Every ad in LinkedIn's Ad Library was paid for. So the library is a free list of companies with a marketing budget, and each one hands you its own pitch to write your first line from.

3 steps
1 copy-paste prompt
1. Find companies that pay for ads
Open the LinkedIn Ad Library. Google "LinkedIn Ad Library", or tap the button below. Open the Ad Library →
Type what you sell in the Keyword box. In the Reel I typed "CRM".
Pick your country and hit Search.
In the Reel, "CRM" in the United States showed 77,682 ads on Nov 5, 2026. The count changes every day.
2. Open an ad and copy its words
Click any ad. That's their pitch, word for word. Copy the line with the strongest claim, ideally one with a number in it, and note the company's name.
3. The prompt
Paste this into Claude and fill in the three yellow parts.
Write a 2-line cold email to [company]'s marketing team. Mention their LinkedIn ad: "[paste the ad's words]". I sell [what you sell, in one line]. Just the 2 lines.
In the Reel, Claude already knew my offer from its memory, so I left out the "I sell" part. Add it if yours doesn't know what you sell.
Example from the Reel
Their ad (ServiceTitan): "Learn how Ferguson Roofing & Exteriors grew from $12M to $18M in their first year with ServiceTitan."
The email Claude wrote:
Saw your LinkedIn ad on Ferguson Roofing & Exteriors growing from $12M to $18M in year one; we can put that story in front of thousands more roofing, HVAC and plumbing owners like them, with verified direct emails pulled from our B2B contractor database.

Before you send anything
Send from a second domain, never your main one, so your main domain stays out of spam.
Read every email before it goes out. Claude writes the draft; you're the editor.
Keep it to 2 lines. Their ad in line 1, your offer and one simple question in line 2.
