Which is the right fit for your HubSpot stack?

We’ve tried to make it so. Every fact about HelloSend links to its own pages or its HubSpot Marketplace listing, checked on 25 October 2026. HelloSend does more than Flowella in places, such as SMS and calls, reps’ own WhatsApp, AI replies and other CRMs, and the table says so. Its pages give two sets of prices for HubSpot, and it doesn’t publish a rate for messages over your credits, so we give prices in words rather than in a calculator.

HelloSend’s site and help centre don’t describe WhatsApp Flows. It sends one-to-one messages, campaigns and automated messages, with templates you create and get approved in Meta’s Business Manager. Flowella starts from the HubSpot form you already have. Source 7, source 6, source 19.

HelloSend’s pricing page lists a Standard plan at $75 a month, or $60 a month billed yearly ($720 a year), for 3 users and 10,000 messages a month, then $25 a user; 5 users get 16,000 messages and 10 get 31,000. If you ask, there are 1-user and 2-user plans at $45 and $60 a month. Its help centre says you subscribe from that page after installing from a CRM marketplace.

Its HubSpot page and Marketplace listing show other plans: SMS at $5 and SMS + WhatsApp at $10 a user a month, with 1,000 messages; the listing says its prices were last updated in August 2025. Ask HelloSend which applies to you. Prices are in US dollars, before tax, as published on 25 October 2026. Source 1, source 13, source 2, source 3, source 11.

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 HelloSend, Meta’s fees are billed separately from HelloSend’s subscription, and HelloSend says it adds no hidden markup. Its WhatsApp FAQ adds that further fees may apply for automation, campaigns or high-volume messaging. Messages also count toward your HelloSend plan’s monthly messages.

Yes. Scan a QR code and HelloSend links personal WhatsApp or the WhatsApp Business App as a linked device, with no API approval; HelloSend says to keep the phone online. It also connects WhatsApp Business numbers through Meta’s API, which needs a Facebook Business account and a dedicated number. Flowella connects WhatsApp Business Accounts through Meta’s platform. Source 5, source 3, source 4, source 24.

Every Flowella plan, from Starter. Forms to Flows works on every HubSpot plan, Free included; Flowella’s workflow actions need HubSpot Professional or Enterprise. HelloSend’s Marketplace listing says its features work with HubSpot Free, and its help centre says its automation needs HubSpot workflows, typically on Professional or Enterprise. Source 18, source 20, source 3, source 4.

Flowella hosts Starter and Pro customers in Microsoft Azure’s UK South region, in London, and Enterprise customers can be hosted elsewhere by arrangement. HelloSend’s privacy policy says personal data is stored on servers in the United States, and its Marketplace listing says it runs on AWS and is ISO 27001 and SOC 2 certified. Whichever you choose, check the vendor’s data processing terms. Source 26, source 12, source 3.

SMS, WhatsApp and calls from inside the CRM: one-to-one messages from HubSpot records, bulk campaigns to HubSpot lists, drips from HubSpot workflows, a shared inbox, reps’ own WhatsApp linked by QR code, and the same tools in Zoho, Pipedrive, Salesforce and more. If that’s your job, HelloSend is built for it. Source 3, source 4, source 7.

Yes, on different numbers. Each WhatsApp Business Platform number sits with one provider at a time, and moving a number from one to the other is a migration. HelloSend’s SMS, and WhatsApp linked by QR code, don’t use a Business Platform number. Source 28, source 5.
