"Append n8n Attribution" breaks e-mail

[MinecollYT]

Bug Description

I kept the exact same workflow, nothing changes besides for one I unticked the "Append n8n Attribution". Without the attribution the html seems to break, but for whatever reason the html looks better when its turned off

To Reproduce

1. Use Send Email Node
2. Turn "Append n8n Attribution" on/off
3. Look at the original e-mail file if the change in html is not visible directly

Expected behavior

No change in html when changing the "Append n8n Attribution" value

Operating System

docker (self-hosted)

n8n Version

1.75.2

Node.js Version

20.18.1

Database

SQLite (default)

Execution mode

main (default)
