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! 🚀

@bittucreator Advanced analytics could be super useful.
The free tier is definitely a highlight (5,000 emails/month vs Resend's 3,000), but there's more:
Beyond the free tier:
💰 Better value - $20/mo gets you 50K emails AND 10,000 contacts (Resend's $20 only gives you 50K emails, no contacts included)
🚀 Higher rate limits - 50 emails/sec vs Resend's 10/sec
🔌 Same simple API - If you know Resend, you already know Unosend (drop-in compatible)
Same great features:
Beautiful developer experience
Webhooks, tracking, templates
React Email support
All the SDKs you need
We built Unosend because we love what Resend did for email DX, but felt the pricing was holding back indie hackers and startups. Same philosophy, friendlier on the wallet 🙌

@bittucreator Thank you for the details information. I think you should include this somewhere in the website, for users to compare
Open tracking - Know when recipients open your emails
Click tracking - Track which links get clicked
Delivery webhooks - Real-time notifications for delivered, bounced, and complained events
About spam detection: Directly detecting if an email lands in spam isn't possible (no email provider can do this - it's determined by the recipient's mail server). However, we help you maximize inbox placement:
📊 Bounce & complaint monitoring - High rates often indicate deliverability issues
🔐 Full authentication - We handle SPF, DKIM, and DMARC automatically
📈 Sending reputation - Our infrastructure maintains high sender reputation
If you're seeing deliverability issues, the complaint/bounce rates in your dashboard are usually the best indicators.
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?
Dark mode bug: Thanks for flagging - will fix that ASAP.
Why switch from Resend:
✅ Multiple projects with own domains - Yes, built-in ✅ Simple API - Same RESTful simplicity you're used to ✅ Deliverability metrics - Opens, clicks, bounces, complaints ✅ Idempotency - Coming soon ✅ Best practices check - On the roadmap
What you get that Resend charges extra for:
Contacts/Audience - built-in, no external DB needed
Broadcasts - send to all contacts natively
Webhooks - included, no Zapier required
Pricing: More generous free tier + lower costs at scale.

Your landing page is partly broken
@jim_engine It looks like a dark mode thing, but yeah the styles do look a bit broken.
Unosend
@jim_engine @raddydev
Yes, Landing page doesn't have dark mode.

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?
Unosend
@hasin
Thanks so much! Really glad you like the clean UI - we put a lot of effort into making it developer-friendly 🙏
Great question about PHP/Laravel! Yes, we have a PHP SDK ready to go:
For Laravel specifically, you can also use it as a mail driver.
We're working on a dedicated Laravel package with Mailables support and would love your feedback on what features would be most useful!
Check out our docs: https://unosend.com/docs
So the only thing this one better than Resend is the number of free emails?

Do you offer tracking, and also is there a way to detect if the mail has landed in spam?
Would love to try it

@chilarai
Thanks for the interest! 🙌
Yes, we offer tracking!

@joshh_founder
Deliverability:
We run our own email infrastructure - full control over IPs and reputation. Proper SPF, DKIM, DMARC is automatic for every verified domain.
Abuse Prevention:
Domain verification required before sending
Rate limiting & bounce monitoring
Separate IP pools - bad actors don't affect you
Dedicated IP option on Scale/Enterprise plans
Bottom line: Verified domain + our authentication = inbox delivery. We maintain our IP reputation and isolate problematic accounts to protect everyone.

landing page looks pretty wack on darkmode firefox.
as a paying resend user, why should i switch to unosend?
My Financé
here are some features that are fairly table stakes to me:
- be able to have multiple projects with their own domains
- simple API
-deliverability metrics
- (nice to have) some idempotency protection
-( nice to have) a sense of best practices and if my emails meet them
