The problem I solve

You already paid for the lead. Most of the loss happens after it arrives.

01

Texts get blocked or rejected

No A2P 10DLC approval, or a campaign stuck in rejection, means your follow up texts never arrive.

02

The first reply takes hours

By then the lead has contacted two competitors and is talking to whoever answered first.

03

Missed calls die in voicemail

Your team is busy, the call goes unanswered, and nobody calls or texts back.

04

One follow up, then silence

Leads that were not ready today go cold, even though many of them buy in the next few months.

What I fix

Everything between the first click and the booked appointment.

Real sample

SMS Terms page is complete: STOP, HELP, message frequency and data rates are all covered.

Worth reviewing: the form the ads point to requires a phone number but shows no SMS disclosure where it is collected.

Worth reviewing: three different business numbers across the site, and one is not listed in the SMS Terms.

Fix first

Add the consent block to the ad form, then confirm every texting number is on the registered campaign and routes to the same team.

Questions

A2P 10DLC and SMS questions, answered

What is A2P 10DLC registration?

A2P 10DLC is the system US carriers use for business texts sent from normal 10 digit phone numbers. You register your business (the brand) and what you text about (the campaign) with The Campaign Registry through your provider, such as Twilio, GoHighLevel or RingCentral. Unregistered business texts get filtered or blocked.

Why was my A2P 10DLC campaign rejected?

The usual reasons are a website missing a Privacy Policy or SMS Terms, no clear SMS consent where the phone number is collected, sample messages that don't match the use case, or business details that don't match your EIN records. I find the exact cause and fix it before resubmitting. See how rejection fixes work.

Can you set up Twilio SMS for my business?

Yes. I set up Twilio numbers, messaging services, A2P registration, webhooks and the automations that send and reply to texts, then test everything end to end. More on Twilio and GoHighLevel SMS.

Do you work in GoHighLevel and LeadConnector?

Yes. I register A2P inside GoHighLevel (LeadConnector), build the workflows, missed call text back and follow up, and fix delivery problems, including for agencies with many sub accounts.

Which SMS gateway should I use: Twilio, Telnyx or LeadConnector?

If you run on GoHighLevel, LeadConnector is usually simplest. If you need custom integrations or your own app, Twilio or Telnyx give you more control. I'll recommend one based on your tools and volume.

Do I need toll free verification or 10DLC?

Both work for business texting. 10DLC suits local numbers and most small businesses, while toll free numbers need their own verification. If a toll free request keeps getting rejected, moving to 10DLC is often the faster path.
