Win-Back Launcher

Before suppressing cold profiles, give them one last chance to re-engage. Win-Back Launcher enrolls disengaged contacts into a Klaviyo re-engagement flow, then automatically suppresses the ones that still don’t respond. Campaigns can run once or be automated on a recurring schedule — picking up only newly cold profiles each time.

How Win-Back works

The ListGuard Sunset Flow template

Don’t have a re-engagement flow yet? ListGuard provides a free pre-built ListGuard Sunset Flow you can import into Klaviyo in one click.

The template includes three emails:

The flow is already configured to trigger from the ListGuard Win-Back list — no flow setup needed once imported.

After importing:

1. Open the imported flow in Klaviyo
2. Review the email copy and customise your brand voice
3. Activate the flow, then come back to launch a campaign

Launching a campaign

Click ”+ New Campaign”

Opens the campaign launcher. You need at least one active suppression rule before you can launch.

Select a suppression rule

Choose a suppression rule to define your audience. The conditions for that rule are shown as a preview so you know exactly who will be targeted.

Select a Klaviyo flow

Choose the Klaviyo flow that will fire when profiles are added to the ListGuard Win-Back list. If no flows appear, use the import button to add the pre-built Sunset Flow template.

Set frequency

Option	Behaviour
Run once	Runs immediately — enrolls all profiles currently matching the rule
Automate	Runs on a recurring schedule — each run picks up only profiles that became cold since the last run

Configure automation (if automated)

Choose a schedule:

• Daily — runs at 9 AM UTC every day
• Weekly — runs at 9 AM UTC every Monday
• Monthly — runs at 9 AM UTC on the 1st of each month
• Custom — enter any standard 5-field cron expression (UTC)

Set the max profiles per run (batch limit, up to 2,000). This limits how many profiles are enrolled on each run to protect your sender reputation and Klaviyo rate limits.

Set wait period

Enter the number of days to wait before suppressing non-responders. After this many days, ListGuard re-evaluates the rule against enrolled profiles. Profiles that re-engaged will no longer match the rule and are left in your list. Profiles that still match are suppressed.

Recommended: 14 days — matches a typical 2–3 email re-engagement sequence.

Launch

Click Launch Campaign (or Start Automated Campaign if automating). The campaign appears immediately in your campaign list.

Managing campaigns

Each campaign row shows:

• Campaign name (Klaviyo flow name)
• Status badge — Pending, Running, Completed, or Cancelled
• Schedule badge (automated campaigns) — e.g. “Weekly”, “Monthly”
• Last run timestamp and launch date
• Profiles enrolled, re-engaged, and suppressed

Pausing and resuming

Automated campaigns can be paused at any time using the pause button on the campaign row. Paused campaigns stop scheduling new runs but retain all their enrollment history. Resume with the resume button — the schedule picks up from the next interval.

Deleting a campaign

Click the trash icon to permanently delete a campaign. This also cancels any pending scheduled runs. Previously enrolled profiles are not affected.

Enrollee deduplication

ListGuard tracks every profile enrolled in each campaign. On each automated run, profiles that were enrolled in any previous run of the same campaign are automatically excluded — they will never be re-added to the win-back list regardless of their current tier. This prevents duplicate flows and protects your sender reputation.
