Translation problem with Woocommerce integration

Hello,
I use wordpress and woocommerce in French.
I have enabled the Mailjet module option that allows integration with Woocommerce.
Everything works fine except on the order confirmation page where a message in English appears while everything else is in French.
Is it a bug or a translation omission?

See screenshots :

The sentence displayed on the “order-received” page is as follows:

We have sent the newsletter subscription subscription confirmation link to you (xxxx@xxx.xx).
To confirm your subscription you have to click on the provided link.

Thank you in advance for your help.
