Trust Center and SOC 2 Type II

Our SOC 2 Type II process has begun. Updates and related security content are published in our Trust Center, including the latest status of that assessment. We are also fully GDPR compliant with relevant information accessible in our Trust Center.

Public sector

Government in the United States

State and local government, public education, and contractors that need US data residency can send through Maileroo Enterprise with email content, attachments and delivery logs stored in the United States.

Maileroo is not FedRAMP authorised. Our security pack covers encryption, access controls and incident response, which is what reviewers ask about most. SOC 2 Type II is in progress in our Trust Center.

Enterprise capabilities

The features US teams use to send at scale

We are not just another email sending platform, we are a modern email delivery system that offers full control and flexibility over your email infrastructure. Control sending policies, restrict and route emails based on your business needs.

SMTP Relay & API

Send email through SMTP relay or the Email API with flexible options that fit the way your stack already works.

Dedicated IPs

Protect your sender reputation with dedicated IP addresses built for consistent, high-volume enterprise delivery.

Streams

Keep transactional and marketing traffic in separate streams so one channel never puts the other at risk.

Unlimited Domains

Connect every app and website you need on paid plans, with no hard limit on how many domains you can send from.

Isolated Sending Environments

Give each domain its own logs, analytics, and credentials so teams and brands stay fully separated.

Applications

Attach multiple domains to one vendor or service, then set outbound security rules that match your workflow.

Analytics & Reporting

Review up to 30 days of sending data and dig into the metrics that show how every campaign is performing.

Email Logs & Advanced Filtering

Search 14 days of email logs with advanced filters so you can find issues quickly and stay in control.

Email Resend

Resend failed, suppressed, or delayed messages from the dashboard for up to 14 days with a single click.

Suppression Handling

Automatically manage bad recipients, then import or export suppression lists whenever you need a closer look.

Click & Open Tracking

Measure opens and clicks across every send so you can see what engages people and improve the next campaign.

Custom Hostname Tracking

Use your own branded tracking domain on links to keep recipient trust high and your brand front and centre.

Return-Path

Set the return-path address that processes bounces and delivery updates so feedback loops stay accurate.

Blacklist Monitor

Watch your IPs and domains across major RBLs so reputation problems are spotted early, not after the damage.

Webhooks

Push delivery, bounce, and engagement events into your systems in real time so workflows can react instantly.

Inbound Routing

Route incoming email into your apps and workflows with inbound processing that fits how your team operates.

Templates

Build templates in the drag-and-drop editor, render them dynamically via API, and start from 200+ ready designs.

HTML Template Editor

Import HTML from a file, zip, or URL, then adjust the design visually without writing or debugging any code.

Collaborator Access

Invite teammates and assign permissions with fine-grained control over what each person can view or change.

SAML Sign-in

Configure passwordless SAML sign-in for your organization. Enables your organization greater security and compliance.

2FA

Add two-factor authentication with popular authenticator apps to keep account access locked down and secure.

Audit Logs

Track collaborator activity across your account so every important change is logged and easy to review.

Sandbox Environment

Test sending and integrations on a free domain before launch, so production stays clean while you experiment.

Domain API

Add and manage domains programmatically through the API so onboarding new sending domains stays automated.

Integrations

Connect with official SDKs in major languages, or plug into tools like Zapier, Make, and WordPress in minutes.

API Documentation

Follow clear documentation with practical examples so your team can integrate quickly and with confidence.

One-click Cloudflare Setup

"I love it as an SMTP service for transactional emails. The app is fast, easy to understand and fully featured, but not overwhelming, and email delivery is super fast and reliable. Just perfect! Every time I needed to request a feature or inquire about something with the team, they responded quickly and satisfactorily, both in their Discord channel and via email."

"I have been a Maileroo customer for almost 2 years now and I am very satisfied: Sending emails is super fast and reliable. The support is great and fast (usually within 1 hour). The interface is functional yet easy to use. You pay much less at Maileroo than at other providers without compromising on quality. In short, a great company to work with as an agency!"

"Using Maileroo for half a year now. Api and its documentation is simple, straightforward and just works. What truly makes the difference is the fast, personal support. Support is always quick to respond and to find a solution. Requests or suggestions are taken seriously and often translated into practical improvements. That level of personal involvement and service is rare and makes Maileroo a solution I can confidently recommend. Experience with mailgun, mailjet, sendgrid, resend and Maileroo takes the cake."
