SpamHero reduces bulk junk for a whole domain. Immune protects the public and shared addresses that filters still leave open, with a challenge gateway and virtual inboxes that route to the tools your team already uses.
About SpamHero
SpamHero is a cloud spam filter priced per domain. It sits on your MX records and scores inbound mail before it reaches your existing mail host.
| Capability | Immune | SpamHero |
|---|---|---|
| Primary job | Challenge unknown senders on public and team addresses | Score and quarantine spam for an entire domain |
| Virtual addresses | First-class virtual, group, and user inboxes with their own destinations | Aliases/catch-all on top of your existing mail server |
| Unknown senders | Must verify (CAPTCHA or donation) before delivery | Delivered if content and reputation look clean |
| Sales and outreach | Stopped unless the sender completes the challenge | Often delivered because it reads like a real person |
| Routing | Per-inbox destinations (helpdesk, Gmail, SMTP) | Passes cleaned mail to your existing host |
| Pricing model | Inboxes and volume protected | Per domain with message caps |
