Connect Klaviyo to Appalix
Klaviyo is the leading email and SMS platform for e-commerce. Connecting it to Appalix means every contact you add to Sage CRM is automatically added to your Klaviyo list — triggering your welcome flows, win-back sequences, and campaigns without any manual export. Setup takes under 3 minutes.
What you'll need
- An Appalix account on Pro plan or above
- A Klaviyo account (any plan)
- A Klaviyo Private API Key and the target List ID
Step 1 — Create a Klaviyo Private API Key
- Log in to Klaviyo and click your account name (bottom-left).
- Go to Settings → API Keys.
- Click Create Private API Key.
- Give the key a name (e.g. "Appalix Sync") and grant the following access:
- Lists — Read/Write
- Profiles — Read/Write
- Click Create and copy the key — it starts with
pk_.
Step 2 — Find your Klaviyo List ID
- In Klaviyo, go to Lists & Segments in the left sidebar.
- Click the list you want to sync contacts into.
- Click Settings (gear icon) at the top of the list view.
- Copy the List ID — it's a short alphanumeric code like
Xk7abc.
Step 3 — Connect in Sage → Integrations
- In Appalix, navigate to Sage → Integrations in the left sidebar.
- Scroll to the Email Marketing section and find the Klaviyo card.
- Click Connect and fill in:
- Private API Key — the key from Step 1
- List ID — the ID from Step 2
- Click Save & Connect. The card shows a green Connected badge.
What the integration does
- Contact sync — contacts created or updated in Sage are added to your specified Klaviyo list as profiles.
- Flow triggers — adding a profile to a list automatically triggers any Klaviyo flows subscribed to that list (welcome series, nurture sequences, etc.).
Frequently asked questions
Can I sync to multiple Klaviyo lists?
One list per workspace is supported. Update the List ID in Sage → Integrations → Klaviyo to change which list contacts sync to.
Will existing Klaviyo profiles be updated?
Yes. Klaviyo uses email as the unique identifier. If a profile with the same email already exists, it is updated with any new fields rather than creating a duplicate.
Are my API credentials stored securely?
Yes. Your Private API Key is stored encrypted in your workspace database and never exposed in plain text after saving.
