If the anchor sign is black on a yellow background then you inserted a named anchor into your signature. anchors are used to point to another location within the same email. So if you had a couple of headings which you want people to click on in order to auto jump to another section of the email without having to scroll down. You would create Named Anchors. It is a special link to jump to another section within the same email. In your case, it would appear that you may have selected 'Insert' > 'Named Anchor' and not required it ? Either create a new signature or edit the saved html file to remove the named anchor. or maybe you did something like this: Created a Named Anchor in the signature so that later you could create a link in the email to your eg: contact details which are contained in the signature? So if people click on the content link they are auto jumped down to your signature ? Very useful if you are creating a lengthy email. The Anchor sign will show when you open a new write message. Enter text and maybe a link to the named anchor. If you save the new Write email into Drafts, you will see that the 'anchor' does not show and the link to the anchor shows as an underlined hyperlink.
