Maileroo

Maileroo is an email delivery platform for developers, startups, agencies, and growing businesses that need transactional and marketing email from one place. It combines SMTP relay, a REST API, delivery tracking, webhooks, and sending-domain management in a single workspace, reducing the need to stitch together separate email delivery tools.

The platform covers the full sending workflow, from programmatic delivery and verified domains to real-time logs, analytics, and inbound email routing. With separate streams for transactional and marketing traffic, dedicated IP options, and developer SDKs, Maileroo is designed for teams that need both reliable delivery infrastructure and visibility into what happens after an email is sent.

Built For Reliable Email Delivery

Maileroo is designed for teams that need transactional and marketing email without maintaining multiple disconnected systems.

It can be useful for:

• Developers integrating email into applications
• Startups building transactional email infrastructure
• Agencies managing email delivery for clients
• Growing businesses sending both transactional and marketing campaigns
• Engineering teams that need logs, APIs, and delivery events
• Teams handling sensitive data that need European data residency

Common Use Cases

Transactional Application Email

Send password resets, notifications, account messages, receipts, and other application-generated email through SMTP or the REST API.

Marketing Email

Use the same platform for marketing and bulk sending while keeping marketing traffic separated from transactional messages through streams.

Email Delivery Monitoring

Track delivery, opens, clicks, and bounces through real-time logs and analytics to understand how messages are performing.

Automated Email Workflows

Use API access and event webhooks to connect email delivery with applications, databases, customer systems, and internal automation.

Inbound Email Processing

Route incoming messages into your own workflows when applications need to receive and process email as well as send it.

Deliverability-Focused Infrastructure

Maileroo places deliverability at the center of its email infrastructure. It uses owned IP space, reputation controls, clean sending ranges, and sender vetting to help keep sending traffic separated from infrastructure associated with poor sending practices.

The platform also supports common email authentication and sending-hygiene mechanisms, including:

• SPF
• DKIM
• DMARC
• Suppression handling
• Sender vetting
• Reputation controls

This gives teams tools for managing both email delivery and the underlying sending reputation from the same environment.

European Data Residency

For teams working with sensitive or regulated information, Maileroo offers European data residency across Germany, the Netherlands, Finland, and France.

The platform is designed to support GDPR requirements while keeping email infrastructure and account controls in one workspace.

Team Permissions and Audit Logs

Maileroo includes granular permissions and audit logs for teams where multiple people need access to the email infrastructure.

• Granular account permissions
• Audit logs
• Shared team access
• Better visibility into account activity

These controls can be useful for agencies, engineering teams, and businesses where email infrastructure needs to be managed collaboratively.

Pricing

Maileroo includes a free monthly email allowance, with paid plans starting at $10.

This provides an entry point for teams that want to test the platform before moving to a paid sending plan as their email volume grows.

Why It Matters

Email delivery involves more than simply sending a message. Teams also need to manage domains, authentication, reputation, bounces, delivery events, inbound messages, and the infrastructure connecting email activity with their applications.

Maileroo brings these functions together through SMTP, an API, tracking, webhooks, streams, inbound routing, and deliverability controls. For teams sending both transactional and marketing email, this creates a single environment for sending, monitoring, and troubleshooting.
