+<br/>\
+Earlier this year, we introduced a new pricing structure for new Tolgee customers while keeping existing users on their current plans. We’re now moving all subscriptions to the new plans to make things simpler and fair for everyone.<br/>\
+<br/>\
+In the new structure, translation strings have been replaced with keys and seats to better reflect how Tolgee is used. You can view the updated pricing here <a href="https://tolgee.io/pricing">https://tolgee.io/pricing</a>.<br/>\
+<br/>\
+Your current {1} plan will automatically switch to the new {2} plan on {3}. If you’d like to explore other subscriptions options, you can do so anytime in the <a href="{4}">Subscriptions</a> section within the Tolgee platform.<br/>\
+<br/>\
+Thank you for your continued trust and support!<br/>\
+<br/>\
+P.S. I understand these changes may cause discomfort and not accommodate everyone’s circumstances. If this materially impacts your business, I warmly invite you to contact me directly for a personal dialogue regarding your concerns. You can reach me at:<br/>\
