1. Broadcasts

In January, we expanded Resend from being an email API only to a no-code tool for technical and non-technical team members to engage with their audience.

Broadcasts let you send email blasts using our WYSIWYG editor. It comes with email testing, markdown support, performance tracking, and 1,000 contacts for free.

We continued improving the editor, like our new style editor.

Additionally, we released four new components: Section, Code Block, YouTube, and 饾晱 (formerly Twitter).

The Batch API has full SDK support, including: Python, Ruby, PHP, Go, and Java.

5. New SDK

Rust has seen a rapid rise in popularity in the last few years, and one of the driving forces behind it has been the attention paid to type safety and developer ergonomics.

With those values in mind, this year we released our new Rust SDK. The new SDK joins a dozen other SDKs available for other languages, including Python, Ruby, PHP, Go, and Java.

New Rust SDK

You can now send emails with the official Resend SDK in your Rust projects.

6. Email Scheduling

We introduced two ways to schedule emails: transactional and broadcasts.

Transactional Schedule API

We introduced a new API to schedule transactional emails for a specific time.

import { Resend } from 'resend';


const resend = new Resend('re_123456789');


const oneMinuteFromNow = new Date(Date.now() + 1000 * 60).toISOString();


await resend.emails.send({
from: 'Acme <onboarding@resend.dev>',
to: ['delivered@resend.dev'],
subject: 'hello world',
html: '<p>it works!</p>',
scheduledAt: oneMinuteFromNow,
});

Later in the year, we also added natural language scheduling to the API.

Marketing Analytics provides aggregated metrics and itemized breakdowns of how your broadcasts performed.

Improve email deliverability by identifying issues and applying best practices.

9. New Webhooks

We introduced several new webhooks to provide more control and insight into events.

Domain Webhooks

Domains are critical to email deliverability. Some companies allow their users to configure emails in their own apps using custom domains, which is essential for deliverability, white-labeling, and branding purposes.

We added real-time notifications when domains are created, updated, or deleted to assist these users.

10. Platform Integrations

This year, we introduced several new platform integrations, including Vercel and Zapier.

Vercel Integration

We announced a new integration with Vercel, designed to speed up managing API keys and environment variables in your Vercel projects.

Now, you can integrate your Vercel projects directly within the Resend dashboard. With just a few clicks, create a new API key linked to the domain of your choice and have it instantly added as an environment variable in your Vercel project.
