Catalog Object Limits Marketing Cloud Personalization imposes limits per dataset for catalog objects and attributes. For more information, see [Catalog Objects](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_catalog_object.htm&release=264.0.0&type=5 "Catalog objects and their relationships define the structure of your catalog. Personalization uses catalog objects to interpret and understand customer engagement and affinities. Examples of catalog objects include products, articles, blog posts, categories, brands, styles, and features. Personalization includes several built-in catalog objects, and you can create custom ones to meet your specific needs.").

Number of	Limit	Description
Active items per catalog object type	2 million	An active item is one that's eligible for recommendations. Examples: 2 million products, 2 million brands, 2 million articles, or 2 million blog posts
Total items across all catalog object types	10 million	This limit is the total for all catalog objects.
Custom catalog object types	25	This limit is for user-created catalog object types. This limit doesn’t count the built-in catalog objects (Product, Blog, Article, Promotions, and Category). Examples: brand, style, tags, keywords, author, color
Attributes for a catalog object (built-in attributes + user-created attributes) This limit includes the following built-in attributes, which differ slightly for some of the built-in catalog objects:	35
products	16	Product built-in attributes: (id, name, url, description, published, expiration, rating, numRatings, imageUrl, promotable, price, listPrice, priceDescription, currency, inventoryCount, margin)
blogs	10	Blog posts built-in attributes: (id, name, url, description, published, expiration, rating, numRatings, imageUrl, promotable)
articles	10	Article built-in attributes: (id, name, url, description, published, expiration, rating, numRatings, imageUrl, promotable)
custom catalog objects	10	User-created catalog object built-in attributes: (id, name, url, description, published, expiration, rating, numRatings, imageUrl, promotable)
Related catalog object values for a single item	50	You can store up to 2 million of each catalog object type. When you create a catalog object relationship, you can store up to 50 values on the item. Example: Suppose your primary catalog object is a hotel that has a related catalog object named Amenity (representing amenities such as free wifi, a pool, a gym, room service, or a bar). You can assign up to 50 amenity tags to that related catalog object. You can have more than 50 amenity values stored in Marketing Cloud Personalization (up to 2 million), but only 50 of those values can be stored against a single item.
Category values for a single item	15	Personalization automatically applies the category object as a related catalog object to the built-in objects (products, blogs, articles). Example: A hierarchy (such as Men’s\|Clothing\|Tops\|Shirts) is a single category value.

Promotion and Asset Limits Marketing Cloud Personalization specifies limits per dataset for promotions, segments, and assets. For more information, see [Campaign Promotions](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_promotion.htm&release=264.0.0&type=5 "Offer your customers special deals or advertise specific products with campaign promotions in Marketing Cloud Personalization. A promotion is an image that encourages customers to click through for more details. You can deploy promotion images on a web page or in an email, including call-to-action messages or incentives to engage customers and achieve specific business goals. You can also use promotions with Einstein Decisions for rule-based decisions and machine learning to target customers in multiple channels.").

Number of	Limit	Description
Active promotions	10,000	An active promotion is one that's eligible for a campaign to return.
Promotions returned for review and ranking	50	If a user is eligible for more than 50 promotions, Personalization selects a random set of 50 eligible promotions to return.
User attribute match criteria	5	—
Segment inclusion	10	—
Segment exclusion	10	—
Attributes for a promotion	35	Promotion built-in attributes: 10. You can add up to 25 user-created attributes.
Related catalog objects	20	—
Related catalog object values for a single item	50	—
Assets for a promotion	10	—
Assets assigned to a single content zone or tag	1,000	Applies across all promotions that share the content zone or tag. Example: If you have a content zone or tag called "Winter Savings," then you can have up to 1,000 assets across all promotions that share the “Winter Savings” content zone or tag. If you have over 1,000 assets that share a content zone or tag, Personalization selects a random set of 1,000 for decisioning purposes.

User Attribute Limits Marketing Cloud Personalization has a limit of 100 user attributes per dataset. User Profile Object and Account Profile Attribute Limits Marketing Cloud Personalization imposes limits per dataset for user profile objects and account profile attributes. For more information, see [User Profile Objects](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_user_profile_object.htm&release=264.0.0&type=5 "Gain a deeper understanding of your users by creating user profile objects.").

