March 2023 Summaries

The company recently launched seven new features in a period of seven days, known as Resend Launch Week. These features include support for three additional email sending regions, managed Dedicated IPs to improve IP reputation and deliverability rates, the integration of Webhooks for real-time notifications about email sending activities, a redesigned domain verification experience with reduced friction and DNS provider adaptation, Resend integrations with multiple platforms, email open and click tracking for actionable insights, and support for Tailwind CSS in React Email. This launch marks a significant milestone for the company, laying the foundation for future developments and shipments of new features.

Build beautiful emails with Tailwind CSS and React Email, a set of unstyled components that makes it easy to build modern-looking emails without dealing with old-school HTML and CSS. The integration is made possible by the team's hands-on support and the help of their open source community. A special thanks is given to Vinicius de Moraes for leading the initial implementation and fixing several issues along the way. The integration allows developers to customize the default theme with available properties in Tailwind CSS docs, making it a game-changer for email development.

Resend provides open and click tracking features that help users analyze engagement with their emails, allowing them to identify which customers are most interested in receiving messages. By enabling open tracking, Resend inserts a transparent GIF image at the bottom of each message, providing unique links that can be used to track opens by user. Click tracking enables redirects for links in the message, allowing users to determine which person clicked which link at what time. The feature is configured on the domain level and allows users to take action immediately, with options to integrate data points into external storage systems or provide a live pulse of their contact list.

The Resend team has announced the first batch of integrations, including Novu, Knock, Trigger.dev, and Pipedream, which enable developers to build customized drip campaigns, automate outage alerts, and notify customers about in-app activities with ease. These integrations provide a smoother development experience by eliminating the need to read through documentation to understand how two systems can work together. The new integrations offer features such as simple components and APIs for managing communication channels, flexible notifications infrastructure, API-driven workflows, code-level control, and no-code management of infrastructure. The Resend team is committed to exploring more integrations in the future and invites developers to reach out if they would like to build an integration with Resend.

With everything we build, we ask ourselves: “How can we reduce friction?” This philosophy guides our work on the redesigned domains experience with provider-specific instructions. Domains are crucial for sending email and now carry more emphasis than IP addresses in determining a sender's reputation. The new interface adapts to different DNS providers, such as Google Domains or Cloudflare, providing a tailored experience. Improvements include enhanced verification processes that impact deliverability, and streamlined onboarding for transactional email services like Resend. By reducing friction, we aim to make the process of setting up and managing domains more delightful.

Webhooks are a feature that allows one application to provide real-time information to other applications. With webhooks, users can receive notifications about email sending activities directly on their server, enabling them to automate workflows and track events such as opens, clicks, and bounces. Setting up webhooks is straightforward, requiring only the creation of an endpoint to receive POST requests and registration with Resend. The feature uses HTTPS and delivers a JSON payload containing metadata like event status, allowing users to take action in real-time.

We are excited to announce the launch of our Managed Dedicated IPs, offering high-volume senders more control over their sender reputation and improved deliverability rates. Dedicated IP addresses provide exclusive use for one domain, allowing full control over email sending activities and reducing the risk of emails going to spam due to someone else's actions. This leads to increased deliverability, improved sender reputation, and enhanced security. With our Managed Dedicated IP pools, we handle all the IP warming in the background, enabling users to immediately start sending at scale. While dedicated IPs are ideal for high-volume senders, any user can achieve incredible deliverability with our shared IPs, which often produce better results due to Resend's high-quality traffic. Our team provides white-glove support and aggressive measures to protect against spamming, bouncing, and malicious actors, ensuring the best possible email sending experience.

Resend has introduced support for multi-region email sending, allowing users to send transactional emails from three different regions: East US (North Virginia), South America, and another region TBD. This feature is designed to ensure timely and efficient delivery of emails regardless of the user's location. With this update, users can now choose which region their domains are set to, providing more flexibility in email sending. The new feature is expected to improve customer experience by reducing latency and increasing access to services. Resend emphasizes that its data residency policy remains unchanged, with all customer data still stored in the United States. The company invites customers to contact support if they require a specific region not currently supported.
