The platform offers a clean drag-and-drop editor for designing beautiful emails, real automation so you can set up welcome sequences and behaviour-triggered campaigns even on lower tiers, and tools like landing pages, signup forms, and pop-ups to grow your list. It includes segmentation to target the right subscribers, A/B testing to improve results, and clear reporting to understand performance.

What is Whisperr?
Every retention tool needed someone to operate it. Whisperr is built to do the work itself.
Whisperr continuously monitors customer behavior, detects churn risk and engagement drops, decides the right intervention, writes the message in the brand's voice, selects the best channel, sends it, and learns from the outcome. The full loop can run in under 10 seconds.
Teams can start in Approval Mode, where every intervention can be reviewed before sending, then gradually move toward greater autonomy. Whisperr supports email, SMS, push notifications, in-app messaging, and WhatsApp.
Built for subscription businesses and DTC brands, Whisperr helps teams run sophisticated retention without manually building and operating every lifecycle workflow. Integration is designed to take less than 30 minutes.
What problem it solves
Retention work is often too slow and too manual. Teams have to notice disengagement, identify the right users, decide what to do, write the message, choose a channel, and launch the intervention before the opportunity to save the customer disappears. Whisperr automates that process, helping subscription businesses act on churn signals in seconds instead of days.
Alternatives & competitors
Whisperr is an autonomous alternative to retention and customer engagement platforms such as Braze, Iterable, Klaviyo, and Customer.io. Unlike traditional tools that still require a team to build audiences, write campaigns, choose channels, and operate workflows, Whisperr is designed to run the retention process itself while keeping teams in control through Approval Mode.
Pricing
Paid plans from $299/month. Growth is $899/month, Scale is $2,499/month, and Enterprise is $4,999/month.
