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. Sonnet sits in the conversation 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 Sonnet with M for Mercury
Sonnet is for the conversation once it exists. Mercury's job is the part before it: finding the right people, writing an opener that sounds like the person sending it, pacing every LinkedIn touch inside safe limits, and putting every reply in one inbox. A positive reply leaves Mercury as a booked conversation — which is where a tool like Sonnet takes over.
