Journeys that react to each contact's behavior
A standalone campaign reacts to no one. Flow turns tags, segments, forms, events and lead score into step-and-branch journeys — message, wait, condition and internal actions — with consent verified before every send. For marketing and growth teams, and for agencies.

Why Flow
Mass blasting reacts to no one
The newsletter goes to everyone the same way, the campaign lives in one tool, the sign-up in another and the follow-up in a spreadsheet. Without reacting to what each contact does — and without frequency control, opt-out or a trail — communication becomes noise. Flow starts from behavior and organizes the journey by steps and branches.
One message for everyone
Without a journey, every contact gets the same thing at the same time. Those who already bought, those who went quiet and those who just arrived all land in the same blast — and engagement drops.
Isolated campaigns, no reaction
The cadence lives in one tool, the form in another and the CRM somewhere else. Nothing reacts to what the person did: the form they submitted, the segment they entered and the score that changed all go unnoticed.
Communication without governance
Without frequency control, per-channel opt-out and a trail of every send, communication drifts toward spam and becomes hard to audit later.
What Flow does
From the trigger to the internal action — organized by steps and branches
Flow turns behavior into a journey and the journey into action, without relying on a manual blast.
Journey builder by steps and branches
Chain trigger, wait, condition and internal actions — move stage, adjust score, update field, apply or remove tag, webhook, notify the team. It is a step-and-branch builder, not a drag-and-drop canvas.
Behavior-based triggers
Start the journey from a tag applied, a segment entered or exited, a form submitted, a custom event, a score band change or a manual start — seven triggers, and each one has something that actually produces it.
Contacts, segmentation and lead scoring
Manage contacts with fields and import, create dynamic segments (AND/OR) that recalculate on their own, and score interest with lead scoring.
Campaigns with audience and throttling
Estimate the audience by list or segment, freeze it before sending, split it into A/B variants, throttle the send rate and schedule it. No unlimited volume promised: every plan states its cap.
Conversion: forms and pop-ups
Capture leads with forms, pop-ups and the WhatsApp button, installed on your own site with a code snippet. Consent is recorded on the back end, and the submission becomes a contact and a journey trigger right away.
Results by source
Funnel, conversions and attribution show where each contact came from and what they did next. Events live in their own catalogue, and the base exports whenever you want — the data is yours.

Get to know FlowChannels
One proven channel, one with assisted activation
Email is the channel Flow sends on today, from your own verified domain. WhatsApp uses the official Meta API and depends on your account and approved templates — so it comes with assisted activation, not a toggle.
Sending today
Comes in as a step inside the journey builder, alongside waits, conditions and internal actions.
Email (Resend) — marketing and transactional
Sending under your own sender identity, with the domain verified. One-click unsubscribe with the standard header, a suppression list honoured on every send, and consent verified before anything leaves.
With assisted activation
Exists in the product and must be activated before it sends. WhatsApp and SMS use your own provider account and are contracted separately, as a message package; web push depends on the visitor opting in. Activation is done together with the team.
WhatsApp — official Meta API
Sending via the official API (Meta Cloud), with your own account. Requires the contact's opt-in for marketing and templates approved by Meta; there is keyword opt-out and suppression. Never free-form blasting without opt-in.
SMS (Twilio) — the client's account
Sending via Twilio with the client's own account (BYO). Requires opt-in and suppression; sending is paid by you, directly to the provider. Not a step in the visual journey.
Web push (VAPID) — browser
Push notification in the browser (Web Push, VAPID standard), with quiet hours and a frequency cap. It is web push — not native mobile app push.
To be direct: email is the channel that has already sent real messages in production. WhatsApp has the integration ready and no account configured so far — hence the assisted activation. SMS and web push exist in the code but are not part of the offer: they have never been switched on, and we do not sell what has never run.
In action
From the trigger to the result recorded in the trail
An illustrative example of the real Flow — it includes verifying consent and suppression before any send. No real account, data or brand, and never a send without consent.
From trigger to result, step by step
IllustrativeTrigger
A form submitted or an event starts the contact's journey.
Contact segmented
The contact enters the right segment based on behavior and data.
Consent verified
Before sending, Flow checks consent and suppression. Without it, no send.
Message sent
The message goes out by email, from a sender on your own domain.
