SmarterMail Help


This settings page is only available to Domain Administrators, Mailing List Administrators and System Admininstrators with the proper permissions.

To view the mailing lists for a specific domain, click the Settings tab, then click Mailing Lists in the navigation pane.

This page consists of a number of tabs, and each tab has its own page:

  • Options - The configuration options for an individual mailing list.
  • Subscribers and Digest Subscribers - Add subscribers who will receive the standard mailing list postings or digest emails.
  • Posters - Whitelist email addresses or domains who can post to the mailing list
  • Banned Users - Prevent specific email addresses or domains from posting to the mailing list
  • Messages - Configure the header and footer for postings as well as the replies sent to listserv commands
  • Custom Fields - Customize list postings with subscriber custom fields

Creating a New Mailing List

To create a new mailing list, click the New button in the content pane toolbar. You can also edit an existing mailing list by clicking on it. When you click the New button, a modal window opens with the following fields:

  • List Address - This is the address that will be used for the address. A List Address is simliar to a new Account address: it simply needs to be whatever will be appended to the left of the domain name. For example, "MarketingNewsletter".
  • List Administrator - This is the existing Account that will act as the administrator of the list. Select a user from the drop down.

Once the new list is created, its options will open, where you can edit the list as needed. These cards and options are discussed below.

Options Tab


  • Name - Essentially, the "username" for the mailing list. SmarterMail will use the name to create the actual email address that will be associated with the mailing list.
  • Status - New mailing lists default to a status of Enabled. To temporarily prevent postings to this list, change the status to Disabled.
  • List Admininstrator - The "owner" of the mailing list. This person will actively manage the mailing list, posts to the list and any replies. The moderator must be an active email user for the domain.
  • Show in Global Address List - There are times when you may want a mailing list to show up in the Global Address List so that all of your subscribers can send to it. If that's the case, enable this setting.
  • Description - A brief summary of the mailing list.

Message Options

  • List To Address - The email address that will display in the To field when a subscriber receives a mailing list message. Setting this to List Address means that the email address associated with the list will display as the To: address when recipients receive the message.
  • List From Address - The email address that will display in the From field when a subscriber receives a mailing list message. By default this is set to List Address.
  • List Reply To Address - The email address that will display in the Reply To field when a subscriber receives a mailing list message. When a subscriber hits 'Reply' to the message, this address will receive the reply. If a subscriber hits 'Reply All' all list recipients will receive the reply. By default this is set to List Address
  • Text to show in unsubscribe link - The text entered here will be hyperlinked when using the Unsubscribe variable. If this field is left blank, the unsubscribe link will hyperlink the full URL.
  • Webmail URL - The URL for the SmarterMail login page. This setting can be used to override the server's configured hostname for mailing list communications.Note: URLs should include the https:// prefix. For example:
  • Send Subscribe Email - Select this option to automatically send an email to new subscribers confirming their subscription to the list. Note: This is not an opt-in message, only a confirmation email.
  • Send Unsubscribe Email - Select this option to automatically send an email response to unsubscribe requests.
  • Enable Double Opt-In - Select this option to automatically send an email to new subscribers that requires them to confirm that they are subscribing to the list by clicking on an activation link. Using double opt-in is a good way to confirm subscriptions to the list and to help reduce abuse complaints.
  • Disable List Error Replies - Select this option to prevent the system from automatically replying to incorrect listserv commands.


  • Password - To restrict people from sending emails to a mailing list, type a password in this field. Note: To send emails to a mailing list that is password protected, you must add the password to the beginning of the subject line of the email, enclosed by brackets and colons. For example, if "password" is entered into this field, the subject line of the email would need to begin with [:password:].
  • Allowed Posters - An email that is sent to the mailing list (and therefore to its subscribers) is considered to be "posted." Use this field to specify who has access to post to the list. Note: Email addresses specified on the Posters tab will override this field.
    • Anyone - Anyone can email the list, regardless of whether they are subscribed to the list or not. In turn, this sends an email to all members. Note: This setting can cause abuse if it is not closely monitored. Therefore, it is recommended to restrict the allowed posters to 'subcribers only', at the very least. For larger lists, allowing Moderator Only is a better idea and will cause less issues.
    • Subscribers Only - Allows the list subscribers, and only the list subscribers, to send and receive posts. The moderator will still be permitted to post. This can cause abuse issues as well if you have an active list, so using Subscribers Only should only be used for smaller lists or for digest mode only.
    • List Administrators Only - The List Administrator(s) is/are the only one(s) who can post to the list. This means that no one else, not even list subscribers, will be able to post.
  • Subject Prefix - The optional text that will appear in the subject line. SmarterTools recommends using a subject prefix for discussion lists to help subscribers easily filter through posts. For example, add a "List- " or "Discussion -" prefix so that users know that the message is posted to an email list. Recipients can then create filters to move those messages to a specific folder or manage them in some other way.


  • Enable SUBSCRIBE Command - Select this option to allow people to subscribe to the mailing list by emailing a listserv command to the command address. For more information, refer to Listserv Commands. Note: If this option is disabled, only list administrators can add new subscribers to the mailing list.
  • Enable LIST Command - Select this option to allow people to receive a list of the mailing list subscribers by emailing a listerv command to the command address. For more information, refer to Listserv Commands. Note: It is recommended that you leave this option disabled, as people or automated systems could use the user list for malicious purposes.


Throttling limits the number of messages sent per hour and/or the amount of bandwidth used per hour to send messages. Domain Administrators can use this feature to ensure a mailing list does not send out massive amounts of email through out the day, thereby possibly getting the domain blacklisted.

  • Outbound Messages per Hour - The number of messages sent by the mailing list per hour. By default, the number of outgoing messages is 500.
  • Message Throttling Action - When using either message or bandwidth throttling, adminstrators can select an action for SmarterMail to take once the particular throttling level is reached. Domain Administrators can elect to do nothing at all, or they can either Delay or Reject messages until the amount of mail being sent falls beneath the throttling limit that is set. By default, mailing lists are set to Delay messages once the threshold has been reached.
  • Outbound Bandwidth MB per Hour - The total number of MBs sent by the mailing list per hour. By default, the outgoing bandwidth is 50MB.
  • Bandwidth Throttling

Digest Settings

To reduce the number of emails mailing list subscribers receive, domain administrators can allow subscribers to sign up for digest mode or normal mode. Essentially, digest mode condenses all the messages sent to the list into a single email that is sent to subscribers on a monthly, biweekly, weekly, daily, or other defined basis. This is especially useful for very active lists or lists with a larger number of subscribers.

  • Enable digest mode - Enable this setting to view and modify the remaining Digest settings.
  • Subject - The subject line for the digest email.
  • Trigger Type - The frequency of the digest emails: Daily, Weekly, Biweekly, Monthly or Manual. If Manual is selected, digest emails will only be sent when using the Send Digest button.
  • Digest Format - The format (HTML, text, etc.) in which digest emails are sent.
  • Disable non-text attachments in digest - Select this option to remove non-text attachments from the digest email.
  • Send Digest - Allows an administrator the ability to send the Digest manually.
