EU Data Sovereignty Matters

For EU-based SaaS companies, data sovereignty is not just a legal checkbox. It is a competitive advantage. EU enterprise customers increasingly prefer vendors that keep data within the EU. Being able to say "your data never leaves Europe" closes deals faster than explaining Standard Contractual Clauses.

Choose an email tool that supports this position. EU-headquartered tools like Brevo provide data residency by default. Tools like Customer.io offer EU data residency on enterprise plans. Even if you do not need EU residency today, choosing a tool that offers it gives you the option when an enterprise customer asks.

GDPR as Your Default Operating Mode

The best approach for EU-based SaaS is treating GDPR not as a constraint but as your standard operating procedure. Apply GDPR standards to all customers globally. Double opt-in for everyone. Consent tracking for everyone. Easy data deletion for everyone.

This approach simplifies your email operations (one set of rules instead of region-specific logic) and gives you a privacy-forward brand that resonates with customers everywhere. Privacy-conscious customers outside the EU will appreciate the same protections that GDPR requires.

European Email Deliverability

Email deliverability in European markets has nuances. Some European ISPs have different filtering patterns than US-based ones. Tools with strong European sending infrastructure and established relationships with EU mailbox providers tend to deliver better in European markets. Brevo and Mailjet, both EU-headquartered, have strong European deliverability. US-based tools work well in Europe too, but verify their deliverability performance in your target EU markets.
