Show IH: One less thing to build: product emails in minutes.

Hi everyone, I am Deb Singha - Founder of Keplars. My co-founder and I were building an MVP for a bigger product idea. All we needed was to send a few transactional emails so users could sign up and test the product. Simple, right? Instead, we accidentally became email infrastructure engineers. Everywhere setup was so complex and time taking that our focus shifted from building the product to fixing email, and the MVP got delayed.

So we came up with keplars.com - it's a developer-first transactional email platform where you can send emails under 5 clicks unlike other platforms where setup takes hours to even days.

Our Keplars v2 is launched and custom domain feature is absolutely ready with a truly flexible pricing plans.

Would love to give features list in details:

  1. OAuth Email domains - just connect Google workspace/Gmail/Microsoft Outlook and create API key/SMTP/Webhooks and start sending emails. No domain setup headaches.
  2. Custom domain with TXT, DMARC, DKIM
  3. Drag and drop email template builder (No-code email template builder with preview in mobile, desktop screens)
  4. AI-Generated email templates
  5. HTML markdown email code editor
  6. Email scheduler, Team invitation
  7. Integrations with Supabase, Firebase, Vercel and more coming along.
  8. Check out our exclusive dynamic pricing plans: https://keplars.com/pricing

Do try it out in your projects and any feedbacks are appreciated. We also have partner programs. Thanks.

    love that you turned that frustration into a dev-first low-friction solution instead of just accepting the complexity.

    Nice! Product emails are always a pain to set up.

    What was your biggest challenge during the build? (I'm non-technical, always curious how others approach it)

      Thank you. Just focusing on the UX, how to make it absolutely easy for developers so that email doesn't give them a headache. Do signup and give it a try.

    Hey — quick note.
    I run Signal48. I help founders spot real user pain points and missed opportunities by scanning Reddit, reviews, and online communities — delivered in 48 hours.
    I took a quick look at your product and noticed a few recurring patterns users mention.
    Would you be open to a short insight report? No pressure — just thought it might help.
