Retargeting Participants: How to Convert Sweepstakes Entrants into Customers

Running a sweepstakes can build your email list and grow your social following quickly, but what happens next?
Many brands leave value on the table by failing to retarget participants.

Turning sweepstakes entrants into customers requires a clear post-campaign strategy.
Here’s how to do it effectively.
Collect the Right Data Upfront
During your sweepstakes, gather:
-
Email addresses (with opt-in for marketing)
-
Social handles for retargeting ads
-
Interest tags (via survey questions like “Which product are you most excited about?”)
This segmentation lets you send relevant follow-up messages instead of generic blasts.
Send a Warm Thank You Email
Immediately after the campaign ends:
-
Thank participants for joining.
-
Announce when winners will be contacted.
-
Offer a small incentive (e.g., 10% off) to non-winners to encourage their first purchase.
This maintains the momentum while your brand is still top-of-mind.
Use Retargeting Ads on Social Media
Upload your entrant list to platforms like:
-
Facebook Ads Manager
-
Instagram Ads
Run ads highlighting:
-
Products featured in your giveaway.
-
Customer testimonials.
-
Special limited-time offers.
This keeps your brand in front of warm leads who are already familiar with your products.
Create a Welcome Series
Set up a post-sweepstakes email flow:
-
Email 1: Thank you + exclusive offer
-
Email 2: Product benefits or customer stories
-
Email 3: Reminder about your exclusive offer
Tools like Klaviyo and Mailchimp help automate this series for consistency.
Track Conversions and Adjust
Monitor:
-
Click-through rates
-
Conversion rates from emails and retargeting ads
-
Which product pages entrants visit most
Use this data to refine your future campaigns and tailor offers.
Why Retargeting Matters?
Without follow-up, sweepstakes become a one-time engagement with minimal long-term benefit. Retargeting entrants:
-
Converts them into paying customers
-
Increases ROI on your sweepstakes spend
-
Builds stronger customer relationships over time
