An AI email filter that blocks sales pitches and lets real customers through.
OwlReply reads every new email, works out what it actually is, and sorts it for you. Cold sales emails, marketing blasts and spam leave your inbox. Real questions from real people stay put, with an AI reply already drafted.
Your spam filter was never built to stop sales emails.
Traditional spam filters look for bad links, spoofed senders and known junk. A cold sales email doesn't trip any of that. It comes from a real domain, a real person wrote it (or an AI did), and it's personalized with your name and company. It lands in your primary inbox, right beside the customer who wants to buy something.
Unsubscribe links don't stop it either. Every outreach tool, lead list and "partnership" agency is a new sender. Blocking them one at a time never ends.
- Cold outreach and sales sequences that follow up three, four, five times.
- "Quick question" emails written to look like a customer inquiry.
- SEO, web design and lead-gen pitches sent to your contact form address.
- Newsletters and promos you never signed up for.
- Automated notifications that bury the messages that matter.
- Blatant spam that got past your provider.
It reads the email, the way a person would.
OwlReply doesn't rely on blocklists or keyword rules. An AI model reads each message and decides what kind of email it is from its content and intent, then OwlReply acts on that decision in your mailbox.
Connect your inbox
Sign in with Google for Gmail, or connect any other provider over IMAP. OwlReply keeps checking for new mail from then on.
AI reads each new email
Every new message goes to the AI with your category rules. It judges intent: is this person asking you something, selling you something, or is it a machine sending a notification?
It gets a category
The AI picks exactly one category. If the answer is unclear or unusable, the email goes to Uncategorized instead of being guessed at.
Your inbox gets sorted
OwlReply labels the email in Gmail or files it in IMAP, archives junk out of your inbox, and drafts a reply wherever one is needed.
Four categories to start with, and you can change all of them.
OwlReply comes with a set of categories that suit most businesses. Each one has a label, a rule the AI follows, and an action: draft a reply, archive it, or leave it alone.
Substantive
A real person asking you something: a customer, a lead, a supplier, a partner. These are the emails you actually need to answer, so OwlReply writes a draft reply using your business information and leaves it waiting in your drafts.
Also covered: replies to automated messages you sent, such as a customer answering your order confirmation. The AI is told to tell these apart from true notifications so they don't get ignored.
Marketing
The sender is trying to sell you something or get you to sign up for a service. Cold sales emails, outreach sequences, agency pitches, promotional blasts and blatant spam all end up here.
What happens: the email is labeled and archived out of your inbox, so you never see it unless you go looking. It isn't deleted, and it can always be found under its label.
Automated
Clearly machine-generated notifications: password resets, shipping updates, receipts, payout notices, terms-of-service updates. Useful, but nothing to reply to.
What happens: labeled so you can scan or filter them at a glance. No AI reply is drafted, so you never get a draft addressed to a no-reply address.
Other
Anything that doesn't fit the categories above and definitely shouldn't get a reply, such as FYIs, internal announcements or one-way updates.
What happens: labeled and left in place. You decide what to do with it.
Custom email categories, written in plain English.
Every business gets different mail. A recruiter wants job applications separated out. A landlord wants maintenance requests flagged. An agency wants to keep client emails away from vendor pitches.
In OwlReply you describe a category the same way you'd explain it to an assistant. That description becomes a rule the AI follows. For each category you choose whether matching emails get a draft reply and whether they're archived out of the inbox.
Rename labels without breaking anything. The name you see in Gmail and the internal name the AI classifies with are stored separately. Call Marketing "Junk", "Sales Pitches" or "Ignore", and classification keeps working the same way.
Label: Job Applications
Rule: An email is job_applications if someone
is applying for a role or sending a resume.
Draft a reply: yes
Archive from inbox: no
# Retune a built-in category
Label: Sales Pitches ← renamed from Marketing
Rule: ...trying to sell you something. Treat
emails offering "guest posts" or "backlinks"
as marketing too.
Archive from inbox: yes
More than a spam filter, more than an AI email writer.
