"Sigstr has dramatically changed the way we are able to market to our most valued contacts - those we communicate with every day via one-to-one email. In the past, we relied on traditional marketing or referrals, and results were difficult to track - especially in the campaigns we attempted to do in our employee’s email signatures. With Sigstr, we can now track and measure the success of each campaign, it is a two minute process for me to update a campaign and apply it instantaneously to all employees across the globe."
