This document contains all the information related to installment completion notifications, email customization, and activation.
Overview
“Installment Complete” is the email notification sent automatically when a customer has successfully paid the final installment of their subscription plan.
This notification confirms that the installment schedule has ended, provides a summary of payments, and reassures customers that no further charges will be applied.
The email includes:
- Subscription start date
- Subscription ID
- Payment method
- Product details (title, variation, quantity, and price)
- Subtotal
- Shipping
- Taxes
- Discounts
- Total amount
- Installment schedule with due dates, status, and amounts
The email also allows you to reinforce brand value and encourage future purchases.
Pre-requisites: Before enabling email notifications, ensure your WordPress site is configured to send emails:
- SMTP plugin required: WordPress doesn’t reliably send emails by default. Install and configure an SMTP plugin like WP Mail SMTP.
- Email service provider: Connect your SMTP plugin to a transactional email service (Brevo, Mailgun, SendGrid, Amazon SES, or your hosting provider’s SMTP).
- Match sender details: Ensure that the From Email and From Name values configured in Sublium Subscriptions email notifications exactly match the sender details set in your SMTP plugin.
- Test your setup: Send a test email from your SMTP plugin to confirm emails are delivering before enabling Sublium notifications.
Without proper email configuration, notifications will fail silently.
For more details, refer to our doc on how to set up WP SMTP.

How To Activate
To activate the Installment Complete email, turn ON the toggle next to the notification inside Sublium Subscriptions.
This setup ensures customers are informed when their installment plan is fully completed, provides closure, and helps reinforce trust and engagement in your subscription service.
Troubleshooting
Emails not sending
- Confirm your SMTP plugin is configured and sending test emails successfully
- Check your SMTP plugin’s email logs for failed delivery attempts
- Verify the notification toggle is enabled
- Ensure the customer has a valid email address on their order
Merge tags showing as plain text
- Confirm you copied the full merge tag, including the curly braces, e.g., {{subscriber_first_name}}
- Check for extra spaces inside the merge tag
- Use only merge tags from the official list; custom tags won’t work
Email is going to spam
- Configure SPF, DKIM, and DMARC records for your sending domain
- Avoid spam trigger words in your subject line
- Use a reputable transactional email service
Email looks broken or unstyled
- Test across multiple email clients (Gmail, Outlook, Apple Mail)
- Avoid complex CSS, as email clients have limited style support
- Use the Visual Editor’s built-in templates for better compatibility