Number of	Limit	Description
User profile object types	10	Disabled user profile objects count toward this limit. The same is true for catalog objects. Examples: Lease, machine registration, mortgage
Attributes for a user profile object	10	Example: If your user profile object is a mortgage, its attributes can include customer-specific information, such as start date, end date, and APR.
Related catalog objects for a user profile object	5	Example: If your user profile object is a lease for a vehicle, you can assign it related catalog objects, such as make, model, and year.
Values per related catalog object for a user profile object	5	Example: If your user profile object is a credit card and you assign it a related catalog object of rewards, associated values can include cash back, travel rewards, and no ATM fees.
User profile objects per profile object type per user	100	Example: Suppose you’ve configured three profile objects: Lease, Ownership, and Service Case. Each user profile can have up to 100 objects of each type: up to 100 Lease objects, up to 100 Ownership objects, and up to 100 Service Case objects.
Account profile attributes	100	Example: Account name, Account ID, Account domain, Employee count. Firmographic data that gives you a more in-depth profile of each account.
Maximum distinct actions per profile per day	100	Personalization tracks the number of distinct actions that a user takes on a website. For example, suppose a user visits the homepage 20 times, views the Product Detail Page 11 times, updates their billing information one time, and checks out twice. In this example, Personalization tracks four distinct actions for that user. The action limit applies to the number of distinct actions per user, not to the number of times a user performed a particular action. If the user exceeds the limit of distinct actions (say, 101 distinct actions over a 24-hour period), then Personalization truncates one of the distinct actions it’s tracking to keep the total within the limit. Personalization drops the action with the fewest occurrences. For example, the user updated their billing information only once. For an individual user, dropping a distinct action can affect segment membership. For more information on actions, see Item Actions and Actions in the developer documentation.
Maximum distinct actions per profile, all time	1,000	Example: If a user exceeds 1,000 distinct actions, Personalization truncates one of the actions it’s tracking to keep the total within the limit. For more information, see the example (in the previous row) for the maximum distinct actions per profile per day.
Maximum line items in a cart	100	The total number of line items stored in a cart for a single user.

