  • I Built an Open-Source project. It Became the Official MailChannels JS SDK
    What started as a small Nuxt integration eventually became a full Node.js and TypeScript SDK for MailChannels. Along the way, I learned a lot from the Vue, Nuxt, and UnJS ecosystems, took inspiration from other developer-focused tools such as Resend, and eventually had the opportunity to join MailChannels and get the project adopted and officially maintained. - Source: dev.to / 1 day ago
  • Getting Your Writing Seen Beyond Your Own Site
    Two practical pieces. First, you need a transactional sender that can do broadcasts. I use Resend because the API is good, the React Email integration is good, and the dashboard is sane. Postmark and AWS SES work fine too. Second, on every publish, send a broadcast to your audience. This is the closest thing you have to a guaranteed reader. - Source: dev.to / about 2 months ago
  • How to Send Transactional Emails with Vue and Resend
    Resend has quickly become the default way to send email from modern applications. The API is clean, the deliverability is good, and the developer experience is impressive. But Resend only handles sending emails. It provides a html field and you produce the HTML that you've ensured is compatible with Gmail, Outlook, and the many other email clients. - Source: dev.to / 2 months ago
  • Adding comments to a static Astro blog with Netlify Forms
    Netlify/functions/comment-handler.js is triggered by a Netlify outgoing webhook Whenever a new submission hits the blog-comments queue. It sends an HTML email Via Resend (the same delivery layer used for new post notifications) containing the comment text and two HMAC-SHA256-signed action links:. - Source: dev.to / 3 months ago
  • How I migrated magic-link login from Resend to AWS SES + Lambda five days before launch
    I run toui.io, a URL shortener I shipped to the public on April 7, 2026. Eleven days before launch I had passwordless email login working on Resend. Five days before launch I tore it out and rebuilt the same flow on AWS โ€” Lambda + DynamoDB + SES + API Gateway, packaged as a SAM stack. - Source: dev.to / 3 months ago
