I would like to send to a mailing list without sending email addresses that is on the mailing list.

I would like to send to a mailing list without sending email addresses that is on the mailing list.

Chosen solution

Two options:

1) Use Bcc ("blind carbon copy"). This sends a a single copy to a server, which then strips out the Bcc'd addresses and sends on a copy to each Bcc addressee. The recipient will (usually!*) see only whatever was put into the To or Cc boxes. If you left these empty, Thunderbird inserts

"To: undisclosed recipients;". 

You could create an address or alias to put into the To box as a means of identifying what the mailing is about. Some servers refuse to process messages with no To: address, hence the automated filling of it when the user leaves it empty.

(*) The "usually" is there because a few smtp servers do not interpret Bcc as I described here, and show Bcc addresses to all Bcc recipients. You need to check how your email provider supports Bcc. This is best done by sending test messages to yourself or to a friend or colleague you can trust.

2) Use a Mail Merge, which generates a discrete email message per addressee, optionally personalised with items such as name, date of birth, mailing address etc - think "Readers' Digest" and their "you have been selected…" circulars.

Thunderbird has a Mail Merge add-on. Your office productivity suite might have its own tools for doing this.

An alternative to (2) is a commercial service which provides bulk mailing, such as mailchimp.
