TO: instead of BCC:

When we use BCC to send bulk e-mail, the recipient won't be seeing other than itself in BCC. But, my question is, Is it possible to have the similiar way but in TO instead of BCC. Meaning, I send bulk of 100 but when the recipient receive it, their e-mail falls under TO and not BCC. Hope you guys understand here.

Actually, I am not spamming. The recipients are all our customer. But, we just want to look 'sincere'. Imagine the customer receive the e-mail as if we personally e-mail to them alone.

Thanks.
