Frequently Asked Questions
Does Spark Mail store my emails on its servers?
Yes — Spark syncs emails through Readdle's servers for push notifications, AI features, and team sharing. Your emails transit US infrastructure even if your email provider is EU-based. This creates a GDPR conflict for business use.
What is the best European email client for privacy?
Thunderbird (open-source, processes email locally) is the gold standard for desktop. On mobile, FairEmail (Netherlands) on Android is open-source and privacy-first. K-9 Mail (now merged with Thunderbird) is also excellent.
