• I have multiple eBay ads posted but my responses always go to SPAM. How can I just let everything come to my inbox?

• Answer:

  There is no option to turn off the SPAM folder but there is a way around it. This is due to the fact that filters will operate on the INBOX and the SPAM folder. TO STOP ALL MAIL FROM GOING TO SPAM: Create a filter where all mail that does NOT have the FROM address is sent to the INBOX. Create a random FROM address that will never exist such as [email protected]. If you have other filters be sure to place this one last. TO STOP A SPECIFIC EMAIL FROM GOING TO SPAM WHERE OTHER OPTIONS FAIL: Create a filter where mail from that specific FROM address is sent to the INBOX.
