Link building via cold email is a specialized subset of outbound. The target is other content creators, editors, and marketing ops. The offer isn't a sales call, it's a link placement, guest post, or content swap. Different playbook, same fundamentals.
All are jaded. All get 50+ link-building pitches a week. Generic "your article about X missed my article about Y" emails die on arrival.
"Your [resource page / blog post] links to [dead URL]. I have [relevant replacement]. Want me to send details?"
Strong because you're solving their problem (broken link = bad UX).
"You have a resource page on [topic]. Our [resource] is relevant. Here's why it adds to yours, not just dupes."
Weaker. Only works if your resource is genuinely better/different.
"I'd like to contribute a post on [specific topic]. Here are 3 angle options I've already thought through. Here's my most recent relevant writing."
Works when you bring expertise and have published work to prove it.
"We ran a study on [topic]. Here's the writeup. Thought it'd fit your coverage of [beat]."
Highest-quality links. Requires having done actual research or data collection.
"You mentioned [Company / Product] in [URL]. Noticed it's not linked. If you'd like to link, happy to supply."
Works because you're asking for something trivial.
Subject: broken link on your [topic] page [first line: specific reference to the exact page and broken link] Your resource page at [URL] links to [broken URL] for [topic]. Link's dead (404 confirmed). I wrote an updated piece on [same topic] that might work as a replacement: [URL]. [One-sentence why it's a better fit than the dead link.] Not pushy, just noticed it while researching [their space]. Thought you'd want to know. Sam
Math works because each link is durable value. 20 high-quality links from a 1000-email campaign = months of ongoing SEO value.
Don't mass-send to low-quality sites. Google penalizes unnatural link patterns. Focus on:
Ten links from DR 60+ sites beats 200 links from DR 10- sites.
