Every Tool You Need to Run Campaigns

From audience management to delivery analytics, everything in one dashboard. Not five different tools.

Audience Segmentation

Target the right subscribers with dynamic segments based on behavior, signup date, engagement level, or custom attributes.

AI-Powered Templates

Build send-ready campaigns in seconds using Launchpad with smart variable insertion, full HTML control, and live preview.

Campaign Scheduling

Set campaigns to go out at the perfect moment. Schedule by date, time, and timezone, available on all paid plans.

Contact Management

Import, organise, and manage your subscriber list. Handle unsubscribes and bounces automatically to protect your reputation.

Engagement Analytics

Track open rates, click-throughs, unsubscribes, and conversions for every campaign in real time.

Isolated from Transactional

Marketing and transactional traffic are completely separated. OTPs and critical emails always get priority routing.
