About Campaign KPI
Your email campaign is up and running.Now you are curious: Will it be a blast? Ar a failure? Campaign KPI for Klaviyo brings the results of your Klaviyo campaigns straight to wherever you are: your iPhone. Opens, clicks, click-to-open, unsubscribes and revenue — the moment the first figures come in. No need to boot up a laptop or scroll through a dashboard. WHY YOU NEED IT One of the best times to send emails is on Sunday mornings. That’s exactly when you don’t want to be stuck at your desk. With this app, a quick glance at your phone is all it takes — over a coffee, on the train, or between appointments. THE FEATURES • Your latest campaign in real time, with all key metrics at a glance • Swipe through recent campaigns and spot patterns rather than individual figures • Trend analysis: the most important KPIs over time • A/B test results for your latest campaign • Multiple Klaviyo accounts simultaneously — for agencies and businesses with multiple shops • Projections of campaign results just a few hours after send-out • Coming soon: filtering by tags THE PROJECTIONS On election night, a projection appears on the screen at 6 pm, and in the end it turns out to be astonishingly close to the actual result. You can have exactly the same for your campaigns. Just a few hours after sending, the app projects where your campaign will end up: open rate, click-through rate, click-to-open rate and revenue. You’ll also get a range rather than a pseudo-precise figure — and an indication of how stable the forecast currently is. The forecast learns from your own past campaigns, not from industry averages that have nothing to do with your mailing list. How accurate it is depends on your data set: it’s most reliable for larger mailing lists and for campaigns that remain comparable over time. YOUR DATA The app is read-only. It does not send any emails, create any campaigns or flows, nor does it make any changes to your Klaviyo account. It does not retrieve any profile or recipient data from your customers in the first place. Processing and temporary storage take place in a data centre in Germany. You can revoke access to your Klaviyo account at any time — access will then cease immediately. WHO’S BEHIND IT Built by people with over 25 years’ experience in email marketing. The brains behind Campaign KPI is the only Klaviyo Champion in the DACH region. Through his company, Meister Lampe und Freunde GmbH, he is a Klaviyo Platinum Partner and a member of the Klaviyo Partner Advisory Council. The idea for the app came about one Sunday morning — when the founder once again had to boot up his laptop to check how a campaign was performing. PREREQUISITES You need an existing Klaviyo account. You set up the connection within the app. NOTE Campaign KPI for Klaviyo is a standalone product by Uwe-Michael Sinn, Managing Director of Meister Lampe. Klaviyo is a trademark of Klaviyo, Inc.
