Case studies
Most brands come to me in one of three situations.
Ready to scale
Niche fragrance DTC · EU
A big, engaged list and a brand ready for more.
I built the Shopify store, the Klaviyo flows and a weekly campaign calendar, then launched Meta ads from zero.

An idea to make real
Personal care
A product with no sales, no reviews and six markets to launch.
I designed the packaging, built the Amazon listings market by market, and ran the ads and creators to start the reviews.

Channels that didn't talk to each other, and no single owner.
They needed one owner for the store, email, ads, product and customer support. I've led all of it since 2023, with every channel working toward the same numbers.

About
Over ten years from the warehouse floor to the storefront.
Sarai Da Silva is a Madrid-based e-commerce consultant who helps DTC brands scale through Shopify, Klaviyo email marketing and product development.
I started in design and brand, then moved into operations and product management. That path taught me how a store actually runs: the inventory, the supplier calls, the returns and the numbers behind them.
Today I connect all of it. The store, the email program and the product decisions are planned together, so every campaign feeds the next one.

FAQ
Questions I get a lot.
What does an e-commerce consultant do for a DTC brand?
I take ownership of the parts of your online business that drive revenue: the Shopify store, email and CRM, paid social and product launches. For some brands that's a single project, like a new store or a Klaviyo rebuild. For others I work as a fractional Head of E-commerce on an ongoing basis.
Do you work with brands outside Spain?
Yes. I'm based in Madrid and work remotely with brands in the US, the EU and LATAM. One of my longest clients is a US pet brand I've worked with since 2023.
Can you manage our Klaviyo account every month?
Yes. I build and run flows, campaign calendars and segmentation on a monthly retainer. For a niche fragrance brand, that program generated $1.2M+ in Klaviyo-attributed revenue in under a year.
Do you help with product development and packaging?
Yes. I've developed and launched products since 2014, from 18 snack products in Venezuela to packaging and Amazon launch creative for a personal care brand selling in six EU markets.
Do you work in Spanish?
Yes, I work natively in English and Spanish.
