Expressly developed new technology to dramatically improve effectiveness of online customer acquisition campaigns across merchants, both inbound and outbound. When new users click a banner, email or SMS acquisition campaign, Expressly transfers registration data obtained from the source merchant, after asking the user's consent; this leads to a 10-fold increase in campaign effectiveness and improves the customer journey. Shop's inbound campaigns with Expressly can benefit from dramatically lower CPA; while outbound campaigns can be much better monetised when using Expressly.
