For years, SendGrid was the default choice for transactional email. You signed up, verified your domain, integrated the API, and moved on. Its reliable infrastructure, extensive documentation, and widespread adoption made it the go-to platform for developers and businesses alike.
Then Resend arrived.
Launched in 2023 by the team behind React Email, Resend took a different approach. Instead of offering a feature-packed platform, it focused on developer experience. The API was refreshingly simple, onboarding took minutes, and the interface felt built for modern engineering teams rather than legacy enterprise software.
But great developer experience is only part of the equation. What matters most is whether your emails reach the inbox quickly and reliably.
In this comparison, we’ll break down how they compare—from setup and developer experience to deliverability, pricing, scalability, and which platform is the better fit for different use cases.
If you are open to a third option, ConvertNow publishes migration guides for teams coming from both SendGrid and Resend. It gives you an email API and SMTP relay for app email, plus campaigns, automations and segments for marketing, and it delivered 99.6% of emails over the last six months. Its AI email builder can also turn a short brief or an existing web page into a finished, on-brand email in seconds. It is free up to 10,000 emails a month.
