hey babe!

I'm Jessica Totillo Coster

Your Ecommerce + Email Marketing Strategist

Hey, I’m Jessica! An eCommerce and email marketing strategist for boutique owners and product entrepreneurs. I use data and experience to help you figure out the next best step in your business.


Because I’ve been exactly where you are. With 20+ years in the retail biz, owning my own multi 6-figure brick + mortar boutique, and as the only employee of a 7-figure eCommerce store. 

I started eCommerce Badassery when I realized how little information there was out there for scrappy entrepreneurs like you. I started helping people with their Klaviyo accounts, became known as the Klaviyo Ninja, and now I’m showing you step-by-step how to use the platform.

What It's Like to Learn From Me

word on the street

I can’t wait to learn from you!

What the FAQ?

Nope! You already have this content inside your membership hub!

Once you place your order you’ll receive an email invite to the eCommerce Badassery Vault where the course is stored. 

You’ll create your account to join + once you’re inside be sure to read the START HERE post pinned to the top of your home feed. This will walk you through how to navigate the platform and access your course content. 

All course content will be available immediately. 

Yes, actually you can! But if you don’t know what questions to ask or what features to research how do you know where to start?

At least that’s the feedback I hear MOST from clients and community members.

In this step-by-step course I walk you through the entire platform + show you all of the basic and advanced features while explaining how to use them

Yes and no. This course is mostly focused on the tech side of Klaviyo, though I do provide some strategy as I explain how to use specific features.

I am working on a full email marketing strategy course so stay tuned for that!

Due to the digital nature and low price of this product we do not offer a refund policy.

As a founding member you are getting the MVP of this program. 

Once the first round of students go through the course I will make updates based on their feedback which you will get automatic access to.


The Klaviyo Badassery course does not include access to me, but you are able to leave questions in the comments of each section if you need clarification on anything. 

I do encourage you to ask questions if you have them because it helps me identify where there may be gaps in the content and gives me insight into how I can improve the program. 

The Klaviyo Badassery Course does not include a private FB group or community but you will have access to the eCommerce Badassery Vault, our community on Mighty Networks. 

While the community is not an open forum like the FB group (yet) you will have access to other eCommerce entrepreneurs if you’re so inclined to connect with them.
