You don't need enterprise email for a weekend build.
Most email platforms are built for companies, not for the project you're shipping tonight.
- Buy a domain before sending anything
- Configure SPF, DKIM, DMARC
- Sign an annual contract
- Seat-based pricing
- Sales calls just to get a quote
- Onboarding that takes longer than the project
With Keplars, connect Gmail or Outlook with OAuth and start sending immediately. The free plan covers most side projects outright.
From git init to first email in minutes.
