The innovative List+ feature allows you to easily send an email from any program (e.g. Outlook, Gmail, Yahoo! Mail, etc.) to multiple recipients, leveraging the MailUp system. Say "good-bye" to the old idea of distribution lists, and "hello" to the smart email addresses that you can leverage through MailUp's new List+ feature.


  • Easily create a group of colleagues and send a message to them
  • Send a personal note to all your customers, right from your favorite email client, without having to log into Mailup
  • Forward interesting news articles to the marketing team
  • Send quick updates to the sales team
  • Mail updated pricing information to your resellers

Using List+


Log into the MailUp console and select Settings > List settings > List+. You will find a button to enable the feature.

Authorizing senders

In order to be able to use List+, you need to add the email address that you will be sending messages from to the list of authorized senders.

Click on the corresponding button to add a new sender, and enter the email address that  you you are authorizing.


titleAuthorized sender and message sender
Please note that the sender(s) that you authorize here will NOT be the actual sender of the message. The sender of the message will be the default Send Email and Send Name specified for the List.

The same address will be used by MailUp to authorize a new List+ mailing, unless an alternative address is specified.

The reason why you have the ability to specify a separate address for mailing authorizations is that you may be sending the message from an application - which uses a certain email as the sender - but may want another person to authorize the mailing.

Although the system allows you to turn off the required mailing authorization, we strongly recommend that you do not do so. If you do, there is the possibility of messages being sent to a potentially large number of recipients without authorization. For instance, think of a virus infection that may affect the computer from which List+ messages are sent.

How a List+ mailing works

Using List+ is extremely easy. Log into your MailUp admin console and select Settings > List settings > List+


titleImportant notes about List+ mailings

Please note the following:

  • If you are sending a message to a List+ address, and you are also including other email addresses in the TO field, make sure that the List+ address is first, or MailUp will not be able to handle the request.
  • If there are other messages already in the queue, the List+ message will be queued up

Sending a message to an entire list

Log into your MailUp admin console and select Settings > List settings > List+


  • Each MailUp account has a different console_ID
  • Each List within that console_ID has a different ID
  • The security_code changes is also unique. For extra security it is recommended to change it every 90 days by clicking on the Change security code button.

Sending a message to one or more groups

Log into your MailUp admin console and select Settings > List settings > List+


You can find the Group ID either in the page that lists all Groups under the Recipients menu, or in the Codes Table under Settings > Account settings > Developer's corner

Sending a test message

You can send a test message to the authorized sender, to preview how the message will look. To do so, use the address: 


Saving a message in MailUp

You can also use List+ to save a message into your MailUp console. This is useful if you created the message elsewhere. To do so, use the address:


  • View the HTML message in your browser
  • Select all (CTRL+A)
  • Copy (CTRL+C)
  • Paste into a new, empty message in your email editor
  • Send it to your MailUp account using the List+ address mentioned above


In the Alerts center you can view and modify the alerts that pertain to the List+ feature.
