Cold email infrastructure launch checklist for agencies
Define a clear ready-to-launch standard
Track created, authenticated, connected, warmed, monitored, and reply-ready as visible operating states. This gives every team member a precise view of progress and turns client onboarding into a repeatable system.
1. Map clients to domains and owners
Record the client, dedicated domains, Google Admin owner, mailbox names, campaign owner, and renewal owner. ColdMail client workspaces keep these resources organized so teams can onboard, operate, and hand off every account with clarity.
2. Build the complete infrastructure budget
Combine the base subscription, mailbox count, domains, warmup, and sending software into one operating budget. ColdMail Starter includes ten mailboxes at $35 per month, and warmup for all ten adds $30 per month. Clear wallet and transaction visibility makes fleet costs easy to manage as the agency grows.
3. Provision mailbox batches at scale
Start with a representative batch, confirm mailbox names and domain assignments, and run an end-to-end send and reply test. Then expand the same proven structure across the complete client fleet with ColdMail’s bulk provisioning workflow.
4. Automate sequencer connections
Connect ColdMail infrastructure to sequencer tools such as Instantly and Smartlead, then confirm sending and reply synchronization. MCP, APIs, webhooks, and export-ready credentials give technical teams multiple ways to automate the workflow.
5. Centralize reply operations
ColdBox brings replies from connected mailboxes into one AI-labeled inbox. Assign owners for interested prospects, meetings, and follow-ups so the team can move every opportunity forward without switching between dozens of accounts.
6. Scale with provider-level visibility
Review warmup activity and health indicators across Gmail, Outlook, and Yahoo. Record each expansion and use provider-level trends to direct the next batch toward the strongest-performing infrastructure.
