WhatsApp on HubSpot, compared honestly.

Flowella turns your HubSpot forms into WhatsApp Flows and writes each completed one back as a HubSpot form submission. Respond.io is a team inbox for WhatsApp, TikTok, Instagram and more, with AI agents and its own workflows. Both connect to HubSpot. They’re built for different jobs.

The same answers, two ways.

Ask three questions in a WhatsApp Flow and the answers land in HubSpot as properties, ready for a workflow. Ask the same three in a chat and you get messages someone has to read and retype. Try both and watch the record.

Three tools, three jobs.

Pick by the job you need done. HubSpot’s own WhatsApp channel is the third option, and for some teams it’s enough.

    • Your team replies in HubSpot, or in a focused WhatsApp inbox.

    • Message details in conversation properties are all your workflows need.

Questions teams ask.

Four questions HubSpot teams put to us, answered for both tools.

Can a completed WhatsApp form start a HubSpot workflow?

Flowella

Yes. Each completed Flow arrives as a native HubSpot form submission, with the answers on contact properties, so form-submission enrolment works as it does for web forms. Flowella adds a Form Completed trigger too. Workflows need HubSpot Professional or Enterprise.1618

Respond.io

Respond.io doesn’t create WhatsApp Flows, though it can send Flow templates built in Meta. Its HubSpot app syncs HubSpot contact properties into Respond.io, where your team can view and edit them; its automations run in Respond.io’s Workflows.42

Can our team reply from the HubSpot inbox?

Flowella

Yes. Connect the Flowella channel and WhatsApp threads land in the HubSpot conversations inbox, beside email, chat and calls. It needs Sales Hub or Service Hub, Professional or Enterprise, and HubSpot Credits may apply. The Flowella app inbox works on any plan.1920

Respond.io

Replies happen in Respond.io’s own inbox, with the contact’s HubSpot properties in the sidebar and a link to open the record in HubSpot.2

Do we have to give up the WhatsApp Business App?

Flowella

No. Flowella supports coexistence: keep the app for one-to-one chats while Flows and templates run on the same number.21

Respond.io

No. Respond.io supports coexistence too: keep using the app while Respond.io runs automation on the same number, though past chats don’t sync.7

What would a seven-person team sending 25,000 templates a month pay?

Flowella

Pro is $199 a month with 2,500 billable messages, then $0.04 each. Meta bills its own fees to you, at its list rate.1412

Respond.io

HubSpot needs Growth or above. Growth is $159 a month billed yearly ($199 monthly) for 10 users and 1,000 monthly active contacts. Broadcasts don’t count, but contacts you chat with do, and more cost more: 10,000 is $449 a month billed yearly. Meta’s fees come on top, with no markup.165

Ratings and reviews.

Respond.io’s HubSpot app has two ratings so far, too few to judge it by, so read the reviews from teams doing the job you have.

Is this comparison fair?

We’ve tried to make it so. Every fact about Respond.io links to its own pages or its HubSpot Marketplace listing, checked on 16 October 2026. Respond.io does more than Flowella in places, such as channels beyond WhatsApp, AI agents and other integrations, and the table says so. Its prices depend on how many contacts you talk to each month, so we give them in words rather than in a calculator.

Can Respond.io turn a HubSpot form into a WhatsApp Flow?

No. Respond.io’s help centre says WhatsApp Flow creation isn’t supported, though Flow templates built in your Meta Business Portfolio can be synced and sent. Flowella starts from the HubSpot form you already have. Source 4, source 17.

Who bills WhatsApp’s message fees?

With Flowella, Meta bills you directly, at Meta’s list rates, and Flowella never marks them up. Flowella’s own bill is your plan plus any billable messages over its allowance.

With Respond.io, you top up WhatsApp credit in Respond.io, and Respond.io says it adds no markup to Meta’s rates. Its subscription is billed separately. Source 15, source 12, source 5, source 1.

Which plans connect to HubSpot?

Every Flowella plan, from Starter. Forms to Flows works on every HubSpot plan, Free included; Flowella’s workflow actions need HubSpot Professional or Enterprise. Respond.io’s help centre and pricing page put HubSpot on Growth and above, though its Marketplace listing also names Starter. Source 16, source 18, source 2, source 1, source 3.

What is a monthly active contact?

Respond.io counts a contact who sends or receives a message, except in a broadcast, or makes or takes a call in the billing month. Growth and Advanced start with 1,000 a month; above your tier, Respond.io bills $12 per 100 on Growth and $15 on Advanced. Flowella prices by billable message, not by contact. Source 6, source 1, source 14.

What about data residency for UK and EU buyers?

Flowella hosts Starter and Pro customers in Microsoft Azure’s UK South region, in London, and Enterprise customers can be hosted elsewhere by arrangement. Respond.io’s sub-processor list names Amazon Web Services for hosting but not a region; the controller in its privacy policy, Rocketbots Limited, gives an address in Hong Kong. Whichever you choose, check the vendor’s data processing terms. Source 24, source 11, source 10.

What is Respond.io best at?

A team inbox for WhatsApp, TikTok, Instagram, Messenger, Telegram, LINE, WeChat, Viber, email and calls; AI agents that answer, route and qualify; workflows and broadcasts; and tools for Meta and TikTok ads. If that’s your job, Respond.io is built for it. Source 1, source 8.

Can we use Flowella alongside Respond.io?

Yes, on different numbers. Each WhatsApp number sits with one provider at a time, and moving a number from one to the other is a migration. Source 26.
