ChatGPT plugin

Cold email diagnostics

View in ChatGPT directory

Deliverability AI WarmInboxes is a read-only cold email diagnostic and operator assistant powered by the WarmInboxes MCP. It combines live domain, DNS, authentication, reputation, bounce, tracking and list checks with WarmInboxes' continuously updated knowledge base of operator playbooks, diagnostic recipes, first-party research and infrastructure planning tools. It helps diagnose sudden reply-rate drops, spam placement, bounce spikes, domain health, campaign or list problems, provider routing and sending capacity, then recommends what to fix, rest, test, resize or replace. It can also clean and segment lead CSVs, analyze cold email copy, and plan Google Workspace, Microsoft 365 and Azure sending infrastructure. No API key or login is required. It does not send email, change DNS, make purchases or guarantee inbox placement.

Deliverability AI WarmInboxes is #10,527 of 13,927 ChatGPT plugins by placement, up 129 places in a week.
