n8n is a powerful self-hosted automation option weβre exploring to support teams that want full control over how EmailGen AI runs within their stack.
We used HubSpot to organize ICPs and test how EmailGen AI fits into real sales workflows. It helped validate that our emails can plug into CRM sequences seamlessly.
We used Perplexity during development for deep research on outbound strategies, persona targeting, and spam compliance - much faster than traditional Googling.

OpenAIβs GPT-4 is the core engine behind EmailGen AI. Its natural tone and nuanced understanding of sales language helped us generate email copy that consistently performs.
We benchmarked against Claude to fine-tune prompt quality and variability. Its long-form structure helped us rethink how sequences should flow - even if itβs not our main model.
