EmailOctopus

EmailOctopus is a London-based email-marketing company founded in 2014 by Jonathan Bull. It is bootstrapped and founder-owned, with no venture funding, and is known for undercutting incumbents on price by building its sending layer on commodity infrastructure (Amazon SES).

The platform offers campaigns, drip automations, signup forms, and landing pages aimed at creators, non-profits, and small businesses. As a UK private company with no external investors, it sits cleanly within the European-alternatives scope, though its US-cloud sending layer is a sovereignty caveat relative to fully EU-hosted peers.
