Preparing the message

You can now prepare your message.

First, enter a subject line for the e-mail.

Then, click Einstellungen (settings, highlighted in black) on the right-hand side of the editor.

Aussendung gestalten

A black area with entry fields appears. Here, you can define the following design features:

  • Text for the short description
  • Text for a link to browser view
  • Text for number and/or release month
  • Text for the heading 

Enter a space character if you wish to hide some of these text elements. If you simply leave the relevant entry field empty, the system will still display the placeholder text.

When you are done, click Speichern (save) in the top-right corner. By clicking Einstellungen (settings), you can collapse the black area.

Header gestalten

Now, click the text field displayed in the system.

  • Delete the placeholder text and enter the desired text.
  • If necessary, use the formatting options that the system offers. You can find the formatting icons at the top of the editor. They allow you to format the text and add buttons, horizontal lines, links, images, bullet lists and lists.
  • You can enter the following variables in the text if the relevant data are available for all recipients: {salutation} {first name} {last name} {e-mail} The variables are automatically replaced with the individual details of the recipients when you send the message.  

Click Speichern (save) in the top-right corner to finalise the text.

Text bearbeiten


Use the backspace key to remove any buttons in the placeholder text that you do not need. If this does not work, enter a blank line before and after the relevant button, highlight both blank lines and the button and then press the delete key.

Adding additional design features

In the sidebar, you can find additional text and image elements that you can use to design your message.

Select the desired element and place it in the message using drag-and-drop.

Weitere Elemente

When you hover over the top of the relevant element, 2 icons appear:

  • Cross with 4 arrows: move element
  • ×: delete element

Element verwalten

Click Bilder hochladen (upload images) and select the relevant image on your computer. Alternatively, you can also drag and drop the image into the grey area.

Bild auswählen

Once you have uploaded the image, you will see a thumbnail. To the right, you can see 3 icons:

  • Square: display image in original size
  • Pencil: edit image
  • Recycle bin: delete image

In the text fields, you can enter the following information:

  • Copyright (copyright information)
  • Title of the image
  • Text

The copyright information and the title of the image are displayed in browser view, when users hover over the image.



  • Do not tick the check box next to Bild in die Aussendung einbetten (embed image into the message) to avoid an unnecessary increase in the data volume. Images embedded in the message can slow down the delivery significantly. 
  • Recipients can only access a non-embedded image if the status of the message is Fertig zur Freigabe (ready for release) or Freigegeben (released). Therefore, never reset the status of the message to Gesperrt (locked) after sending.

To insert an image into your message, click the placeholder image in the layout element you selected.


The Bildauswahl (image selection) will open. Click the relevant image to include it in the message.


Then, click Speichern (save) in the top-right corner.

Inserting a file link

You can add a file to your message. Recipients can retrieve the file from the server with a click on the link. They can then download it and save it locally. This reduces the data volume of the message and ensures faster delivery.


Recipients can only access the file if the status of the message is Fertig zur Freigabe (ready for release) or Freigegeben (released). Therefore, never reset the status of the message to Gesperrt (locked) after sending.

Change to the tab Downloads.

Click Dateien hochladen (upload files) and select the file on your device. Alternatively, you can move the file via drag and drop to the grey field.

Datei hochladen

A download icon is shown after the upload. You can click the file name next to it, and, depending on your browser settings, a preview of the file is shown or you can download the file.
On the right side you can delete the file.


To add a file link, change back to the message.

Select the text you would like to act as a link. In the top of the editor click Einfügen (insert) and then Link.

Link einfügen

In the following pop-up activate the radio button next to Download. If you have uploaded more files, select the required file via the drop-down menu.

Then click Einfügen (insert).


Checking your message


To check a message including linked images and files, the status of the message must be Fertig für Freigabe (ready for release) or Freigegeben (released).

Once you have completed all of the steps above, you can check your message and the links one more time.

To do so, open the Versand (sending) tab and scroll down to Aussendung prüfen (check message):

  • Click Im Browser anzeigen (display in the browser) to check how your message is displayed in browser view. The browser view will open in a separate tab.
  • Enter an e-mail address and click An diese Adresse senden (send to this address). The message will be sent to this e-mail address and you can check it in the relevant inbox.

  • Dynamic channel (generated daily based on a database query): The registration/deregistration is only valid until 20:00 on the day on which you made the changes.

Optional: Selecting sending options

Monitoring the status

The time it takes to deliver all messages can vary. It depends on the number of recipients and on the number of mass e-mails sent simultaneously.

You can get a rough overview of the delivery status in the Statistik (statistics) tab under Transportstatus der E-Mails (delivery status of the e-mails). Among others, you can check how many e-mails have already been delivered as part of your mass e-mail.

Under Auslastung des Gesamtsystems (system load), you can also see how many mass e-mails the mass mailer is  processing simultaneously and how many e-mails are delivered per hour, on average.
