Connect ConvertKit and Stripe to Automate Your Creator Business
Sync payment events from Stripe directly into ConvertKit to send perfectly timed emails, tag subscribers by purchase behavior, and grow revenue without babysitting your tools.
ConvertKit + Stripe integration
ConvertKit and Stripe do different jobs — one runs your email list, the other runs your payments. But when they don't talk to each other, things fall through the cracks fast. A new purchase goes unacknowledged for hours. A failed payment gets no follow-up. A cancellation leaves someone in the wrong sequence. Connecting ConvertKit with Stripe on tray.ai means every payment event — success, failure, cancellation — instantly triggers the right email sequence, tag, or subscriber update, without you touching a thing.
For creators, course sellers, and digital product businesses, email marketing and payment processing can't really be separated. A customer who just bought something through Stripe deserves an immediate, personal onboarding sequence in ConvertKit — not a generic welcome email that shows up three hours later. A subscriber whose card declined needs a dunning campaign, not silence. Connecting ConvertKit and Stripe through tray.ai turns payment events into real-time email automation triggers. No more exporting CSVs, manually updating tags, or cross-referencing purchase records. The revenue workflows just run.
Automate & integrate ConvertKit + Stripe
Automating ConvertKit and Stripe business processes or integrating data is made easy with Tray.ai.
Use case
Instantly Onboard New Customers After a Stripe Purchase
When a customer completes a payment in Stripe, tray.ai adds them to the right ConvertKit sequence with the right tags applied — whether they bought a course, membership, or digital product. Every new buyer gets a timely, relevant onboarding experience without any manual list management. Better first impressions, stronger product adoption from day one.
- Zero lag between purchase completion and the first onboarding email
- Accurate tagging based on specific Stripe product or price ID purchased
- No more manual CSV imports or copy-paste subscriber additions
Use case
Recover Failed Payments with Automated Dunning Sequences
When Stripe fires a payment failure or card decline event, tray.ai immediately tags the affected subscriber in ConvertKit and enrolls them in a dunning email sequence. These emails prompt customers to update their billing details before their access lapses — recovering revenue that would otherwise just disappear. Once Stripe confirms a successful retry, the dunning tag comes off automatically.
- Notify subscribers the moment a payment fails in Stripe
- Automatically remove dunning tags once payment is successfully retried
- Protect subscription MRR without manual intervention
Use case
Segment Email Lists by Product or Subscription Tier
Different Stripe products and price plans mean different customer segments, and your emails should reflect that. tray.ai maps Stripe product metadata to ConvertKit tags and custom fields, so subscribers are automatically segmented by what they've purchased or which plan they're on. Upsell sequences and tier-specific announcements actually feel relevant because they're based on real purchase data.
- Apply granular ConvertKit tags based on Stripe product ID or plan name
- Send upgrade campaigns to lower-tier subscribers automatically
- Personalize email content using Stripe purchase data stored as ConvertKit custom fields
Use case
Remove or Update Subscribers When Subscriptions Are Cancelled
When a customer cancels their Stripe subscription, tray.ai detects the event and updates their ConvertKit profile right away — applying a cancellation tag, removing active-member tags, and enrolling them in a win-back sequence. Cancelled customers stop receiving active-member emails, and you get an automated shot at winning them back. Your list stays clean, your segments stay accurate.
- Automatically move churned customers into a dedicated win-back sequence
- Remove premium content access tags immediately upon cancellation
- Keep ConvertKit subscriber segments accurate without manual cleanup
Use case
Reward and Upsell Loyal Long-Term Subscribers
Using Stripe subscription anniversary and billing milestone events, tray.ai can trigger ConvertKit sequences that hit long-term subscribers with exclusive offers, upgrade invitations, or thank-you content. Reaching them at the right moment measurably improves upsell conversion rates. Without automation, this kind of lifecycle marketing is nearly impossible to pull off at scale.
