Hi,
Thank you for reaching out. This is Abivarman from Flycart Support Team.
Are you trying to translate texts from the Checkout Upsell for WooCommerce?
If so, we recommend using plugins like Loco Translate, to translate texts like Offer and Frequently Bought Together.
Here is the link to the plugin: https://ww.wp.xz.cn/plugins/loco-translate/
Check out this doc to know more about how to translate strings using loco translate: https://docs.flycart.org/en/articles/8360284-translate-checkout-upsell-using-loco-translate
Regarding customization of emails sent to customers. Could you confirm which email you are referring to? The upsell plugin does not send any emails to customers by default. To better assist you with your issue, could you please submit a support ticket on our website at https://www.flycart.org/support?
We’ll be happy to help you further!
Thanks
Flycart Team
