Sarbacane

Sarbacane has served European businesses for over 20 years and built its platform with compliance first, meaning GDPR and other privacy rules are already baked in. The automation engine handles conditional workflows where emails trigger based on customer behavior, and you can layer in SMS campaigns that follow the same logic. Segmentation tools let you divide your list by purchase history, engagement level, or custom attributes.

Best for agencies serving French, Spanish, or Benelux markets where data privacy isn't an afterthought but a business requirement. If your clients worry about compliance violations, this platform removes that anxiety. The workflow automation is straightforward enough for non-technical users to build moderately complex campaigns without needing a developer, which matters when you're scaling your team and teaching clients to manage their own flows.
