Three prerequisites: a defined target list you can defend, a message that already works when a human sends it, and deliverability infrastructure. Automation scales an offer — it cannot create one. Automating a message that doesn't land just produces failure faster and burns the domain doing it.
Run the sequence as an invitation backed by proof in the prospect's exact shape and, where possible, a trigger-fired diagnostic rather than a generic pitch. Tooling choice follows the motion: dedicated deliverability platforms where volume is the constraint, LinkedIn-first tools where the channel is.
Every claim above comes from work LeanScale published. These are the sources.
