Multibox Email
Unlimited inboxes.
Zero limitations.
Multibox lets you create, send, and reply across identities all from one dashboard.
Truly Unlimited
Create as many sender identities as you want, no hidden caps, no tiered pricing. If you own the domain, you own the inbox.
Secure by Default
Built with strict authentication and domain-level validation. Every message you send is backed by SPF, DKIM, and clean headers.
Works With Everything
Multibox plays nice with whatever setup you’ve got, client work, burner addresses, SaaS alerts, or full transactional flows.
Instant Setup
Connect your domain and start sending in minutes. No DNS headaches, no SMTP struggles, no waiting for approval.
