1. Deliverability
Deliverability is a key factor when choosing a transactional email service. A platform must reliably get emails into inboxes, not just offer good pricing and features.
Both Amazon SES and Resend provide strong deliverability, but their approaches are different.
Amazon SES Deliverability
Amazon SES uses AWS infrastructure to provide reliable email delivery at scale. Its strengths include:
- Strong sending infrastructure
- SPF, DKIM, and DMARC support (a free DMARC record generator can help you configure this quickly)
- Dedicated IP options
- Reputation monitoring tools
However, SES requires more technical management. Businesses must properly configure authentication, maintain sender reputation, and monitor email performance.
Resend Deliverability
Resend focuses on making transactional email delivery simple for developers. Its advantages include:

Both platforms can deliver excellent results when properly configured.
2. Ease of Use Comparison

Amazon SES offers powerful email infrastructure, but it requires more technical setup. Users need to configure domains, DNS records, authentication, sending limits, and reputation monitoring — our email sending server setup guide covers the basics if you’re doing this for the first time.
While experienced AWS users can manage this easily, beginners and small teams may find the setup process complex.

Resend Pricing
Resend uses subscription-based plans with included email limits. Its pricing is simpler and more predictable, making it easier for startups and smaller teams to budget.
