Your customers expect personalized messages, and your peak seasons don't wait for anyone, but scaling both at the same time has always created more coordination than it should. The June release of Acoustic is a direct response to feedback from customers who needed fewer handoffs when it matters most, whether that's controlling the pace of a large send or trusting that a behavioral signal is working before it reaches live data. This release puts more of that in your team's hands, so you can scale with confidence when the stakes are highest.

Pace your largest campaigns without waiting on IT

 

 

Picture this: a big promotional send goes out, and thirty minutes later your site is crawling. Customers are abandoning carts, your support inbox is filling up, and the revenue you were trying to drive is evaporating while your team scrambles. A spike in send volume hitting your ecommerce platform or loyalty API all at once can do exactly that, and until now, preventing it has meant coordinating with IT every time you need to control the pace of a high-volume campaign.

Send rate throttling puts that control back where it belongs. From within your campaign workflow, you can set how many contacts receive your message per hour, see a projected send duration before you hit launch, and let the system distribute volume at a steady pace rather than in one overwhelming spike — no ticket required. For marketers running peak-season promotions or time-sensitive loyalty campaigns, the ability to protect delivery and site performance without waiting on anyone else is a welcome change.

Display dates and numbers the way your customers expect to read them

 

 

Personalization is supposed to make messages feel more relevant, but a raw data value pulled directly from your database can do the opposite. When a customer opens your email and sees "2026-06-04T00:00:00Z" where you meant "June 4, 2026," or "1299.99" where you meant "$1,299.99," the message loses credibility before they've even read it. Fixing those display issues has typically meant looping in a data team or applying a workaround that belongs in a developer's toolkit.

Acoustic's enhanced personalization formatting for dates and numbers gives you direct control over how those attributes appear in your messages across email, SMS, WhatsApp, and mobile push. Choose from seven date format options and configure number separators to match your audience's regional expectations, all from within the message composer. The underlying data never changes; only the way it appears to your customer does.

Know your signal is working before it goes live

 

Behavioral signals — the actions customers take on your site — are some of the most valuable inputs your marketing has, and signal composer is built so your team can capture them without needing a developer to set it up. Configuration is self-serve, and with the June release, so is validation.

With signal composer preview, you can test before anything reaches production. Run your signal against the live page, see exactly what it will capture, and surface any errors or warnings while you still have room to fix them. The result is a faster, more confident path from setup to publish, with less risk of data quality issues making their way into your audiences and automations down the line.

More ownership and momentum

 

The common thread across this release is simple: the less your team has to rely on others for execution, the more confidently you can scale when it counts. Pacing a send, formatting a personalization attribute, and validating a signal — these are things your team can now handle independently, without leaving your campaign workflow to do it.
