# Klaviyo Audit & Advisory Call with Josh Rauer

> The call can be held in English or German, whichever you prefer. In this call we go through your Klaviyo account together and figure out where your biggest revenue potential is. After booking, you'll give me access to your Klaviyo account. That way I can review your flows and campaigns ahead of our call and come prepared with concrete recommendations. During the call we walk through my analysis, so you leave knowing exactly what to tackle next. The rest of the time is yours for any questions, whether it's segmentation, deliverability or anything else.
