Como importar contactos no gmail:
Importing contacts
You can import address books from Outlook, Hotmail, Yahoo!, orkut, and other services into Gmail. Importing your contacts isn't difficult, but it does take a few steps.
First, you'll need to format your contacts as a CSV file -- often times, address books exported from other mail providers are already formatted as CSV files. You can also create your own CSV file.
Once you have a CSV file with all your contacts' information, you can import the file and transfer your contacts to Gmail. Note that you can only import up to 3000 contacts at a time. If you have more than 3000 contacts, you'll need to create multiple CSV files to upload.
Resumindo:
Importas os contactos do msn para o gmail e depois envias o cooof, coof..."spaMAIL"...cof.
Segundo li,
algures, existe um limite de 500 recipientes por mensagem.
