Cvent Holding (CVT) 8-K Entry into a Material Definitive Agreement

Exhibit 99.6

EMAIL SUBJECT: Cvent Plans to Go Public!

FROM: Reggie’s Alias

Dear XYZ,

As a valued Cvent partner, I wanted to take a moment to personally share some exciting news with you. Today, we are proud to announce a momentous milestone for Cvent as we plan to go public by merging with Dragoneer Growth Opportunities Corp. II (Nasdaq: DGNS). When we complete this transaction, Cvent plans to again become a public company, ultimately trading under the ticker symbol “CVT.”

We could not have done this without the trust that you have placed in us for the past couple decades. This opportunity helps us further invest in and reinforce our commitment to delivering the exceptional products, service, and support that you’ve come to expect. In fact, we selected Dragoneer because they share our long-term view and have a proven track record investing in and supporting globally recognized technology brands such as Uber, Airbnb, and Slack, to name a few.

We are thrilled to go public again because it provides significant financial resources to further strengthen our business and accelerate investments across our platform and related services – for virtual, in-person events, and hybrid events. With anticipated proceeds of this event at $801 million, we can accelerate our innovation, deepen our functionality, reduce debt, and expand our customer-facing teams – all to provide you with better solutions and service than ever before. We’re all excited to kick off the next chapter in Cvent’s journey. For more information on this transaction, you can view our press release here.

We’re witnessing the digital transformation of our industry, which has been accelerated by the global pandemic. Over the last year, events moved to virtual and online experiences, and we invested heavily in expanding our virtual event capabilities. Now thousands of organizations trust Cvent for their virtual events.

I want to personally thank you for playing an important role in getting us to this point. The last 18 months have been tough on all of us in so many ways. We are extremely grateful that you continue to partner with Cvent to get the most out of your meetings and events.

Finally, if you haven’t already registered, I’d like to personally invite you to attend our customer conference, Cvent CONNECT on August 1-4. We have a free virtual option that is open to everyone. The event offers the perfect opportunity to see a hybrid event on the Cvent platform in action, to learn about the latest industry trends and insights, to network with your peers, and to interact with our technology. Please register here.

Warm Regards,

Reggie Aggarwal

Cvent CEO & Founder
