Online Marketplace Email Marketing Benchmarks
Online marketplaces face a unique email marketing challenge: they must communicate effectively with two distinct audiences — buyers and sellers — each with different needs and expectations. Email serves both acquisition and retention functions for both sides of the marketplace.

| Buyer Conversion Rate | 1.5-4% | 6%+ | 10%+ |
| Bounce Rate | 0.5-1.5% | Below 0.3% | Below 0.15% |
| Unsubscribe Rate | 0.3-0.7% | Below 0.2% | Below 0.1% |
Key Findings

- Segment all email communications by role — buyer, seller or both — with distinct content strategies for each