Identity Management Marketing Cloud Personalization imposes limits for identity types. For more information, see [Identity Types and Attributes](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_identity_type_attributes.htm&release=264.0.0&type=5 "Personalization’s identity system uses deterministic matching to create a Unified Customer Profile for each of your customers. Specific identifiers, called identity types, determine how to process web events, API events, and channel events to identify users from various sources. Personalization includes several built-in identity types, such as email address and customer ID. If the built-in identity types don’t meet the needs of your organization, you can create additional identity types."). | Number of | Limit | Description | | --- | --- | --- | | Additional identity types | 3 | If the built-in identity types are insufficient, you can create a maximum of 3 additional identity types. | Mobile App Limits Marketing Cloud Personalization limits the number of mobile apps per dataset. | Number of | Limit | Description | | --- | --- | --- | | Mobile apps per dataset | 18 | Each dataset supports a built-in default website plus up to 18 mobile apps. Deleted apps still count toward the limit, so deleting an app doesn't free its slot. When you reach the limit, create a new dataset. | ## Integrations Limits There are limits on ETL integrations, the integration with Salesforce CRM, and the automated data sent to Personalization through Flows. For more information, see [Integrate with Other Products](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_integration.htm&release=264.0.0&type=5 "Exchange data between Marketing Cloud Personalization and other systems, including other Salesforce products."). ETL Integrations There are limits to some attributes and associations per item. Exceeding these limits causes a record to fail. | Number of | Limit | | --- | --- | | Line items per order | 1,000 | | User attributes per user feed | 50 | | Attributes per catalog object type | 35 | There’s no enforced file-size limit, but Salesforce recommends keeping files under 5 GB. Individual customer ingestion speeds can vary based on a number of factors, including: - Number of users in the dataset - Time of day when an ETL job is started (other ETLs are running at the same time) - Number of user attributes in the feed and size of attribute values (for example, the length of strings) - Size of files being run (number of attributes in the file) - Size of user profile documents, including visit history, number of attributes, attribute change history, and daily stats. Customers can export up to 10 million users per day per dataset. For more information, see [Marketing Cloud Personalization Editions](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_editions.htm&release=264.0.0&type=5 "Marketing Cloud Personalization comes in two editions: Growth and Premium."). Integrate Personalization with Salesforce CRM For more information, see [Integrate Marketing Cloud Personalization with Salesforce CRM](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_salesforce_crm.htm&release=264.0.0&type=5 "Share data between Marketing Cloud Personalization and Salesforce CRM. Send Personalization user and visitor information to Salesforce CRM. Receive CRM data associated with text fields, dropdown menus, numeric values, or segments."). | Number of | Limit | Description | | --- | --- | --- | | Salesforce CRM pull limit of records | 4,500,000 | Limit per job or manual execution. | | Salesforce CRM push limit of records | 750,000 | Limit per job or manual execution. | Automate Data Sent for Personalization Using Flows For more information, see [Automate Data Sent for Personalization Using Flows](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_salesforce_sales_service_cloud_mgd_pkg_automate_data_w_flows.htm&release=264.0.0&type=5 "Automatically send data that is specific to a Named Individual Profile from Sales or Service Cloud to Personalization."). | Number of | Limit | | --- | --- | | Maximum number of records that the Personalization Apex Action can process | 100 | ![Note](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_personalization-264-0-0-production-enus/16bf1f60-f44c-4260-a56e-f052cfe515a3/images/icon_note.png) Note Apex Execution Governors and Limits restricts the total number of callouts (HTTP requests or web services calls) in a transaction to 100. You can increase the batch size from the default of 25 to 100 with the removal of runtime validation for datasets, attributes, and profile objects. For more information, see [Execution Governors and Limits](https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_gov_limits.htm). ## File Retention Limits Files in all directories are automatically deleted after their retention period expires. | File Type | Retention Period | | --- | --- | | SFTP files | 60 days | | Data 360 files | 30 days | ## Segment Management Limits Marketing Cloud Personalization provides the limits associated with segment membership. For more information, see [Define Segments for Marketing Cloud Personalization](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_segment.htm&release=264.0.0&type=5 "Audiences are the specific individuals, referred to as users, or accounts, such as companies and organizations, that qualify to be members of a segment. You can create segments to group audiences according to a set of criteria that you define."). | Number of | Limit | | --- | --- | | Manual segments per dataset | 1,000 | | Enabled rule-based segments per dataset | 500 | | Members per segment to qualify for daily email reports | 10,000 | ## Event Limits Marketing Cloud Personalization imposes a limit on the total rate of event traffic across an entire Personalization account. This limit is in addition to limits stated in the Channels and Campaigns Limits section and applies to aggregate activity across all channels and users. An event is a description of a single interaction by a single user at a point in time. It's delivered in an HTTP request sent to any real-time event processing endpoint. Examples of interactions that events can describe include page views, campaign impressions, clicks, purchases, and adding items to carts. | Number of | Limit | | --- | --- | | Events per Personalization account per minute | 400,000 | ## Channels and Campaigns Limits Marketing Cloud Personalization provides limits specific to Web Campaigns, Mobile Campaigns, and Triggered Campaigns. For more information, see [Channels and Campaigns](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_channel_campaign.htm&release=264.0.0&type=5 "In Personalization, channels are the various digital touch points you use to interact and engage with your customers and leads. Campaigns are the heart of providing personalized experiences within each of those channels. Depending on your Marketing Cloud Personalization license, you have access to develop campaigns for channels such as web, email, mobile, and third-party integrations."). Web Campaigns You can create up to 10,000 web campaigns per dataset. The Web SDK automatically blocks events if: - More than 10 events have been sent for the same user in the last 5 seconds, or - More than 5 events with the same interaction name (Action) have been sent for the user in the last 2 seconds. In addition to the above limits, the Web SDK enforces these limits for ping, error, and campaign statistics events. - Ping events are limited to 10 events sent every 5 seconds. - Error events are limited to 10 events sent every 5 seconds. - Campaign statistics events are limited to 10 events sent every 5 seconds or 5 events with the same experience ID sent every 2 seconds. Mobile Campaigns The Personalization Mobile SDK supports up to 50 events per second. Up to 1,000 events can be queued when: - The device isn’t connected to the internet, or - The Mobile SDK is waiting for a response to the previous event. Triggered Campaigns Salesforce limits the number of triggers based on your contracted number of named individual profiles. Each named individual profile gets four triggers per month, calculated as an hourly rate. For example, using the base allotment of 100,000 named individual profiles, the per-profile rate is approximately 555 triggers per hour: ``` (Named individual profiles × 4) / 30 days / 24 hours = 555 triggers/hour ``` ![Important](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_personalization-264-0-0-production-enus/16bf1f60-f44c-4260-a56e-f052cfe515a3/images/icon_important.png) Important Exceeding this rate delays messages. If the rate stays high for multiple hours, messages can drop. When configuring a triggered campaign template, keep in mind that strings can’t exceed 4,096 characters. Survey Limits Marketing Cloud Personalization has limits for survey attributes. You can have up to 10 total survey attributes per dataset. For more information, see [Use Surveys in Web Campaigns](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_survey.htm&release=264.0.0&type=5 "Use surveys to design, test, and deploy questions to your visitors and customers to gather feedback in web campaigns."). Open Time Email Campaign Limits For more information, see [Open Time Email Campaigns](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_email_campaign.htm&release=264.0.0&type=5 "Use open time email campaigns to deliver personalized content and product recommendations each time a recipient opens an email. Using existing email campaigns that you send using your mail marketing service, Open Time Email campaigns deliver real-time personalized content to each member of your subscriber list.").

