MyAgentMail vs Resend:
Outreach Infrastructure vs Transactional Email
Resend is excellent at what it does: sending transactional emails from your app with a clean developer API. But when your AI agent needs to send outreach, receive replies on the same thread, run follow-up cadences, reach contacts on LinkedIn, and isolate each customer's identity — Resend's scope ends. Here's the honest breakdown.
Two different jobs
Resend is a transactional email API. It handles one direction of communication: your app sends, the user receives. Beautifully simple. Purpose-built for welcome emails, receipts, alerts, and password resets.
MyAgentMail is outreach infrastructure. It handles the full loop: agent sends, prospect replies, agent gets notified, cadence continues. It adds LinkedIn as a second channel on the same API key. It isolates each customer's sending identity if you're building multi-tenant. These are different tools for different jobs.

Frequently Asked Questions
What is Resend and what does it do?
Resend (resend.com) is a developer-focused email API built for sending transactional emails from web and mobile applications. It supports React Email templating, custom domains, and email analytics. It is not designed for outreach, reply handling, LinkedIn, or multi-tenant agent infrastructure.
Can I use Resend for AI agent outreach?
Technically you can send outbound emails through Resend's API from an agent. But you'd need to build separate infrastructure for: receiving replies (IMAP listener or a third service), threading replies back to the original send, pausing sends when bounce rates spike, LinkedIn outreach, and per-customer isolation if you're shipping multi-tenant. MyAgentMail handles all of this out of the box.
How much does MyAgentMail cost vs Resend?
MyAgentMail's email-only Starter plan is $5/month for 2 inboxes and 6,000 emails. Resend is free up to 3,000 emails/month and $20/month for 50,000 emails. For pure sending volume, Resend is cheaper. For the full outreach stack (replies, cadences, LinkedIn), MyAgentMail is cheaper than assembling the equivalent from multiple services.
Does MyAgentMail have a free tier?
MyAgentMail does not have a free tier, but the Starter email plan at $5/month is low enough to start. LinkedIn access starts at $29/month for the Solo plan. There is no long-term free tier because the infrastructure (SMTP relay, IMAP, bounce monitoring, LinkedIn session management) has real operating cost.
Do I need to choose between MyAgentMail and Resend?
Not necessarily. They serve different jobs. A common pattern for agent builders: use Resend for app-triggered transactional emails (user onboarding, receipts), and use MyAgentMail for outreach flows that require reply handling, cadences, and LinkedIn. The npm packages can coexist in the same codebase.
Need the full outreach stack for your agent?
Email + LinkedIn on one API. Replies as webhooks. Cadences with auto-exit. Multi-tenant workspaces. npm install and ship in a day.
