What It Is

Cleanbox is an email management SaaS positioned as an inbox governance tool to “stop email overload.” Through email aliases, contact rules, AI classification, filters, one-click unsubscribe, cloud storage for attachments, and custom-domain forwarding, it helps users clean up and route messages before they reach their real inbox. For users with their own domains, its Relay feature can also intercept spam, viruses, and blacklisted sources at the inbound layer by changing MX records.

Core Capabilities

Cleanbox offers a fairly complete feature set. Individual users can use aliases to hide their real email address and disable an alias with one click when it starts receiving spam. Filters can trigger actions such as blocking, forwarding, labeling, redirecting, and more based on sender, subject, body content, email headers, and AI classification. Attachments are automatically archived to the cloud by contact. At the team level, Cleanbox supports member invitations and fine-grained permissions for managing aliases, contacts, filters, and related resources. Developers can manage aliases, contacts, and messages via the REST API, making it suitable for automation and integrations.

Pricing and Trial

Cleanbox offers a free plan and a 7-day trial, both emphasizing that no credit card is required. The free plan is limited to 1 mailbox, 3 aliases, 50 emails per week, 5 filters, and a 7-day retention period. Paid plans range from Personal at $5/month to Enterprise at $100/month, scaling by number of mailboxes, aliases, email volume, filters, retention days, cloud storage, and custom domains. Relay inbound protection is only available on the Advanced and Enterprise plans.

Security and Compliance

Cleanbox processes full email content, including body text, headers, and attachments, and deletes it after 7 to 365 days depending on the plan. Its documentation states that emails and IMAP credentials are stored encrypted, that it does not sell data or show ads, and that it does not use email content to train third-party AI. On the Relay side, it uses Rspamd, ClamAV, Spamhaus/Barracuda/SpamCop DNSBL, and SPF/DKIM/DMARC mechanisms. However, the terms also state that it does not guarantee specific availability or successful email delivery, and we did not find SLA, ISO, SOC, or similar certification information.

Pros, Cons, and Best Fit

Cleanbox’s strengths are its quick onboarding, low barrier to entry with a free plan, and well-rounded feature set. It is especially suitable for individuals with high email volume, freelancers, developers, multi-domain managers, and small to midsize teams. Its drawbacks are the limited free-plan quota and the relatively high pricing threshold for the core Relay feature. If it is used for business-critical email flows, availability commitments, data compliance, and vendor maturity should be carefully evaluated.

Access from China

The collected information does not mention access from mainland China, a Chinese interface, local payment methods, or invoice support. Payments are handled through Stripe, and compatibility with domestic Chinese bank cards needs to be tested. If network access or cross-border payments are restricted, alternatives such as Gmail/Outlook built-in rules, enterprise email anti-spam gateways, Cloudflare Email Routing, SimpleLogin, and AnonAddy may be worth considering.
