Company Background and Challenge

ArcaMax (founded in 1999) is a leading provider and publisher of news and syndicated features. ArcaMax distributes hundreds of features to millions of subscribers via email daily. Their main source of revenue is from advertising, which means that content is free for subscribers/readers.

Like most online publishers, ArcaMax relies on its subscriber strength and its constant growth to drive revenue. They have a list of over 3.5 Mn people and more email opens and engagement with these subscribers is always needed to grow the business.

They faced a few challenges with their existing system:

  • ArcaMax used in-house systems to send emails to their regular list of subscribers.
  • They needed an ESP who would ensure that their initial confirmation emails were successfully delivered to a new subscriber’s inbox and not their spam folder.
  • With these emails landing in spam, it created an obstacle to steady growth in subscribers.

How Pepipost’s Email Delivery Service Helped

As the number of subscribers for a publishing house like ArcaMax is always crucial to the business, the instances of first confirmation emails going to spam had to be reduced on a priority basis so as not to be an obstacle to the growing user base/ subscriber statistics.

The primary source of revenue for the business is advertising. Any obstacle like problems with inboxing confirmation emails for double opt-ins could largely impact the core business.

Our object was to reduce the number of first emails that ended up in spam and provide a better way to increase and engage with a growing email subscriber base.

While some companies reject double opt-ins, ArcaMax, as well as the Pepipost Email Delivery Team, embraces it.

As an industry practice, double opt-ins are always considered the preferred option because:

  • Double opt-in ensures that a company’s list is filled with subscribers who willingly engage with the content
  • Minimizes the chances of bots from signing up
  • Double opt-in makes it easier to comply with dynamic changes to privacy regulations in this space
  • ArcaMax respects both their readers and their advertisers equally and to balance their core company objectives effectively, maintaining credibility is always important.

Our email delivery experts first worked on the entire flow and process of the existing system to give it more controlled settings. After these changes, Arcamax was able to:

  • Prevent toxic email ids from being sent the confirmation email right away
  • Improve their domain reputation

Pepipost’s AI-based email delivery features helped in better configuration and connection management, which in turn resulted in better email inboxing. By focusing on:

  • Identifying what to inject into the system,
  • Closely tracking the progress and making real-time adjustments, they witnessed a 20% improvement in first email delivery rates for new subscribers.

Arcamax was able to improve deliverability and ensure new subscriber numbers were consistent. The overall strategy also helped them get more confirmed subscribers.


After the successful execution of the strategy, the below were the results:

  • Improved email deliverability rates within the first week
  • 20% increase in first email inboxing rates
  • Double-opt in implementation allowed more spam-free and confirmed subscribers to be on the email list
  • Confirmed subscribers in turn meant a significant reduction in emails that ended in spam

ArcaMax now considers us to be a partner who helps them achieve their objectives. From being one of our first clients, we’ve come a long way in improving their inboxing and customer outreach.
