Google provides extensive documentation on using Gmail.
Some of the specific questions we have been asked are listed and answered below:
- How do I send an email to a list of addresses in a spreadsheet?
To upload a spreadsheet of contacts, it needs to be saved as a .csv file. This means a "comma separated values" file as opposed to an Excel file. You can mark this when you go to "Save As" and use the drop-down box to change the type of file.

That's really the trickiest part, because importing it into Gmail is easy. Go to Contacts (by clicking the arrow next to "Mail") and then there is a button with the word "More" on it. Clicking "More" will give you options including "Import." You can then choose the file.
