Who it's for

Developers, SaaS founders, and technical teams who need to send transactional email (notifications, receipts, alerts, one-off and bulk system messages) from their own applications without operating their own mail servers.

What you get

A REST API (v4) and SMTP relay for sending transactional messages, official client libraries for languages including Python, PHP, C#, JavaScript, Ruby, and Go, email templates with a drag-and-drop designer, webhook notifications for send/open/click/bounce events, inbound email routing, suppression and bounce-list management, and email logs with delivery status. Deliverability tooling covers SPF/DKIM/DMARC setup guidance and DNS validation, and dedicated IPs are available as a paid add-on, including an EU-hosted option for data residency.

How it works

An account is created via a web dashboard, where API keys or SMTP credentials are generated; applications then call the REST API or connect over SMTP to send messages through Elastic Email's own in-house mail transfer agent. Delivery status, suppression handling, and event webhooks run through the same account, with a free plan (3,000 emails/month) and paid Starter/Pro plans priced by monthly send volume.
