December 2024 Summaries

This year, Resend.com launched several notable features to enhance its platform. The company expanded its capabilities by introducing a no-code tool for technical and non-technical team members to engage with their audience through the Resend API, enabling anyone to send email campaigns without code using broadcasts. Additionally, Resend.com released two major versions of its open-source project React Email, which included numerous bug fixes, new features, and components, resulting in a 40x performance improvement. The platform also introduced a new way to manage recipients through audiences, allowing users to add, update, retrieve, and remove contacts without worrying about the entire unsubscribe flow. Furthermore, Resend.com released a new batch API to send up to 100 emails in one request, a new Rust SDK for developers using the Rust programming language, and several new webhooks to provide more control and insight into events such as domain creation, updates, and deletions. The platform also introduced natural language scheduling to its API, allowing users to schedule emails at specific times without additional complexity, and released Marketing Analytics and Deliverability Insights to help marketing users understand deliverability, engagement, and opt-out rates. Lastly, Resend.com launched new integrations with Vercel and Zapier, enabling users to automate workflows and connect their platforms seamlessly.

We recently added a new component to Broadcasts, our no-code editor. The challenge was embedding dynamic media like Twitter posts into static emails while maintaining the email's integrity and usability. To solve this problem, we used three tools made by Vercel: `ImageResponse` constructor, `ImageResponse` to create images using JSX syntax, and Next.js response to capture rendering and return a JPG. We saved the rendered JPG in a static host (S3 bucket) and embedded it into the email HTML body as an anchor tag directed to the Twitter post. The solution involved several challenges, including sequencing issues with the `ImageResponse` constructor and limitations on CSS styles due to Satori library constraints. Despite these challenges, we were able to create a polished and visually appealing component that enables users to easily embed dynamic media into their emails.
