Guides, product updates, and thoughts on AI, email protocols, and browser automation.
Email infrastructure for AI agents is six distinct layers: inbox management, inbound processing, wait semantics, outbound sending, webhooks, and domain identity. Here's the complete picture.
The Model Context Protocol turns email from a destination into a tool Claude can call. Here's how to wire AgentMailr's MCP server into a Claude agent that reads, replies, and acts on email without human involvement.
The most valuable data is behind a login. Scrapers that only hit public pages miss most of it. Here's a complete implementation for creating verified accounts, saving sessions, and rotating identities at scale.
Almost every email-waiting loop for AI agents is the same: sleep, check, repeat. It works. It is also inefficient, slow, fragile, and completely unnecessary. Here's the better pattern.
SaaS tools, developer APIs, e-commerce platforms, content sites, job boards — almost all of it sits behind an email verification wall. Your agent can't get in. Here's the fix.
For production deployments, your agents should have addresses under your own domain. Here's how to set up custom domain email with MX, SPF, DKIM, and DMARC for AI agents.
Multi-agent failures from shared email are silent, intermittent, and hard to debug. A 20% failure rate with no error trace. The fix is inbox isolation — one inbox per task, by construction.
Testing signup flows is painful — parallel tests pick up each other's OTPs, temp mail services get blocked, and mocking doesn't test real delivery. Programmatic disposable inboxes solve this completely.
A complete seven-step pipeline for automated account registration with Playwright and AgentMailr — handling OTP codes, magic links, session persistence, and parallel scale.
CrewAI crews fail at email verification — they can research, plan, and execute, but can't receive an OTP. This guide adds AgentMailr email tools to any CrewAI agent in minutes.
LLMs, browser automation, code execution, vector search — all covered. But the ability to create an inbox on demand, use it for a task, and delete it? That primitive has been missing until now.
It takes 20 minutes to wire your Gmail to an agent. It takes two weeks for it to catastrophically fail — suspended account, flooded inbox, broken OAuth tokens, and OTP collisions.
LLMs, browser automation, code execution — all covered. But one infrastructure gap blocks agents from participating in the real internet: email. No one is talking about it.
Your agent can browse the web, fill forms, and click submit. Then it hits a wall: 'Please verify your email address.' With no inbox, the task fails silently. Here's the fix.
AgentMailr ships a native MCP server. Any MCP-compatible agent — Claude Desktop, Claude Code, Cursor — can provision inboxes, extract OTPs, and receive emails without any custom integration code.
LangChain agents break at email verification — they can fill the form but can't receive the OTP. This guide shows how to wrap AgentMailr as a native LangChain tool so your agents handle the full signup flow.
IMAP was designed for humans checking email once an hour, not for thousands of parallel agents each racing to receive an OTP within seconds. Here's why it fails and what replaces it.
IMAP polling loops are fragile, slow, and break at scale. Here's how to handle OTP verification in Playwright using AgentMailr's long-poll API — no regex, no retry logic, no collisions.
LLMs are evolving from chatbots into autonomous agents. But without a dedicated email identity, they're stuck using the developer's personal inbox — a security risk that collapses at scale.
