5 email copywriting formulas we A/B tested across 100 campaigns
We tested 5 popular copywriting formulas across 100 email campaigns to see which performed best for email specifically.
The formulas tested
- PAS (Problem-Agitate-Solve): State the problem, amplify the pain, offer the solution
- AIDA (Attention-Interest-Desire-Action): Classic funnel progression
- BAB (Before-After-Bridge): Current state → desired state → how to get there
- 4Ps (Promise-Picture-Proof-Push): Make a promise, paint a picture, prove it, push to action
- The Story Formula: Personal anecdote leading to the point
Results
- Best click-through rate: PAS (4.1% average CTR)
- Best conversion rate: BAB (2.3% average conversion)
- Best for long-form: Story Formula (highest read-through rate)
- Most consistent: PAS — performed well across all email types
PAS works best for email because the medium is short. You have 3-5 seconds to hook the reader. Starting with their problem is the fastest way to establish relevance.
