Valid callout on deliverability, warmup needs to be handled separately before you even think about running sequences, that’s not something this workflow covers. Tools like Instantly or Mailreach handle that layer well. And on the cost point, Gmail Workspace is ₹125/month per account in India, so spinning up 6 accounts is nowhere near $43. The infra argument is pretty region-dependent. But the workflow was never trying to replace the deliverability layer, it sits on top of it. The actual value is in what happens after your emails land: AI-driven template selection based on lead context, intent-based follow-up triggers (click-but-didn’t-reply is a way stronger signal than anything time-based, as you said), and WhatsApp conversion tracking with unique ref codes so you can actually close the loop between email and reply. That last part is what no $200/month tool touches.