Wait
A wait respects the contact's timing before the next step.
Signal recorded
What the contact does on your site becomes an event and adjusts their score.
Branch
A condition decides the next path based on behavior.
Internal action
An internal action runs: tag, field, lifecycle stage or a notice to the team.
Result recorded
What happened is recorded in the trail of every send.
Flow: a trigger (form submitted or event) starts the journey; the contact is segmented; consent and suppression are checked before sending (control point); the message goes out by email; a wait respects the contact's pace; a new signal from the contact adjusts their score; the condition branches the path; an internal action runs (tag, field, stage or team notice); the outcome is recorded in the trail.
Use cases
Where Flow fits day to day
Four common journeys Flow organizes by steps and branches, with send governance.
Onboarding that activates
A sequence guides the new contact to first value and stops once they've activated — without repeating a message for those who already moved on.
Nurture and re-engagement
Cadences that react to behavior: those who clicked follow one path, those who went quiet another, with frequency controlled per contact.
Transactional by event
Confirmations, reminders and notices triggered by event, over email, with a trail of every send.
Handover to the sales team
When the contact's score crosses the band you set, the journey moves their stage, applies the right tag and notifies the team — with nobody having to watch a spreadsheet.
Consent and governance
Send-governance tools — not automatic compliance
Flow brings real controls so communication goes out with governance. They are support tools: consent is an option per workspace, and legal responsibility remains yours.
Consent per workspace
When consent is required, Flow verifies and records it before sending. It is configurable per workspace — not automatic data-protection compliance.
Per-channel opt-out and suppression
One-click email unsubscribe, using the standard header email clients recognise, and a suppression list honoured before every send.
Quiet hours and frequency cap
Quiet hours (global and per channel) and a weekly frequency cap per channel prevent over-messaging the same contact.
A trail of every send and kill switch
Every send is recorded for audit, and a kill switch lets you stop communication when needed.
These are tools to support communication governance. They help you honor consent and opt-out, but they do not replace your privacy policy or guarantee automatic legal compliance.
Where Flow starts and stops
Flow, Link and Orbit solve different things
A prose positioning to place Flow — it is not an official comparison or an integration. Each one handles a different part of the operation.
Automates journeys and actions by trigger and condition
Flow starts from the contact's behavior and organizes the journey by steps and branches: message, wait, condition and internal actions, with send governance.
Centralizes conversations and channels
Link brings conversations and support channels together in an inbox. Flow automates communication by behavior; they are distinct roles.
Organizes contacts, deals and pipeline
Orbit is the CRM for deals and pipeline. Flow handles communication automation; each holds a different kind of data.
This is positioning, not an official comparison or an integration. Today there is no confirmed data integration between Flow and Link or Orbit. If your operation depends on a connection between systems, talk to us before contracting.
For agencies
Multi-client operation, with enablement
Flow was designed for those who run many clients at once — each in its own environment, without mixing data.
Multi-workspace
Manage several client environments, with members, blueprints and a directory, from an agency operation.
Each client isolated
Each client has its own workspace, contacts and journeys. Serve many accounts without mixing data.
Operation with enablement
The agency operation is sold with enablement, not as turnkey resale. End-to-end branding and financial pass-through are not available yet.
The agency operation requires enablement — it is not turnkey resale. End-to-end branding (white-label) and financial pass-through between agency and client are not available yet.

Add-on channels
WhatsApp and SMS are bought separately
No Flow plan includes WhatsApp or SMS — not even Enterprise. To send on those channels you buy the add-on, and keep paying your Flow plan as usual. The reason is simple: email is something Centriu buys and resells inside your cap; WhatsApp and SMS messages come out of your own provider account, and charging for them here would be charging you twice.
You connect your own WhatsApp Cloud API number. Flow handles templates, the 24-hour window, opt-out and delivery status.
- Up to 5,000 messages/monthR$ 197/mêsGet it
- Up to 25,000 messages/monthR$ 497/mêsGet it
- Up to 100,000 messages/monthR$ 997/mêsGet it
The provider account is yours: Meta (WhatsApp Cloud API). Meta bills you per message directly, and also caps your number with a tier. The cap that applies is the lower of the two — buying 100,000 for a TIER_250 number buys nothing.
