AutoSend
Freemium
AutoSend is an email platform for transactional and marketing messages with API, SMTP, SDK, webhooks, and automation for developers, marketers, and AI-agent workflows. Billing is based on email volume, not contacts.
What is AutoSend?
AutoSend is an email platform for developers and marketers that combines transactional email, marketing campaigns, and automation in one product. The site describes it as a lightweight SendGrid alternative and emphasizes pricing by sending volume rather than by contacts.
For transactional use, AutoSend offers a REST API, SMTP access, SDKs, webhooks, and delivery logs for events such as delivery, open, bounce, and failure. For marketing workflows, it supports campaigns, templates, contacts, segmentation, domain warmup, and automation, with additional documentation and MCP-based tools for AI agents.
What can AutoSend do?
SMTP support
Connect through SMTP when you want to use AutoSend with an app or platform that already speaks SMTP, without changing your sending workflow.
SDKs and code examples
Use SDKs for common languages and frameworks, including Node.js and Next.js examples shown on the site, to reduce setup time.
Marketing tools
Create campaigns, build templates, manage contacts, and run automation for marketing email workflows in the same product.
Delivery monitoring and analytics
Track delivery, open, click, bounce, and failure events with logs and analytics shown on the transactional and pricing pages.
Agent workflows
Use MCP, skills files, and agent-oriented docs so AI agents can operate email tasks from natural language prompts.
Use Cases
“Transactional product email”
Use AutoSend for OTPs, password resets, and product alerts when you need programmatic delivery and event-level visibility into sends, opens, bounces, and failures.
“Marketing campaigns”
Create newsletters, launches, and other audience-facing campaigns with templates, contacts, segmentation, and campaign analytics.
“Email automation”
Set up welcome sequences, onboarding flows, and re-engagement emails that run automatically based on triggers or user activity.
“Agent-operated email workflows”
Connect an AI assistant or coding agent to manage email tasks through MCP or skills-based docs instead of switching back and forth with the dashboard.
“Volume-based email operations”
Use the platform’s pricing model when you want email costs tied to sending volume rather than growing contact lists.
