Why people switch to Curo
- Curo decides what deserves your attention instead of just sorting it into folders you still have to read.
- Drafts come back in your actual voice, not generic AI phrasing or canned templates.
- End-to-end encryption is the default, not an add-on or a partial feature.
- The teaching loop means triage gets sharper the more you use it, without writing rules by hand.
Spark is an excellent choice if you want a polished smart inbox with strong team collaboration features. Choose Curo if you want an AI that actually triages your mail down to what needs you, drafts in your voice, and keeps everything end-to-end encrypted.
Questions
Is Curo a drop-in replacement for Spark?
Curo replaces the core job of reading and managing your inbox across accounts. If you rely heavily on Spark's team comment threads, evaluate Curo for the individual triage and drafting workflow first.
Does Curo work with multiple email accounts like Spark?
Yes. Curo unifies all your accounts in one place regardless of provider, then triages across all of them at once.
How is Curo's privacy different from Spark's?
Curo is end-to-end encrypted and private by design. Spark encrypts data in transit and at rest but processes some data on its servers to power smart features.
Will Curo write emails that sound like me?
Yes. Curo learns your writing voice and drafts replies that match it, rather than relying on generic templates or assist suggestions.
