Sidemail – Email platform for SaaS (email API, newsletters, automation)

Hacker News

Hi all! I'm Kristyna, maker of Sidemail. I'd love to share with you what we've been building. We built Sidemail because sending emails from a SaaS app was way harder than it should be. Sidemail is made for developers and teams that want one simple place to handle SaaS emails with reliable delivery and no bloat. It has: - Everything for creating, managing and delivering SaaS emails in one platform, - Easy-to-use email API for sending password resets, receipts, etc. - Messenger for writing product updates and newsletters, - Email automations for onboarding and lifecycle flows, - Fast email delivery and reliable infrastructure, - Developer-focused features like detailed API logs, Markdown emails, simple domain verification and DKIM, and more. - No-code editor and premade email templates tested across all major inbox providers and devices. The whole integration process takes less than 30 minutes. If you want to try it out, there is a free trial. Quickstart docs here: https://sidemail.io/docs/email-sending-quickstart/ If you have any questions or thoughts to share, please do tell! We’re happy to improve further. Thanks! Kristyna
