Email to Distribution List

I am using email step in deployment process. I want to send to a DL (Distribution list). I put the distribution list name in the To field, but it is not working. I put all the email list in the variable with comma separated and the variable in the To field, did not work either. In both cases I am getting the following error.
The specified string is not in the form required for an e-mail address.

Any idea? please note the DL starts with #. e.g. #Release Group

Hi @endashaw.adane,

Thanks for reaching out.

You actually can’t send out to a distribution list. Your options would be to put all of the emails in a comma-separated format in the To field, like,,
Or, to do the same in a variable. Your #Release Group is likely causing the issue as it has to only be the email addresses.

Alternatively, you could choose to email an Octopus Team, which you could setup to be the same addresses as the Distribution List.

Please let me know if that helps.
