Most of the funnels that are ready to use come prebuilt with promotions for various targeted offers - highly congruent with the reason they signed up on your list.
However, there are also funnels created purely for:
Engagement (ie. follow you on social, share content with friends etc), or
Branding (i.e. getting your product and services in front of people to build a recognisable and memorable company)
Product research and development, onboarding your customers, automating delivery of content and a whole lot more.
Every business needs multiple email funnels, for multiple purposes, FunnelMates makes that a whole lot easier.
