Where it sits in an outbound stack

Most outbound stacks are four layers: the data that decides who you talk to, the channel that carries the message, the writing that earns a reply, and the system of record that remembers what happened. Lead Onion sits in the marketing account intelligence software layer. Tools beside it are worth comparing on coverage and price; tools in the other layers are worth wiring to it rather than replacing it with.

Using Lead Onion with M for Mercury

Lead Onion covers a slice of go-to-market that sits next to outbound rather than inside it.

Where the two meet is usually the hand-off — Mercury pushes contacts and events out over webhooks, Zapier, Make, n8n or its own API, so a warm reply can trigger whatever Lead Onion is set up to do next.
