Flowella
HubSpot forms as WhatsApp Flows
Flowella turns your HubSpot forms into WhatsApp Flows and writes each completed one back as a HubSpot form submission. Sinch Engage sends SMS, MMS, RCS and WhatsApp from HubSpot workflows and its own team inbox. Both connect to HubSpot. They’re built for different jobs.
Two good tools. Which job is yours?

Partly means the tool does some of this, as the line explains. Prices are in US dollars, before tax.
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.

Answer in the Flow first, then try the chat.
Answer in the Flow first, then try the chat. The Flow caught that. Fix it and send again. Three answers, three clean properties. Now give the same answers in a chat. Each reply lands as a message, not a field. Same answers. Someone has to read these. Same answers. Only one set is ready to use.

Sinch Engage is a good product, and in places it does more than Flowella. Here’s who each one is.
Flowella turns HubSpot forms into WhatsApp Flows and writes each answer back to HubSpot. It’s from the team at Discover Digital, a HubSpot Platinum Partner.
Sinch Engage, formerly MessageMedia, is the business messaging platform from Sinch, which started in 2008. It sends SMS, MMS, RCS and WhatsApp from one inbox and from tools such as HubSpot.
Pick by the job you need done. HubSpot’s own WhatsApp channel is the third option, and for some teams it’s enough.
Three jobs. Pick yours.

We’ve tried to make it so. Every fact about Sinch Engage links to Sinch’s own pages or its HubSpot Marketplace listing, checked on 16 October 2026. Sinch Engage does more than Flowella in places, such as SMS, RCS and other channels, AI agents and CRMs beyond HubSpot, and the table says so. Its prices depend on where your business is based, so we give them in words rather than in a calculator.
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 Sinch Engage, each WhatsApp message carries Meta’s fee and a separate Sinch fee, and both appear in your Sinch usage. The social channels add-on includes 1,000 messages a month, then the Sinch fee is $0.05 a message in the US and £0.045 in the UK. Source 20, source 17, source 2, source 1.
Sinch prices Engage by where your business is based. In the US, plans run from Basics at $99 a month billed annually ($119 monthly) to Advanced at $2,399, each with an SMS allowance and 1 to 3 users. In the UK, from Basics at £35 a month to Advanced at £879. WhatsApp is an add-on on every plan. Source 1.
Every Flowella plan, from Starter. Forms to Flows works on every HubSpot plan, Free included; Flowella’s workflow actions need HubSpot Professional or Enterprise. Sinch’s HubSpot app works with every Sinch Engage plan, from Basics, and WhatsApp needs its social channels add-on. Source 21, source 23, source 3, source 1.
Flowella hosts Starter and Pro customers in Microsoft Azure’s UK South region, in London, and Enterprise customers can be hosted elsewhere by arrangement. Sinch’s sub-processor list names Amazon Web Services hosting for Sinch Engage in Ireland and in Australia, and Sinch Engage is provided in Europe by Sinch Sweden AB. Whichever you choose, check the vendor’s data processing terms. Source 29, source 16, source 3.
Yes. Sinch Engage can carry your SMS and RCS while Flowella runs WhatsApp Flows. For WhatsApp itself, each number sits with one provider at a time, and moving a number from one to the other is a migration. Source 31.
