promeli.ia automates promotions for Mercado Livre sellers in Brazil without selling below margin.
Every hour it reads the campaigns Mercado Livre offers for each listing (daily deals, lightning deals, fee-reduction campaigns, seller discounts), runs the margin math with that listing's own cost, fee, shipping and tax, and joins the best campaign that keeps the seller's minimum margin. It switches when a better campaign appears and leaves when one stops paying off.
Fee reductions (rebates) are counted the way Mercado Livre applies them. After every change it checks the price Mercado Livre actually applied, and exits immediately if the margin is broken.
Sellers can approve each change with one click or turn on the automatic agent. It connects through Mercado Livre's official API. 7-day free trial, no credit card.
