If you run a SaaS business on Stripe, your email tool needs to talk to Stripe. Not through a Zapier hack that breaks when Stripe changes their webhook format. Not through a CSV export you remember to run on Tuesdays. Natively. In real time.

When someone's trial expires, their payment fails, or they upgrade to a higher plan, your email system should know about it instantly and react automatically. That's what Stripe integration actually means in practice.

I've tested every major email platform's Stripe integration. Some are genuinely native. Some are glorified webhook listeners. Some require so much setup that you might as well build it yourself. Here's the honest breakdown.

What "Stripe Integration" Actually Means

Before comparing tools, let's clarify what we're looking for. A real Stripe integration should:

Sync subscription events automatically: New subscriptions, cancellations, upgrades, downgrades, trial starts/ends, and payment failures should flow into your email tool without code.
Tag or segment subscribers by status: Your email tool should know who's a paying customer, who's on a trial, who's churned, and who has a failed payment.
Trigger automations based on Stripe events: When a payment fails, a dunning sequence starts. When someone upgrades, the upsell sequence stops. Automatically.
Sync revenue data: Ideally, your email tool knows each subscriber's MRR, plan name, and billing interval so you can segment by value.

Anything less than this and you're doing manual work that should be automated.

The 8 Best Email Tools With Stripe Integration

1. Sequenzy

Best for: SaaS founders who want Stripe automation without code

Sequenzy was built specifically for SaaS, and the Stripe integration reflects that. It's a native OAuth connection (Settings > Integrations > Connect Stripe), not a webhook configuration.

Once connected, Sequenzy automatically:

Creates events for every subscription lifecycle action (purchase, cancellation, payment failure, upgrade, downgrade, trial start/end)
Applies status tags to subscribers (customer, trial, cancelled, churned, past-due)
Syncs subscription attributes (MRR, plan name, billing interval)
Fires automations based on any of these events or tags

The key differentiator is that you don't configure any of this. Connect Stripe and it all works. There's no webhook URL to copy, no event mapping to set up, and no custom fields to configure.

Pricing: Starts at $29/month Pros:

Native OAuth connection, zero configuration
Automatic event creation and subscriber tagging
Built-in dunning, trial conversion, and lifecycle sequences
Revenue data syncs to subscriber profiles
Both transactional and marketing email in one platform

Cons:

Newer platform (launched 2025)
No SMS channel
Smaller template library than established competitors

2. Customer.io

Best for: Technical teams wanting flexible event-driven automation

Customer.io has solid Stripe support through their data integration layer. You can connect Stripe events via their API or through Segment, and use them to trigger workflows.

The integration is powerful but requires more setup than plug-and-play solutions. You'll need to map Stripe events to Customer.io events and configure which attributes to sync. For technical teams comfortable with APIs, this flexibility is a strength.

Pricing: Starts at $100/month (Essentials plan) Pros:

Flexible event-driven automation engine
Can handle complex multi-step workflows
Good API and webhook support
Supports both email and push notifications

Cons:

Requires technical setup for Stripe integration
Expensive for small teams
Steeper learning curve
No native one-click Stripe connection

3. Userlist

Best for: SaaS companies wanting clean lifecycle segmentation

Userlist positions itself as email for SaaS, and the Stripe integration is decent. You connect via API and can sync subscription data to create segments based on plan, status, and trial state.

The automation builder is straightforward and supports Stripe event triggers. It handles the common SaaS use cases (trial conversion, dunning, lifecycle) well.

Pricing: Starts at $149/month Pros:

Built specifically for SaaS
Clean segmentation by subscription status
Supports both user and company-level data
Good for B2B SaaS with multiple users per account

Cons:

Higher starting price
Stripe integration requires API work
Smaller community and fewer resources
Limited template options

4. Loops

Best for: Founders who want a modern, simple email tool

Loops is a newer email platform that's popular with indie hackers and early-stage SaaS founders. The Stripe integration works through their API and event system.

You send events from your app when Stripe webhooks fire, and Loops triggers automations based on those events. It's not a direct Stripe connection, but the event-driven model works cleanly.

Pricing: Free for up to 1,000 contacts, then starts at $49/month Pros:

Clean, modern interface
Simple event-driven automation
Good free tier for early-stage
Fast setup

Cons:

No native direct Stripe integration (requires you to forward events)
Limited segmentation compared to more mature tools
Newer platform with fewer features
Basic analytics

5. Encharge

Best for: Non-technical teams wanting visual Stripe automation

Encharge offers a visual flow builder with Stripe as a native trigger source. You can connect Stripe directly and build visual automations that respond to subscription events.

The visual builder makes it easy to see the logic of your automation flows, which is helpful for non-technical founders who want to understand what's happening.

