Reviewers mostly see Resend as a simple, developer-first way to handle transactional email, with fast setup, clean APIs, good logs, and reliable deliverability showing up again and again. Users say it reduces the usual DNS, config, and maintenance hassle, and many pair it with React Email or modern serverless stacks. Makers of Refgrow and Rectify say they use it for onboarding, alerts, payouts, and support emails because it “just works.” Complaints are narrower: thin Python examples, missing unsubscribe or broadcast workflows, domain setup friction, and one report of severe sending delays.

Very easy to set up and to integrate with existing tools. It was easy to use resend as the default system for sending Auth & marketing emails. Very easy to make calls using Edge Functions in serverless environments.

Hi @zenorocha Congratulations to your launch. This really looks like something I will integrate in my apps. For me, observability is the main paintpoint when using other tools. In my opinion, a dashboard that visualises the logs would be a nice add-on. I would see bounce-rates, spam-rates, etc. immediately. When this information can be collected in a structured way, it could be very helpful for data-analysis, e.g. to see whether a combination of words triggers the likelihood of someone marking email as spam, etc. All the best for your launch, what I see now, I think it is a great product!

The best API for sending emails. Combine it with their OSS tools like React Email and you've got a winning combo. We've replaced Sendgrid with their service and have no regrets. Excited for the future to come!

Loving resend so far, tried both it's SMTP functionality and node client and 0 problems. I'll definitely be paying for this when I exceed the free email tier as I enjoy services like these that do one thing really well!

Resend revolutionized how we send emails by providing great APIs that abstract what developers have been manually doing for the past few decades.

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. However, it's tough to ignore them as they serve as a critical interface to connect with users. But we were lucky. We found Resend. It's 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.
