Top 10 new features in 2024
Zeno Rocha · 2024-12-31 · via Resend RSS Feed

Today marks the end of 2024. Before launching into 2025, let's recap some of the best features we launched this year.

Here's a quick overview:

  1. Broadcasts
  2. React Email 3.0
  3. Audiences
  4. Batch API
  5. New SDKs
  6. Email Scheduling
  7. Marketing Analytics
  8. Deliverability Insights
  9. New webhooks
  10. Platform Integrations

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 𝕏 (formerly Twitter).

2. React Email 3.0

This year, we launched two major versions of our open-source project React Email, which included numerous bug fixes, new features and components, and a 40x performance improvement.

Version 3.0, the latest version, included 54 components, along with several big performance improvements and new integrations.

3. Audiences

In January, we announced a new way to manage recipients.

Resend Audiences

Audiences let you add, update, retrieve, and remove contacts without having to worry about the entire unsubscribe flow. The new feature comes with 9 new API endpoints. We also introduced a CSV wizard for easily importing contacts.

4. Batch API

This year, we released a new batch API to send up to 100 emails in one request.

Batch Queue System Architecture

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.

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.

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

Broadcast Scheduling

Using broadcasts, you can use natural language to schedule emails to multiple contacts.

7. Marketing Analytics

To help marketing users understand deliverability, engagement, and when users opt-out, we released Marketing Analytics.

Marketing Analytics

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

8. Deliverability Insights

We often recommend the same best practices to our users and compiled these findings into Deliverability Insights, a new feature that provides best practices for email deliverability.

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.

Contact Webhooks

You can receive real-time notifications when contacts are created, updated, or deleted. These webhooks are helpful for sending welcome emails, storing contact updates, creating Slack alerts, syncing contacts with your CRM, and more.

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.

Zapier Integration

We launched a new Zapier integration that allows you to connect Resend with over 6,000+ apps.

We hope you enjoyed the new features we launched this year.
