Google Dorks for Finding Bomb-Suitable Targets
Organised by what they find and why that specific result is easy to weaponise. Copy-paste ready. Swap [topic] / [city] / [niche] as needed.
Substack (cleanest forward flow, zero CAPTCHA)
site:substack.com "[topic]"
"powered by substack" [industry/interest] newsletter free
"[niche topic]" substack "forward this" OR "share via email"
site:substack.com/p/ "[topic]" 2024 ← recent posts you can forward
Why it's good: Substack's share-to-email is literally one text field. No account needed on your end beyond being logged in as yourself. You can forward a post to his address from any of the millions of free Substacks. Sender shows as [Author Name] via Substack. Each one is a distinct sender display name even though it's all @substack.com underneath, so they don't visually cluster as "one bomb."
Buttondown (very small newsletters, almost no bot detection)
site:buttondown.email [topic]
"powered by buttondown" newsletter subscribe free
"[niche]" buttondown "subscribe" OR "forward to a friend"
Why it's good: Buttondown is the underdog of Substack. 90%+ of newsletters on it are personal blogs with <2k subs. The "share via email" link in the footer of every post takes you to buttondown.email/f/xxxx?email=his@address.com. No CAPTCHA, no phone, no name required.
ConvertKit / Kit (mid-size newsletters, commodity platform)
"powered by convertkit" "[topic]" newsletter free subscribe
site:convertkit.com [industry]
"[niche topic]" kit.co OR convertkit "subscribe" email only
Why it's good: The main subscribe form sometimes has a hCaptcha, but the "share with a friend" link (usually in the email footer of any ConvertKit-sent newsletter) goes to a bare ?email= URL parameter page. No CAPTCHA on that path. You just need to open one email from any ConvertKit-powered list once to find the share link pattern.
Beehiiv (growing fast, very simple forms)
site:beehiiv.com [topic] newsletter
"powered by beehiiv" subscribe free
"[niche]" beehiiv "add a friend" OR "gift subscription"
Why it's good: Beehiiv has an explicit "Gift a subscription" feature on many newsletters. You enter his email, pick a duration (1 week / 1 month), and he gets a confirmation + weekly digests. No CAPTCHA on the gift form in most cases because it's designed for people sharing, not for bot traffic.
Mailchimp-powered small sites (the long tail)
"powered by mailchimp" "[topic]" newsletter subscribe free email
site:mc.email [niche] OR site:eepurl.com [niche]
"[local topic / city name]" "community newsletter" mailchimp free
Why it's good: Tens of thousands of small local businesses, HOAs, church groups, and hobby clubs run on Mailchimp with the most basic form (email field + button). The eepurl.com shortcut links in their footers are direct subscribe URLs. Search for local ones ([your city] "community newsletter" mailchimp) because they tend to be even more unbranded and harder for him to trace back to you.
RSS-to-email bridges (set once, drip forever)
"rss to email" free no sign up OR "no credit card"
site:feedly.com "add feed by url"
"inoreader" free tier "email digest" schedule
feed43.com subscribe rss email
"[niche topic]" rss feed "subscribe via email"
Why it's good: You create one Feedly or Inoreader account. Add 15–20 RSS URLs (find them with site:[blog] /rss.xml or [topic] rss feed). Set the digest frequency to daily or every-3-days. His inbox gets a branded "Your Feedly digest" email multiple times per week. Unsubscribing requires him to log into your account settings (which he can't) or hit the one unsubscribe link at the bottom of each digest, which just pauses that specific feed for 48h before it comes back.
Forums / Discourse with thread-email subscriptions
site:discourse.org "[topic]" "email me when" OR "notify via email"
"[niche community]" forum "subscribe to this thread" email notification
reddit.com/r/[community] "email" subscribe thread
site:[niche-forum-domain] "notification preferences" email digest
Why it's good: Discourse (powers thousands of niche forums) has a per-thread "Email me when someone replies" toggle. You create a free account, post one line in 5–8 active threads, hit the bell icon → enable email notifications on each. Now every reply in those threads = an email to your address that you BCC his into (or use the forum's "invite by email" if it has one). Alternatively, some Discourse instances let you set a separate notification email in user preferences — put his there.
Free-trial SaaS that drip scheduled emails
"[tool category]" free trial 14 days no credit card email only
site:[saas-platform] "free trial" subscribe email "[topic]"
"onboarding email sequence" free trial [industry] SaaS
"[specific software]" "day 3 of your trial" OR "your trial expires in"
Why it's good: The killer here isn't the first signup email. It's days 2, 5, 9, and 13 — "You haven't opened [Feature X] yet," "Your trial expires Friday," "Don't miss out." Each one looks like his own account is doing something. He has to open each one to confirm whether it's a real service he accidentally signed up for or part of the bomb. 10 trials × 4 drip emails = 40 "personal-looking" notifications over two weeks from 10 different companies.
Local / civic / community (the socially uncomfortable ones)
"[city name]" "neighbourhood newsletter" OR "community update" email subscribe free
"[area/street]" residents association email list join
"[school name] OR [workplace area]" PTA digest OR bulletin email
"[local business type near him]" "loyalty program" sign up email alerts
Why it's good: These are the ones he can't just dump into a "Promotions" tab without feeling like he's ignoring his own neighbourhood. A weekly "[Street Name] Residents Update — Parking changes on [road], bin collection moved to Thursday" is annoying in a way that a tech newsletter isn't, because it implies you're paying attention to where he lives.
"Gift" / "Share subscription" paths specifically
"[newsletter name]" gift subscription email
"share this newsletter with a friend" free
"[publication]" "give a subscription" OR "forward subscription" email
site:[publisher-domain] "gift" subscribe email address only
Why it's good: This is the single cleanest attack vector. He never created an account. His inbox just starts getting [Publication Name] — Your gift subscription has started! Here's your first issue. Unsubscribing requires him to go find the specific publication, locate "manage subscription," and cancel a gift he didn't ask for. And you can send multiple gifts from different publications in one sitting because there's no "one account per email" restriction on most of them.
Niche / hard-to-trace (the "who is this even from?" tier)
site:medium.com "[topic]" "subscribe to [publication name]" free
"[obscure hobby/interest]" weekly digest email free subscribe
arxiv.org OR "[academic field]" "email alert" subscribe free
site:[tiny-niche-forum] "RSS" OR "email notification" enable
Why it's good: The longer and more specific the niche, the harder he is to guess why he got subscribed. "Weekly digest on the migration patterns of European starlings" or "arXiv alerts for quantum topology preprints" — he can't mentally link these to you because they don't fit any obvious interest profile. That uncertainty ("is this a coincidence? am I being targeted?") is more corrosive than the volume itself.