- Trigger anniversary emails automatically at 30, 90, or 365-day subscription milestones
- Deliver exclusive upgrade offers to high-LTV customers at the right moment
- Strengthen customer relationships with personalized loyalty touchpoints
Use case
Gate Content Delivery Behind Stripe Payment Confirmation
For creators selling digital downloads, courses, or gated newsletter tiers, tray.ai verifies a successful Stripe payment before triggering a ConvertKit email that delivers protected content or access credentials. Nothing goes out until the payment clears. The entire delivery workflow runs automatically, so buyers get a smooth, professional experience and you don't have to chase down access requests.
- Confirm payment success in Stripe before triggering content delivery emails
- Automate delivery of download links, access codes, or login credentials via ConvertKit
- Reduce support tickets from customers who didn't receive their purchase
Challenges Tray.ai solves
Common obstacles when integrating ConvertKit and Stripe — and how Tray.ai handles them.
Challenge
Matching Stripe Customers to ConvertKit Subscribers Reliably
Stripe customers and ConvertKit subscribers live in separate systems with no shared identifier, so linking a payment event to the right email subscriber gets complicated — especially when customers check out with a different email than the one on their list.
How Tray.ai helps
tray.ai's workflow logic lets you build matching rules that look up subscribers by email, fall back to custom field values like a Stripe customer ID stored in ConvertKit, and handle edge cases like duplicate or mismatched records — so every Stripe event lands on the right subscriber.
Challenge
Handling Stripe Webhook Reliability and Event Ordering
Stripe sends webhook events in near-real-time, but they can occasionally arrive out of order or fire more than once. Without proper handling, that means duplicate tags or sequences firing multiple times in ConvertKit.
How Tray.ai helps
tray.ai has built-in idempotency handling and conditional logic that checks whether an action has already been performed before executing it, preventing duplicate tags or sequence enrollments from Stripe's webhook retry mechanism.
Challenge
Mapping Multiple Stripe Products to the Right ConvertKit Sequences
When you sell multiple products, plans, and price tiers in Stripe, each one typically maps to a different ConvertKit tag, custom field, or sequence. Maintaining that mapping manually is error-prone, and it gets messier as your product catalog grows.
How Tray.ai helps
tray.ai's branch and lookup table logic lets you define a centralized mapping between Stripe price IDs or product names and their corresponding ConvertKit tags and sequences. When your catalog changes, you update the mapping in one place — no rewriting entire workflows.
Templates
Pre-built workflows for ConvertKit and Stripe you can deploy in minutes.
Stripe Payment Succeeded → Add ConvertKit Subscriber and Tag
Stripe 
ConvertKit This template listens for successful charge or payment intent events in Stripe, then creates or updates the corresponding subscriber in ConvertKit, applies a product-specific purchase tag, and enrolls them in the designated onboarding sequence — all in real time.
Stripe Payment Failed → Enroll Subscriber in Dunning Sequence
Stripe ConvertKit This template triggers when Stripe reports a failed payment or invoice payment failure, immediately tagging the affected ConvertKit subscriber and enrolling them in a dunning recovery email sequence to prompt them to update their billing details before access is revoked.
Stripe Subscription Cancelled → Move Subscriber to Win-Back Flow
Stripe ConvertKit When a Stripe subscription cancellation event is detected, this template updates the subscriber's tags in ConvertKit to reflect their churned status and moves them into a win-back email sequence designed to re-engage them with a targeted offer or feedback request.
New ConvertKit Purchase Tag → Create or Update Stripe Customer Record
ConvertKit Stripe This reverse-direction template watches for a purchase-indicating tag being applied in ConvertKit — such as from a third-party checkout — and creates or updates the corresponding customer record in Stripe, keeping billing and email data in sync.
Monthly Stripe Revenue Summary → ConvertKit Broadcast to Stakeholders
Stripe ConvertKit This template runs on a schedule, pulling the prior month's revenue and subscriber growth data from Stripe, then composing and sending a ConvertKit broadcast to an internal stakeholder list or investor update segment with business metrics.
Stripe Subscription Renewal → Trigger Re-Engagement or Upsell Email
Stripe ConvertKit Each time a Stripe subscription successfully renews, this template fires an automated ConvertKit email that either thanks the customer for their continued loyalty, delivers a member-exclusive offer, or presents a contextual upsell based on how long they've been subscribed.
