If you've started using AI agents for sales outreach, customer follow-ups, or internal operations, you've probably hit the same wall everyone hits: the agent needs to send email, but you don't want it using your inbox.
Molted is a service that gives each AI agent its own dedicated email address with a managed mailbox behind it. The agent can send and receive messages through an API, but everything passes through a layer of rules first — rate limits, cooldown periods between emails, suppression lists for people who shouldn't be contacted, and approval queues for anything high-risk like reaching out to a brand-new contact or mentioning a large deal.
The interesting part is the safety layer. Molted scans for prompt injection attacks — that's when someone sends your agent an email designed to trick it into doing something it shouldn't. It also blocks attempts to sneak sensitive data out through hidden links in messages. These protections are hard-coded, meaning the AI model itself can't override them even if someone tries to manipulate it.
On the practical side, there's a humanization feature that rewrites robot-sounding drafts into natural language before sending, outcome tracking that ties emails to actual business results like conversions or churn prevention, and journey orchestration for multi-step email sequences with branching logic.
Pricing starts at $9.99 a month for 3,000 emails. A growth plan at $39.99 adds unlimited mailboxes and the more advanced features. There's a 14-day free trial with everything unlocked.
The moment you let an AI agent send emails on behalf of your company, you're putting your reputation in its hands. One badly timed follow-up, one message to someone who asked to be left alone, one leaked piece of client data — and you've got a real problem.
Molted is built around the idea that agents need guardrails, not just access. If you're running automated outreach, onboarding sequences, or support workflows, this gives you a way to let the agent work independently while keeping a safety net underneath.
It works with email providers you might already use — Resend, Postmark, Amazon SES — so it sits on top of your existing setup rather than replacing it.

Prompt injection — A trick where someone hides instructions inside an email to manipulate your AI agent. Think of it like social engineering, but aimed at software instead of a person. Molted catches these before the agent can act on them.
Suppression list — A list of email addresses your agent is not allowed to contact. People who unsubscribed, competitors, or anyone you've decided should be off-limits.
Approval queue — Instead of sending certain emails automatically, the agent puts them in a queue for a human to review first. Useful for first-time contacts or sensitive topics.
