Courier adds visual template designer with multi-channel preview on one canvas. Product events reach people on the channel they actually read, without building a sender for each one. Batching, throttling, delays, and conditions cover the notification-fatigue problem that most in-house implementations get wrong. Knock holds Category Leader here, and is worth weighing if that is closer to the problem Regal leaves open. ## Not a substitute for A buyer chooses between these and Regal rather than running both, so nothing here is paired across them. - **AI SDR Agents** (https://saastracker.org/categories/ai-sdr): AI SDR platforms run the research, list building, personalization, and sending steps of outbound prospecting autonomously, presenting themselves as a digital sales rep rather than a sequencing tool the user drives. - **Dialers & Business Phone** (https://saastracker.org/categories/sales-calling): Sales dialers and business phone systems give a team numbers, call routing, and outbound dialing modes, with CRM logging so every conversation is captured against a record. ## FAQ ### What is the best stack to run with Regal?
