We are looking for an Email Marketing Growth Manager to help grow our reverse lookup products through structured experimentation in email marketing.
This role is focused on one core objective: maximizing the business impact of email as a growth channel.
You will be responsible for designing, prioritizing, and analyzing A/B tests across the email funnel — from pre-purchase conversion to post-purchase activation and retention. You will work closely with the Email Team and Growth Team to turn insights into experiments that improve performance.
This role is ideal for someone who understands how to use testing, messaging, user behavior analysis, and market research to increase conversion volume and improve retention.
If you have a strong CRO foundation and want to apply experimentation to email growth, retention, and lifecycle optimization, we’d love to hear from you.
