Can you send SMS from HubSpot without Marketing Hub?
HubSpot's own SMS add-on needs Marketing Hub Professional or Enterprise. A Twilio number connected as a custom channel does not, and works on Sales Hub.
Yes. HubSpot’s native SMS is part of Marketing Hub, but it isn’t the only way to get SMS into the CRM. Connect a Twilio number as a custom conversations channel and you get two-way texting inside HubSpot without a Marketing Hub subscription anywhere in the picture.
The two routes solve different problems, and picking the wrong one is an expensive mistake.
What HubSpot’s own SMS requires
Per HubSpot’s documentation, the Marketing SMS add-on needs a Marketing Hub Professional or Enterprise subscription before you can buy it. The add-on itself is priced separately on top.
There are geographic limits too. Messages send only from US-based numbers. If you register a 10DLC number, you can only send to US and Canada numbers. Sole proprietors are not supported at all.
None of that makes it bad. It’s built for marketing SMS: segmented sends, subscription types, workflow automation, opt-in management. If that’s the job, it’s the right tool and the Marketing Hub requirement is the price of admission.
But plenty of teams don’t want marketing SMS. They want a rep to answer a customer’s text inside the CRM.
What the Twilio route requires instead
A custom conversations channel needs Sales Hub or Service Hub Professional or Enterprise. That’s a different product line from Marketing Hub, and most teams doing sales or support already sit on one of those.
You bring your own Twilio account and number. TryWired charges for the channel, Twilio charges you directly for the messages and carrier fees. There’s no per-seat and no per-message markup in between.
The practical difference:
| HubSpot Marketing SMS | Twilio as a custom channel | |
|---|---|---|
| HubSpot subscription | Marketing Hub Professional or Enterprise | Sales Hub or Service Hub Professional or Enterprise |
| Built for | Campaigns, segmented sends, workflows | Two-way conversations with individual contacts |
| Sending numbers | US-based only | Any number Twilio supports |
| Recipients | US and Canada on 10DLC | Wherever your Twilio account is provisioned |
| Sole proprietors | Not supported | Supported |
| Message cost | Bundled into the add-on | Billed by Twilio at their rates |
| Lands in | Marketing tools | The conversations inbox, beside email and chat |
Which one you actually want
Ask what the message is.
If it goes to a list, it’s marketing SMS. Subscription types, unsubscribes, and campaign reporting matter, and Marketing Hub gives you those natively.
If it goes to a person, it’s a conversation. A support agent answering a question, a rep chasing a renewal, an account manager confirming a delivery. Those belong in the shared inbox where the rest of that customer’s history already lives, and they don’t justify a Marketing Hub subscription on their own.
The second case is the one that gets solved badly. Teams end up texting from personal phones, or paying for Marketing Hub Professional to send what amounts to one-to-one messages, or copying threads into notes by hand.
What you get on the conversation route
Each connected Twilio number points at a HubSpot conversations inbox you choose, so support numbers and sales numbers stay separate.
Contacts match on the E.164 phone number. An existing record gets reused, and a new one is created only when nothing matches.
Replies from HubSpot go back through the original Twilio number, and direction and timestamps stay accurate on both sides. MMS media moves with the thread for numbers that support it.
Every exchange logs as HubSpot communication activity, associated with the contact and with the companies and deals already linked to it, so your existing reports pick it up without new configuration.
And you can start the conversation from the contact record rather than waiting for an inbound message.
What it won’t do
It isn’t a campaign tool. There’s no segmentation, no subscription type management, no send scheduling. If you need those, you need Marketing Hub, and this doesn’t substitute for it.
It doesn’t remove compliance work. A2P 10DLC registration, STOP handling, and consent records are still yours to manage in Twilio and in your own process. Twilio holds the carrier relationship, so Twilio is where those settings live.
And it doesn’t get you around the HubSpot plan requirement entirely. Custom channels need Professional or Enterprise on Sales Hub or Service Hub. Starter and the free CRM cannot accept one, and no integration can work around that.
