SentFromAI

Overview

SentFromAI, operated by Brightboard AI Ltd in the United Kingdom, builds communication infrastructure for AI agents. Its live product gives each agent its own email inbox through a REST API and an MCP server. SMS numbers and iMessage are in early access: the SentFromAI team sets them up on request rather than through self-serve signup, and both use the same inbox, threading and webhook model as email.

Key features

• Email: an inbox per agent with send, reply, forward, threads, drafts, labels and custom domains
• iMessage (early access): blue-bubble delivery with read receipts, typing indicators and SMS fallback, according to the product page
• SMS (early access): a phone number per agent with two-way texting
• Webhooks signed with HMAC-SHA256, plus a live WebSocket event stream
• MCP server with 21 email tools, as an MIT-licensed npm package or a hosted endpoint with OAuth sign-in
• Docs recipes for LangChain, OpenAI Agents SDK, Vercel AI SDK, CrewAI, LlamaIndex and OpenClaw
• Agents can create their own account; a human claims it to enable sending
• Email data hosted in Ireland on every plan

Pricing

Email plans are published: Free ($0, 5 inboxes and 5,000 emails a month), Pro ($19 a month, 100 inboxes), Scale ($99 a month, 1,500 inboxes) and Business ($299 a month, 15,000 inboxes). Paid plans bill overage per 1,000 emails. Enterprise adds dedicated IPs, an SLA and SSO. SMS and iMessage pricing is shared through sales only.

How it compares to Linq

Linq's iMessage API is generally available, with group chats, tapbacks, effects, polls and RCS fallback documented. SentFromAI's iMessage is in early access, and its public pages list only blue-bubble delivery, read and typing signals and SMS fallback. SentFromAI offers email inboxes for agents, which Linq does not. Linq publishes messaging prices, with Pro from $260 a month; SentFromAI does not publish messaging prices.

Best for

Teams whose agents need email inboxes today and want SMS and iMessage from the same provider once early access opens to them.
