Checking on whether email has gone to the spam folder and whitelisting in Gmail
If you suspect email that you wished to receive in the Inbox for your
has, instead, gone to the Spam folder, there are several
ways to check the Spam folder in
Gmail. If email you do want to read has gone into that folder, you can
whitelist email from a particular
sender or domain to ensure that future email from the sender(s) won't
be routed to the Spam folder instead of the Inbox.
