The Mailshake software is a software for involvement and commercial automation. The startup was founded in 2015 by Colin Mathews, Sujan Patel, and Bob Senoff. The software enjoys significant notoriety due to an in-depth course on email prospecting.

Originally, this tool was strictly a prospecting by email system. Now, it has become a complete commercial automation system that integrates connections with CRM systems along with additional marketing solutions like social platforms.

Among its key functions are automating outreach efforts, monitoring potential client activity, handling and managing phone communications, as well as multi-platform exchanges.

Yesware identifies itself a solution designed to help sales forces conduct cold mailing campaigns on a grand scale. Yesware was established in 2010 under the guidance of Matthew Bellows, Rajat Bhargava, and Cashman Andrus.

It is a prospecting tool that is highly widespread in the US. Yesware enables the launch of multichannel campaigns (emails, phone calls, LinkedIn…) with integrations with Microsoft, with Google, with Salesforce. Because of the extent of these integrations, the cost may appear significant for a user who doesn't need all these features.
