When & why to run ActiveCampaign with Klaviyo
Automation + CRM vs. ecommerce email & SMS.
ActiveCampaign is a broad marketing-automation platform with a built-in CRM for any industry; Klaviyo is specialized for ecommerce, with deep store data and native SMS. Choose ActiveCampaign for cross-industry automation and sales features; choose Klaviyo if you're an online store optimizing email and SMS around purchase behavior.
Automation Blueprints — make them work together
The real payoff is the stack. These are concrete ActiveCampaign ↔ Klaviyo workflows worth building.
New contact → sync profile
New Contact
During migration or dual-run
Add Profile
Run both or migrate without losing contacts.
Purchase → update CRM
Placed Order
Known contact
Update Contact / Deal
Feed ecommerce purchase data into ActiveCampaign's CRM.
Setup steps
The Zapier/Make path, start to finish.
- 1
Create a Zapier or Make account and connect both ActiveCampaign and Klaviyo (authorize each via OAuth).
- 2
Create a new Zap/Scenario with the trigger — ActiveCampaign: New Contact.
- 3
Add a filter for the condition (During migration or dual-run) so the workflow only fires when it should.
- 4
Add the action in Klaviyo (Add Profile) and map the fields from the trigger data.
- 5
Test with a live record, verify the result, then turn the automation on and repeat for the other workflows.
Edge cases & rate limits
What breaks in production — plan for these before you scale.
- Field mapping: ActiveCampaign and Klaviyo fields rarely map 1:1 — normalize dates, currencies, and dropdown/picklist values explicitly.
- Pick a source of truth per field to avoid two-way syncs overwriting each other in a loop.
- ActiveCampaign: Key capabilities (unlimited actions, advanced segmentation, A/B testing, attribution, SSO) are gated behind Plus/Pro/Enterprise.
- ActiveCampaign: Email sends are capped at a multiple of contacts, and the lowest prices require an annual commitment.
- Klaviyo: Pricing scales steeply with active profiles — cost grows automatically as your list expands, with no flat rate.
- Klaviyo: SMS/MMS credits are billed separately on top of the profile price and can dwarf the base cost for heavy senders.
- Zapier/Make task usage is metered — high-volume workflows can burn through your monthly task/operations quota, so batch where possible.
- Watch API rate limits on bulk backfills — throttle or batch to stay under each tool's per-second/per-minute caps.
