Advertisement appearing in an email

Greetings,

Can anyone help me understand the following:

1. Can malware be included in an email in the form of a hyperlink? Or is malware only sent in emails through attachments?

2. I sent to myself a test email to try a new email service. When opening the email, it contained the initial short message I sent, but also at the bottom an advertisement with a hyperlink, that I had in no way whatsoever included in the test message. The email service from which I sent is, presumably, trustworthy and spam free.

Is this hyperlink a form of spam or is it potential malware?

I've seen that in Gmail there are advertisements related to the content of the message, but always in the control panel, never inside the email itself.

Does anyone know in which cases an advertisement along with a hyperlink can be inserted inside an email?

Is this a known practice from third parties which may have been included in the terms of agreement, but overlooked? Or is this in all cases a malware of any sort?

Thanking you in advance for your time, I look forward to reading any replies.

 

I was reading the Thunderbird manuals yesterday . Malware can only com thru attatchments. I suggest using Ad Block Plus extension available for both Thunderbird and Firefox

 

JRViejo,

Thank you for the reply. I always appreciate a useful link.

What you say is most certainly the case: advertisements are probably included in the terms of agreement as I am using a free service.

Well, at least now I know I am sending embedded ads to the people I email. I'm not so pleased about that though. Good thing to find out. As from now on I'll always check by sending an email to myself when using a new email service.

I was however surprised because the email in question was sent using Hushmail (free version). I thought Hushmail would never do this. Guess it's reality of business.

Thanks again for the exchange,
