Omnisend

Omnisend is the email and SMS marketing platform built for e-commerce brands, founded in Vilnius, Lithuania in 2014 by Rytis Lauris and Justas Kvedaras. While Mailchimp and Klaviyo serve broad markets, Omnisend went deep on one niche: Shopify and WooCommerce stores that need pre-built automations tuned to the e-commerce lifecycle — abandoned cart recovery, browse abandonment, post-purchase follow-ups, and win-back sequences. The company bootstrapped to $20M+ ARR. Omnisend's e-commerce-specific templates and native Shopify integration (one-click install, automatic sync of product catalog and customer purchase history) made onboarding dramatically faster than general-purpose email tools. The platform added SMS as a second channel with the same automation builder, so a single abandoned cart flow could send an email at hour 1, an SMS at hour 4, and another email at day 3 — coordinated across channels from one interface. E-commerce-specific segmentation (purchased X product, spent over $Y, browsed category Z) enabled highly targeted campaigns without custom development.