SMS
You connect your own Twilio account. Flow normalises the phone number, honours keyword opt-out and records delivery.
- Up to 2,000 segments/monthR$ 97/mêsGet it
- Up to 10,000 segments/monthR$ 297/mêsGet it
- Up to 50,000 segments/monthR$ 697/mêsGet it
The provider account is yours: Twilio. Twilio bills you per message segment, directly. Accented text uses more segments — Flow shows how many before you send.
What you pay here is the platform around the send: opt-in and keyword opt-out, suppression list, approved templates, the 24-hour window, delivery status, automation and the record of all of it. The send itself is billed by the provider, on their invoice, at their price. Two bills — and we would rather say so on the pricing page than let you find out on your first campaign.
Questions
Frequently asked questions
Is Flow an automation platform?
Yes. Flow is Centriu's platform for marketing automation and lifecycle journeys. It turns triggers (tag, segment, form, event, score) into step-and-branch journeys — with message, wait, condition and internal actions — plus contacts, segmentation, lead scoring, campaigns and conversion. The builder is by steps and branches, not drag and drop.
Which triggers are there?
Seven, and each one has something that actually produces it: tag applied, segment entered, segment exited, form submitted, custom event, score band change and manual start. A trigger with no producer is not offered in the editor — it would create a journey that never starts.
Which channels can I use?
One in operation and one with assisted activation. Email (Resend, with your verified domain) is the channel Flow sends on today and is the message step of the journey. WhatsApp uses the official Meta API, with your own account, contact opt-in and approved templates — activation is done with our team. SMS and web push exist in the code but are not part of the offer.
Does Flow send WhatsApp?
Yes, via the official WhatsApp API (Meta Cloud) — with an honest caveat: the integration is ready and no account has been configured to date. That is why activation is assisted rather than a toggle. It requires your Meta account, the contact's opt-in for marketing and approved templates; there is keyword opt-out and suppression.
Does Flow send email?
Yes — marketing and transactional, via Resend, from a verified sender domain. What goes out is recorded in the send trail, with one-click unsubscribe and a suppression list. What is NOT part of the offer today is the delivery, open and click report: the provider callback is not yet wired to Flow, and we do not sell a metric we do not measure. We promise neither guaranteed delivery nor unlimited volume.
Does Flow create landing pages and forms?
Forms and pop-ups, yes — and the WhatsApp button. You install them on your own site with a code snippet, consent is recorded on the back end, and the submission becomes a contact and a journey trigger right away. A landing page hosted by Flow is NOT part of the offer: page authoring is not done in the product yet, and an empty page serves no one.
How does consumption work?
By two numbers, and both appear on the plan card: how many contacts fit in your base and how many emails you send per month. The contact is what the platform stores; the email is what it spends. Both are genuinely counted — contacts by direct count, emails by a record written in the database on every send.
What happens if I go over the limit?
You are warned from 80% of the monthly cap, on the Plan & Usage screen. At 100%, new sends stop until the month turns over or you move up a plan — there is no automatic overage charge, because there is no automatic charging in the product at all today. We would rather stop and tell you than raise an invoice you did not choose. There is no "unlimited email" here: every email has a real cost, and a plan pretending otherwise is charging someone the wrong price.
What is the difference between Flow, Link and Orbit?
Flow automates journeys and actions by trigger and condition. Link centralizes conversations and channels in an inbox. Orbit organizes contacts, deals and pipeline (CRM). They are different roles — and, today, with no confirmed data integration between them.
How is consent handled?
When required, consent is verified and recorded before the send, configurable per workspace. There is per-channel opt-out (one-click email unsubscribe and a keyword on WhatsApp), quiet hours, a frequency cap and a kill switch. These are governance support tools — not automatic legal compliance.
Can agencies operate Flow for clients?
Yes. Flow has multi-client management (multi-workspace), with environments, members and blueprints per client. The agency operation is sold with enablement, not as turnkey resale; end-to-end branding and financial pass-through are not available yet.
Is there an implementation?
Yes. Onboarding is assisted: kick-off, email domain verification, installing the tracking snippet and forms on your site, and building the first journey together with you. If WhatsApp is in scope, the Meta account and templates are configured in that same step. Marketing, growth and CX teams run Flow day to day.
