What is Keplars?

Keplars handles transactional and marketing email in one dashboard. Per the stored description, you can send through a REST API, SMTP relay, webhooks or SDKs, design broadcasts in a drag-and-drop editor, import Canva and Figma files as templates, warm up sending domains and track opens, clicks and bounces. The deal is a lifetime plan sold through RocketHub. The deal page could not be fetched.

What Keplars says it does

  • Send transactional email via REST API, SMTP relay, webhooks or SDKs
  • Drag-and-drop editor or hand-written HTML for broadcasts
  • Gradual domain warmup to build sender reputation
  • Real-time tracking of opens, clicks, bounces and deliveries

Why Keplars

It puts API email and campaign email under one login and one sender reputation, instead of two vendors. We could not check plan limits, volumes or terms because the deal page blocked access.
