How to Build a Cold Email Swipe File

A swipe file is a curated collection of effective cold emails that serves as ongoing inspiration.

What to collect

Cold emails you receive that catch your attention. Emails shared in cold email communities (Reddit, LinkedIn, Slack groups). Emails from case studies and articles. Your own best-performing emails with their metrics.

How to organize your swipe file

By industry: Emails targeting SaaS, healthcare, finance, etc. By persona: Emails targeting CEOs, VPs, directors, etc. By approach: Problem-focused, insight-sharing, social proof, question-based, etc. By sequence position: First emails, follow-ups, breakup emails.

How to use your swipe file

When writing new campaigns, browse your swipe file for structural inspiration. Do not copy emails verbatim — adapt the structure, approach, and energy to your specific product and audience.

Building the habit

Every time you encounter an effective cold email — one that makes you want to reply — save it to your swipe file with a note about why it worked. Over time, you build a library of proven approaches that accelerates your copywriting.
