Molted Email

Agent mailboxes with dedupe, cooldown, consent and injection-scanning enforced at the infrastructure layer

freemiumFour tiers, with the full platform on every one — Agent Runtime API, journey orchestration, outcome attribution, deliverability monitoring, operator console and multi-provider failover — so plans differ only on volume. Free is $0 with no credit card: 100 emails a month, 50 a day, 20 an hour, 1 mailbox and 100 MB storage. Starter is $9.99/mo with a 14-day free trial: 3,000 a month, 500 a day, 100 an hour, 3 mailboxes, 3 custom domains and 3 GB storage. Growth is $39.99/mo with a 14-day free trial: 10,000 a month, 1,000 a day, 200 an hour, 10 mailboxes, 10 custom domains, 10 GB storage and the Humanizer in beta. Enterprise is custom-priced with unlimited volume, mailboxes, domains and storage, a 99.95% uptime SLA, a dedicated support channel and custom limits. Limits cover total sent and received volume. Exceeding a limit returns a rate-limit error with no overage charge; upgrades take effect immediately and downgrades at the next cycle.View full pricing →

About Molted Email

Molted Email is agent email with policy enforcement in the infrastructure rather than in the prompt, which is a direct answer to the failure mode its own testimonials describe: nothing ordinarily stops an autonomous agent from spamming your users. Every send is checked before it leaves — duplicate prevention on a dedupe key, cooldown windows, suppression lists, consent validation and rate limits — and inbound replies are scanned, including for prompt-injection attacks aimed at the agent reading them. Threads are tracked and classified by intent so the agent knows what it is answering. Around that sit journey orchestration, outcome attribution, deliverability monitoring and an operator console, all included on every tier including free; only volume changes between plans. Delivery routes across Amazon SES, Postmark and Resend with automatic failover to whichever provider is healthiest. Setup is a global CLI install and a signup command that returns a mailbox and API key, with SSE event streaming and magic-link generation for user sign-in flows. A Humanizer on the higher tiers rewrites AI-drafted mail in a chosen style and stores both versions so the change is auditable. Exceeding a limit returns a rate-limit error rather than an overage charge. Magic-link generation for user sign-in flows is a single command, and the operator console gives a human view over what the agents have been sending, which is the piece that makes the guardrails auditable rather than merely present.
