For an email-marketing SaaS solution, Ligna has one of the most advanced CRM that has built-in voip phone. In fact Ligna's CRM is more advanced than some of the dedicate/pure CRM out there. I implemented Ligna on one of the business I consult, and their sales is getting higher and higher results. Review collected by and hosted on G2.com.
Ligna has so much awesome features that an user use. However, the administrator/whoever sets up Ligna for the team, will have to go through at least 10-20 hours of Ligna training to be so-so good at it. So there is a barrier to entry, however it is one of the best marketing solution out there, even better than GHL (especially when Ligna API & integration launches.)
