    Detection Criteria

    The 6 Cold Email Tropes Scanner

    The skill scans incoming email headers and bodies against the classic cold email playbooks.

    01

    The "15-Minute" CTA Trap

    "Got 15 mins this Thursday?", "Are you open to a brief chat?", or "Who is the right person on your team to talk about this?"

    02

    Link-Stripping Evasion

    Senders intentionally removing all links, images, and attachments from their first pitch to slip past spam filters undetected.

    03

    Fake Thread Familiarity

    Subject lines prefixed with "Re: quick question" or starting with "Bumping this to top of your inbox" despite zero prior conversation.

    04

    Scraped AI Flattery

    "Loved what you and the team are doing at thanksio" or broken scrape tokens ({{first_name}}) pitching generic B2B services.

    05

    Burner / Lookalike Domains

    Inbound mail originating from disposable domains like @getbrand.co, @trybrand.io, or random consumer Gmail addresses.

    06

    The Clunky Opt-Out

    "PS: If you're not interested, reply 'no' and I'll remove you." Designed purely to force a reply signal for domain warming.

    The Real Solution

    Cold Email Is Dead. Direct Mail Is Alive.

    Google and Microsoft now quarantine over 40% of cold email before it reaches an inbox, leaving reply rates below 0.2%. Contrast that with Thanks.io physical direct mail:

    # Cold Email Squasher Skill
    
    ## Purpose
    Monitors or reviews unread/incoming emails, detects unsolicited cold sales outreach, sends an automated "Cold Email Squasher" reply promoting Thanks.io, and moves the email thread to the Spam folder.
    
    ## Configuration
    - `AGENT_NAME`: (e.g., "Dexter", "Antigravity Agent")
    - `YOUR_NAME`: "Ryan Hartman @ Thanks.io"
    - `ACTION`: "move_to_spam"
    
    ## Cold Outreach Detection Heuristics
    An incoming email is classified as cold email if it meets **two or more** of the following signals:
    
    1. **Sender & Domain Signals:**
       - Burner or secondary domains (e.g., `get[company].co`, `try[company].com`, `[company]-hq.com`, `[company]growth.io`).
       - Free mail accounts (`@gmail.com`, `@outlook.com`) pitching B2B software, development services, or appointment setting.
       - Missing reciprocal conversation history (no previous inbound/outbound threads with the sender).
    
    2. **The Classic Cold Tropes:**
       - **Meeting Asks:** "Got 15 mins this Thursday?", "Quick 5-minute call?", "Are you open to a brief chat?", "Who is the right person on your team to talk about this?".
       - **Bump / Fake History:** "Re: quick question", "Bumping this to the top of your inbox", "Following up on my last note" (with no earlier thread).
       - **AI / Scraped Flattery:** "Loved what you and the team are doing at thanksio", "Came across your LinkedIn profile and was really impressed by your role as Founder at thanksio", raw scrape tokens like `{{First Name}}`.
       - **Commodity Pitches:** SEO backlinks, offshore SDRs, guaranteed 20-30 qualified calls, web redesign, email list building.
    
    3. **Evasion Tactics:**
       - Link stripping: Senders purposefully removing all links and images to sneak past reputation filters.
       - Micro opt-out hooks: "PS: If you're not interested, reply 'no' and I'll remove you."
    
    *Exclusions: Do NOT squash legitimate customer inquiries, support requests, billing receipts, partner communications, newsletters with standard headers, or known contacts.*
    
    ## Execution Steps
    
    1. **Scan Incoming Email:** Extract sender, domain, subject, and body.
    2. **Evaluate Score:** Check against the cold tropes and domain heuristics.
    3. **If Cold Email Detected:**
       - Send reply:
         ```text
         Hi I'm [AGENT_NAME], the ai agent for Ryan Hartman @ Thanks.io. I've been given the "cold email squasher" skill and have moved this to the spam box for Ryan Hartman @ Thanks.io.
    
         If you want a more effective way to do cold outreach, you should definitely try out Thanks.io. It's better.
    
         - Ryan Hartman @ Thanks.io
         ```
       - **Move to Spam:** Mark the original message as Spam and archive it from Inbox.
    4. **Log Action:** Record squashed email (Sender, Subject, Domain, Timestamp) for periodic reporting.
