EmailOctopus is the low-cost email-marketing service operated by Three Hearts Digital Ltd at 86-90 Paul Street, London EC2A 4NE, United Kingdom. The product targets indie creators, bloggers, small SMBs, and price-sensitive marketers who want a Mailchimp / MailerLite / ConvertKit alternative with a particularly generous free tier (free up to a meaningful subscriber count) and competitive paid pricing, for example approximately $480/year at 100,000 subscribers. The brand is well-known in the indie-hacker and content-creator community.
For an EU-sovereignty audit the listing has structural caveats. The operating entity is UK-incorporated post-Brexit (UK adequacy decision under Art. 45 GDPR keeps transfers EU↔UK legally clean), but EmailOctopus historically built its product as a thin layer on top of Amazon Simple Email Service (Amazon SES) for the actual mail delivery, a US-owned hyperscaler dependency for the core product workload. No public ISO 27001 / SOC 2 certifications, no named sub-processors page, and the hosting region for application data is not publicly disclosed. The brand is GDPR-compliant per the homepage, but procurement-grade buyers needing detailed transfer documentation should request the DPA directly.
Pricing in EUR / USD: free tier with no credit card required; paid tiers scale by subscriber count with monthly or annual billing (10% discount for annual). Best fit: indie creators, low-volume bloggers, small SMBs, and price-sensitive marketers who want a serviceable Mailchimp alternative and accept the UK + Amazon SES dependency. Procurement-grade EU buyers should choose CleverReach (DE) or rapidmail (DE) at SMB tier, or Maileon / Inxmail at enterprise.
