Cold email and inbox glossary

The key terms behind cold outreach, reply management, and team inbox collaboration — in plain language.

Cold email
An unsolicited email sent to a prospect you have no prior relationship with, used to start a sales, partnership, or recruiting conversation. Sent at volume across multiple accounts to protect deliverability.
Unified inbox
A single shared view that aggregates email from many separate accounts. For outreach teams, it means every reply from every sending inbox appears in one place instead of behind separate logins.
Reply management
The operational work of reading, assigning, responding to, and closing replies that come back from outreach — distinct from sending the campaigns in the first place.
Sending account
An email account used to send cold outreach. Teams run many to spread volume and protect deliverability, which is why replies end up scattered across them.
Deliverability
The likelihood that a sent email reaches the recipient's inbox rather than spam. Spreading volume across many accounts and domains is a common way to protect it.
Thread assignment
Giving ownership of a specific conversation to one teammate, so it is clear who is responsible for replying and nothing falls through the cracks.
Internal note
A private comment left on a conversation that is visible only to your team, never to the prospect — used for context, deal stage, or next steps.
Thread status
A label on a conversation indicating where it stands — for example Open, Pending, or Closed — so a team can see what still needs action at a glance.
Shared inbox
An inbox multiple team members can view and work together, with visibility into who is handling what. The basis for collaborative reply management.
IMAP
A standard email protocol that lets an application access messages on a mail server. MyColdInbox uses IMAP to connect inboxes from providers beyond Gmail and Outlook.
OAuth
A secure authorization standard that lets you connect an account, like Gmail or Outlook, without sharing your password. Access can be revoked at any time.
Speed to lead
How quickly a team responds to an inbound reply. Faster responses to warm replies meaningfully improve the odds of booking a meeting or closing a deal.
