Deliverability
Make sure the messages you automate actually arrive
An automation that sends perfectly and delivers to spam is worse than no automation, because you believe it is working.
Quick answer
Why do automated emails and texts fail to deliver?
Automated messages fail to deliver most often because the sending domain is not authenticated with SPF, DKIM and DMARC records, because a new sending domain or number was used at high volume without warm-up, because sender reputation has been damaged by complaints, or because required carrier registration was never completed.
The problem
What this actually fixes
Emails are being sent and landing in spam, so nobody replies and you assume the copy is wrong.
A new domain was used at volume immediately and its reputation never recovered.
SPF, DKIM and DMARC were never configured, or were configured incorrectly.
You are sending from a free email address, which most providers now reject or flag.
Bounce rates are climbing and nobody is removing invalid addresses.
SMS is failing silently on numbers that were never properly registered or warmed.
Scope
What's included
Every engagement is scoped to what you actually need. This is the full deliverable list.
Deliverable 01
Domain authentication
SPF, DKIM and DMARC records configured and verified, which is the baseline modern providers expect before trusting a sender.
Deliverable 02
Dedicated sending domain
A subdomain configured for automated sending so marketing volume does not affect your primary domain's reputation.
Deliverable 03
Warm-up plan
Volume ramped gradually on new domains and numbers rather than sending thousands on day one and burning reputation immediately.
Deliverable 04
List hygiene
Bounce handling, invalid address removal and engagement-based suppression, because sending to dead addresses damages everyone else's deliverability.
Deliverable 05
Number provisioning
SMS numbers acquired, associated with the right registration and warmed appropriately.
Deliverable 06
Monitoring
Delivery, bounce and complaint rates tracked so degradation surfaces before it becomes a crisis.
How it works
From first call to running system
- Step
Audit current state
What is configured, what is authenticated, what reputation looks like now. Often reveals problems predating the automation.
- Step
Configure records
DNS records added and verified, dedicated sending subdomain established.
- Step
Warm up
Volume increased gradually over a defined schedule rather than all at once.
- Step
Monitor and adjust
Watching delivery metrics through the ramp and correcting before problems compound.
Use cases
Where this earns its keep
Before a first campaign
Getting infrastructure right before volume rather than diagnosing failure afterwards.
Recovering damaged reputation
A domain that has been sending badly needs deliberate remediation rather than more sending.
Scaling volume
Moving from hundreds to thousands of messages needs infrastructure that hundreds did not.
The failure that hides itself
Deliverability problems are uniquely frustrating because everything reports success.
The platform sends the message. The logs show delivered. No error appears anywhere. The message sits in a spam folder nobody checks, or is silently dropped by a carrier, and the only signal is that your reply rates are worse than they should be — which is easy to blame on copy, timing, offer or audience.
Businesses spend months optimising message content when the actual problem is a missing DNS record. Checking the infrastructure first is cheap and rules out the largest confound.
Questions
Email & SMS Setup — common questions
What are SPF, DKIM and DMARC?
Three DNS records that let receiving mail servers verify your messages are genuinely from you. SPF lists authorised sending servers, DKIM cryptographically signs messages, and DMARC tells receivers what to do when the first two fail. Major providers now expect all three from bulk senders, and messages without them are treated with suspicion.
Why does warm-up matter?
Because sending reputation is built on history. A brand new domain or number sending thousands of messages on its first day looks exactly like a spammer, and providers treat it accordingly. Ramping volume gradually establishes a pattern that earns trust, and the reputation you build persists.
Should we use a separate sending domain?
Generally yes — a subdomain for automated sending. It means a deliverability problem in your marketing does not damage your ability to send ordinary business email from your main domain, which is a genuinely painful failure mode to recover from.
How do we know if we have a deliverability problem?
Falling open rates alongside stable send volume is the usual signal, as are rising bounce rates or replies stopping abruptly. The awkward part is that the failure is silent — you keep sending, the platform reports success, and the messages are simply not being seen.
Does this include A2P registration?
They are related but distinct. A2P 10DLC is the specific US carrier registration required for SMS; deliverability setup covers the broader infrastructure across email and SMS. Most US projects need both, and we usually run them together.

A2P 10DLC is the registration system US carriers require for application-to-person messaging over standard 10-digit numbers. It involves registering your brand and each messaging campaign. Without approved registration, messages to US numbers are heavily filtered or blocked outright, so it is mandatory rather than optional for US SMS.
Workflows that hold up when reality gets messy
A GoHighLevel workflow is a trigger followed by a series of conditional actions. A trigger such as a form submission or inbound call starts it, then branching logic decides what happens — sending SMS or email, waiting, assigning tasks, updating pipeline stages, booking appointments or calling external systems via webhook.
Everything GoHighLevel can run without you
GoHighLevel can automate lead capture from forms, calls, ads and chat; contact creation and pipeline movement; SMS, email and WhatsApp follow-up sequences; appointment booking, confirmation and reminders; missed-call text-back; review requests; reactivation campaigns; internal notifications; and reporting.
Connect your stack so data lives in one place
GoHighLevel integrates natively with Google and Microsoft calendars, Stripe, Meta and Google Ads, and common messaging platforms. Anything else connects through Make, n8n or Zapier, or through direct API and webhook work where no connector exists for the system involved.
Extend GoHighLevel past what the interface allows
The GoHighLevel API allows programmatic access to contacts, opportunities, calendars, conversations and workflows. It supports operations the interface does not — bulk data manipulation, custom application logic, external systems reading and writing CRM data directly, and receiving webhooks on platform events.
