Built around ecommerce data rather than newsletters, it ties order history to segments and automated flows, then reports revenue per campaign, which is the number that keeps merchants signed in. The free tier is real at 250 profiles and 500 emails a month, after which billing tracks list size from around 30 dollars. Its terms run on Massachusetts law, from a Delaware corporation based in Boston.

Why choose Omnisend over Klaviyo?
The decisive argument is data jurisdiction. Klaviyo is headquartered in the United States, which means personal data processed through it can be subject to non-EU legal regimes: the US CLOUD Act, FISA 702, or similar laws depending on the provider. After the 2020 Schrems II ruling, EU organisations must carry out a transfer impact assessment for every such data flow.
Omnisend removes that overhead. As a Lithuania-based provider, it operates under EU GDPR, and data stays inside the EU/EEA by default. For regulated sectors such as health, public administration, and finance, that's not a nice-to-have but a requirement. For everyone else, it's concentration-risk insurance: you avoid depending on a single jurisdiction that can change the rules without warning.
