Step-by-step guide to sending a multi-list campaign in Klaviyo
Step 1: Selecting lists or segments
- Log in to Klaviyo and go to Campaigns.
- Click Create Campaign.
- Give it a name and choose the sending channel (email, SMS, etc.).
- In the "Send to" section, select the target lists and segments.
Key advantage: Klaviyo automatically deduplicates contacts to prevent multiple sends.

Step 3: Understanding the recipient count calculation

- Automatic duplicate elimination.
- Exclusion of unsubscribed or deleted contacts.
- Filtering of unengaged profiles to preserve sending reputation.
The estimated final number of sends may vary slightly due to Klaviyo's automatic exclusions.
Step 4: Campaign scheduling and sending
- Check your content (subject, text, CTA, images).
- Choose immediate or scheduled sending.
- Activate Smart Sending to avoid over-solicitation.
- Track performance via the Klaviyo dashboard.
