Propsect.io does one very specific part of marketing automation (finding cold leads and engaging them to become warm), but it does it very well. One particularly good feature about Prospect.io that’s not easy to find elsewhere is that the automation emails can be triggered directly from your mail server (e.g. G Suite or Microsoft Exchange) so your emails appear identical to if you had sent them manually.
However, the term “marketing automation” has become a buzz-word, where marketers seek out marketing automation software under the impression that all of the digital marketing tools necessary for growth, including those needed to generate new leads, roll up under the hood of marketing automation. This misconception leaves many marketers with sophisticated tools to automate the middle of their funnel, but no solution to generating new leads to nurture in the first place.
