Comparison
AmbassadorFlow vs Stamped.io (2026)
Last updated: June 30, 2026
A full comparison of pricing, features, and touchpoints, to help Shopify and WooCommerce brands pick the right referral platform.
The 30-second answer
The best Stamped.io alternative for Shopify and WooCommerce brands is AmbassadorFlow. You pay only when referrals bring in new revenue (no fixed fee to start), with 6 activation touchpoints, SMS, multi-currency, and built-in fraud detection. Choose Stamped.io instead if its strengths below fit your store better.
Our verdict
Stamped.io is primarily a loyalty platform where referrals are a secondary feature. If your main goal is driving new customer acquisition through word-of-mouth, you'll find the referral tools limited. AmbassadorFlow is built from the ground up as a referral and ambassador engine, activating at checkout, email, SMS, and packaging inserts, with performance pricing so you only pay when it works. On activation specifically, Stamped.io has no checkout activation or SMS or packaging inserts, where AmbassadorFlow runs all of them.

When AmbassadorFlow is the better choice
- You run a Shopify or WooCommerce store and want one tool that works on both.
- You would rather pay only when referrals drive new revenue than commit to a fixed monthly fee.
- You want customers activated across 6 touchpoints (popup, post-purchase, packaging, email, SMS), not just a share link.
- You need multi-language, multi-currency, and built-in fraud detection out of the box.
When to choose Stamped.io instead
Choose Stamped.io if your primary need is a reviews and UGC platform for Shopify and you want referral features without adding another vendor. Stamped's reviews product is solid with good Shopify integration. If reviews and social proof are your top priority and referrals are a nice-to-have, Stamped can consolidate both under one platform. Note that the Loyalty module (which includes referrals) is $299/mo, making Stamped a significant investment. For brands where referral-driven new customer acquisition is a priority, a dedicated referral tool like AmbassadorFlow will deliver more referral revenue through multi-touchpoint activation and performance pricing.

Frequently asked questions
Can I use AmbassadorFlow alongside Stamped.io Reviews?
Yes. This is a common combination. Stamped.io handles reviews and UGC (which it does well), while AmbassadorFlow handles referral activation across checkout, email, SMS, and packaging inserts. You get best-in-class tools for both reviews and referrals without compromise.
How much does Stamped.io's referral feature cost?
Stamped.io's referral features are part of its Loyalty product, which is priced separately from the Reviews product. Pricing depends on the tier you choose, and getting both reviews and loyalty/referrals costs more than reviews alone. For a dedicated referral solution, AmbassadorFlow's performance plan costs $0/mo, so you only pay when it generates sales.
Is AmbassadorFlow cheaper than Stamped.io?
For most ecommerce brands, yes. Stamped.io starts at $199/mo as a fixed cost. AmbassadorFlow's Performance plan is $0/mo, where you pay 10% only on the extra sales it generates, with fixed Grow ($99/mo, 3%) and Scale ($199/mo, 1%) plans if you prefer a flat fee.
What can AmbassadorFlow do that Stamped.io can't?
AmbassadorFlow activates referrals at checkout, email, SMS, and physical packaging inserts. Stamped.io has no checkout activation or SMS or packaging inserts, so it reaches customers on fewer channels.
How long does it take to switch from Stamped.io to AmbassadorFlow?
