Why a tool for HubSpot SMS integrations?

It's well known how SMS is one of the most effective channels to reach people (55% read rates and 100% "view rates").

So it can be a solid channel for initiatives such as client acquisition, webinar reminders, or abandoned cart recovery.

But if you're a HubSpot user and also want to use SMS, you may have run into issues like this:

Need for a specialized HubSpot SMS integration tool (Source: Reddit)

Manually logging SMS in HubSpot is a time-waster. So, maybe automate it with Zapier or Make?

Well, you can. But you might end up setting up webhooks or APIs. That's already too technical for most people. And it only solves a small piece of the puzzle.

HubSpot users still face some core limitations when it comes to SMS:

TL; DR: Key limitations of SMS in HubSpot

HubSpot SMS issue 1: compliance and opt-in management

The problem

SMS is highly regulated. Laws like TCPA (US), GDPR (EU), and CASL (Canada) require businesses to get explicit, documented consent before texting anyone.

Even transactional messages can fall under scrutiny, depending on content and context.

Why it's an issue

HubSpot doesn't natively track SMS-specific consent. You can use custom properties or checkboxes on forms. But that doesn't always sync cleanly.

Worse case? Some integrations don't validate consent at all. That leaves you at risk of sending texts to non-opted-in contacts.

You might also need to manage country-specific rules (e.g., double opt-in in Germany). Unfortunately, HubSpot workflows aren't built to handle those by default.

HubSpot SMS issue 2: limited native SMS support

Problem

HubSpot's built-in SMS features are either minimal or completely missing, especially on lower-tier plans. For anything beyond basic notifications, you'll need external tools.

Why it's an issue

With third-party apps, you risk data falling out of sync with your CRM. And even when integrations exist, they're not always "native."

Some apps don't fully embed into HubSpot's UI. This limits how you can trigger messages, log activity, or use CRM data for targeting.

💡 A proper HubSpot SMS integration should feel seamless, built to sync contacts, trigger texts from workflows, and log message history inside contact records. Mobile Text Alerts offer this kind of native-like functionality without the dev lift.

Adaptive group for scheduled messages

HubSpot SMS issue 3: personalization and segmentation gaps

The problem:

SMS messages must be timely. Otherwise, users will opt out fast.

Mindy Regnell, Head of Market Intelligence at Klaviyo, puts it this way:

“

Send your SMS subscribers messages regularly. If you don't, they are likely to forget that they signed up for texts. This can drive up unsubscribe rates and the chances of your texts being flagged as spam.

Mind you, the problem is more than timing and frequency. Relevance is just as critical.

The 2024 Global Texting Takeaways report that:

• 53% of users opt out of texts due to irrelevant messages
• That figure jumps to 61% when messages feel excessive

Lack of personalization (Source: 2024 Global Texting Takeaways)

Unfortunately, there are no fixes to personalization with just HubSpot.

Why it's an issue

HubSpot's email tools have personalization options, like dynamic tokens and list segmentation. But many SMS integrations don't bring that same power to texting. You might be stuck with generic messages or limited merge fields.

With the right external tool, you can do deep personalization, like logic-based workflows.

💡 Mobile Text Alerts, for example, allows teams to automate SMS workflows within HubSpot. You can access even more personalization features in-MTA with a dedicated Workflow Builder.

How to create an SMS workflow

Bottom line:

A dedicated HubSpot SMS integration tool ensures messages are timely, compliant, and personalized without derailing your workflows. Such tools save time, reduce churn, and keep your CRM clean.

But which one can support real-world use cases? Let's find out.

3 tools for robust HubSpot SMS integrations

These three tools integrate SMS into HubSpot, helping you automate texts, manage replies, and stay compliant. Each has its strengths and tradeoffs.

TL; DR: Quick comparison

Now, let's break them down one by one.

Sakari

Sakari is a cloud-based SMS platform built to bridge SMS and HubSpot workflows. With it, marketing and sales teams can send, log, and manage both 1:1 and mass SMS from within the HubSpot CRM without switching platforms.

Capabilities:

• Send SMS via contact records, workflows, or Conversations Inbox
• Supports only "basic" personalization and templates
• Delivery tracking, message logging, and number management
• Includes international support (e.g., UK)

For who:

Works for individuals/teams who send event reminders, follow-ups, or transactional messages from HubSpot. It is commonly used in agencies, higher-ed institutions, and SMBs looking for integrated 2-way texting.

Limitations:

Sakari works best once configured, but setup can be tricky.

• Common issues include contact syncing, list imports, and configuring inboxes inside HubSpot.
• Also, compliance tracking is limited.
• Lastly, personalization options don't match HubSpot's native email tools.

In short, Sakari lacks complex logic, segmentation, or tagging features unless you add custom workarounds.

Salesmsg

Salesmsg is a two-way business texting and calling platform that integrates with HubSpot. It allows teams to send SMS and MMS messages within HubSpot.

Overall, it streamlines communication workflows and makes managing follow-ups and nurturing leads easy.

Capabilities:

• Send one-on-one or bulk SMS/MMS from within HubSpot
• Automate texts using HubSpot workflows and sequences
• Track all messages and calls in HubSpot contact records
• Access via desktop or mobile without using personal numbers

For who:

Works for sales, support, and account management teams who need fast, trackable communication inside HubSpot. It automates follow-ups, reduces admin time, and boosts engagement rates.

Limitations:

Salesmsg excels at 1:1 messaging and basic automation. More complex segmentation or complex SMS branching logic needs workarounds.

Some users also note that its shared inbox setup can be a bit confusing. It is even more so for larger teams managing several reps or phone numbers.

Mobile Text Alerts

Mobile Text Alerts is a fully integrated SMS platform. Whether in-platform or in-HubSpot, businesses use it to manage SMS communications. It streamlines customer engagement through one-on-one texting, automated workflows, and SMS activity tracking.

Hence, it's ideal for teams seeking simple, scalable SMS integration.

Capabilities:

• 1-on-1 SMS conversations with HubSpot contacts
• Automated SMS workflows directly within HubSpot
• Instant syncing with HubSpot's contact list
• Customizable SMS automation and tracking in HubSpot timelines

For who:

Mobile Text Alerts is ideal for businesses of all sizes, particularly those who want to integrate SMS directly into HubSpot workflows. It works for sales teams, customer support teams, and marketers who need to streamline communication and automate SMS campaigns.

Limitations:

Teams seeking highly complex segmentation or dynamic message flows can't do so within HubSpot, but they can do it within the MTA dashboard.

Verdict: Which tool should you use?

💡 Unlike other tools that rely heavily on external dashboards or limited sync, MTA brings one-on-one messaging, automated workflows, opt-in tracking, and activity logging entirely into HubSpot. It's the most seamless way to manage SMS campaigns without leaving your CRM.
