Emitlo is a transactional email delivery service aimed at developers, providing both a REST API and an SMTP relay that share the same authentication, rate limits, and delivery observability. It's currently operating in private beta and positions itself as an infrastructure-grade alternative to established providers like Mailgun, SendGrid, and Postmark, emphasizing speed and low cost over feature sprawl.
The service handles the operational details of sending email reliably at scale — domain authentication, deliverability monitoring, and bounce handling — so engineering teams can integrate a few API calls or SMTP credentials rather than managing their own mail infrastructure or negotiating with a legacy ESP.
Emitlo automatically generates DKIM keys and publishes the required DNS records, with domain verification typically completing within about 60 seconds, removing one of the more tedious setup steps in email deliverability. Real-time webhooks (HMAC-signed) report every stage of an email's lifecycle — delivered, opened, clicked, bounced, or marked as spam — letting applications react to delivery events programmatically.
The company reports a 247ms median delivery latency and a 99.99% uptime SLA backed by redundant infrastructure, along with intelligent bounce handling and suppression list management to protect sender reputation. Both the API and SMTP relay support multiple sending domains and credentials per account.
Emitlo's Free plan currently offers 12,000 emails per month for early signups (up from a standard 2,000), capped at 400 emails per day and 50 per hour, with 3 sending domains, 14-day log retention, and full access to DKIM/SPF/DMARC, webhooks, and analytics.
The Pro tier is pay-as-you-go at $0.15 per 1,000 emails with no minimum commitment, supporting up to 500,000 emails per day, 20 sending domains, 50 credentials, and 90-day log history. Emitlo markets this rate as roughly 12 times cheaper than some alternatives and about a fifth of Mailgun's list price.
