What should I use instead of SendGrid for a product app?

If you’re looking for an alternative to SendGrid for a product app, the “best” choice depends on what you need most:

Good alternatives

1. Postmark

• Best for: transactional email
• Great deliverability and simple setup
• Clean APIs and logs
• Usually preferred when you care more about reliability than marketing features

2. Amazon SES

• Best for: low cost at scale
• Very cheap, highly flexible
• Strong if you already use AWS
• Tradeoff: more setup and less polished UX than SendGrid

3. Mailgun

• Best for: developer-friendly email delivery
• Good APIs, routing, testing tools
• Often used for product apps and SaaS
• Can be a bit more expensive depending on usage

4. Brevo (Sendinblue)

• Best for: transactional + marketing in one tool
• Easier if you want email campaigns too
• Solid all-around option for small to mid-size products

5. Resend

• Best for: modern product apps and startups
• Very developer-friendly
• Good DX, especially for React/Next.js ecosystems
• Strong choice if you want a newer, simpler tool

My quick recommendation

• Transactional email only: Postmark or Resend
• Lowest cost: Amazon SES
• Transactional + marketing: Brevo
• Balanced developer option: Mailgun

If you want the short answer

For most product apps, I’d pick:

1. Postmark if email reliability is your top priority
2. Resend if you want a modern API and fast developer experience
3. Amazon SES if cost matters most

If you want, I can also recommend one based on your stack:

• Next.js / Node
• Python
• Laravel
• Rails
• High-volume SaaS
• Marketing + transactional
