About

MyColdInbox is a web-based shared inbox and email management platform for teams handling cold-outreach replies across multiple sending accounts. It connects Gmail and Google Workspace, Outlook and Microsoft 365, and compatible IMAP/SMTP mailboxes, bringing incoming messages into a unified workspace with each message linked to its source mailbox. Teams can filter and search conversations, label replies, assign threads to teammates, add internal notes, and reply from the original sending account. Role-based workspaces support agencies managing client inboxes, as well as sales development, lead-generation, recruiting, and founder-led outreach teams. MyColdInbox manages replies rather than sending campaigns, allowing teams to keep using their existing campaign tools. It also includes thread status tracking and shared or personal inbox visibility settings.

About

PureBox is a Gmail inbox-cleanup service that helps users organize crowded mailboxes while retaining control. After connecting through Google OAuth, it analyzes sender and message patterns, including engagement signals, and groups email into Inbox, Archive, and Trash suggestions with plain-language reasons. Users review and approve messages or batches before cleanup; Pro can optionally automate trusted patterns. Approved archive, label, and trash actions run in Gmail. Pro adds recurring scans and RFC 8058 one-click bulk unsubscribe requests, with up to 50 requests per day. A hosted Remote MCP server lets compatible AI assistants check scan status and suggestions and prepare guarded cleanup plans. PureBox is for Gmail users such as founders, freelancers, consultants, and professionals managing newsletters, promotions, receipts, and inbox backlogs. A one-time free sample scan previews up to 100 emails from a limited sender sample; paid plans add broader and ongoing coverage.
