Hello, 

The Sender address can be adjusted in the Mailing List settings (List From Address)

~Tony

Thanks for the reply Tony, but i don't think this is quite what i am looking for.

For instance, when i send out a letter to our mailing list, right now the email clients will show "noreply@miramar.ca", because we are currently using the Poster Address. what i'm hoping to accomplish to to show a name similar to other emails, which generally show up as "Miramar Design Studio <noreply@miramar.ca>" i tried sending with that format in the past, but never had any success getting it send correctly.

Like this?

What I did here was to change the "Display Name" of the poster. 

ok, that definitely works in most cases, i'm assuming there is no way to change this when sending eh? for instance, we do a mailing list for a restaurant, and they send out coupons every 2 weeks. They all use 1 domain name for emails, but we'd like to customize the display name per store when sending (Lake Street Coupons ...  1st Avenue Coupons) not the worst if this is not an options, just would be nice.

and Thank you very much for pointing out the display name, we completely missed that as we didn't think it was related to mailing lists, we were to focused on trying to get per email custom display names.

Richard, 

Depending on how you are sending out, you could adjust the Display Name on the fly before sending out the message. This may lead to mistakes in the future if you forget to change it and end up sending it with the wrong Display Name. 

I don't know if that's a feature that can be requested in the future? but for now, could i use the edit contact API to change the display name of the account before sending out items to the mailing list? everything we are doing with mailing lists at this point is done through API's (minus the actual sending).

Thanks
