原文外掛簡介
Thanks Mail for Stripe is a lightweight plugin that automatically sends customized thank-you emails to customers after they complete a purchase through Stripe Payment Links. Perfect for digital product sales, software licensing, and service businesses.
No external services required – works directly with Stripe Webhooks
This plugin receives Stripe webhook events directly and sends emails using WordPress’s built-in mail function. No Zapier, Make, or other third-party automation services needed.
Key Features
Automatic Email Sending – Sends thank-you emails automatically via Stripe Webhook
Multi-language Support – Up to 10 customizable email templates with locale settings
Smart Language Detection – Automatically detects customer language from Payment Link ID or locale
Customizable Templates – Fully customizable email subject and body with placeholders
Custom Sender Settings – Set custom From email address and sender name
Duplicate Prevention – Built-in idempotency prevents sending duplicate emails
Test Email Function – Send test emails to verify your settings before going live
Email Log – View history of sent emails in the admin panel
Secure Webhook Verification – Validates Stripe webhook signatures (HMAC-SHA256)
How It Works
Customer makes a purchase via your Stripe Payment Link
Stripe sends a webhook event to your WordPress site
Plugin verifies the webhook signature for security
Plugin detects customer language based on Payment Link ID
Thank-you email is sent to the customer using wp_mail()
Transaction is logged to prevent duplicate sends on retries
Use Cases
Digital product sales (software, ebooks, courses)
Software license key distribution (manual follow-up)
Service booking confirmations
Donation thank-you messages
Any Stripe Payment Links checkout
Requirements
WordPress 5.0 or higher
PHP 7.4 or higher
Stripe account with Payment Links
SSL certificate (HTTPS) – required for webhooks
SMTP plugin recommended for reliable email delivery
Email Sender Best Practices
Important: Always use your own domain email address as the “From Email” setting.
Good: [email protected], [email protected]
Bad: [email protected], [email protected]
Using Gmail or other free email services as the sender will cause delivery failures due to SPF/DKIM/DMARC authentication. Your server is not authorized to send emails on behalf of Gmail.
You CAN use any email address (including Gmail) for the “Reply-To” setting – this only affects where replies go, not email deliverability.
Recommended SMTP Plugins
For reliable email delivery, we recommend using an SMTP plugin:
WP Mail SMTP
Post SMTP
FluentSMTP
These plugins send emails through a proper SMTP server instead of PHP’s mail() function, improving deliverability.
Test vs Live Mode
Remember to update your settings when switching from test to live mode:
Webhook Signing Secret – Test and Live have different secrets (whsec_…)
Payment Link IDs – Test and Live have different IDs (plink_…)
Webhook Endpoints – Register endpoints in both Test and Live mode in Stripe Dashboard
Security Best Practices
The plugin verifies Stripe webhook signatures using HMAC-SHA256
Webhook requests are validated within a 5-minute tolerance window
Session IDs are stored to prevent duplicate email sends
All settings are properly sanitized and escaped
Available Filter Hooks
The plugin provides filter hooks for customization:
tmfs_email_headers – Modify email headers before sending
tmfs_email_subject – Customize email subject
tmfs_email_body – Customize email body
tmfs_detect_language – Override language detection logic
Example: Add CC to emails
add_filter( 'tmfs_email_headers', function( $headers, $to, $lang, $session_id ) {
$headers[] = 'Cc: [email protected]';
return $headers;
}, 10, 4 );
Example: Custom language detection
add_filter( 'tmfs_detect_language', function( $lang, $session ) {
// Custom logic based on session data
if ( strpos( $session['customer_details']['email'], '.jp' ) !== false ) {
return 'ja';
}
return $lang;
}, 10, 2 );
Database Table
The plugin creates a table {prefix}stm_sent_emails to track sent emails:
id – Auto-increment ID
session_id – Stripe Checkout Session ID (unique)
email – Customer email address
lang – Detected language (ja/en)
product_name – Product name (if available)
amount – Purchase amount
sent_at – Timestamp when email was sent
Troubleshooting Webhook Issues
If webhooks aren’t working, check these common issues:
SSL Certificate – Stripe requires HTTPS for webhooks
Webhook URL – Make sure the URL is correct and accessible
Signing Secret – Verify you’re using the correct secret for test/live mode
Server Firewall – Some hosts block requests from overseas IPs
Security Plugins – May block REST API endpoints
WAF Rules – Server-level WAF may block webhook requests
Check Stripe Dashboard > Developers > Webhooks for detailed error logs.
Data & Privacy
This plugin stores email delivery logs in your WordPress database to prevent duplicate sending and allow administrators to verify delivery history. No data is transmitted to external services by this plugin.
What Data Is Stored
The plugin stores the following data in a custom database table ({prefix}stm_sent_emails):
session_id – Stripe Checkout Session ID (used as unique key for duplicate prevention)
email – Customer email address (to confirm which customer received the email)
lang – Detected language code, ja or en (to record which template was used)
product_name – Product name (reserved for future use)
amount – Purchase amount and currency (for administrator reference)
sent_at – Timestamp when the email was sent
Additionally, plugin settings (webhook secret, email templates, Payment Link IDs, etc.) are stored in the wp_options table under the key stm_settings.
Purpose
Duplicate prevention – Stripe may retry webhook events; the session ID prevents sending the same email twice
Delivery confirmation – Administrators can verify that emails were sent to the correct address
Customer support – Transaction reference for handling customer inquiries
Data Retention
Email logs are stored indefinitely by default
Administrators can manually delete individual records via database access
All data (logs and settings) is automatically removed when uninstalling the plugin via the WordPress admin
External Services
This plugin receives incoming webhook events from Stripe – it does not make outbound API calls to Stripe
No customer data is sent to any third-party service by this plugin
Emails are sent using WordPress’s built-in wp_mail() function (delivery depends on your server or SMTP plugin configuration)
GDPR Considerations
Customer email addresses are stored for the legitimate business purpose of preventing duplicate emails and maintaining delivery records
You should disclose this data storage in your site’s privacy policy
Data can be exported or deleted upon customer request via direct database access
