We may render assistance with the Services account start-up if a corresponding timely request is submitted to the corresponding Support department.
You acknowledge that Spaceship may introduce general practices and limits toward use of the Service, including but not limited to the maximum number of days that email messages are retained by the Service, the email outgoing and incoming restrictions, the maximum size of an email message or file attachment that may be sent from or received by an account, the maximum disk space that will be allotted to You on Spaceship servers.

Each of Your email accounts is limited in its allocated resources (including but not limited to email and file storage) in accordance with the subscription plan.
You acknowledge and understand that Your account is limited in outgoing emails to the following number of emails:
Trial plans - 20 emails/hour per mailbox
Paid plans - 500 emails/hour per mailbox
Note: These limits apply per mailbox and include all aliases associated with that mailbox. Aliases share the same sending limits and do not increase the overall quota.
We may decrease this limit, at our sole discretion, should we suspect abuse and/or by queuing Your email messages internally, or by temporarily rejecting requests to send email through our services. Spaceship may block any message You attempt to submit using our services, for any reason whatsoever, with or without notifying You of such blocking. Under no circumstances will Spaceship be liable to You or any other party for any indirect, special, economic or consequential damages (including without limitation lost profits) arising out of email blocking or queuing.
In addition to hourly sending limits, Spaceship may, in its sole discretion, impose further restrictions on the volume and speed of outgoing email to ensure fair usage, protect the deliverability of messages, and preserve the reputation of our sending infrastructure. These safeguards may result in short delivery delays for large batches of outgoing email, particularly in cases of elevated sending activity.
While high send rates are permitted within plan limits, any attempt to send unsolicited bulk email, spam, or otherwise abusive traffic may trigger internal controls or enforcement measures, including rate limiting, deferral, or rejection of messages. These measures are designed to ensure reliable performance and equitable access for all users.
