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. 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 → Export accounts → Download all accounts as CSV (or Download selected accounts as CSV) — and uploaded to the sequencer. This works with any tool.
Google Workspace mailboxes are sent to the sequencer directly from the dashboard: connect the tool once under Settings → Sequencers for GW (Plusvibe, Emailbison, Instantly, ReachInbox, Warmy.io, Manyreach and Smartlead are available), then use Email accounts → Export accounts → Add selected Google accounts to Sequencer.
CRM integrations
Open Integrations in the left menu (the page is titled CRM). Direct integrations are available for Front and Close — each card has a How it works link explaining the integration and a Connect button to set it up. Other CRMs and helpdesks can use the mailboxes over IMAP/SMTP.
API and MCP
Mailboxes and domains can also be managed programmatically — see Do you have an API or MCP server?
Tracking
Global Custom Domain Tracking: open and click tracking is handled through Maildoso's global tracking domain, enabled by default on all accounts (the toggle is under Settings → General). You don't need to set up your own tracking domain, and if your sequencer asks for one, the same article explains what to enter. See Global Custom Domain Tracking (GCDT).
Per-account custom tracking domains (your own CNAME) aren't supported on Maildoso-managed DNS — see How DNS works on your Maildoso domains.
