What Enrich Layer is
Enrich Layer sits in the CRM enrichment APIs corner of the B2B go-to-market stack. In the vendor's own words: “Pull rich, verified data on people.” Put plainly, a tool in this category keeps CRM records current from an external data source.
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. Enrich Layer sits in the CRM enrichment APIs 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 Enrich Layer with M for Mercury
Enrich Layer is a data layer, and data is where LinkedIn outreach either works or wastes a sender. Mercury's Lead Finder searches 450M+ contacts and returns the LinkedIn profile to connect with alongside a verified work email, then enriches whatever is missing column by column. If Enrich Layer already holds your list, Mercury takes it from there: enrol the audience in a journey, spread it across senders, and pace every send inside safe limits.
