Sent” in the Workflow Log Is Not “Delivered”

A workflow execution log tells you the SMS action ran. It does not tell you the carrier accepted or delivered the message. Those are different events, and the gap between them is where almost all SMS problems live.

To see what actually happened, open the contact’s conversation thread and look at the individual message details and delivery status. Failed messages surface their error code there — in the conversation view, not in the workflow builder. Start every SMS investigation in the conversation thread, find the error code, then use the table below. And if the message never even left the workflow, that is a different diagnosis — work through our GoHighLevel workflow not working checklist first.

The Error Codes, Decoded

• Error 30034 — Unregistered number / A2P campaign not approved. Your number is sending application-to-person (A2P) texts without an approved 10DLC registration, or the campaign linked to the number is still pending or rejected. Fix: complete your Trust Center registration in GoHighLevel — brand first, then campaign — and wait for approval before sending marketing texts.
• Error 30007 — Message filtered by the carrier. Your number is registered, but this specific message tripped carrier spam filtering: suspicious links, spam-like wording, or a sender with a poor reputation. Fix: review the exact message content (see the hygiene section below), and check that your campaign registration actually covers this type of message.
• Error 30004 — Contact has opted out or is on DND. The contact replied STOP, was marked DND, or cannot receive messages. Fix: none needed at the platform level — respect the opt-out. Check the contact’s DND status to confirm, and never override an SMS opt-out.
• Error 30006 — Landline or invalid number. The destination cannot receive texts: a landline, a disconnected number, or a mistyped mobile. Fix: clean the number, confirm the correct mobile with the customer, and consider validating numbers on your forms so bad numbers never enter the list.

Registration errors (30034) must be fixed before filtering errors (30007) even make sense to chase — an unregistered number gets blocked regardless of how clean the message is. Work in that order.

The Four Common A2P Rejection Causes

If your campaign registration itself was rejected, it is almost always one of these four:

1. Your privacy policy doesn’t mention SMS. Carriers check that your website’s privacy policy explains how you collect phone numbers and send texts, including how to opt out. A policy with no mention of messaging is a routine rejection.
2. The campaign description is too vague. “Marketing messages for our business” tells the reviewer nothing. Describe the actual use case: appointment reminders, follow-ups to people who requested a quote, review requests — and how contacts opt in.
3. Sample messages don’t match the use case. The sample texts you submit must look like the messages the campaign describes. If the use case says “appointment reminders” but the samples are discount blasts, expect a rejection.
4. Business name doesn’t match the legal/EIN filing. The brand registration is checked against official records. If your registered legal name, EIN, or address differs from what you entered — even by punctuation or a DBA — verification can fail. Use the exact legal details from your tax filing.

Most rejections are documentation problems, not platform problems. Fix the document, resubmit, and the same campaign usually passes. All of this is part of a proper GoHighLevel setup and implementation — registration done in the wrong order is why so many accounts end up debugging it later.

Pre-Submission Checklist

Before you submit (or resubmit) an A2P campaign, confirm:

• Your website is live and publicly reachable — reviewers actually visit it.
• Your opt-in form states clearly that the person is agreeing to receive texts, with the consent language near the phone field, not buried.
• Your privacy policy includes an SMS section: what you send, message frequency, and how to opt out (reply STOP).
• Your business name, EIN, and address match your legal filings exactly.
• Your sample messages match the described use case and include your business name and opt-out language.
• The number you send from is the number attached to the campaign.

While Approval Is Pending

If your campaign is submitted and waiting, resist the urge to keep testing with live marketing texts — sending before approval is exactly what generates 30034 errors and can hurt the number’s reputation before you start. Use the waiting time productively instead: finish your workflows, write your message sequences, and test everything that doesn’t depend on carrier delivery, like internal notifications and email steps. Test texts to your own devices are fine for checking workflow logic, but judge deliverability only after approval comes through. Approval timelines vary, and resubmitting an unchanged, still-pending campaign doesn’t speed anything up.

Carrier-Filtering Hygiene

Even with registration approved, carriers filter individual messages. Keep first-contact texts clean:

• Avoid public link shorteners (bit.ly and similar) — they are one of the fastest ways to get filtered.
• Avoid links entirely in the first text where you can, and use your own domain when you do link.
• Don’t open with all-caps, heavy exclamation, or discount-blast language to someone who just opted in.
• Sequence compliance before campaigns: get registration approved, send low-volume, legitimate traffic first, and build sending reputation gradually instead of blasting a cold list on day one.

The Fix Order, Summarized

Confirm the failure in the conversation thread and note the error code. Fix registration (30034) before filtering (30007). Check the contact’s DND and the number itself before rewriting any content. Resubmit rejected campaigns with corrected documents, not identical ones. If your SMS problems keep recurring because the original setup skipped registration and deliverability entirely, that is a setup gap, not a series of bad luck — our setup and implementation work starts with exactly these foundations. Or book a call and describe what your messages are doing — we can usually tell from the error pattern where your account stands.
