QA flow copy and setup inside Klaviyo to ensure technical accuracy.
Performance & Reporting
Monitor campaign and flow performance metrics open rates, click rates, revenue, deliverability.

Ensure all deliverables meet quality standards and are submitted on time, every time.
WHAT WE'RE LOOKING FOR;

How You Work
Client-first mindset: you treat every account like it's your most important one.
You take ownership. If something slips, you catch it, own it, and fix it.
Clear, confident communicator in writing, on calls, and across internal teams.
Organised and structured you use systems to stay on top of complexity.
Proactive, not reactive you anticipate problems before they reach the client.
Strong delegation skills: you know how to brief, follow up, and hold the team accountable.
WHY MACH 33
You won't be micromanaged or stuck in a bureaucratic loop. You'll have real ownership over your accounts, work with a sharp team that cares about results, and contribute directly to client growth. If you're someone who takes pride in execution and wants to be measured on outcomes not just output this is the right place.
Ready to apply? We'd love to hear from you.
