More than 4,000 employees have urged their company to stop using the National Rifle Association as a customer.

According to a copy of the letter it viewed, the employees made their request in an open letter addressed to company leaders. On May 24, a teenager went on a shooting rampage in Uvalde, Texas, killing at least 19 students and two adults.

It's not in our power to get background checks or other gun control measures passed by Congress, but we can effect change by ending our commercial relationship with our customer.

According to a copy of the letter published by Protocol, the letter's signatories expressed concern that the NRA would use Marketing Cloud more after the Uvalde massacre. Users can use Marketing Cloud to plan and analyze digital marketing campaigns.

The letter said that the NRA would ramp up its marketing efforts not to prevent future tragedies from happening, but to sow fear, sell guns and abet future atrocities.

It is unconscionable to consider their use of Marketing Cloud to exploit mass shootings.

In the aftermath of the shooting, the NRA continued its advertising activity. After the Uvalde shooting, it started running Facebook ads that urged gun owners to not let Congress limit gun ownership. The weekend after the massacre, the annual convention of the National Rifle Association was held in Houston. Fourteen acres of guns and gear were displayed by the group.

SFGate reported that some employees of the company were cautious about asking the company to end its relationship with the NRA if it was not illegal.

The company has taken action against gun owners before. Customers were banned from using its software to sell certain types of firearms. He supported gun control after the Uvalde massacre. He said in a May 25 CNBC interview that we need to take direct action against gun violence.

An employee told Protocol that the open letter had not been responded to. Employees are expected to attend an all-hands meeting next week.

The company did not respond to the request for comment.
