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. Day sits in the account management 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 Day with M for Mercury
Day is where the record lives, so what matters is whether outreach reaches it. Mercury syncs both ways — a reply, an acceptance or a stage change written in Mercury lands on the record, and a change made in the CRM comes back — with an origin flag on every row so an automated write is never mistaken for something a rep typed. Mercury connects to HubSpot, Salesforce, Zoho CRM and Attio directly, and to everything else through webhooks, Zapier, Make or n8n.
