This market is plagued with promises, Mailshake simply delivers better than anyone, I too think the price point is respectful but not only for the app, it's value also comes from their content which is both timely and extremely well written - hat's off!
I used Mailshake for years before joining the team to help it grow. Coming from a sales background I used many tools to cold email. Mailshake is the most simple tool and extremely effective from a Gsuite email.
In addition to closing dozens of eCommerce consulting deals, I was able to get free accommodation in Bali by emailing resorts and offering to exchange drone footage. Very versatile tool because you can simply add in more mail accounts.
I thought I knew a lot about cold email and sales process and learned even more than I expected with this eBook.
