How to connect Klaviyo and Notion in 3 steps

Whalesync doesn't just connect Klaviyo and Notion; it syncs them. Simple connections are brittle. They only move data one way, creating data silos and requiring constant maintenance.

Whalesync was built on a different principle: true, two-way sync. This creates a single, reliable source of truth between your most important tools. And while it's powerful enough for engineers, it was designed for operators. You can build a rock-solid data integration in minutes.

About Klaviyo and Notion

See how it works

Klaviyo

About

Klaviyo is the email and SMS marketing platform built for ecommerce brands. Whalesync two-way syncs Klaviyo profiles and lists with Airtable, Google Sheets, Notion, and more.

Show all

Klaviyo is where many ecommerce brands keep their customers: every subscriber is a profile with contact details, an address, and whatever custom properties the store sends along, grouped into lists and segments that drive email and SMS campaigns. With Whalesync, a Klaviyo account becomes three tables you can sync with Airtable, Notion, Google Sheets, or a database. Profiles sync both ways, custom properties and list membership included, so a row added in Airtable lands in the right Klaviyo list and an edit made in Klaviyo comes back to the sheet. Lists can be created, renamed, and deleted from the other side, while segments, consent, and Klaviyo’s predictive analytics come across read-only. Whalesync never sends a message to anyone and never deletes a profile.

Frequently asked questions

Yes! Whalesync offers true two-way sync. Unlike most apps that offer one-way syncs in two directions, Whalesync actually keeps your data in sync bi-directionally. Update data in one app and see it instantly to sync to the other (or vice-versa).

When a record syncs for the first time it becomes a record in sync. For example, if you sync 10 rows from Airtable to Webflow, you will have 10 records in sync. We do not "double-count" records across the two different apps.

Unlike other automation tools that count updates or tasks, Whalesync allows unlimited updates: those records can change as many times as you'd like.

A sync is a connection between two different apps (e.g. Salesforce & Airtable). When you turn sync on, Whalesync will continuously sync data between your apps.

A single sync includes as many data tables and field as you'd like.

You bet! We've simplified all the annoying parts of setting up a sync with Zapier. We support multi-reference fields, rich text, and images. For a full list, see our supported fields docs.

If data can't be synced (e.g. a required field is missing), Whalesync will alert you on the Issues page. This alert provides the exact error from your destination app and any other info that will help you fix the issue. In the meantime, Whalesync will continue to sync all data that doesn't have errors.

Absolutely! We love supporting organizations that are making the world a better place, so we're happy to offer a 20% discount to all nonprofits. To apply, just send us a note with proof of your nonprofit status (e.g. your 501(c)(3) determination letter) to support@whalesync.com and we'll get the discount applied to your account.
