Sentvia vs AgentMail
AgentMail email power, a fraction of the price.
Sentvia gives your agents real inboxes, two-way email, threading, and webhooks — everything you'd build on AgentMail — then hands you 10× the inboxes at a lower monthly price.
The same capabilities, priced for scale
Both give your agents real inboxes and full two-way email. The difference shows up on the invoice — especially when you need inboxes at volume.

Frequently asked questions
Does Sentvia do real two-way email like AgentMail?+
Yes. Email is our core. Agents get their own inboxes with full send and receive, native threading, replies, attachments, and real-time webhooks — the same workflows you'd build on AgentMail.
How much cheaper is Sentvia, really?+
At the entry paid tier, Sentvia gives 100 inboxes for $19/mo versus 10 inboxes for $20/mo. At scale, it's 1,500 inboxes for $99/mo. If you run many agents, the inbox cost difference compounds quickly.
Is migrating from AgentMail hard?+
No. Sentvia exposes a familiar REST API with Python and TypeScript SDKs plus an MCP server, so most teams swap their send and receive calls and keep their existing agent logic.
What about deliverability?+
Paid plans include custom domains with SPF, DKIM, and DMARC. Higher tiers add dedicated sending reputation and dedicated IPs for production-grade deliverability.
