How to remove logo in email content of my notification?

Just curious now why I see the original logo for a different company in my
email notifications of form submissions?

On testing the cloned version of your form I found a different logo embedded in your email content. If this is what you don't want in your notification emails then you can remove the logo and insert your company logo there.

You can edit your notification and autoresponder emails. You can insert the new image here.

You can follow this guide:
