I just setup a new business website. Whenever I email someone from my business email address it shows up in their SPAM folder instead of their inbox. My website is legitimate, how can I stop my emails from showing in SPAM folders?

Have them set your e-mail address in their contacts list. That will identify your e-mails as coming from an approved source.

Hi, kiawah!

I agree with donf. But, are you sending these emails to people you know or don't know, please?

Thanks!

It can be your domain name, if it contains words that are in spam filters like "onlinepharmacy.info" or if it had been used for spamming by a previous owner you may have some issues. Also there are some issues with mail server configuration and DNS listings that can cause problems, however your mail is getting through and once the user moves it to the inbox or adds the address to their address book you should be good. Check with your hosting company and domain registrar for support on this issue.
Also remember the subject line needs to be clear of words associated with spam.
