According to Live Direct Marketing's daily Tranco top-1M scan (July 12, 2026), Spaceship Mail is the mailbox provider for 158 domains — 0.02% of 658,108 domains with MX records. Detection method: primary MX record (lowest preference).
Spaceship Mail is an email mailbox provider that hosts incoming email accounts for domain owners. It is identified in email infrastructure by the MX records directing mail to its mail servers.
In the Tranco top-1M website dataset, Spaceship Mail appears most frequently on smaller sites within the .com namespace, with a geographic distribution weighted towards the United States. The consistent pairing of Spaceship Mail with Mailgun (a third-party transactional email service) across the data indicates that Spaceship-hosted domains typically outsource different email functions to separate providers. For senders, this footprint pattern means that Spaceship-hosted recipients are usually at smaller or independent operations rather than large enterprise or consumer email providers.

The regular co-occurrence of Spaceship Mail and Mailgun reflects how many smaller websites structure email operations: inbound mail is hosted on Spaceship, while transactional outbound mail (order confirmations, password resets, notifications) is routed through Mailgun. This separation of inbound and outbound functions is common in smaller or cost-conscious operations where unified email platforms are less practical. For senders evaluating their recipient base, this pattern indicates that sites using Spaceship for inbound mail have intentionally chosen a modular email architecture rather than an all-in-one service.
