Using UGC in email and Klaviyo flows
Customer photos and video outperform studio creative in email because they read as real. Put cleared UGC across welcome, abandonment, post-purchase and win-back flows.
The brand's Klaviyo welcome flow ran three emails and zero customer photos. Drop one customer photo into each email and click-through jumped by a margin the email team had stopped expecting. The photo did not need to be perfect. It needed to be real.

Email is still one of the highest-return channels in ecommerce, and most of it is filled with brand-made creative. Swap some of that for customer content and the same flows tend to do more, because a customer photo reads as real where a studio banner reads as an ad.
Why does UGC lift email performance?
An inbox is a sceptical place. Polished brand creative announces itself as marketing. A real customer photo or video does not. It carries the same credibility it has on the product page, and it makes the email feel like a recommendation rather than a push. The mechanism is the same one that lifts the PDP, documented in how UGC lifts conversion: evidence beats assertion, and the email inherits that effect.
Where does UGC fit across the Klaviyo flows?
- Welcome flow: a wall of happy customers as first-impression proof the brand is trusted.
- Browse and cart abandonment: UGC of the exact product the shopper looked at, answering the doubt that stalled them.
- Post-purchase: customer content that reassures the new buyer and prompts them to create their own.
- Win-back: real customer results as a reason for a lapsed customer to look again.
| Flow | UGC to use | Job it does |
|---|---|---|
| Welcome | A grid of varied customer photos | First-impression proof the brand is real and used |
| Browse / cart abandonment | UGC of the exact product viewed | Answers the doubt that stalled the purchase |
| Post-purchase | How-they-use-it clips, a prompt to post | Reassures the new buyer; seeds fresh UGC |
| Win-back | Recent results from real customers | A concrete reason to look again |
Doing it well
- 1Use only cleared content: your licence must cover marketing use, not just on-site.
- 2Keep it relevant: the UGC should show the product the email is actually about.
- 3Keep images light: heavy email images hurt deliverability and load.
- 4Link it back: the customer content should lead to the product page, which carries more of the same.
The licence point is the one that trips brands up: content cleared for your website is not automatically cleared for email or ads, so scope rights per use the way the UGC rights and permissions guide sets out.

How to ask customers for reviews, and actually get them
Ask once the customer has used the product, make it one tap with media invited by name, follow up once: most under-collection is timing and friction, not refusal.

Post-purchase and thank-you-page UGC
The thank-you page does two jobs: it reassures a fresh buyer (cutting remorse and returns) and recruits the next wave of UGC while goodwill is at its peak.
