About

Maildoso provides outbound mailboxes built for cold email, combining SMTP and Google Workspace infrastructure, fast setup, strong deliverability, and automated technical configuration. It helps teams diversify their sending strategy with reputable mailboxes built specifically for cold outreach, so campaigns are not dependent on one sender type, domain, or provider. Users can register domains directly in the dashboard or connect their own, enter mailbox names, and have SPF, DKIM, and DMARC auto-configured so mailboxes are ready to export and use with outreach platforms in minutes. Maildoso supports SMTP mailboxes, Google Workspace mailboxes, and combined setups, giving teams flexibility based on their sending strategy and target audience. It connects with popular sequencers and outreach tools such as Instantly, Smartlead, Saleshandy, and others, making it easier to move newly created mailboxes into active campaigns.

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.
