For a small SaaS, the most affordable and practical email services are usually:
Best low-cost options
- Amazon SES — cheapest at scale, very good deliverability, but more technical to set up.
- Brevo (Sendinblue) — easy to use, good for transactional + marketing emails, generous free tier.
- Mailgun — solid for transactional email, simple API, but can get pricier than SES.
- Postmark — excellent deliverability and developer experience, but not the cheapest.
Quick recommendation
- If you want the lowest cost: Amazon SES
- If you want easiest setup + low cost: Brevo
- If your app sends mostly transactional email: Postmark or Mailgun
- If you’re very cost-sensitive and technical: Amazon SES
What to compare
Look at:
- price per 1,000 emails
- free tier
- transactional vs marketing support
- deliverability
- bounce/complaint handling
