Generic "Your payment failed" emails get ignored. LostChurn uses LLMs to generate recovery emails that match your brand voice, explain the specific issue in plain English, and tell customers exactly what to do. The result: 2-3x higher open rates and measurably more recovered revenue.

Sarah, quick fix needed for your Acme Pro plan
Hi Sarah,
Your $49/mo Acme Pro subscription payment on March 3rd didn't go through because your Visa ending in 4242 was declined by your bank (this usually means the card expired or hit a spending limit).
The fix takes 30 seconds: just update your card and we'll retry immediately.
[Update Payment Method]
Your Pro features (unlimited projects, priority support, and API access) will stay active for the next 5 days while we sort this out.

The AI includes the customer's name, specific plan details, decline reason in plain English, what features they'll lose, and a direct payment update link.
Three steps from failed payment to recovered revenue. The AI handles the hard part.
When a payment fails, LostChurn's LLM generates a personalized recovery email using the customer's name, amount owed, decline reason in plain English, and a direct payment update link. The AI uses one of 4 specialized prompt templates: recovery email, retry recommendation, customer risk assessment, or decline code explanation.
Review AI-generated emails before they go out, or enable auto-send for low-risk scenarios. Set approval rules by customer value, decline type, or campaign stage. High-value customers get manual review; routine soft declines go out automatically.
Customers receive an email that actually explains their issue and tells them exactly what to do. No more "Your payment failed" with a generic link. Recovery rates increase because customers understand the problem and trust the message.
Every feature is designed to maximize the chance a customer opens, reads, and acts on your recovery message.
Test subject lines, body copy, and send times with statistical significance. LostChurn auto-promotes the winning variant once confidence reaches 95%.
Emails land when customers are most likely to open them. We analyze timezone, past engagement patterns, and day-of-week signals to pick the optimal send window.
Start with email. If no response after 48 hours, escalate to SMS. Still nothing? Try WhatsApp. Each channel is configurable per campaign step.
Built-in email template editor with your brand colors, logo, and custom fonts. Edit directly or let the AI generate on-brand copy from your style guide.
Track open rates, click rates, and recovery attribution for every message. Know exactly which email in a sequence drove the payment update.
Not just one email. Build escalating sequences: friendly reminder on Day 1, urgency on Day 3, final notice on Day 7. Each step adapts tone automatically.
LostChurn's LLM engine (built on Gemini API) uses 4 specialized prompt templates to generate contextually relevant content for every scenario.
