Automatic List Hygiene

Email Design

Drag-and-Drop Email Builder

Easily create visually stunning emails with our intuitive drag-and-drop editor. Add text, images, buttons, and social media links without touching a line of code. Perfect for marketers who need professional-looking emails in minutes.

Upload or Import Designs

Already have an email campaign designed? Upload and import your existing email campaign from your computer and get started quickly.

Preheader Text

Add preheader text to control the preview line displayed in subscriber inboxes — on newsletters, autoresponders and saved templates alike. Optimized for consistent rendering across major email clients.

Previews

Confirm your emails look great before sending. Preview your message directly in your web browser or send a test email to yourself for final review across different devices and inboxes.

Advanced HTML Editing

For users who require full control over their email design, access the HTML source directly within the editor. Modify every aspect of your email’s layout and structure to match your exact specifications.

Analytics and Reporting

Real-Time Data

Monitor open rates, click-through rates, and other key metrics in real-time to assess campaign performance.

Custom Reports

Connect your Business Intelligence tool of choice to the on-premise database to generate detailed custom reports tailored to your needs.

Bot Detection

Automated link scanners and security bots can quietly inflate your open and click counts. Interspire tags robotic activity and filters it out of your reports by default, with a one-click toggle to compare filtered and raw numbers, tunable detection thresholds, and a robot column in every export.

Built-In Reporting

Access a range of built-in reports and graphs, providing essential insights without requiring third-party tools.

Privacy

For your subscribers and for you. Disable tracking if you prefer, and your data is stored securely on your own servers.¹

Security

Two-Factor Authentication (2FA)

Enhance account security by enabling 2FA, requiring users to provide two forms of identification before accessing the platform. Works with any RFC-6238 TOTP authenticator app.

Multi-User Access

Allow multiple team members to collaborate within the platform while maintaining secure access to email marketing campaigns.

Fine-Grained Permissions

Control user access with detailed p ermission settings, ensuring that team members can only access the specific features and data necessary for their role.

Encrypted Custom Fields

Store sensitive subscriber details with AES encryption at rest, field by field, so you protect only what needs protecting. Encrypted fields still support exact-match search and segmentation, and built-in safeguards keep protected values out of exports and merge tags.

Automatic IP Banning

Protect your account from unauthorized access with automatic login failure monitoring and IP banning.

Form Protection

Protect forms with Cloudflare Turnstile and honeypot spam protection to block bots without impacting real users.

Encrypted Database Connections

Connect to your MySQL database over TLS so subscriber data is encrypted in transit as well as at rest — useful when your database runs on a separate or managed host.

Scalability and Integration

API Access

Integrate with CRMs, e-commerce platforms, and custom applications using a comprehensive XML API. Search subscribers with exact, partial, and wildcard filters. Update custom fields for multiple subscribers in a single batch call. Build powerful integrations with minimal API overhead.

Webhooks

Send real-time notifications about list and subscriber activities, enabling dynamic interactions with your applications.

Multilingual Interface

Set the interface language per user, so international teams can share a single installation while each person works in the language they prefer. Additional languages can be added using standard language files.

High-Volume Sending

Queue and send over 100,000 emails per hour, accommodating the needs of growing businesses and large-scale campaigns. Or use our built-in speed limiter.

Large System Mode

Manage millions of contacts with consistent performance. Large System Mode uses cursor-based navigation instead of traditional pagination, reducing heavy database queries and keeping response times fast at any scale. Enable it with a simple configuration toggle.
