Hello! I am IT Miro and I will assist you on this question.
First, always check if there is a way to unsubscribe from receiving those marketing (spam) e-mails. If the e-mails come from companies, but not from the individuals, then there should most likely be a small "Unsubscribe" link available at the bottom of the e-mail. If there is, click there in order to stop receiving any further e-mail.
However, if there is no "Unsubscribe" link or if that just doesn't work, then you can open the e-mail source (header) to verify the sender's e-mail address. I do not have an account with Network solutions, so I cannot provide the instructions where to click to access the e-mail source (header), but it is usually available on the e-mail screen, so check for all options once you open an e-mail.
When the e-mail source (header) is opened, it will show all kinds of text. Easiest way of searching for the e-mail addresses would be to look for the @ symbol. That way you can see all involved e-mail addresses.
You can also do that in Outlook by following these instructions:
1. Locate a spam e-mail in Outlook and double-click it in order to open it in full screen
2. At the top, click on the Actions
button and then select Other Actions > View Source
3. A new text document will open containing all kinds of information about the selected e-mail. Search for the @ symbol to get all the e-mails
Also, when blocking e-mail addresses / domains, looks for examples if they are available at the Network Solutions site. You may need to use wild card (*), something like this:[email protected]
instead of just @domain.com
I hope this helps!
Let me know if you require further assistance.
