Yes—sometimes, for a limited volume.
Free options
Many email providers offer a free tier for transactional emails, usually with limits like:
- a monthly sending cap
- daily sending limits
- branding in the emails or dashboard
- limited support or features
Examples of services that often have free tiers or trials:
- Amazon SES (very cheap; not really “free” except during AWS free tier conditions)
- Brevo (Sendinblue)
- Mailjet
- Resend
- SendGrid (availability of free tier changes over time)
What “transactional emails” usually include
These are non-promotional emails triggered by an action, like:
- password resets
- account verification
- receipts / invoices
- order confirmations
- shipping updates
Important caveats
- Free tiers may be enough for a small app or MVP, but not for production at scale.
- You still need proper email authentication:
- SPF
- DKIM
- DMARC
- Some providers require a verified domain and may suspend accounts for abuse.
- Transactional email should not be mixed with marketing email without following the provider’s rules.
Best “free” route
If you only send a small number of emails, a provider with a free tier is usually easiest.
If you expect growth, Amazon SES is often the cheapest long-term choice.
If you want, I can recommend the best free/cheap transactional email provider based on:
- your monthly email volume,
- your tech stack, and
- whether you need API or SMTP.
