Before you reinvent the wheel, you should look into using a mailing list
manager, Mailman for example:

Regardless, confirmed double-opt-in should be a requirement as should a
mechanism for subscribers to unsubscribe themselves.

Using a 'list address' as the from address and using bcc addressing will
prevent your recipients from being able to see all the other recipient
addresses.
