Mail Merge using Google Docs?

It's not really wise to do this from a Gmail account. Your recipients ISP's (or their webmail provider, be it Gmail, Yahoo or Hotmail etc) generally tend to examine emails coming from webmail pretty strictly, and trend towards reporting as spam (no matter what your intention). So it's possible the email may not reach all recipients (which really defeats the purpose of investing the time to figure out GDocs/GDrive Mail Merge) and in the worst case your Gmail account may get flagged for spammy behaviour. If you're not afraid of this, but have trouble with the GDocs/GDrive solution, Microsoft Word has a Mail Merge function that works with webmail. I've used it in the past (many years ago) and it works fine. However, the quickest, easiest and safest solution is to use Mailchimp. It has a free service that works really well - and looks really professional.

This can also be done from a free account with VerticalResponse - I don't have a basis for comparison to MailChimp, but I used to use Constant Contact and like Vertical Response better.

Google docs recently changed its name to Google Drive, so you can access it from the "Drive" link at the top of your gmail account. No downloading needed. Start there.

Thank you everybody!
