Customer.io is great for two kinds of uses: 1. Companies that are looking to get started with marketing automation and appreciate a lightweight UI (i.e. not your typical enterprise software) and 2. Companies that are looking for some more advanced functionality that requires flexibility and customization, and are willing to devote the developer resources to implement it. We happen to fall into the second category, which is why we chose Customer.io for our marketing automation needs at Woopra.
A lead magnet (a.k.a. an optin bribe) is something amazing that you give away for free in exchange for an email address. This doesn’t have to cost you anything to create; most lead magnets are digital materials like PDFs, MP3 audio files, or videos that you can create yourself at minimal or no cost. It can be absolutely anything you want, so long as it provides value to your visitors for free.
