Campaign

A campaign is the central sending unit in PostPal. It combines three building blocks into a measurable postcard mailing:

1. Audience - who receives the postcard (from Klaviyo or a CSV address list).
2. Design - the postcard itself (uploaded print design or created in Postcard Studio).
3. Voucher (optional) - individual, trackable attribution codes configured on the design.

Create a campaign on one form page: name → campaign type → design → audience → schedule → address check → material & finish → payment method → invoice address → start. Sections appear progressively and remain visible. Reopened drafts show all sections. Configure voucher codes beforehand on the design in Postcard Studio. After start, PostPal handles data preparation, printing, quality assurance and delivery through Deutsche Post.

A new campaign is saved as a draft as soon as you give it a name or make a selection (without a name it starts as "Unbenannte Kampagne"). While it is a draft, text fields save on blur and selections save immediately. Rename the campaign and check its save status in the breadcrumb. After start, changes require “Änderungen speichern”. For a paused campaign choose whether to keep it paused or activate it. Going back keeps the draft; delete it explicitly from the breadcrumb menu.

Important choices in the campaign flow:

• Shipping date: You choose a delivery date. PostPal calculates when data preparation, printing, quality assurance and handover to Deutsche Post need to start. For automated campaigns, you also choose the frequency: weekly, monthly or yearly. For yearly campaigns, you additionally define the desired delivery period.
• Material for classic postcard formats: For postcards such as DIN A6, DIN long or DIN Maxi, you choose 300g coated art board, 300g chromo board or 300g recycled board.
• Finishing for classic postcard formats: You choose between no finishing and one-sided matte film lamination. Finishing is optional and helps protect against light surface marks during sorting and delivery.
• DIN A4 letter: For DIN A4, there is no separate material or finishing selection in the campaign. Instead, the selected design format determines whether the letter is printed one-sided or two-sided.

A campaign requires a minimum shipment quantity of 500 recipients. Continuous campaigns keep sending automatically to newly added audience recipients, while one-time campaigns send exactly one batch.

Once all non-terminal mailings of a one-time campaign have finished tracking, PostPal marks it as Completed. This is final: the campaign can no longer be edited, reactivated or sent again.

If a configured voucher becomes unavailable after its Shopify connection is removed, the campaign remains editable. New mailings resume only after you remove voucher tracking or select an available voucher.

Design & Audiences in campaign details

The Design & Audiences card shows the linked design and each variant with its vouchers. Audiences shared by all variants appear once for the design; in Audiences pro Variante mode they appear inside their variant. Click an audience row to open its details. For CSV, the row opens the CSV file list if you have permission to view it. Any deleted audiences still shown in the card are no longer linked.

Several audiences

For Klaviyo campaigns, pick one or more audiences under Audience auswählen. With several audiences every contact receives exactly one card, the variants are distributed by the design's shares as usual. Below the picker you see the total ("bis zu …"), the calculation and the advanced settings with shipment maximum and control group — as for one audience, for all audiences together. All audiences must come from the same Klaviyo account and share one shipping destination.

Audiences per variant

For Klaviyo campaigns whose design has at least two variants with a share above 0%, you can give every variant its own audiences. Choose Audiences pro Variante under Audience auswählen.

• Assignment: every variant gets one or more Klaviyo audiences. An audience can be assigned to one variant only. To start the campaign, every variant needs at least one audience.
• Same account, same destination: all audiences of a campaign must come from the same Klaviyo account and share one shipping destination.
• Which card a contact gets: the variant of their audience. The design's shares do not apply in this mode. Test contacts still get a variant by the shares.
• Overlaps: a contact in several audiences receives exactly one card. If the audiences belong to different variants, which one is not guaranteed.
• Quantity: the minimum quantity counts every contact once. The form adds up the audiences' last counts and therefore shows an upper bound ("bis zu …").
• Control group and shipment maximum: you set both as for one audience, in the advanced settings below the variants; they apply to the whole campaign.
• New variant in the design: if the design later gets another variant with a share, it receives no cards until you assign it an audience in the campaign. The campaign page points this out.

Design and payment in the same form

Search existing designs and see their formats and unavailable reasons. Create a design in Postcard Studio from a campaign draft: the draft saves before leaving, and successful design saving returns with the new design selected. Cancelling keeps the previous design and configuration. Common audiences survive a design change. Assignments to former design variants are removed only after a confirmed warning; new variants need new assignments.

Payment methods and discounts come from the published price list. Previously saved methods that are no longer offered remain visible and need replacing before saving. Payment applies to this campaign; final saving also makes the invoice address the account default. Draft saves do not change account defaults. The estimate uses destination and quantity. Without a planned date, it uses current tariffs without a seasonal surcharge. Selecting a date recalculates the costs with the applicable seasonal surcharge. Starting a campaign still requires a valid planned date. Multiple audiences may overlap, so their forecast is an upper bound. Unknown counts do not produce a fabricated price.
