This is what you get back
Upload your Mantle export and the checker returns a real import preview — program settings, affiliates, referral history and payouts, each counted and validated, with anything that needs a second look flagged before it lands in affilut.
Sample data — your preview is built from your own Mantle export.
Preview my Mantle export — no account needed →What comes across
The checker reads your Mantle export the way affilut will import it, and shows the count for each part of your program so there are no surprises on the other side.
Affiliates & partners
Every affiliate comes across with their email, name and status — de-duplicated on email, the identity affilut keys on.
Referral codes
Each partner's referral/coupon code maps straight to an affilut affiliate, so existing links keep attributing.
Referral history
Tracked referrals and conversions import against the right affiliate, with amounts and commission preserved.
Recorded payouts
Past payouts come across as history so your books stay continuous — affilut never holds funds, you pay direct.
Your program moved in three steps
Export from Mantle

Start your affilut program and bring your affiliates across — before Mantle deletes the originals. Flat fee, 0% of revenue, pay affiliates direct.
Frequently asked questions
What is happening to Mantle, and when?
HeyMantle is winding down on 14 August 2026. Shopify app developers who ran an affiliate or partner program on Mantle lose the tool — and the affiliate data is scheduled for deletion. If you don't export and re-home your affiliates, codes and referral history before the 14 August 2026 cutoff, that program history is gone.
What does this checker do?
Export your affiliate program from Mantle and upload the files (CSV, or a JSON dump). The checker reads them in memory for that one request and shows exactly what will import into affilut — how many affiliates, referral codes, tracked referrals and recorded payouts import cleanly, and which rows need a second look. Free, instant, and nothing is stored.
Does this move my affiliates into affilut automatically?
No. This checker previews exactly what will import — it doesn't write anything into affilut. To make the move you start an affilut program and bring your affiliates and their codes across: a guided, manual step today, not a one-click import. The preview is your checklist for what to recreate before Mantle's 14 August 2026 deletion.
Why affilut?
affilut is Stripe-native affiliate tracking built for exactly this buyer: a flat monthly fee, 0% of your revenue, and you pay affiliates directly rather than routing money through the tool. Your Mantle affiliates and their codes map straight across, so you can rebuild your program in affilut and keep every affiliate relationship you built.
Is anything stored?
No. The preview runs in-memory for that one request and nothing is written to a database. There's no account and no login — upload, read your preview, done. Leave an email only if you want a copy.
A better home than the tool you're leaving
affilut tracks affiliate conversions for Stripe-based businesses — including Shopify app developers billing through Stripe. It connects to Stripe read-only and attributes referred sales from charge metadata, so there's no pixel and no SDK to maintain.
The commercial model is the point: a flat monthly fee gated only on tracked revenue, 0% of your sales or payouts, and you pay affiliates directly. Bring your Mantle program across and keep every affiliate relationship you built.
