About

Mailreef is a cold email mailbox infrastructure platform built by cold emailers to make delivery and scaling easy. Its mailboxes are designed to rival Google, Zoho, and Outlook while giving outreach teams a cold-email-friendly environment with dedicated mail servers, dedicated IP addresses, bring-your-own-domain support, and unlimited inboxes. It lets users create domains and mailboxes in one click, with SPF, DKIM, and DMARC automatically configured so teams do not have to manage DNS records manually. Mailreef is built for teams that need to scale cold email campaigns without wasting time creating accounts, setting up fake profiles, or dealing with mailbox blocks from traditional providers. Its infrastructure supports day-one campaign readiness through pre-warmed servers, pre-warmed domains, and pre-warmed mailboxes, helping teams start outreach faster while maintaining stronger deliverability foundations.

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.
