Exhibit (a)(5)(I)

September 25, 2018

Dear Valued Customer,

As you may have already seen, Staples launched their tender offer yesterday morning, allowing Essendant shareholders to begin tendering their shares to Staples and marking an important milestone toward completing our transaction.

We know many of our independent office products resellers have voiced questions about Staples’ plans for Essendant following the completion of the transaction. To that end, we want to share the attached letter we recently received from Staples’ Chief Executive Officer, Sandy Douglas, confirming our discussions with him and others at Staples and outlining the ways this transaction will enhance Essendant’s ability to efficiently deliver a strong product and solution offering at more competitive prices, which will clearly benefit independent resellers.

As you’ll read in Sandy’s letter, this transaction will allow us to benefit from Staples’ lower costs, which will be shared with our customers, and will allow us to leverage Staples’ vast product assortment to provide customers with additional product solutions. In addition, Staples has heard the concerns voiced by some of our customers about how Essendant customer data will be used after the transaction closes. Staples has committed to ensuring that the commercial operations of Essendant and Staples will remain completely separate, as they are today. Staples plans to put in place a strong, externally monitored firewall to ensure that Essendant customer data is entirely insulated from Staples’ sales team.

It is clear from Sandy’s letter that Staples appreciates the unique value proposition of Essendant’s customers and will continue to support their success in the market. We are confident that, upon closing, Essendant customers will quickly see benefits from this arrangement.

Over the coming weeks, Essendant will continue to work toward meeting the regulatory, shareholder and other conditions necessary for completion of the transaction, which we expect to close in the fourth quarter of 2018. As we’ve previously shared, your Essendant point of contact remains the same, and you can be sure that our relationship with you remains our top priority.

Thank you for your continued partnership. We look forward to sharing the benefits of this transaction, continuing to invest in the independent dealer channel, and providing your business with the products and solutions it needs to grow. We will keep you informed of further developments as appropriate, but in the meantime, please feel free to reach out with any additional questions.

Sincerely,

Dear Ric:

I wanted to take a moment to summarize the benefits we see from our potential transaction for Staples, Essendant and, most importantly, Essendant’s independent dealer customers.

While we understand that Essendant dealers may be uncertain about working with Staples going forward, we are hopeful they will give Essendant (powered by Staples) a chance to show them what we can do together. I am confident they will see immediate benefits and, over time, even more reasons to maintain and grow their business with us.

I recognize it may be tough for dealers to see themselves working with a company owned by Staples, who they have long viewed as a big, arrogant competitor. For example, some may be worried about Staples leveraging their customer data in competition with them. We can say unequivocally that we will put in place a strong, externally monitored firewall to preserve the integrity of Essendant dealer’s data, keeping it 100% insulated from Staples’s sales teams. Staples’ commercial operations will remain completely separate: dealers, other than the benefits they will receive from Essendant’s added capabilities, will continue to compete with Staples as they do today.

This transaction will allow Essendant to procure product from manufacturers at Staples’ lower cost and allow the combined company to negotiate even better pricing. Independent dealers have a higher cost of goods, disadvantaging them when competing with larger companies that can use their scale to obtain products at lower costs. Essendant’s lower costs, which can be passed on to dealers, will help them narrow this gap and provide additional value to their customers.

Some dealers might ask: why would Staples do this? Our market analysis and experience tells us that independent dealers win business, for the most part, because of the high touch service they provide and their close local and community relationships, while Staples earns business where price and process are deciding factors. Therefore, helping the dealers flourish will grow Essendant’s wholesale business, and the sales and profits for the combined organization.

As such, our goal in this transaction is certainly not to marginalize the dealer community Essendant serves, as this would be self-defeating. Instead, we want to help dealers grow their business and take them to new levels of sales, profits, and strength! Adding our supply chain capabilities, expanded product assortment, and e-commerce innovation to Essendant’s offering can provide dealers with even more resources to help them succeed—accelerating profitable growth for all of us!

In addition, we are working aggressively to make Staples much better at what it does and are hopeful that, by teaming up with Essendant, we can help independent dealers be more effective at what they do. In short, we believe that 1 + 1 can equal much more than 2!

Please feel free to share the contents of this letter with the dealers as you feel is appropriate. I look forward to continuing to work with you to make this transaction a reality and achieve its full promise for Essendant and your independent dealers.

Ric, on a final personal note, I am excited about the potential of working together to support your dealers. I have a personal history of working with local Coca-Cola Bottlers and have seen over and over again the growth potential of empowered local entrepreneurs and their businesses. In a world of bigger and bigger business, there is a winning place for well-connected local companies that are able to get the benefits of scale in their businesses. This is what we hope to help with for you and your dealers.

Sincerely,

/s/ Sandy Douglas

Chief Executive Officer

P.S. As soon as it’s appropriate, let’s have a meeting with the dealers to hear all of their questions and concerns. I know we can win their trust with our actions, but it starts with listening well.
