About Ongage

Ongage is an email marketing platform, enhanced by its AI Content Studio, and built to help performance marketers drive results across email and SMS. At the heart of its offering is advanced email campaign management, where list quality directly impacts reach, engagement, and ROI.

To help users maintain cleaner lists and improve deliverability, Ongage integrated Bouncer’s real-time email validation directly into the platform. The result: fewer bounces, higher inbox placement, and a more seamless workflow for busy marketers.

The Challenge

Manual list validation

Without validation, Woodpecker users face two major challenges:

Slow operations

Ongage users had to export their contact lists, validate them using an external tool, and then re-import the cleaned data, every time. The process was repetitive and time-consuming.

No list cleaning in the workflow

Since validation happened outside the platform, it created friction in the UX. Ongage wanted to eliminate that gap with a built-in, automatic solution within their existing interface.

The Result

Ongage embedded Bouncer to improve customer experience:

Real-time email validation

Users validate emails without leaving Ongage.

  • Results feed directly into customer data
  • No external tools or manual import steps

Optimized for volume

Bouncer’s API handles high volumes with speed and reliability.

  • Fast response times
  • Stable performance during large sends

Credit fallback mechanism

A built-in safeguard ensures validation keeps running without interruption.

  • Prevents campaign disruptions
  • Keeps workflows smooth

Conclusion

Email validation is no longer a separate task. With Bouncer fully embedded, Ongage users keep their contact lists clean from inside the platform — saving time and simplifying segmentation.
