Avantario

Avantario* is a Klaviyo Platinum Partner helping premium ecommerce brands convert first-time buyers and turn them into loyal, high-value customers.

Since 2019, we have worked with more than 500 ecommerce brands and helped generate over $100 million in Klaviyo-attributed revenue.

and more.

Our work goes far beyond sending newsletters. We build and operate complete retention systems across email, SMS, WhatsApp, push, and print - combining lifecycle strategy, campaign planning, copywriting, design, segmentation, automation, deliverability, integrations, experimentation, and performance analysis.

As a Klaviyo Platinum Partner, Avantario ranks among the top 2% of Klaviyo partners worldwide.

Brands can work with us in the way that best fits their team:

• Done-for-you: We manage your retention marketing end-to-end.
• Done-with-you: We build and optimize your Klaviyo setup together with your team through 1:1 workshops.
• Do-it-yourself: We offer courses and consulting where you'll get access to proven systems, templates, and ecommerce experts inside our retention marketing community.

Whether you are building your retention foundation or scaling an established ecommerce operation, we identify the biggest opportunities in your customer journey and help you turn them into sustainable, profitable growth.

Headquartered in Zug, Switzerland, Avantario works internationally, with team members in the US, UK, Germany, and Switzerland. We support clients in English and German.