Pricing: Starts at $79/month Pros:

Visual flow builder with Stripe triggers
Relatively easy setup
Good for non-technical users
Supports common SaaS automation patterns

Cons:

Visual builder can get complex for sophisticated flows
Mid-range pricing
Smaller user base than major platforms
Email editor is basic

6. Mailchimp (with Stripe Add-on)

Best for: Companies already on Mailchimp who want basic Stripe data

Mailchimp offers a Stripe integration through their marketplace. It syncs customer data and purchase history, allowing you to segment by purchase behavior.

However, the integration is limited compared to SaaS-focused tools. It's designed more for e-commerce (one-time purchases) than subscription lifecycle management. You won't get native trial/churn/dunning triggers without significant custom work.

Pricing: Free for up to 500 contacts, paid plans from $13/month Pros:

Familiar interface if you already use Mailchimp
Large template library
Wide ecosystem of integrations
Generous free tier

Cons:

Stripe integration is basic and e-commerce-focused
No native subscription lifecycle triggers
No trial conversion or dunning automation out of the box
Gets expensive at scale

7. ActiveCampaign

Best for: Teams wanting CRM + email with Stripe data

ActiveCampaign connects to Stripe through their native integration and third-party connectors. You can sync customer data, trigger automations on purchase events, and segment by Stripe attributes.

The CRM component is useful if you want to track individual customer relationships alongside email automation. But for pure SaaS lifecycle email, the Stripe integration requires more configuration than dedicated SaaS tools.

Pricing: Starts at $29/month (Lite plan) Pros:

Built-in CRM alongside email
Mature automation builder
Large ecosystem of integrations
Good deliverability reputation

Cons:

Stripe integration requires setup and may need Zapier for some events
Not purpose-built for SaaS subscription management
Complex interface with steep learning curve
Pricing increases significantly with contacts and features

8. Postmark (Transactional Only)

Best for: Developers who need transactional email triggered by Stripe webhooks

Postmark isn't an email marketing platform. It's a transactional email service with exceptional deliverability. You'd use it alongside Stripe by sending transactional emails (receipts, payment confirmations, dunning notices) directly from your application when Stripe webhooks fire.

No automation builder, no sequences, no marketing campaigns. But for pure transactional email triggered by Stripe events, it's hard to beat on deliverability and speed.

Pricing: Starts at $15/month for 10,000 emails Pros:

Best-in-class transactional deliverability
Fast delivery (seconds, not minutes)
Clean API and excellent documentation
Template system for transactional emails

Cons:

No marketing email capabilities
No automation or sequences
Requires development work to integrate with Stripe
You'll need a separate tool for marketing email

How to Choose

If you want zero-configuration Stripe automation: Sequenzy connects via OAuth and handles everything automatically. No webhook setup, no event mapping.

If you're technical and want maximum flexibility: Customer.io gives you the most control over how Stripe data flows into your email automation.

If you're already using a tool and just want to add Stripe data: Check if your current platform supports it natively before switching. ActiveCampaign and Mailchimp both have some Stripe connectivity.

If you only need transactional email: Postmark is the deliverability king for receipts, payment confirmations, and other Stripe-triggered system emails.

What to Look For in a Stripe Integration

When evaluating any email tool's Stripe integration, ask these questions:

Is it native or through a third party? Native integrations are more reliable and require less maintenance.
Does it handle all subscription events? Payment failures, cancellations, upgrades, and trial events should all be supported.
Does it auto-tag subscribers? Manually tagging customers by subscription status defeats the purpose of automation.
Does it sync revenue data? Knowing each subscriber's MRR lets you segment by customer value.
What happens when Stripe changes their API? Native integrations handle this for you. Custom webhook setups may need updating.

FAQ

Do I need a Stripe integration if I already use Zapier? Zapier works as a bridge, but it adds cost ($20+/month), latency (minutes vs. seconds), and a potential point of failure. For critical flows like dunning, a native integration is more reliable. For non-critical flows, Zapier is fine.

Can I use multiple email tools with Stripe? Yes, but be careful about duplicate emails. If both your transactional service and marketing platform listen to Stripe events, make sure they're handling different use cases (receipts vs. lifecycle sequences).

What Stripe events matter most for SaaS email? The critical ones: customer.subscription.created, customer.subscription.deleted, invoice.payment_failed, customer.subscription.trial_will_end, and customer.subscription.updated. These cover the core lifecycle.

How fast should the integration sync? For dunning emails, speed matters. A payment failure should trigger the first email within minutes, not hours. For other events like upgrades or cancellations, a delay of a few minutes is acceptable.

What if I switch payment processors later? If you're deeply integrated with a tool that has native Stripe support, switching payment processors means rebuilding that integration. Consider whether the tool also supports Paddle, Chargebee, or your potential future processor.
