Smile.io vs Yotpo Loyalty — 90 days of data from 8 Shopify stores

8 Shopify stores, 90 days, both platforms tested. Redemption rates, repeat-purchase lift, and the uncomfortable finding: under $50K MRR neither moved the needle.

Eight Shopify stores agreed to a 90-day loyalty-app A/B in early 2026. Four ran Smile.io, four ran Yotpo Loyalty. Different verticals, different sizes, same instrumentation. Here's what came out.

The 8 stores

Three apparel brands ($30K to $180K MRR), two beauty DTC ($45K to $90K MRR), two supplements ($60K to $140K MRR), one home decor brand ($25K MRR). All on Shopify, all on Klaviyo or Mailchimp for email, none using subscription as a primary revenue stream.

Stores were paired by MRR and category, then randomly assigned. Same point structure on both: 1 point per dollar spent, 100 points = $5 reward. Sign-up bonus 200 points. Birthday bonus 200 points. We held the program design constant.

Setup time

Smile.io was faster to live. 35 to 50 minutes per store, including theme integration and a first email. Yotpo took 80 to 120 minutes per store, mostly because we connected the SMS layer at the same time, which is the actual reason a store would pick Yotpo.

If you don't care about SMS, Yotpo's setup overhead is probably wasted on you.

The 90-day numbers

Average redemption rate across all 8 stores: 4.6%. Smile stores: 4.8% average, 3.1% to 7.0% range. Yotpo stores: 4.4% average, 3.4% to 6.5% range. Within noise.

Repeat-purchase lift, measuring 90-day repeat rate vs the 90 days before launch: Smile stores averaged 11.2% lift, Yotpo stores averaged 10.3% lift. Also basically identical.

AOV impact was small on both, 2 to 4% on enrolled customers vs control. Not nothing, not what marketing pages claim either.

Where Yotpo actually pulled ahead

On the two stores that fully wired Yotpo SMS into the loyalty triggers (back-in-stock for loyalty members, VIP early access, points-balance reminders), SMS-attributed revenue landed around $7,400 and $11,200 over the test window. That is a real lift but it is the SMS doing the work, not the loyalty engine. Smile plus a separate SMS tool would have delivered similar.

Where Smile actually pulled ahead

Time-to-first-redemption was meaningfully faster on Smile. Median 19 days vs 31 days on Yotpo. The on-site widget and email cadence default to nudging redemption harder. For owner-operators who want signs of life fast, this matters psychologically more than statistically.

The uncomfortable finding

On the 3 stores under $50K MRR (the home decor and two of the apparel brands), neither platform moved the repeat-purchase needle in a defensible way. Lift was 4 to 7%, well inside the variance we saw in pre-launch monthly cohorts.

Loyalty programs need volume of returning customers to compound. Under roughly $50K MRR, most of these stores are still in acquisition mode. The right tool there is paid social and email frequency, not points.

Above $80K MRR every store in the test got real, measurable lift. Below $50K, neither platform paid for itself in the test window. Between $50K and $80K, mixed.

What we'd actually pick

Under $50K MRR: skip both for now. Use Shopify's native discount codes and a basic email flow. Revisit at $80K.

$50K to $200K MRR, no SMS strategy: Smile.io. Faster to live, simpler dashboard, $49 to $199 plan range covers it.

$50K MRR plus, with SMS as a real channel: Yotpo. The integrated loyalty plus SMS plus reviews stack is genuinely tighter than running three separate apps. $79 to $349 range.

$200K MRR plus, custom rules required: LoyaltyLion. We didn't test it here but every store at that scale we work with has eventually moved to it.

What we billed

$850 per store flat for setup, integration, copy, and 30 days of post-launch tuning. Owners liked having a number to pencil in.
