The focus this round is giving you finer control over what your customers and donors see, both in their inboxes and on their recurring donation forms, plus a cleanup pass on a few rough edges around Stripe, email notifications, and shortcodes. ## What’s new in Paymattic 4.6.21 Here’s what’s touched in this update: ![Paymattic release 4.6.21](https://paymattic.com/wp-content/uploads/2026/05/Screenshot-2026-05-07-at-5.17.12-PM-1024x411.webp)Paymattic 4.6.21 Changelog Let’s walk through the highlights. ### Conditional payment method in email notifications Until now, every email notification has fired the same way regardless of which gateway processed the transaction. If you needed a different thank-you note for Stripe versus a manual confirmation for offline payments, the only way out was to clone the entire notification feed and dance around conditional logic. With 4.6.21, you can now conditionally choose which payment methods trigger which email notification. Pick one method, multiple methods, or every method per notification feed, directly from the notification settings. - *Use cases:* - **Donation campaigns** send a warmer thank-you to Stripe and PayPal donors, and a different acknowledgement for check or bank transfer contributors. - **Membership sites** that need bank transfer receipts to include manual reconciliation steps, the card receipts don’t. - **Agencies** route offline payment confirmations to a separate finance inbox while card payments stay on the customer-facing template. - **Nonprofits** are suppressing standard card receipts during a campaign, but keeping COD or check acknowledgements active. No workarounds, no duplicated feeds, one notification feed, one rule. ## Improvements: Paymattic 4.6.21 Here, we made some notable improvements to the existing features. ### Tighter Fluent Forms PDF compatibility Sites running Paymattic alongside the Fluent Forms PDF add-on were running into edge cases where the two plugins stepped on each other when generating receipts. We’ve aligned the hooks and shared data flow so PDF receipts now pull clean Paymattic transaction data without manual glue. If you ship invoices or donation receipts through Fluent Forms PDF, this one’s for you. ### Customizable labels for recurring donation billing intervals The default *Daily / Weekly / Monthly / Yearly* labels work fine for SaaS-style subscriptions, but they read clinical on a donation form. Fundraising teams have asked repeatedly to soften these for their audience. You can now override the interval labels per form, call them *Every month*, *Once a year*, *Sustainer*, or whatever fits your campaign voice. ### Translatable billing interval strings For multilingual sites, the recurring-interval strings were previously baked in and didn’t pass through translation tools. They’re now wrapped properly so WPML, Loco Translate, and Polylang can pick them up alongside the rest of the form copy. A solid win for non-English donation campaigns and global membership sites. ## Fixes: Paymattic 4.6.21 This release also ships a round of bug fixes targeting email notifications, Stripe, and shortcode rendering: - **Namespace error in email notifications** — resolved a fatal error that surfaced on some PHP environments when notification feeds were dispatched. - **Stripe “No such customer” error** — Paymattic now invalidates stale cached Stripe customer IDs and refetches from Stripe instead of failing the charge when a customer was deleted or rotated upstream. - **Payment Summary shortcode not rendering** — restored output for the Payment Summary shortcode after a regression caused it to render empty on some templates. ## Update Paymattic now!
