Connect Brevo to Acuity Scheduling
Automatically sync data from Brevo into Acuity Scheduling. Ikaroa designs, builds and maintains a reliable Brevo → Acuity Scheduling integration so your tools stay in perfect sync.
TL;DR
Connecting Brevo to Acuity Scheduling lets you automatically move subscribers, campaigns and email events from Brevo into Acuity Scheduling, so your team stops copying data by hand. Brevo is email, SMS and marketing automation (formerly Sendinblue); Acuity Scheduling is online appointment scheduling by Squarespace. The integration can be built with a native connector, a tool like Zapier or Make, or a custom API integration for full control. Ikaroa builds and maintains the connection for you.
How do you connect Brevo to Acuity Scheduling?
You can connect Brevo to Acuity Scheduling in three ways: a native integration if one exists, a no-code automation platform such as Zapier or Make, or a custom API integration built directly against the Brevo and Acuity Scheduling APIs. The right choice depends on data volume, how real-time the sync needs to be, and how much custom logic you require. For business-critical or high-volume syncs, a custom API integration is the most reliable. Ikaroa designs, builds and maintains Brevo → Acuity Scheduling integrations end to end.
Teams that rely on both Brevo and Acuity Scheduling usually hit the same wall: the two tools don't talk to each other. Brevo handles running email and lifecycle marketing campaigns, while Acuity Scheduling is used for booking meetings and managing appointments. Without an integration, someone ends up exporting spreadsheets, re-keying records and reconciling mismatches by hand, which is slow, error-prone and doesn't scale. A proper Brevo to Acuity Scheduling integration removes that friction by keeping data flowing automatically from one system to the other.

Ways to connect Brevo and Acuity Scheduling
Native integration
If Brevo and Acuity Scheduling offer an official connector, this is the quickest path. It covers common fields out of the box, but native connectors are often limited in which subscribers and campaigns they sync and how much you can customise the mapping.
Best for: simple, standard use cases with low data volume
No-code automation (Zapier / Make)
Tools like Zapier and Make connect Brevo and Acuity Scheduling with visual workflows. Great for getting started fast and for moderate volumes, though per-task pricing and rate limits can add up, and complex logic gets hard to maintain.
Best for: moderate volume and quick wins without engineering
Custom API integration
A bespoke integration built directly against the Brevo and Acuity Scheduling APIs gives you full control: exact field mapping, custom business logic, real-time webhooks, error handling and retries. This is what Ikaroa builds for business-critical syncs that need to be reliable at scale.
Best for: high volume, real-time, business-critical syncs and custom logic

Brevo to Acuity Scheduling integration FAQ
How do I connect Brevo to Acuity Scheduling?
There are three main ways to connect Brevo to Acuity Scheduling: a native integration (if available), a no-code automation tool like Zapier or Make, or a custom API integration built against the Brevo and Acuity Scheduling APIs. For occasional, simple syncs a no-code tool is fine; for reliable, high-volume or real-time syncing of subscribers and campaigns, a custom integration is best. Ikaroa can build and manage it for you.
Can I sync Brevo and Acuity Scheduling in real time?
Yes. Using webhooks from Brevo, changes can be pushed to Acuity Scheduling within seconds instead of waiting for a scheduled batch. Real-time syncing is best handled with a custom API integration, which Ikaroa builds with proper retries and error handling so nothing is lost.
What data can I sync between Brevo and Acuity Scheduling?
Commonly synced data includes subscribers, campaigns, email events and lists. The exact fields depend on your setup. Ikaroa maps your Brevo data to the right objects in Acuity Scheduling and handles any transformations needed in between.
Do I need Zapier to integrate Brevo with Acuity Scheduling?
No. Zapier or Make are convenient for simple automations, but they are not required. A direct, custom Brevo to Acuity Scheduling API integration avoids per-task fees and rate limits, and gives you more control over reliability and logic. Ikaroa builds both no-code and custom integrations depending on what fits your needs.
How much does a Brevo to Acuity Scheduling integration cost?
It depends on complexity: a simple one-way sync of subscribers and campaigns is far cheaper than a real-time, two-way integration with custom logic. Ikaroa scopes the work up front and gives you a fixed quote. Get in touch for a tailored estimate for your Brevo → Acuity Scheduling integration.
Is the Brevo Acuity Scheduling integration secure?
Yes. We connect to Brevo and Acuity Scheduling using their official APIs with OAuth or scoped API keys, never store credentials in plaintext, and follow least-privilege access. All data in transit is encrypted, and we can host the integration in your own cloud if required.
