Your role as Customer Success Manager (CRM)

The Customer Success Manager (CRM) will manage a portfolio of clients while taking hands-on responsibility for the execution, optimisation and delivery of CRM activity across email, SMS and customer lifecycle programmes. You will be the primary day-to-day client contact, lead regular meetings, manage CRM plans and ensure agreed work is delivered accurately, on time and in line with each client’s commercial objectives.

This is not solely an account management or advisory role. You will work directly within platforms such as Klaviyo, Dotdigital and Braze to build, test, schedule, launch and optimise campaigns and automated journeys. You will combine strong client relationship skills with practical platform expertise, taking work from brief through to execution, reporting and continuous improvement.
