Date of Release: 3/23/26

Update: Interest targeting now includes a redesigned discovery experience with a guided entry page, faster, more flexible search, and advanced filtering. Advertisers can explore available segments without needing exact names, then refine results using faceted filters to quickly find the most relevant audiences.

Why it matters: This update makes it easier to discover and select the right audiences with confidence. By removing the need for precise search terms and adding better filtering tools, advertisers can build interest-based audiences more efficiently, reduce guesswork, and move through campaign setup faster.

Date of Release: 3/13/26

Update: Data uploads are now more transparent and reliable across CRM, Geo, and Offline Attribution lists. The updated upload experience provides clearer validation, downloadable error reports, and row-level feedback so advertisers can quickly understand which records were accepted or rejected. These improvements also introduce threshold-based safeguards and data validation checks to prevent issues like invalid rows, formatting errors, or mismatched data types from silently impacting your audience lists.

Why it matters: These updates make audience uploads more predictable, explainable, and safer at scale. Advertisers can now clearly reconcile what happened during an upload (records submitted, accepted, and rejected) and resolve issues directly using the downloadable error report. The result is faster troubleshooting, fewer escalations, and greater confidence that your audience data is processed correctly before campaigns begin targeting.

Date of Release: 3/12/26

Update: Creative uploads now support multi-file uploads, real-time progress tracking, and a persistent upload status indicator, allowing you to monitor upload progress while continuing to navigate the platform. This creates a more flexible and uninterrupted workflow during campaign setup.

Why it matters: These improvements make uploading creatives faster and more reliable by reducing bottlenecks and giving clear visibility into upload progress. You can continue working without waiting for uploads to complete, resulting in a smoother setup experience and faster time to launch.

Date of Release: 3/6/26

Update: MNTN API 3.0 delivers a faster, more flexible reporting experience with multidimensional querying, simplified API definitions, and First Touch reporting by default, while still supporting Last Touch metrics. API 3.0 now includes full data parity, including support for Audience Segment Data, making it the complete replacement for legacy API usage.

Why it matters: API 3.0 provides a more scalable and performant way to retrieve MNTN reporting data, giving advertisers deeper visibility into campaign performance and more flexibility in how they query and analyze results. As part of this transition, API 1.0 will be deprecated on April 1, 2026. Customers currently using the legacy endpoint will need to upgrade to API 3.0 to continue receiving reporting data.

Date of Release: 3/2/26

Update: Advertisers can now manage Account-Level Audience Exclusions, giving them a centralized way to block recent site visitors and converters from seeing their commercials in prospecting campaigns. With configurable lookback windows from 30 to 365 days, advertisers can define what “new-to-brand” means based on their own first-party data. Once enabled, these exclusions automatically apply across all prospecting campaigns to ensure consistent targeting.

Why it matters: Account-Level Audience Exclusions help advertisers focus spend on net-new customer acquisition instead of existing customers. By centralizing exclusion settings and allowing flexible look back windows, this feature gives marketers greater control over prospecting strategy. It also improves transparency, with all exclusion changes logged in the Activity Timeline for clear visibility.

Date of Release: 2/26/26

Update: The Sales Cycle metric helps advertisers understand the average number of days between a user's first site visit and their first conversion, regardless of MNTN impact. Available in the Attribution section of My Account, the Sales Cycle metric uses data collected from your MNTN tracking and conversion pixels to calculate your average days to conversion.

Why it matters: The Sales Cycle metric gives advertisers a reliable benchmark for evaluating campaign performance. When launching a new campaign or making adjustments like adding budget, changing audience segments, or adding new creative, use your Sales Cycle as a guide for how long to wait before drawing conclusions. This helps your avoid premature optimization and gives your campaigns enough time to show meaningful results.

Date of Release: 2/17/26

Update: Frequency Controls give advertisers the option to control how often households see their commercials within a defined time period. This feature allows marketers to set separate caps for two audience groups during prospecting campaigns: Non-Engaged audiences (households that have not visited your website after seeing an ad) and Engaged audiences (households that have visited your website). Once a household visits your site, they move into the Engaged segment, where advertisers can choose to increase frequency to reinforce messaging and drive conversion.

Why it matters: Frequency Controls provide additional control over campaign delivery for advertisers who want to manage exposure levels more closely. However, MNTN’s automated optimization is designed to maximize performance, so most advertisers will achieve better results by keeping frequency controls set to Automated. Manual caps are best used in specific scenarios where advertisers need tighter control over impression frequency for prospecting audiences.

Date of Release: 2/17/26

Update: The new Deliverability widget helps advertisers understand how likely their prospecting campaign is to spend its full budget based on current settings. Available in the Audience and Budget & Goal steps of campaign setup, Deliverability analyzes factors like audience targeting, flight length, and frequency caps to generate a real-time confidence signal. If delivery risk is detected, the tool provides recommendations—such as expanding audiences or adjusting constraints—so advertisers can optimize their campaign setup before launch or while editing a live campaign.

Why it matters: Deliverability helps advertisers plan smarter and avoid under-spending surprises. By providing a clear signal during campaign setup, the tool gives marketers greater confidence that their campaigns are built to reach their intended scale. With actionable guidance built directly into the workflow, advertisers can quickly adjust settings to improve delivery and ensure their prospecting campaigns run successfully to budget.

Date of Release: 2/13/26

Update: MNTN’s new HubSpot Integration enables direct customer list imports from HubSpot into MNTN with automatic daily syncing. HubSpot lists can now be used for audience targeting and exclusions within your campaigns, helping keep your CRM data fresh and aligned with your Performance TV strategy. Once connected, your lists update continuously without requiring manual uploads.

Why it matters: This integration simplifies CRM-powered targeting by creating a seamless data connection between HubSpot and MNTN. Advertisers benefit from improved audience freshness, reduced manual work, and more precise targeting powered by up-to-date CRM data. For B2B and CRM-driven marketers, it’s a faster, cleaner way to activate first-party data in Performance TV.

Date of Release: 02/05/26

Update: MNTN Matched audiences now support AND logic, giving advertisers the ability to narrow their Matched audiences using Interest and Geographic segments. Previously limited to OR logic, Matched attributes can now be refined with additional constraints to better align targeting with specific buyer intent. Your selected MNTN Matched attributes continue to form the base audience, while interests and geos can be applied using AND logic to narrow reach with greater precision.

Why it matters: This update gives advertisers greater control and flexibility when building audiences. Whether running performance-sensitive campaigns, targeting specific demographics, or advertising in high-consideration verticals like finance or travel, narrowing allows you to balance scale with precision. The result is smarter targeting that better reflects real-world buying behavior — without sacrificing ease of use in the audience builder.
