Expensify CEO David Barrett emailed the company’s 10 million customers on Thursday with an unusual pitch: Vote for Biden, he urged them, or risk damaging the nation’s democracy. The email has been met with both support and condemnation, with critics calling it “political propaganda” and a misuse of customer emails.

Barrett told CBS MoneyWatch that his company sent the email to its 10 million customers on Thursday because it’s “trying to do what we can to support and defend democracy against voter suppression.” Barrett founded Expensify in 2008 to make it easier to file expenses…

Expensify’s email was an extension of the company’s work on social issues such as Black Lives Matter and anti-hunger initiatives, Barrett told CBS. He added that he and his staff had discussed how to get involved in the November 3 election, and a majority of staff voted in favor of sending the email to their customers.
