Hi PH! I'm Zeno, founder of Resend. We're building a modern email sending platform focused on providing the best developer experience. Why? When you look at all the biggest competitors like Sendgrid, Mailgun, Postmark, and SparkPost, you'll notice that they were all founded around 2009/2010, and they all have been acquired by now. Because of that, it's common to see them only prioritizing enterprise requirements and optimizing for sales-led growth. Nobody is building an exceptional developer experience. Nobody is trying to innovate. There isn't a single developer-first email platform in the market today. We want to change that. Email sending is the kind of thing that you should integrate and forget, but instead, you have… 1. 🛠️ Templates that are hard to build: Typically, you can only send emails using HTML or plain text. Although we support both, we're introducing a new way of developing and sending your emails. With Resend, you can code your email using React instead of outdated layouts thanks to our open source project (https://react.email). 2. 🐢 Slow performance: Current solutions only offer a single region for email sending, even when all your end users are located in another part of the world. We allow you to choose what region your emails should be sent from (US, Europe, or LATAM), which minimizes latency and improves time-to-inbox. 3. 👀 Poor observability: Most tools keep you in the dark without knowing what really happened after you sent an email. Resend exposes all the events associated with your email via webhooks. 4. 🙋 Designed for marketers only: Existing solutions are too generic and built exclusively for product marketers and product managers. We're building a platform with a clean REST API and SDKs for Node.js, Python, Ruby, Elixir, Go, and Java. We also have examples of how to send emails using Vercel Edge Functions, Cloudflare Workers, Supabase Edge Functions, and other serverless solutions. What's our backstory? When I was a CPO at Liferay, I faced the problem of sending emails at scale. We had enterprise customers complaining about deliverability, and I've been frustrated with existing services ever since. More recently, as a VP of Developer Experience at WorkOS, I once again had to deal with emails landing in the spam folder. After looking at all the different solutions out there, I've been obsessed with the idea of solving this problem once and for all. We need to stop developing emails like it's 2010 and rethink how email can be done in 2023 and beyond. We believe that email development needs a revamp. A renovation. Modernized for the way we build apps today. That's why we're building Resend. What issues have you had with email sending? I would love to hear your ideas, experiences, and feedback on any and all of the above.

@zenorocha Can I write about Resend if you don't mind?

@zenorocha Congrats on the launch! We've been using Amazon for a while now but happy to check out your product. Out of curiosity: what do you see are some popular use cases for when html won't be enough for the email and you need react?

@zenorocha Congrats on the launch. Big fan of your work, both with Resend and prior to that. Resend makes email ridiculously easy for developers with its sleek interface, seamless integrations, and wealth of handy templates. Email, once notoriously hard to work with, is now React-TypeScript-enabled. A game-changer in simplifying the email developer experience. 🦄
Amit Arora
@zenorocha really interesting. any support for golang?
Ryan Hoover
I appreciate how much care Resend is putting into the details and entire user experience for developers. Gives me early Stripe vibes. What's been the biggest surprise or learning so far, @zenorocha?
Zeno Rocha
@rrhoover One thing I learned is that even though email is a pretty consolidated communication channel, it's still very hard to understand things like SPF, DKIM, DMARC, and BIMI. There’s a lot of hidden knowledge about email deliverability which is something you think would be solved for a technology that’s been around for 50 years now.

Impressive! Would be happy to try!
Zeno Rocha
@alex_dyadischev Please do and let me know how it goes!

Resend is a no brainer tool for any business. The team have built an amazing tool for developers, it just took couple of mins for me to setup & send first email to my customers.

I wish there is a resend email button on every email in email list. It could solve us in the following situations - end user deleted an email or didn't received it ?makers
Bu Kinoshita
@pradeeb28 That’s definitely something we want to add and it’s on the roadmap! Thanks for sharing
Yuhang Xia
Great product! We use Resend to power our emails in Zeabur and it's convinient and great! Congrats on the launch! Looking forward to a further collaboration :)
Zeno Rocha
@michaelyuhe Zeabur is awesome, we’re lucky to have you guys as customers!
Julien Zmiro
I haven't met any developer who likes setting up transactional email on an app. This is a super cool product, well done!
Zeno Rocha
@zmiro exactly, it should be that painful!
Han Wang
We use and LOVE Resend. Absolutely phenomenal product worth trying
Zeno Rocha
@han_wang6 thanks for the kind words Han!
Tristan Berguer
That's nice! I hope you will add marketing feature soon (with sequences). I will try for my next project 🚀
Zeno Rocha
@tberguer that's definitely in our radar ;)
Karsten Richter
Congrats on your launch and on raising the money for your next steps., Zeno. Your product sounds great. What I didn't understand on first sight is how you design emails inside Resend. What's the way you recommend?
Zeno Rocha
@karsten_picasi In terms of designing emails, we recommend using our open source project https://react.email which allows you to code a template using React, Tailwind, and TypeScript. Once you have a template, you can use the. native integration with Resend to send it.
Karsten Richter
@zenorocha What about importing templates from tools like BEE (https://beefree.io)?
Lucas Pilzen
UI is looking slick! 😍
Zeno Rocha
@lucas_pilzen glad you liked it! We definitely spend way too much time sweating all the details ;)
Amrutavarsh Kinagi
Switched to Resend after all the low-code/no-code options failed to deliver their promised simplicity. As a founder already tackling the myriad challenges with your product, emails are the last thing you'd want to struggle with. Resend is seamless, reliable and consistent, and we haven't had to look back on our emails since we first integrated them. Resend is a no-brainer because they understand the developer.
Marc Klingen
Congrats on the launch @zenorocha. Deeply impressed by the speed at which you and your team ships and how easy it is to use Resend across our stack. Thank you for building this!
Zeno Rocha
@marc_klingen thanks a lot for all your support Marc, really appreciate it
Felix Häberle
Congrats on the launch! ✨ I have followed Resend since day 1 on Twitter and have to say your process is amazing, I always found it hard to do email as a dev but with Resend, it feels much easier!! Keep up the good work 👍 Have you already thought about i18n features within Resend? We (inlang) are currently building an i18n solution for devs that could be useful if you want to offer content of any kind in multiple languages. You can join our Discord: https://discord.gg/XbaB6UwZXF if you want to know more.

Current go to email platforms like mailchimp or sendgrid are super outdated and complex, they mostly serve enterprises too. This could change the game and be something we use in our new products! Congrats on the launch 🚀
Naveed Rehman
Hey there! Just wanted to say kudos on the cool new product, Resend! It's great to see an email tool catered specifically for developers. I've been exploring it and already finding it quite handy. Any plans to expand its compatibility with different programming languages?
Bu Kinoshita
@naveed_rehman Which one do you know need support? You can find all our SDKs here https://resend.com/docs/sdks
