Free trials reduce signup friction and let customers experience your product's value before paying. They are one of the most effective conversion tactics for subscription products — well-designed trials can lift signup conversion rates 2-3× compared to direct purchase.
This guide shows how to add a free trial to a WooCommerce subscription product using WPSubscription, configure how long the trial lasts, and set up the automatic billing transition when the trial ends.
Why This Matters
Free trials dramatically reduce the perceived risk of subscribing, expanding your top-of-funnel reach. Trials that collect a credit card at signup convert to paid at 40-60% rates while no-card trials convert at 10-25% — but no-card trials produce 3-4× more signups.
Beyond conversion, trials produce higher-quality subscribers: customers who experience the product before paying are more committed and churn less than impulse buyers. Trials also serve as a marketing channel even when users don't convert — they see your product, may refer friends, and represent future re-engagement opportunities.
Before You Start
- WPSubscription installed and activated
- At least one subscription product already created
- A payment gateway configured that supports trial periods (Stripe and PayPal both support this)
- WP Mail SMTP or equivalent configured for reliable email delivery
- A trial-end reminder email template ready (WPSubscription provides defaults you can customize)
Step-by-Step Instructions
Open the subscription product for editing
Go to Products in your WordPress admin and click Edit on the subscription product you want to add a trial to. In the "Product data" panel, confirm the product type is set to "Simple subscription" or "Variable subscription".
If you do not see these options, ensure WPSubscription is activated. The trial settings appear in the WPSubscription panel within the product data area.
Enable and configure the trial period
In the WPSubscription product settings panel, locate the "Free trial" field. Enable the trial and enter the trial length in days — 7, 14, or 30 are the most common choices.
Save the product. The product page will now show the trial period prominently in the subscription terms (e.g., "14 days free, then $39/month").
Match trial length to your product's typical time-to-value: short for products with immediate value, longer for products requiring setup time.
Configure trial notification email timing
Go to WPSubscription → Settings → Emails. Find the "Trial ending" notification and configure how many days before trial expiry the reminder email is sent.
A 2-3 day reminder is recommended — it gives customers time to cancel if needed and reduces surprise billing disputes. Also enable a welcome email at trial start and an engagement email at mid-trial.
The three-email sequence (welcome, engagement, reminder) is proven to lift trial-to-paid conversion by 15-25%.
Customize trial email templates
Edit each trial-related email template to match your brand voice. The welcome email should set expectations and provide a quick-start guide.
The mid-trial email should highlight features users may have missed. The trial-ending reminder should be friendly but clear: "Your trial ends in 2 days.
We'll charge $39 on March 15 unless you cancel — here's your account link." Use WPSubscription's template variables for customer name, product name, trial end date, and billing amount.
Test the trial signup and transition
Complete a test purchase of the trial product using your gateway's test mode. Confirm the subscription shows a "Trial" status in WooCommerce → Subscriptions and that no charge has been made.
Verify the welcome email was sent. Use Stripe's test clock (or wait for the actual trial period) to verify the first billing charge fires correctly at the trial end date and the subscription transitions from "Trial" to "Active" status.
Also test the cancellation flow during trial — ensure cancelling produces no charge.
Monitor trial-to-paid conversion
After launch, monitor trial conversion rate weekly by checking WooCommerce → Subscriptions and filtering by subscriptions that moved from "Trial" to "Active" status. Track conversion by signup source if you use UTMs — different acquisition channels often produce dramatically different conversion rates.
If conversion is below 30% (for card-required trials), review your mid-trial engagement emails, time-to-value in your onboarding, and whether your product delivers clear value within the trial window.
Pro Tips
- Require a credit card at trial signup — paid conversion is 2-3× higher than no-card trials
- Keep trial length to 7-14 days — longer trials reduce urgency without improving conversion
- Send 3 emails during trial: welcome (Day 0), engagement (mid-trial), reminder (2 days before end)
- Track trial-to-paid conversion by signup source — identifies which marketing channels deliver quality leads
- Test cancellation during trial yourself — friction here causes chargebacks instead of clean cancellations
Result
Your subscription products now offer a free trial period with automated billing transition at trial end. Customers experience your product before paying, while WPSubscription handles the trial timeline, three-email engagement sequence, and seamless billing start — all without admin intervention.
Troubleshooting
Problem:Payment gateway is charging customers immediately despite the trial being configured
Solution:Not all payment gateways support zero-amount trial authorization. With Stripe, confirm "Trial period" support is enabled in gateway settings. For PayPal, trial periods require Reference Transactions to be enabled on your PayPal Business account — contact PayPal support to request this if it is not already enabled (can take 1-5 business days).
Problem:Trial ending email is not being sent
Solution:Check WPSubscription → Settings → Emails and confirm the trial ending notification is enabled. Also check WooCommerce → Status → Logs for email delivery errors. Verify your site's email deliverability using WP Mail SMTP — WordPress's default mail function frequently fails or is filtered as spam. Send test emails to confirm delivery works.
Problem:Customers are completing trial but never converting to paid
Solution:Two common causes: first, the customer is forgetting about the product during trial — fix with mid-trial engagement emails. Second, the customer is not experiencing value in the trial window — fix with better onboarding, time-to-value reduction, or longer trial period. Track which step of your onboarding flow customers reach to identify drop-off points.
Problem:Same customer signing up for multiple trials with different emails
Solution:WPSubscription tracks trial usage per customer account. To prevent the same person from gaming the system with new accounts, enable email verification at signup and consider IP-based or device-fingerprint blocking via third-party fraud tools. For most stores, this is a minor issue not worth heavy investment in prevention.
