The best email API for developers. Send transactional and marketing emails with 99.9% deliverability. Simple REST API, competitive pricing, and 5,000 free emails/month. Better than Resend & SendGrid. Start free today.
Hey Product Hunt! 👋
I'm excited to launch Unosend—the email API I wish existed when I started building.
The Problem:
Every email API either charges too much, has confusing pricing, or lacks features developers need. I've used Resend, SendGrid, Resend and Postmark-they're all great but expensive for growing startups.
The Solution:
Unosend gives you:
- 5000 free emails/month
- Transectional and marketing emails.
- Simple, predictable pricing as you scale
- The same reliable infrastructure and deliverability
- A developer experience we're proud of
Why we built this:
As developers ourselves, we wanted an email API that doesn't punish you for success. When your app grows, your email costs shouldn't eat into your margins.
What's next:
- React Email integration
- More SDKs (Rust, Java, .NET)
- Advanced analytics
- Email automation workflows
I'd love your feedback! Try it free (no credit card needed), and let me know what you think.
Happy to answer any questions! 🚀
Tries to use TLS (either because you told it “SSL/TLS” in the settings or because it does STARTTLS if the server advertises it).
During the TLS handshake it checks the certificate.
The server presents a cert whose hostname is localhost.
Supabase compares that to the host you configured smtp.unosend.co and goes “nope” and throws:
tls: failed to verify certificate: x509: certificate is valid for localhost, not smtp.unosend.co
I don't see a way to contact support anywhere on the site? So I am posting here to hopefully make the devs aware of this issue and resolve it?
@bittucreator@Unosend 99.9% deliverability for transactional and marketing emails is impressive! Email deliverability is such a pain point for businesses, especially as inbox providers get stricter.
How does Unosend achieve such high deliverability rates? Are there built in tools for domain warmup and reputation management?
Curious about how it handles bounce rates and spam complaints to maintain that deliverability level over time.
landing page looks pretty wack on darkmode firefox.
as a paying resend user, why should i switch to unosend?
How does deliverability compare to Resend? Are you likely to end up in spam for gmail or outlook? Additionally, do you have any protection in place to prevent people abusing the service, and then get the other people using the service to be marked as spam?
pricing feels fair, especially for small projects that still need professional delivery.
My recommendation would be to change up the UI a little, it feels like a clone of resend (which I currently use) and I think that could hurt the trust of customers who already know Resend.
I'm really interested in using it for a Waitlist🙏🏽my flow is: user signs up, unosend collects the email as contact, unosend sends Email confirmation to user, 1 week later Unosend automatically sends a reminder to All users. Can I create all that with Unosend alone?
I went through your Docs, I think Unosend can do all that. Just wanted a short confirmation before I start hacking.
Resend forces me to buy webhooks externally (zapier, supabase, mailchimp) which for me defeats the purpose of using Resend at all.
Do you offer tracking, and also is there a way to detect if the mail has landed in spam? Would love to try it
So the only thing this one better than Resend is the number of free emails?
Nice project, @bittucreator! It’s much-needed. I also love the simple and clean UI. Congratulations on a successful launch!
Do you have any plans for a PHP/Laravel package or library that can be used to send emails using UnoSend?
Well done Venkat. Unosend is clean and practical. Congrats to you and the team.
