The Cold Outreach Stack
This is the classic outbound pipeline. Start by finding your ICP in a massive B2B database, verify their email addresses so nothing bounces, then launch a multi-step cold email sequence with inbox warmup built in. Every step feeds the next — no manual CSV uploads, no guessing.
