A2P 10DLC Registration & Deliverability Setup
Get registered with the carriers and authenticated with the mailbox providers, so the messages you send are the messages people receive.
The problem we’re actually solving
This is the failure nobody sees. Messages show as sent inside GoHighLevel. There is no bounce and no error. They simply never arrive, because the brand was never registered or the sending domain was never authenticated. Businesses conclude that SMS does not work for them.
What’s included
- A2P 10DLC brand registration matching your EIN exactly
- Campaign registration written to survive first review
- SPF, DKIM and DMARC records configured and verified
- Dedicated sending domain and warm-up
- Opt-out handling, quiet hours by contact timezone
- Deliverability testing across major carriers and inbox providers
- Ongoing monitoring so a silent failure gets caught
From blueprint to live in four steps.
Audit & blueprint
We map your funnel, your sales motion and your current stack, then document exactly what gets built and why, before anyone touches your account.
Build in staging
Pipelines, funnels, workflows and integrations all get built and tested in a staging sub-account, so nothing breaks in production while you watch.
Launch & train
We cut over with zero downtime, train your team on the live system, and hand over a recorded SOP library they will actually use.
Optimise monthly
We watch deliverability, response times and conversion, then ship improvements every month against targets we agreed up front.
Where this matters most
The verticals where this does the heaviest lifting, and the number it moves in each.
A2P & Deliverability, questions we get asked
Still stuck on something specific? Ask us on a call and we will answer it properly.
Ask a questionHow long does A2P 10DLC registration take?
Brand registration is often same-day. Campaign approval usually takes one to three business days and is entirely carrier-controlled, so we submit on day one of any build rather than at the end. Rejections almost always trace to an EIN that does not exactly match IRS filing, a vague campaign description, or sample messages missing opt-out language.
Can we send SMS while registration is pending?
Technically yes, but you should not. Unregistered traffic is heavily filtered, so your test results will mislead you and you may damage the number reputation before you have properly started.
Why do our emails go to spam even though nothing bounces?
Almost always missing or misconfigured authentication. Without SPF, DKIM and DMARC aligned on a domain you actually control, mailbox providers quietly route you to spam rather than rejecting you outright, so there is no error to notice.
