Maildoso mailboxes work with any tool that connects over standard SMTP/IMAP, plus a set of built-in integrations that make setup faster. Here's what's supported and how tracking works.
Sequencers and outreach tools
Maildoso mailboxes connect to all major cold-email sequencers. Built-in connectors and step-by-step guides exist for:
Instantly — see Connecting your mailboxes to Instantly.
Smartlead, Snovio, Email Bison, PlusVibe — see Troubleshooting sequencer connection errors.
Lemlist and other SMTP/IMAP tools — see Connecting your mailbox to Lemlist and other sequencers.
How you connect depends on the mailbox type: SMTP mailboxes are exported as a CSV of credentials (Email Accounts → select mailboxes → Export selected to CSV) and uploaded to the sequencer; Google Workspace mailboxes connect via the Google sign-in option or the dashboard's "Add to sequencer" button (Google mailboxes only). See How do I upload emails to my cold email tool?
CRM integrations
Direct CRM integrations are available for Front and Close. Other CRMs and helpdesks can use the mailboxes over IMAP/SMTP. For the current list, check the Integrations section of your dashboard.
API and MCP
Mailboxes and domains can also be managed programmatically — see Do you have an API or MCP server?
Tracking
Global Custom Tracking Domain (GCTD): open and click tracking is handled through Maildoso's global tracking domain, enabled by default on all accounts. You don't need to set up your own tracking domain. See What's a Global Custom Tracking Domain?
Per-account custom tracking domains (your own CNAME) aren't supported on Maildoso-managed DNS — see Custom DNS, nameservers, and tracking domains (managed DNS). If your sequencer asks for a tracking domain, see Where can I find custom domain tracking for my tool?
If you need tracking adjusted for your account, contact us.
