For a solo developer, the simplest setup relies on Resend (or Postmark) paired with a domain DNS record for authentication.
1. Top Email Providers for Solo Devs
| Provider | Best For | Free Tier / Starting Price | Why Choose It |
|---|---|---|---|
| Resend | Modern Dev Experience | 3,000 emails/mo free | Extremely simple API, React Email integration, fastest onboarding |
| Postmark | Rock-solid Reliability | 100 emails/mo free, then $15/mo | Industry-best delivery rates for critical emails (password resets) |
| AWS SES | Scale & Lowest Cost | $0.10 per 1,000 emails | Dirt cheap at scale, but setup/UI is more tedious |
Recommendation: Start with Resend unless deliverability for mission-critical transactional mail is your absolute top priority, in which case go with Postmark.

Key Best Practices
- Separate Transactional & Marketing: Never send promotional blasts from your transactional domain/subdomain. If you send newsletters later, use a separate subdomain like
mail.yourdomain.comornews.yourdomain.com. - Use Clean HTML / React: If using Node/Next.js, tools like React Email let you design clean email templates as simple React components instead of wrestling with legacy table-based HTML.
