Before buying
The stack only works if the workflow is clear before the next subscription gets added.
- Start with the bottleneck this fractional sdr stack is meant to solve before adding another tool.
- Keep source data, outreach execution, and reply ownership separate enough that weak layers can be swapped.
- Review the stack after the first campaign cycle and remove any tool that does not change list quality, reply rate, or follow-up speed.
