How do you get your sent mail not to go to the receiver's junk mail box
You don't get a choice.
You don't get to define the recipient's rules.
You don't get to modify the recipient's spam filters.
You aren't in control of delivery of your e-mails.
You could ask the recipient to add you to their whitelist.
You could check your e-mails that they don't qualify as spam.
You could ensure that you aren't on any public DNS blacklists.
