Here's their top case studies: Arc, Parabola

And testimonials from clients:

“Getting things done more efficiently is a big part of what 8base is about. We understand the importance of fostering core capabilities without getting sidetracked a million times a day. Handling cold email outbound and deliverability in-house would mean just that – it would have been a frustrating, roundabout way to achieve a goal. So, for our own peace of mind, we wanted someone as capable and savvy as Senders to take care of that for us.”

- Karel Montes, Operations Manager

“If anyone understands the power of smart automation, that’s our team. After all, we built Parabola to help other organizations streamline their most time-consuming, tedious processes. We knew that cold email would be a strong addition to our outreach efforts and it could help us reach more people – if done right. So instead of putting it on all our plates, we found Senders. Their strategy team supported us in the early days of our collaboration, while their deliverability and infrastructure continue to serve as the base of our email outreach, making sure it’s as safe as it is effective.”‍

- Andrew Udell, Head of Operations
