FAQ
Pricing FAQ
Is there a free plan?
Yes — Free is $0 forever with 1 domain, 1 mailbox, and full AI on hosted mail. Upgrade to a paid plan when you need more send volume, storage, or team features.
What counts as a mailbox vs alias?
A personal mailbox (e.g. peter@) has its own login and private inbox. A shared queue (e.g. support@) is a team address with its own mail store — teammates get access in Team and claim threads in Inbox; it is not a forward alias. An alias forwards to a mailbox (hello@ → peter@) and does not count toward your mailbox quota. Every plan includes up to 5 aliases per domain.
Why limit sends and storage instead of domains?
Startups need credible domain mail without nickel-and-diming addresses. Outbound volume and storage are where cost and abuse risk live — so those scale with paid tiers while domain and mailbox counts stay generous.
What are cloud AI tokens?
Cloud tokens measure OpenRouter usage for conversational drafts and agent workflows. Local summaries and triage don't count. Free includes 100k/mo; paid tiers include 1M–25M with overage at $2/100k (Business: $1.50/100k).
What happens if I hit my send limit?
Outbound mail queues until the next monthly reset or you upgrade. Inbound mail keeps arriving. We'll notify admins before you hit the cap.
How do I send from my app?
Use the HTTP API (POST api.unbox.im/v1/email) — domain keys in Domains → API. Optional SMTP is for legacy tools. Both paths are transactional mail only (receipts, alerts, password resets) — not newsletters or marketing bulk. Free and Starter are web-inbox only for send. See unbox.im/docs and our Terms for rate limits.
Should I use Apple Mail or Outlook for my Unbox inbox?
Prefer Unbox web for AI triage, shared queues, and team notes. Optional JMAP on Business works with clients like Twake Mail for phone sync — not Apple Mail/Outlook IMAP.
What are the send limits?
Team and Business include HTTP API + SMTP for transactional send only. Per-message caps (50 recipients), daily unique-recipient caps (1,000/workspace), and request rate limits (10/min/domain) apply in addition to your plan's monthly outbound quota. Marketing and bulk promotional mail are not permitted.
Can I upgrade as we grow?
Yes — upgrade anytime from Settings. Your domains, mailboxes, and DNS stay in place; higher tiers raise admin seats, storage, and monthly send volume.
Do you offer annual billing?
Yes — pay annually and save 20%. Contact us at hello@unbox.im to switch an existing account.
Can I send newsletters or marketing through the API?
No. Unbox API and SMTP are for transactional mail tied to a user action or system event — not newsletters, promotional campaigns, or cold outreach. Use a dedicated email marketing provider for bulk marketing.
Which mobile apps work with Unbox JMAP?
Twake Mail is the recommended JMAP client on iOS and Android. Ltt.rs also speaks JMAP. Use your mailbox address + app password at jmap.unbox.im (Business plan).
