Direct Mail can import from a variety of applications and file formats, but it can also import email addresses from file formats it doesn't natively support. Here's how:
- Choose Addresses > Import from the menu bar.
- Scavenge Files/Folders from the popup menu.
- Click "Choose" to select the file you want to import from.
- Click Import.
Using this method, Direct Mail will not be able to extract any data other than email addresses.
