Every campaign goes to one audience. You choose it at the Audience stage, after the draft is finished.

Pick one source

The audience picker offers four sources.

Saved lists

Lists you have built or imported, including Klaviyo segments and Mailchimp audiences.

Suggested segments

Segments LTV.ai proposes for this campaign, with customer counts.

CSV upload

Upload a list for this campaign. LTV.ai detects the columns automatically.

Exclusions

Applied on top of whichever source you chose.
You select one audience per campaign. LTV.ai does not merge several audiences into a single send, and it does not build per segment variants of one campaign. To reach two different groups with different messages, create two campaigns.

Empty and holdout lists

Lists with no members, and lists marked as holdout or exclusion lists, are hidden from the picker so they cannot be selected as a send target by mistake.

Counts

Every option shows a customer count before you commit. Counts reflect your synced data at that moment, so they move as Shopify and Klaviyo sync. The count shown is before exclusions. Your actual delivered volume will be lower once unsubscribes, bounces, and exclusions are applied. See Exclusions and suppression.

Sending limits

On a new domain, or when a campaign is much larger than your recent sends, LTV.ai caps or warns on volume before scheduling. See Warm-up and sending limits.
