Imperia Online Achieves a 99% Inbox Placement Rate and Places 172,000 More Messages in Inboxes with Validity Sender Certification.

The challenge:

Ensuring reliable email deliverability in a competitive industry.

As a leading online game production company, Imperia Online depends on email to connect with their global audience of over 70 million players. Their email marketing program is essential for announcing new features, promoting tournaments, and keeping players engaged. In the fast-paced gaming industry, seamless communication can mean the difference between building a thriving community and losing momentum.

Despite optimizing their email strategy by avoiding hyperlinks, Imperia Online still found their emails landing in spam folders. Another aspect of their deliverability issues included trouble sending to subscribers with Yahoo inboxes.

“Email is essential for keeping our vast player community informed and engaged,” remarked Borislav Mitev, Imperia Online’s Head of IT. “We needed a solution that would ensure our messages arrived intact in players’ inboxes without fail.”

To help close the communication gap and take their email program to the next level, Imperia Online turned to Validity for support.
