Managing client communications across email, phone, and SMS can quickly become overwhelming—especially if you're juggling multiple platforms. Most agencies waste hours switching between tools, losing messages in the shuffle, and missing follow-up opportunities. GoHighLevel solves this by consolidating all your outreach channels into one unified inbox. In this guide, I'll walk you through the exact steps to configure authenticated email, phone calls, and SMS campaigns so you can manage your entire client communication strategy from a single dashboard.

Getting Started: Complete Account Setup for Communications
Before you dive into email, phone, and SMS setup, your GoHighLevel account needs foundational configuration. First, log in to your account and navigate to Settings in the main menu. Here you'll find all the core modules you need to configure: business details, domain authentication, phone numbers, and email services.
Start by completing your business profile. Go to Settings → Business Information and fill in your agency name, address, phone number, and website. This information appears in email signatures and caller ID, so accuracy matters for professional credibility. Next, verify your domain in Settings → Domains. This step is critical because it enables email authentication (SPF, DKIM, DMARC records), which prevents your emails from landing in spam folders.
The domain verification process takes about 5-10 minutes. Copy the DNS records GoHighLevel provides and paste them into your domain registrar's DNS settings. Once verified, you'll see a green checkmark next to your domain, and you're ready to configure individual communication channels.
💡 Pro Tip
Complete domain verification first before sending any emails from GoHighLevel. This single step dramatically improves deliverability and keeps you out of spam filters—a common mistake agencies make when they skip this step.
How to Set Up Authenticated Email in GoHighLevel
Authenticated email is non-negotiable for professional outreach. GoHighLevel makes this straightforward through its email authentication system. Navigate to Settings → Email Integrations and you'll see two options: Gmail/Google Workspace or a custom SMTP connection.
For Gmail/Google Workspace users: Click "Connect Gmail Account," authorize the connection through Google's OAuth, and you're done. Your Gmail account is now authenticated within GoHighLevel. All emails sent from your account will show your Gmail address as the sender, and you'll maintain full Gmail sync.
For custom domains: If you're using a domain-based email address (like [email protected]), use the custom SMTP option. You'll need your email provider's SMTP server address, port number, and authentication credentials. Most major email providers (GoDaddy, Bluehost, Microsoft 365) publish this information in their support docs. GoHighLevel provides a helpful setup wizard that walks you through each step.
After connecting your email, test it immediately. Send a test campaign to your own email address and verify that the sender name, domain, and authentication headers appear correct. Check the email headers to confirm SPF and DKIM passes. This validation ensures your emails reach client inboxes, not spam folders.
Setting Up Phone Numbers & Call Forwarding
Phone calls are often the fastest way to convert leads. GoHighLevel's phone integration lets you make and receive calls directly from the platform, with automatic call forwarding and recording capabilities.
Go to Settings → Phone Numbers. Here you have two options: purchase a new number through GoHighLevel or port an existing number. Most agencies start with a new number for cleaner tracking and recording compliance. Click "Purchase New Number," select your desired area code and number type (local, toll-free, or vanity), then complete the purchase. New numbers are typically active within minutes.
Once your number is active, configure call forwarding to ensure you don't miss inbound calls. In the same Phone Numbers section, set your primary forwarding number (usually your cell phone or office line). You can also set up call queues, auto-responders, and voicemail transcription if needed. Enable call recording for quality assurance and compliance—this is a major advantage for agencies managing client teams.
Test your phone setup by having a colleague call your new GoHighLevel number. The call should route to your forwarding number, and you should see it logged in the Conversations tab with automatic recording.

Configuring SMS: Purchasing & Activating Your Number
SMS campaigns deliver exceptional open rates—often 98% or higher. Setting up SMS in GoHighLevel is quick and requires only a dedicated SMS-enabled phone number.
Navigate to Settings → Phone Numbers and look for the SMS option. If you already purchased a phone number in the previous step, verify it has SMS enabled (most new numbers do by default). If you need an SMS-only number without calling capabilities, you can purchase a dedicated SMS line separately.
After your SMS number is active, go to Settings → SMS Integrations to configure your SMS provider. GoHighLevel works with Twilio and other SMS gateways, but the easiest option is using GoHighLevel's native SMS service included with your number purchase. Link your SMS number here and set daily sending limits based on your plan tier.
Before launching SMS campaigns, enable compliance features. GoHighLevel automatically handles TCPA compliance, opt-in/opt-out tracking, and keyword handling (like reply "STOP" to unsubscribe). These are legally required in the US and Canada, so verify they're configured correctly in your SMS settings.
Sending Individual & Bulk SMS Campaigns
One of GoHighLevel's standout features is sending SMS directly from your Contacts tab—no need for a separate tool. To send an individual text, open any contact and click the SMS icon. Type your message, preview it, and send immediately. The conversation history appears in the Conversations tab so you can track the entire exchange.
For bulk SMS campaigns, navigate to Campaigns → SMS and create a new SMS campaign. Choose your recipient list (by tag, location, or manually selected contacts), write your message, set the send time, and launch. GoHighLevel provides real-time delivery tracking and click analytics if you include shortened URLs in your message.
Pro tip: Segment your audience before sending bulk SMS. Don't blast the same message to everyone. Create separate campaigns for different customer groups—new leads, existing clients, customers at risk of churning. Personalization dramatically improves response rates, even in short text messages.
💡 Pro Tip
Always include a clear call-to-action in your SMS messages. Instead of "Check out our new offer," try "Reply YES to claim your free consultation." SMS is not email—keep it short, specific, and action-oriented.
Managing All Communications from the Conversations Tab
The Conversations tab is the nerve center of GoHighLevel's communication system. Every SMS, email, phone call, and chat message from your contacts flows into one unified inbox. This eliminates the chaos of managing multiple platforms.
Navigate to Conversations and you'll see all inbound and outbound messages organized chronologically. Click any conversation to view the full history—emails, texts, calls, and notes all together. This contextual view prevents miscommunication and helps your team understand where each lead stands in your funnel.
Use the conversation features to stay organized: assign conversations to team members, add internal notes, tag conversations by status, and set reminders for follow-ups. You can also use the search bar to quickly find conversations by contact name, phone number, or message content.
Best Practices for Multi-Channel Communication at Scale
As your agency grows, managing multi-channel communication becomes complex. Here are proven strategies for scaling without losing quality:
1. Create communication workflows: Set up automation rules that trigger specific actions based on contact behavior. For example, if a contact opens an email, automatically send a follow-up SMS 24 hours later. If they reply to an SMS, create a task for your team to call them within 1 hour.
2. Segment aggressively: Use tags and custom fields to organize your contacts into micro-segments. Different customer groups need different messaging strategies. A new lead shouldn't receive the same SMS as a loyal customer.
3. Respect preference centers: Let your contacts choose how they want to hear from you. Some prefer email, others SMS. GoHighLevel lets you set communication preferences per contact, which improves engagement and reduces unsubscribes.
4. Monitor metrics obsessively: Track open rates, click rates, response rates, and conversion rates by channel. Email might drive more leads, but SMS might convert better. Use this data to allocate your communication budget wisely.
5. Train your team: Unified communication is only powerful if your team knows how to use it. Schedule a weekly training session on GoHighLevel's communication features. Create internal documentation on messaging standards, response time expectations, and escalation procedures.
