Why Waitlist Signups Are Not Guaranteed Sales

Signups express interest, not commitment

A waitlist signup costs a customer nothing and commits them to nothing. Some will buy the moment the product returns; some will have changed their mind, found an alternative, or simply forget. That is why honest demand tooling never converts signups into expected revenue with an invented conversion percentage, and never presents a numeric score as a purchase probability. What signups do give you is ranking and shape: which product, which variant, how recently, and how many people cared enough to leave an email and confirm it. Use that to prioritize reorders and sizes - and let actual sales, once they happen, teach you your real conversion rate.

Shelfetti provides waitlist demand signals and consent-based notifications. Signups are expressions of interest, not guaranteed sales.
