gmailspam-prevention
Whenever I send a mail from myaccount@example.com to a Gmail account, Gmail treats it as spam.
I'm talking about the one e-mail I send to a prospect after I've met him (it is surely non-spam mail). It's happened several times already:
"Hey!, you never sent that e-mail you promised me" the prospect says.
"How come…? I did send it. Check the spam e-mail" I answer.
"Oh, there it is…"
I think it has to do with example.com not being a well-known domain.
How/Where should I complaint about this?
Gmail's spam filters aren't simply based on the Senders email address. And it is also dependent on other users flagging similar emails as spam. Gmail determines that a particular email is spam by seeing how the global gmail community sees that email.
If all this spam / unwanted messages are coming from a single email address then you can set up a filter to send all email from that sender to spam. Filters affect just your email account.
Go to Settings, select "Filters". Scroll to the bottom and select "New filter". Put @domain.com in the from field. If you want it to only check email that have gone to spam, put in:spam in the has the words field. Now click "Create filter with this search":
Now, an new window will appear. Tick "Delete it", then click "Create filter", and you ought to be ready to go!
