Transpromo is a compound expression formed from the words "transaction" and "promotional". By adding relevant messages, companies can piggyback promotion or even advertising onto existing transaction-related documents, such as statements, invoices, or bills. Transpromotional documents combine CRM (customer relationship management) and data mining technology with variable data printing and location intelligence.

Using the real-estate on electronic documents and bills for marketing and promotional offers, results in a higher click rate and ROI than traditional email marketing has offered. Email content can be customized to include relevant, targeted and personalized marketing offers.
