How to Send SMS from HubSpot: Setup Guide + Automation Tips
HubSpot is the CRM of choice for over 228,000 businesses worldwide, but it doesn't include a native way to send text messages. If you want to send SMS from HubSpot — whether it's a one-off follow-up, an automated drip, or a two-way sales conversation — you need a third-party integration to make it happen.
The good news: setting up SMS inside HubSpot takes about 15 minutes with the right tool. This guide walks you through every step, from choosing an integration to sending your first automated text. We'll also cover the automation tips that separate teams sending a few manual texts from teams running SMS at scale.
Why HubSpot Doesn't Include Native SMS
HubSpot offers email, chat, calling, and social messaging — but not SMS. The reason comes down to regulatory complexity. Business texting in the US requires TCPA compliance, 10DLC carrier registration, and opt-in/opt-out management that's fundamentally different from email marketing. Rather than build this in-house, HubSpot relies on its app marketplace ecosystem.
That's not a bad thing. Purpose-built SMS integrations like YetiConnect deliver deeper texting functionality than a built-in feature ever would — including two-way conversations, AI-powered templates, and workflow triggers that go far beyond "send a message."
Step-by-Step: How to Set Up SMS in HubSpot
Here's the complete setup process using YetiConnect as an example. The general steps apply to most HubSpot SMS integrations, though specific UI details vary by tool.
Step 1: Install Your SMS Integration from the HubSpot Marketplace
Go to the HubSpot App Marketplace, search for your chosen SMS tool, and click Install. You'll authorize the connection between HubSpot and the SMS platform. This grants the integration access to your contacts, workflows, and timeline — which is necessary for SMS to work inside HubSpot.
With YetiConnect, the installation takes under 2 minutes and doesn't require any developer involvement or API key configuration.
Step 2: Register Your Business for 10DLC
Before you can send a single text, US carriers require your business to be registered through the 10DLC (10-Digit Long Code) system. This involves:
- Brand registration — Your company's legal name, EIN, address, and website are submitted to The Campaign Registry (TCR).
- Campaign registration — You describe your SMS use case (e.g., "sales follow-up," "appointment reminders") along with sample messages and your opt-in process.
- Carrier review — Carriers assign a trust score that determines your sending throughput. Higher trust = more messages per second.
YetiConnect handles 10DLC registration directly inside the platform. Most businesses are approved within 3-5 business days. For detailed compliance guidance, see our TCPA compliance guide.
Step 3: Assign Phone Numbers to Your Reps
Each rep needs a dedicated SMS-enabled phone number. This is important: texts sent from a shared "company number" feel impersonal and get lower response rates. When each rep has their own number, conversations feel one-to-one — because they are.
In YetiConnect, you can provision local numbers (matching your prospect's area code) or port existing numbers. Each number is tied to a specific HubSpot user, so messages are automatically attributed to the right rep.
Step 4: Configure SMS Consent Properties in HubSpot
Create a custom HubSpot contact property (e.g., sms_consent_status) to track opt-in status. This property should have values like opted_in, opted_out, and not_set. Map it to your forms so that when a contact checks the SMS consent box, the property updates automatically.
This property becomes the gatekeeper for all your SMS workflows — no contact gets a text unless sms_consent_status = opted_in.
Step 5: Send Your First Text Message
Navigate to any contact record in HubSpot. With YetiConnect installed, you'll see an SMS option in the communication panel (right alongside email, call, and note). Type your message, hit send, and it appears in the contact's timeline just like an email or call log.
When the contact replies, the response appears in the same thread. Your rep can continue the two-way conversation without ever leaving HubSpot.
Step 6: Add SMS to Your HubSpot Workflows
This is where SMS goes from a manual tool to an automated channel. In HubSpot's workflow builder, YetiConnect adds a custom action called "Send SMS". You can use it anywhere you'd use a "Send email" action:
- After a form submission (instant follow-up)
- When a deal moves to a new stage
- When a contact meets a lead scoring threshold
- As a step in a multi-touch sequence (email + SMS + call)
- On a delay after a missed call
Each SMS action supports HubSpot personalization tokens ({{ first_name }}, {{ company }}, etc.) and saved templates so reps don't start from scratch every time.
Automation Tips: Getting More from HubSpot SMS
Once your integration is live, these automation strategies will help you maximize response rates and rep efficiency.
Tip 1: Use SMS for Speed-to-Lead, Email for Nurture
Research from Lead Response Management shows that responding to a new lead within 5 minutes makes you 21x more likely to qualify them. SMS is the fastest channel to hit that window. Set up a workflow that sends an automated text within 60 seconds of a form submission, then follows up with email and a call task.
Tip 2: Layer SMS into Existing Sequences
Don't replace your email sequences — augment them. A typical high-performing sequence looks like: Email (Day 1) → SMS (Day 2) → Email (Day 4) → Call (Day 5) → SMS (Day 7). Adding two SMS touches to a five-step email sequence can increase overall reply rates by 30-40%.
Tip 3: Trigger Texts from Deal Stage Changes
When a deal moves from "Proposal Sent" to "Negotiation," trigger an automated text to the decision maker: "Hi [first name], just sent over the proposal — let me know if any questions come up. Happy to jump on a quick call." This keeps momentum alive during critical deal stages.
Tip 4: Automate Appointment Reminders
No-show rates for sales meetings average 20-30%. A simple SMS reminder 1 hour before a scheduled meeting cuts no-shows by half. Use a HubSpot workflow triggered by a meeting property to automate these reminders — zero manual effort from your reps.
Tip 5: Use Smart Send Windows
SMS sent between 9-11 AM on Tuesday through Thursday sees the highest response rates. Avoid weekends and evenings — not just for compliance reasons, but because response rates drop 60% outside business hours. Most SMS integrations, including YetiConnect, let you set send windows so automated messages only go out during optimal hours.
Common Mistakes to Avoid
- Sending without consent. Every SMS must go to a contact who has explicitly opted in. Use your
sms_consent_statusproperty as a workflow filter — always. - Writing messages that sound like marketing emails. Texts should be short (under 160 characters when possible), conversational, and personalized. No subject lines, no HTML, no "Dear valued customer."
- Ignoring replies. If you send automated texts but don't monitor the inbox for responses, you'll frustrate prospects and waste the channel's biggest advantage: real-time two-way conversation.
- Over-texting. Limit automated SMS to 2-3 messages per contact per week. More than that and you'll see opt-out rates spike and carrier filtering increase.
