Where can I edit text in the following email?

Where can I edit text in the following email? Not the title, but the text.

Thanks for spending time with us

thanks

Admin, customize, text, then search for that text.

Thanks! I forgot that I could modify not only title but also text with this function.

Hi!

Does it work the same way? It seems I cannot change the body message:

I believe that that message title corresponds to this body. You can edit this by going to Customise → Text

system_messages.welcome_tl1_user.text_body_template

oh my, that was really stupid of me to overlook this part… Thank you so much, you’ve saved me!