Classification is what the rest of OwlReply runs on. Because it knows what each email is, OwlReply only drafts replies where a reply makes sense.
Sales email blocker
Cold pitches and outreach sequences are recognized by what they're trying to do, not who sent them, so new senders get caught too.
AI replies only where they belong
Drafts are written only for categories you choose. No wasted drafts for newsletters, receipts or no-reply addresses.
Gmail labels & IMAP folders
Each email is stamped with its category in your real mailbox. Search it, filter it and view it from any email app or phone.
Auto-archive junk
Turn archiving on for any category. Emails are moved out of the inbox, never deleted, so nothing is gone for good.
Per-category behavior
Every category has its own switches for drafting and archiving. Turn off categories you don't need and add new ones.
Safe by default
If the AI isn't sure, the email lands in Uncategorized, left in your inbox and untouched. Unclear messages are never archived.
Defaults that keep improving
Built-in categories you haven't changed pick up our improvements automatically. Anything you've customized stays as you set it.
Optional automatic replies
On IMAP accounts, you can let OwlReply send replies on its own for categories you trust. It's off by default, and editing your settings pauses it.
Always running
OwlReply keeps checking your inbox in the background. There's no plugin to install and no browser tab to leave open.
AI classification vs. the usual ways to filter email.
Filters and blocklists match patterns. OwlReply looks at what the email is trying to do.
| Built-in spam filter | Manual rules & blocklists | OwlReply AI classifier | |
|---|---|---|---|
| Catches cold sales emails from new senders | Rarely | Only after you block each one | Yes, judged by content |
| Tells a customer apart from a pitch | No | No | Yes |
| Setup effort | None | Ongoing upkeep | Connect and go |
| Custom categories in plain English | No | Keyword rules only | Yes |
| Drafts replies to real questions | No | No | Yes, using your business info |
| What happens to filtered mail | Spam folder | Whatever the rule says | Labeled & archived, never deleted |
Built for inboxes that are open to the public.
If your email address is on a website, a storefront or a contact form, it's on sales lists too.
Small businesses
Keep info@ and support@ for customers, not SEO agencies and "growth partners."
Online stores
Order questions get a drafted answer. Platform notifications get labeled. App-developer pitches get archived.
Founders & executives
Stop losing investor and customer emails in a pile of vendor outreach.
Agencies & freelancers
Separate client requests from people trying to sell you the service you already sell.
Questions about the AI email classifier
How does OwlReply block cold sales emails?
Each new email is read by an AI model along with your category rules. When the email is trying to sell you something or get you to sign up for a service, it's classified as Marketing, labeled, and archived out of your inbox. It doesn't depend on who sent it, so cold emails from brand-new senders are caught too.
Will it delete my emails?
No. OwlReply never deletes email. Filtered messages are labeled (Gmail) or filed (IMAP) and moved out of the inbox, so you can always find them under their category label.
What if it gets an email wrong?
If the AI's answer doesn't match one of your categories, the email goes to Uncategorized and stays in your inbox. If an email type keeps getting sorted the wrong way, edit that category's rule in plain English to tell the AI how to handle it.
Does it work with Gmail and Google Workspace?
Yes. Connect with Google and OwlReply applies Gmail labels, archives filtered mail, and saves AI replies as drafts in your account. Other providers such as Outlook, Yahoo, Fastmail or your own mail server connect over IMAP.
Can I create my own categories?
Yes. Add a category with a label and a plain-English description of which emails belong in it, then choose whether those emails get a draft reply and whether they're archived. You can also rename, retune or switch off the built-in categories.
Does OwlReply send replies automatically?
Not by default. Out of the box, OwlReply writes drafts for you to review and send. IMAP accounts can turn on automatic sending for specific categories, and any change to your settings pauses it until you turn it back on.
Is this different from an AI email assistant?
Most AI email assistants help you write replies once you've opened an email. OwlReply works earlier: it decides which emails deserve your attention at all, clears out the junk, and has replies drafted before you open anything.
