Product release: 500k audiences + faster, clearer segmentation

How the Grinch tried to steal your segments (…but failed) because Vector shipped too many good updates this week.

Marketers fight familiar battles:
Segments that appear “stuck,” filters that feel unwieldy, audiences that max out too quickly, and hours lost manually typing values that should really just paste in cleanly.

This week’s release knocks out several of those frustrations in one shot.

Below is what’s new and more importantly, what it unlocks for Vector users.

1. No more phantom “Processing”

Just clean, accurate segment evaluation.

‍

Segments now track real evaluation state, which means you always know:

• When the segment last successfully ran
• Whether it’s actually ready to run again
• Its last known audience size (not a guess or placeholder)

UI enhancements:

• Misleading “Processing” labels are gone unless a segment is actively running
• “Estimated Audience Size” → “Audience Size,” with a clear badge if the segment hasn’t run yet

What this means for Vector users

This update resolves one of the most common questions: Is my segment actually running?
‍
Now Vector SHOWS you exactly:

• What’s happening
• What’s not
• What to expect next

This leads to cleaner planning, smoother troubleshooting, and far more reliable alignment across Marketing, Sales, and CS. You spend less time double-checking work and more time activating audiences that behave exactly as expected.

Que the universal reaction when you realize you can finally see what’s running, what’s not, and what’s next:

2. A cleaner, stronger segment builder UI

For better handling of complex logic.

The segment builder got a significant visual and functional refresh:

• Large filter groups and long-value lists render more efficiently
• The layout is cleaner and easier to scan
• New Vector-custom badges ensure consistency across the app

This isn’t just cosmetic: it makes the builder more resilient for customers with complex ICP definitions, multi-attribute targeting, and deeply nested conditions.

What this means for Vector users

Your segmentation work becomes dramatically more readable and maintainable:

• It’s easier to review what you built
• It’s easier for teammates to understand and reuse your logic
• It reduces the chance of errors hiding inside long logic chains

Power users get a smoother workflow. New users get clearer guidance. Everyone gets a faster experience.

3. NEW: Copy/paste selects: bulk values in seconds, not hours

You can now paste:

• Comma-separated values
• Newline-separated values
• Whole spreadsheet columns

…directly into select fields like job titles, industries, domains, and more.

The platform automatically:

• Adds custom values where allowed
• Matches against existing values
• Prevents security risks through baked-in input protection

What this means for Vector users

This is a major quality-of-life upgrade for anyone building larger audiences or importing CRM targeting lists.

Benefits include:

• Far faster audience creation
• Less repetitive typing
• No more reformatting spreadsheets to match UI fields
• Reduced error rates when handling large data sets

ABM teams, agencies, and growth marketers will feel this improvement immediately.

4. Audience size limits increased 5×: from 100k → 500k

Broad audiences can now support up to 500,000 contacts.

What this means for Vector users

This removes one of the biggest constraints marketers hit when activating large ICP pools or “always-on” paid programs.

You can now:

• Reach larger in-market audiences
• Improve match rates
• Feed more real behavioral signals into your GTM engine
• Build broader plays without worrying about cap limits

This opens the door for richer, multi-channel activation and better top-of-funnel coverage leading to a moment like this:

5. Bid Agent: your safeguard against holiday auction volatility

As buyers go offline for PTO and auctions swing wildly, Bid Agent automatically adapts your bids — minute by minute.

It helps by:

• Lowering bids when activity drops
• Escalating bids when high-intent buyers return
• Reducing wasted spend during off-hours
• Smoothing out cost spikes from seasonal fluctuations

What this means for Vector users

Your campaigns stay efficient even when markets get unpredictable.
This is especially powerful when paired with newly expanded segments:

• Broader reach
• Smarter pacing
• Better efficiency

While the Whos are busy singing around the tree, Bid Agent is quietly keeping your CPCs from turning into holiday chaos.

This week’s recommended play:

The Copy-Paste Broad Audience Activation

With 500k audience limits and bulk-import selects now live, you can build powerful broad audiences faster than ever.

Try this workflow:

1. Build a broad “ICP + in-market + recent traffic” audience
2. Paste job titles, domains, or company lists directly into the builder
3. Push the segment to LinkedIn + Meta
4. Turn on Bid Agent to manage auction volatility
5. Monitor stable performance as the season shifts

This is a scalable segment you can run all year not just during holidays.

Final thoughts

In the original story, the Grinch thought he could stop Christmas by taking all the pieces the Whos relied on.

‍
He learned, of course, that the real power was in what they built together.

These updates do the same for your GTM:

• More transparency in your segments
• More power in your audience building
• More stability in your ad performance
• More room to grow

The system holds. The work continues.

And your GTM motion grows three sizes today.
