Klar vs EuropeanMX
What actually differs: where each filter runs, who gets to read your mail, and what it costs.
| Aspect | Klar | EuropeanMX |
|---|---|---|
| Runs on | Your Mac | EuropeanMX's cloud |
| Who can read your mail | No one new during filtering. Classification stays on your device. | EuropeanMX can technically access email data; it says valid messages are not retained unless archiving is enabled |
| Works with | Apple Mail, with any account: IMAP, Gmail, iCloud, Exchange | A domain's mail flow, including Microsoft 365, Exchange and self-hosted mail servers |
| Price | Free forever | From €4.95/month plus VAT for one domain, billed annually |
Klar fits better when you are an individual reading mail in Apple Mail and do not want to reroute a domain through a cloud gateway
The honest picks
- EuropeanMX
- A managed business gateway for inbound and outbound filtering, malware and phishing protection, IP reputation and optional archiving. Pick it when an organization needs one cloud layer in front of every mailbox. It is not a personal Apple Mail tool.
- Klar
- Pick Klar if you read mail in Apple Mail and want a modern multilingual model that runs entirely on your Mac. No account, no cloud, nothing to hand over.
