Repeatable product blocks enable you to add multiple products dynamically to your email campaign from different product sources, such as Interactions events or more advanced recommendation sources.

To edit a repeatable product block in your existing email campaign, proceed as follows:

1. Go to Channels > Email Campaigns, select your campaign, then click Edit.

2. Go to the Content Creation step in the bottom menu and

- select an existing repeatable product block, or

- drag and drop one to the campaign.

4. In the Product Source Settings pop-up window tick the Personalization rule radio button and select the  rule you want to use from the drop-down list, then click OK.

4.b Optionally, you can select the Product set radio button to set a pre-configured use case (i.e. either Price drop, Back in stock or Low in stock).

5. At the Display Settings section set the minimum and maximum number of products that should appear in the email.

6. Click Save to save your email.

After specifying the Personalization rule as a data source of your repeatable product block, you can start adding the personalization fields to your block.

1. Position the cursor where you want to add the Personalization token, click the Personalization icon in the toolbar.
2. You can select any of the following product catalogue fields:

a. Personalizing Title or Price fields: Highlight the Title or Price placeholder and click Personalization icon. Select the Title or Price token under Product Catalog.

b. Personalizing image: Click the Image placeholder and select the Image Properties icon.
Select the Image token under Product Catalog.

c. Personalizing image link URL: Click the Personalization icon next to the Url field and select the Image Link token under Product Catalog.

3. At this point your Repeatable block is blank but do not worry, it will contain all the right product images, titles, links and prices when your campaign will be sent.

For using the same Personalization rule multiple times within a single Email campaign:

• create as many copies of the same Personalization rule,
• use subsequently the rules for each corresponding block within the campaign.

This way it reduces the probability of any unexpected behaviors during campaign generation. This prevents any errors from occurring during the generation of the campaign.

To send your email campaigns to multiple markets it is necessary to display your product details (title, price, etc.) according to the local language, currency.

Product information with localized fields in the Product Catalog can be inserted with the use of ESL codes. Learn more: Emarsys Scripting Language. You can enter the ESL codes manually for the localized product fields.

Example
As an example we take a website that serves the German language market. The English version of the product titles and category names are already part of your default product catalog, now we add the German fields.

The localized fields are as follows:
- Item: {{ item['title_de'] }} - Price: {{ item['price_de'] }} - URL to link the CTA button and image: {{ item['link_de'] }}

The image URL can be used as a personalization token, since the product image stays the same.

As Contact Preview supports Personalization Rules, you can check your recommendation results on contact level.

In case of applying the Personalization rules the displayed preview of the items is based on your preset rule filters.

In each case, the contact preview shows the top products, which means the most popular products including the most-viewed and most-purchased items, which are the Global popularity fallback, that matches your filtering.

Make all the required changes to your campaign, then click Save.
Once your campaign is ready, replace the original email campaign with your updated campaign.
