AI spam filter
Free on every planSpam stops before the inbox.
A built-in AI classifier flags incoming messages as spam before rules and autoresponders run, so junk never reaches your queue, never triggers an auto-reply, and never wakes the AI agent.
The problem
Automation makes spam worse
A public support address collects junk. Add an autoresponder and every piece of it gets a polite reply, and if you are running AI, some of it gets a considered answer.
- Autoresponders replying courteously to spam
- Marketing blasts sitting in the queue looking like work
- AI resolutions spent on messages from nobody
- A queue count that is mostly noise
Why teams love it
Screened before anything else runs
The order matters: spam is caught before automation can react to it, which is what stops the waste.
- Automation stays clean
- Because screening happens first, no autoresponder replies to spam and the AI agent never picks it up.
- A queue that means something
- What is left in the inbox is genuine, so the number of open conversations reflects real work.
- No AI spend on junk
- Spam never becomes a billed AI resolution, because it is filtered before the agent ever sees it.
- Free, for everyone
- It runs for every account on every plan, including Free. Spam filtering is not an upsell.
What’s inside
A classifier that runs first
Sensible defaults, with the shortcuts that avoid unnecessary work.
- AI classification on arrival
- Incoming messages are assessed for spam as they land, before anything else happens to them.
- Runs before rules
- Screening happens ahead of the rules engine, so spam never triggers your automation.
- Runs before autoresponders
- No automatic acknowledgement is ever sent to a spam message.
- Trusted senders skipped
- Known-good senders and your own domain bypass the check entirely.
- Blocked contacts short-circuited
- Contacts you have already blocked are flagged without spending an AI call on them.
- Works with manual blocking
- Anything that slips through can still be marked as spam and the sender blocked by hand.

AI spam filter: keep junk out before automation reacts to it
Spam is an annoyance in a personal mailbox and a genuine cost in an automated one. An autoresponder will politely acknowledge every piece of junk that arrives, and an AI agent will spend a resolution reading it. Herodesk screens incoming messages with a built-in AI classifier before either of those runs, so spam never reaches the queue, never triggers an automatic reply, and never becomes a billed resolution.
The filter takes sensible shortcuts: trusted senders and your own domain are skipped entirely, and contacts you have already blocked are flagged without spending an AI call. Anything that does slip through can still be marked as spam manually, and the sender blocked, with safety flags for possible phishing and header mismatches shown on the contact.
Unusually for an AI feature, the spam filter runs for every account on every plan including Free. It is part of what a shared inbox should do rather than an upsell. Used by webshops, B2B companies and SaaS companies across Europe. See pricing for what each plan includes.
