Notify vs Resend for password reset and notification emails: which should I choose?

If you’re choosing between Notification/Transactional APIs like Resend and AWS SES (or other email infrastructure) for password reset and notification emails, the best choice usually comes down to speed of setup vs control/cost/scale.

Short answer

• Choose Resend (or a similar transactional email service) if you want:

  • fastest setup
  • great developer experience
  • simple password reset / auth emails
  • decent deliverability without much ops work

• Choose AWS SES if you want:

  • lower cost at scale
  • more control over infrastructure and sending
  • tighter AWS integration
  • you’re okay with more setup and deliverability management

For password reset + notification emails specifically

These are transactional emails, not marketing emails. That means you care most about:

• deliverability
• low latency
• reliability
• domain authentication (SPF, DKIM, DMARC)
• ease of retry/monitoring

For most small-to-medium products, Resend is usually the better default choice because it’s simpler and more developer-friendly.

Why Resend is attractive

• Very easy API
• Good templates and React/email workflow
• Better UX for developers
• Less AWS complexity
• Good enough for most transactional use cases
• Usually faster to get live

Why AWS SES is attractive

• Very low sending cost
• Mature and scalable
• Strong if your app already lives in AWS
• Good for high-volume sending
• More flexible if you build your own mail pipeline

Important consideration: “notification emails”

If by notification emails you mean things like:

• password reset
• account verification
• alerts
• receipts
• login alerts

then these are all still transactional. A transactional provider like Resend is a strong fit.

If you mean:

• bulk updates
• product newsletters
• marketing campaigns

then you’ll want a separate marketing tool. Don’t mix marketing with transactional email streams if you care about deliverability.

My recommendation

Pick Resend if:

• you’re an early-stage startup
• you want to ship quickly
• you send modest volume
• you don’t want email infrastructure overhead

Pick SES if:

• you already use AWS heavily
• you send lots of emails
• cost matters a lot
• you have engineering bandwidth to manage setup/deliverability

Practical rule of thumb

• < 100k emails/month and you want speed: Resend
• high volume or cost-sensitive: SES

Best practice either way

No matter what you choose:

• authenticate your domain with SPF, DKIM, DMARC
• use a dedicated sending domain/subdomain
• separate transactional from marketing
• monitor bounce/complaint rates
• include clear sender identity and support info
