Transactional email API — 3K/mo free, behind @chirag127/email-send

Resend

Role

Sends transactional email — sign-in links, receipts, contact-form auto-replies. Wrapped behind @chirag127/email-send.

Free tier

• 3,000 emails / month
• 100 emails / day cap
• 1 verified sending domain
• Unlimited team members

Card / subscription required?

NO. Free tier sign-up requires only an email-verified account plus DNS verification on the sending domain. No payment method on file. Audit confirms.

Alternatives

• AhaSend (1K/mo, unlimited domains)
• Brevo (9K/mo)
• Maileroo
• MailerSend

Swap cost

Low — all alternatives expose a similar from / to / subject / html REST API. The @chirag127/email-send wrapper hides the difference.

Why this is our pick

Cleanest API, fastest sandbox-to-production path, React-email integration is a nice-to-have we may use.

Cross-refs

• No card-on-file rule
• MailerLite — for marketing email, not transactional
