Lifecycle emails for modern SaaS products.
Turn user activity into timely lifecycle emails: welcome new signups, activate quiet users, recover churn risk, ask for feedback, and win back customers before they leave.
Sends through your own provider
From user behavior to timely lifecycle emails
Track users via API
Report signups, activity, metadata, purchases, subscriptions, and inactivity signals from your product.
Design flows visually
Build welcome, activation, renewal, feedback, discount, and win-back journeys on a visual canvas.
Understand every outcome
See which lifecycle moment triggered a flow, which branch a user took, and why a follow-up paused or stopped.
Use the email infrastructure you already trust
Connect the provider you're already sending with — in seconds. Your domain, your sender reputation, your deliverability. Driploop decides what to send and when; your provider does the delivery. No migration, no new vendor lock-in, no markup on volume.
Keep your reputation
Send from your verified domain — no warming up a new IP.
No migration
Paste an API key (or SMTP details) and you're live.
Switch anytime
Move providers without touching a single flow.
Works with
…or any SMTP server — Amazon SES, Gmail, Mailtrap, your own.
Visual flow builder
A React-Flow canvas with trigger, email, delay, condition, and action nodes. Build lifecycle journeys for onboarding, retention, renewal, feedback, and win-back without disturbing live runs.
API-first user tracking
Register users, record activity, update metadata, and log purchases or subscriptions through a clean, key-scoped REST API with idempotency and rate limiting.
Automation timeline & auditability
Every trigger, condition, branch, delay, render, skip, and send is recorded with a reason code and correlation id, so teams can trust what happened.
Reliable delivery, any provider
Bring Resend, Postmark, SendGrid, Mailgun, Brevo, or any SMTP server. Scheduled sends, duplicate prevention, retries, and full status tracking — on a SQLite-safe job queue.
