MailOptin Update – Klaviyo API Upgrade, Improvements and More

We’re thrilled to announce our latest plugin update, MailOptin, which was released on January 18, 2024. Packed with new features, improvements, and bug fixes, we’re confident this upgrade will streamline your experience with our plugin.

Let’s delve into the fundamental changes.

What’s New:

  • Filters to Delay WooCommerce Opt-in Subscription: We have added a filter that can be used to delay subscription requests after checkout. This helps minimize potential conflicts when users are concurrently added to multiple lists post-checkout and allow for better synchronization between requests.
  • Delete-All-Log Bulk Action (Campaign Log & Leads Screen): We have added a new bulk action option to delete all logs directly from the campaign and Leads screens.


  • Klaviyo API Upgrade: We have updated our Klaviyo API integration to the latest version. This ensures smooth and seamless operation between your WordPress site and your Klaviyo account.
  • Ensure Taxonomy Existence: We have improved the email automation process to ensure the existence of a taxonomy before checking if their terms meet email automation criteria.
  • OmniSend API Keys URL: We have updated the OmniSend API Keys URL on the integrations page.


  • Webhook Integration on All Form Integrations: We have removed the webhook integration from all form integrations.

These updates aim to enhance the overall functionality and performance of the product. As always, we recommend keeping your software up to date so you can benefit from these improvements and avoid any known issues.

Be sure to update to the latest version to take advantage of this new feature. You can update your MailOptin plugin from your website’s dashboard by navigating to Dashboard>>Updates. You can also download the latest version from your MailOptin account dashboard.
