Before you can start your first campaign, you need at least one sender address. This appears as the return address on your letters and is a mandatory component of every mailing. In this article, you will learn how to create and edit sender addresses and what special considerations apply.

AutoLetter sends letters via DHL. For legal reasons, only German addresses are permitted as sender addresses. If you do not have your own German address, you can use AutoLetter's partner address.

Open the sender addresses section

Navigate to "Sender Addresses" in the sidebar. Here you will see an overview of all previously created addresses as well as KPI cards showing the total number and the number of active addresses.

Create a new address

Click the "New Sender Address" button or the plus icon to open the form for creating a new address.

Enter the name

Enter the name that should appear as the sender on the letter. This can be your company name, your personal name, or a department name.

Enter street and house number

Enter the street and house number in one field. The system automatically validates your input and alerts you to any errors.

Enter postal code

Enter the five-digit German postal code. Input is restricted to exactly 5 characters. After entering the postal code, the matching city is automatically suggested.

Select or enter the city

The city is automatically suggested after entering the postal code. You can accept the suggestion or manually enter a city. The city name must be at least 2 characters long.

Save the address

The country is automatically set to Germany and cannot be changed. Click "Save" to create the sender address. It will be immediately available for your campaigns.

Every workspace automatically comes with a fallback address: AutoLetter C/o No Border. This address has special properties:

It is preset and present in every workspace

It cannot be deleted

It serves as the sender if you have not set up your own address

You can use it as a regular sender address for your campaigns

The fallback address is especially useful if you do not yet have your own German business address or do not want to use your private address as the sender.

You can create as many sender addresses as you like. This is useful when you:

Have different locations and want to choose the appropriate sender for each

Operate different brands or business divisions

Want to send certain campaigns from a specific address

When creating a campaign, you select which sender address to use.

Edit: Click on an existing sender address to change its details. The same validation rules apply as when creating a new one.

Delete: Click the delete icon next to an address. A confirmation dialog appears to prevent accidental deletion.

A sender address cannot be deleted as long as it is being used in an active campaign. End or change the affected campaign first before removing the address.

AutoLetter processes letter delivery through DHL. Due to the legal and logistical requirements of DHL, all sender addresses must be located in Germany. International sender addresses are not accepted by the system. If you do not have a location in Germany, AutoLetter's partner address is available as an alternative.
