Emailit Alternative
Compare Keplars and Emailit across APIs, SMTP, editors, automations, analytics and email infrastructure. Built for startups, SaaS products and growing teams.
Emailit covers the API and SMTP fundamentals for transactional and marketing email. As teams grow, they often need capabilities Emailit does not yet document or offer: official SDKs, a visual email editor, OAuth sending, and native automations and journey tooling.
Emailit's SDK documentation is still marked "Coming Soon," so most integrations go through the raw REST API. Keplars ships official SDKs across 11+ languages so your team can start building immediately.
Emailit manages templates through the API only, with no visual builder. Keplars gives you a drag-and-drop editor, a code editor, and Canva and Figma import in one unified tool.
Emailit offers event-based capabilities, while Keplars includes a full visual workflow builder and customer journey builder for lifecycle email out of the box.
