Build products. Not email infrastructure.
Don't waste your weekend configuring SMTP servers, DNS records, and email authentication. With Keplars, start sending emails in minutes using Gmail or Outlook with OAuth, then switch to your own domain whenever you're ready.
Launch faster. Stay focused. Ship more.
Built for people who ship.
You don't have a DevOps team. You don't have an email engineer. You probably don't even have a support team yet. You just want to send:
...without spending days on infrastructure. That's exactly why we built Keplars.
Your weekend shouldn't end with DNS errors.
Most email providers expect you to:
- Buy a domain
- Configure SPF
- Configure DKIM
- Configure DMARC
- Generate SMTP credentials
- Verify everything
- Debug why emails aren't sending
By the time you're done, you've forgotten what feature you were actually building.
Keplars lets you start with OAuth Email Sending using Gmail or Outlook. No custom domains. No DNS configuration. No SMTP setup. Just connect, build, and ship.
Start simple. Scale whenever you're ready.
Your first customer doesn't care how your email infrastructure works. They only care that:
Start with OAuth. When your product grows, verify your own domain and continue using the exact same API. No migration. No rebuilding. No surprises.
One platform instead of five.
Most indie makers end up paying for an email API, a marketing platform, a template builder, analytics, and automation. Keplars combines everything into one simple platform.
