Email platform FAQ

Questions teams ask before moving their email

Straight answers about private inboxes, transactional sending, pricing, and operating Super Mail Hub in production.

Can Super Mail Hub host private business mailboxes?

Yes. Create mailboxes on verified custom domains, connect securely through IMAP and SMTP, and manage storage and access from the same workspace as product email.

Can developers send through both SMTP and an email API?

Yes. Every plan includes SMTP relay and the REST API. Use scoped API keys for applications and SMTP credentials for tools that do not support an API.

Is the Free plan time-limited?

No. The Free plan remains available within its published limits. Paid plans are handled through secure Paddle checkout.

Do longer billing terms cost less?

Yes. Eligible paid plans save 10% with annual billing, 18% with a two-year term, and 25% with a three-year term. Checkout shows the full prepaid total and renewal date before payment.

Can I get a refund if I change my mind?

A first annual or multi-year purchase can be canceled for a full change-of-mind refund within 14 days, provided the workspace has not materially used the service. Monthly charges and renewals are normally non-refundable, except where law requires otherwise or the service was materially unavailable.

How does Super Mail Hub handle sending spikes?

Accepted messages are stored in a durable queue and processed by concurrent workers. Rolling hourly limits range from 50/hour on Free to 1,000/hour on Business. New Free accounts activate progressively, while bounce and complaint monitoring automatically protects platform reputation.

Can an administrator change features for one customer?

Yes. Administrators can assign plans, suspend or block an account, and allow, remove, or override individual features and limits for any customer.
