In addition, to prevent Junk filtering of your emails (and optimize email deliverability), it’s a good practice to request your Outlook recipients to add your address to their Safe Sender List. E.g. you could write them a note like this:
Please add our “from” address (youremail@yoursite.com) to your Safe Senders list.
To add us to your Safe Senders list:

1. On the “Tools” menu, click “Options”.
2. On the “Preferences” tab, click “Junk Email”.
3. On the “Safe Senders” tab, click “Add”.
4. In the “Add Address” field, enter “youremail@yoursite.com”.
5. Click “OK”.
