Customer Retention Timeline
Every sequence runs fully automatically once Cafe24 is connected.
Customers disappear after their first order
You never follow up after checkout, so hard-won customers rarely come back.
Automated 7 / 14 / 30-day retention sequences
Reviews never build up
You miss the right moment to ask, so products stay under-reviewed and new buyers hesitate.
Auto-sent at the ideal moment — 3 and 7 days after delivery
Manual work eats your time
You're exporting CSVs and re-uploading them into another tool, every single day.
One Cafe24 connection, fully automated
Four core features, live today — no vaporware.
Win-back emails go out automatically at the ideal moments — day 7, day 14, and day 30 after purchase.
Review requests are sent 3 and 7 days after purchase, right when customers have actually used the product.
A single app install syncs orders and customer data automatically — no more manual CSV exports.
See send volume and segment performance in a single view.
No password sharing — one click through Cafe24's official OAuth 2.0 login.
Pick a retention or review-request template and tailor it to your brand.
From here it runs on its own — check performance anytime from your dashboard.
Compliance automation Klaviyo and Mailchimp don't build for you — starting with Korea's strict email marketing law.
We never own or continuously harvest your customer database. Retengo works only within the read-only scope you grant, and nothing is retained beyond what's needed.
Automatically tracks Korea's 6-month existing-customer exemption window under the Network Act — contacts past that window are only messaged once marketing consent is on file.
Flags contacts approaching their 2-year marketing-consent expiry and triggers a re-confirmation email automatically — a legal requirement in Korea, handled without manual tracking.
Any coupon or discount variable in a template automatically triggers a required "(Advertisement)" label plus an unsubscribe link — no manual policing needed.
OAuth tokens and customer data are never stored in plain text — everything is encrypted end to end, with a separate key per merchant.
Revoking access deletes cached data immediately — no support ticket, no approval flow, handled straight from your dashboard.
No messy CSV uploads — real-time sync through a standard OAuth 2.0 REST API. Cafe24 is fully supported today, with Naver Smart Store and Shopify on the roadmap.
Doing 100+ orders a month and losing track of repeat customers
Struggling to convert new visitors because reviews are thin
Still exporting into Mailchimp or spreadsheets by hand

Instead of unverified numbers, here's what Retengo actually automates today.
Repeat-purchase triggers
Review collection
Win-back for dormant customers
Zero manual sending
No. Cafe24 connects through official OAuth 2.0 authentication — your password is never shared with Retengo.
Beta brands get first access to our standard pricing, on the best terms we offer.
Cached data is deleted the moment you disconnect. Retengo doesn't keep a separate copy.
We don't store buyer information — it's fetched from the Cafe24 API only at send time. See our Privacy Policy for exactly what's collected, how long it's kept, and your rights.
Every email includes an unsubscribe link. Clicking it takes effect immediately and removes that contact from future sends — no approval step, no delay.
Cafe24 is fully supported today. Smart Store and Shopify integrations are next on the roadmap.
