Email addresses being formatted as links

I just noticed in one of my articles, emails such as me@example.com are formatted as links in the output. Is this a Hugo thing or not related at all?

Linkification is a goldmark configuration option: Configure Markup | Hugo

Do I set linkify = false?

If your config is in yaml, try:

markup:
  goldmark:
    extensions:
      linkify: false

Adapt the syntax if your config is in toml or json.

Mine is TOML. I will try that. Thanks.
