AutoSend is an email platform built for developers, marketers, and AI agents. It combines transactional email delivery with marketing campaign tools under one roof. You pay based on emails sent, not contacts stored. The platform offers a REST API with SDKs for Node, Python, PHP, Ruby, Go, and more, plus a drag-and-drop email builder for non-technical users. A built-in contact validation engine blocks spam traps and invalid addresses before sending. AutoSend also supports MCP integration, letting AI agents send emails directly as part of agentic workflows.

• Volume-Based Pricing: Pay only for emails you send, not the size of your contact list. Plans start at $1/month, scaling up based on sending volume rather than subscriber count.
• Developer-First API: Simple REST API with official SDKs for Node.js, Python, PHP, Ruby, Go, Rust, and more. SMTP support included for legacy systems.
• AI Agent & MCP Integration: Connect AI agents directly to email infrastructure through the MCP server. Let LLMs trigger transactional emails, manage campaigns, and check analytics from Claude, Cursor, or any MCP-compatible client.
• Built-In Contact Validation: A proprietary validation engine automatically identifies and suppresses risky addresses, spam traps, disposable emails, and invalid addresses before sending, protecting your sender reputation.
• Marketing Campaign Tools: Create, personalize, and send marketing emails with a drag-and-drop builder. Set up automated welcome sequences, onboarding flows, and re-engagement campaigns.
• Real-Time Analytics & Logs: Track opens, clicks, bounces, and unsubscribes in real time. Filter and search logs instantly to debug delivery issues.
• Easy Migration: Import templates, contacts, and automations from Resend, SendGrid, Loops, and other providers with zero downtime.
• Sender Authentication: Managed dedicated IPs for high-volume senders, plus full SPF, DKIM, and DMARC support built in.

• Transparent, Volume-Based Pricing: You're charged for emails sent, not contacts stored. This saves money as your list grows, unlike platforms that penalize you for having more subscribers.
• Strong Developer Experience: Well-documented API with SDKs in seven-plus languages, webhook support, and real-time logs make integration straightforward for engineering teams.
• Free Built-In Contact Validation: Every plan includes automatic email validation and suppression. No need to pay for a separate validation service to protect deliverability.
• Low Entry Barrier: The Hobby plan starts at just $1/month, making it accessible for side projects and early-stage builders without committing to expensive tiers.

• No Free Plan: AutoSend does not offer a free tier. Plans begin at $1 per month, meaning there is always a minor cost even for low-volume users.
• Shared IP for Lower Tiers: Dedicated IP addresses are available only for higher-volume senders upon request, which means smaller senders must use shared IP pools. This can make deliverability more dependent on the overall reputation of the pool.

• Transactional Email for SaaS Products: Send password resets, order confirmations, OTP codes, and account notifications through AutoSend's API. Built on Amazon SES, emails deliver within milliseconds, making it reliable for time-sensitive messages your users depend on.
• AI Agent Email Workflows: Connect your AI agent to AutoSend via the MCP server so it can draft and send emails as part of its decision flow. For example, an LLM-powered support agent can generate personalized responses and trigger email delivery without human intervention on the sending side.
• Startup Marketing Campaigns: Launch newsletters, product announcements, and promotional campaigns using the drag-and-drop builder. Volume-based pricing means you won't get punished as your subscriber list grows, keeping costs predictable for early-stage teams.
• Developer-Led Onboarding Sequences: Set up automated welcome sequences and onboarding flows that trigger based on user actions. Combine API-driven triggers with the visual automation builder to create personalized email journeys without manual effort.
• Migrating from Legacy Email Providers: Import existing templates, contacts, and automations from SendGrid, Resend, or Loops with zero downtime. The Resend adapter and multi-language SDKs make switching straightforward for engineering teams tired of overpaying.