Number of	Limit	Description
Item templates that can be published	16	—
Item template sync error rate per job	10%	If the error rate for an image generation job exceeds 10%, the item template can’t be published.

Third-party Campaigns You can have a maximum of 900 third-party campaigns. For more information, see [About Integrating with Third-Party Solutions](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_third_party_integration_about.htm&release=264.0.0&type=5 "Marketing Cloud Personalization integrates with a variety of third-party solutions (external to Salesforce). Integration options include data management platforms, email service providers, third-party campaign detection products, analytics products, content management systems, social media, and tag managers."). ## Machine Learning Limits Marketing Cloud Personalization provides limits associated with Einstein Decisions and Einstein Recipes. For more information, see [AI-Powered Personalization](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_machine_learning.htm&release=264.0.0&type=5 "Marketing Cloud Personalization uses advanced machine learning algorithms to capture a deep understanding of your business and your users. Einstein Recipes and Einstein Decisions use those algorithms to present personalized recommendations and offer the most relevant experiences to your users in real time."). Einstein Decisions Limits Marketing Cloud Personalization has limits for the various Einstein Decisions features. For more information, see [Einstein Decisions](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_einstein_decision.htm&release=264.0.0&type=5 "When a user views a promotion on your website, Marketing Cloud Personalization captures the user's context—including whether they’re a returning visitor, the device they’re using, and other information that provides insight into that user. Einstein Decisions, Personalization’s machine learning approach for next-best-offer decisioning, uses that context to predict the value of showing a specific offer to a particular user.").

Number of	Limit	Description
Features	200	You can configure up to 200 features on the feature engineering page.
Offers for promotion and ranking (real-time offers)	50	Personalization limits Einstein Decisions to evaluating up to 50 offers for its promotion analysis and ranking. If a user is eligible for more than 50 offers, Personalization selects a randomized set of the eligible offers for analysis.
Promotions in a Campaign Response	12	A campaign using Einstein Decisions can return up to 12 promotions in a response.

Einstein Recipes Limits Marketing Cloud Personalization has limits for the various Einstein Recipes features. For more information, see [Einstein Recipes](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_einstein_recipe.htm&release=264.0.0&type=5 "Einstein Recipes are Personalization's machine learning algorithms. With Einstein Recipes, you can create configurable algorithmic strategies to present each customer with customized product and content recommendations throughout your various channels. You can use Einstein Recipes to support specific scenarios, such as cross-sells, content promotions, and trending products."). - Test groups can contain up to 20 customers. - You can have up to 15 test groups, including the sample test group. - Each dataset can have up to 500 recipes. ## Reports and Analytics Limits Marketing Cloud Personalization provides limits associated with Actions Reports and Data Warehouse. For more information, see [Marketing Cloud Personalization Reports and Analytics](https://help.salesforce.com/s/articleView?id=mktg.mc_pers_report_analytics.htm&release=264.0.0&type=5 "After personalizing your site, use Personalization reports to determine what’s working and where to make improvements."). Actions Report Marketing Cloud Personalization supports a few thousand unique actions per dataset. More than that can cause problems across the Personalization platform. Capture an action only if you need it for personalization and targeting. Personalization isn’t an analytical store, so don’t push every action into Personalization from a tool like Google Analytics. Use the sitemap as a filter. It’s where you decide which actions are worth ingesting. Data Warehouse Limits ![Note](https://sf-zdocs-cdn-prod.zoominsoftware.com/tdta-mktg-mc_personalization-264-0-0-production-enus/16bf1f60-f44c-4260-a56e-f052cfe515a3/images/icon_note.png) Note The Data Warehouse is available only for customers who have already purchased the Marketing Cloud Personalization - Data Warehouse add-on product. Marketing Cloud Personalization Data Warehouse supports these limits:
