Why switch

What Spore changes versus Mailgun

The real differentiator isn't one more feature: it's jurisdiction. With Mailgun, your recipient data flows through a US entity, exposed to the CLOUD Act even with EU hosting. Spore aligns hosting, legal entity and support in Europe — GDPR is the default behaviour, not a checkbox.

Let's be honest: Mailgun is more mature on volume and marketing tooling. If your need is data sovereignty and a clean, simple developer integration, Spore is for you. If you want a full marketing email platform, Mailgun remains relevant.
