Washington (CNN) Starting next month, customers will be able to donate up to $200 to US presidential campaigns through Amazon's Alexa.

Amazon announced the new elections feature Wednesday and said candidates can start signing up on Thursday to receive campaign contributions through the voice-controlled assistant.

"With Alexa Political Contributions you can donate to participating 2020 U.S. presidential campaigns by simply saying 'Alexa, I want to make a political contribution' or "Alexa, donate [amount] to [candidate name]," Amazon said in an announcement.

The minimum donation using Alexa is $5, while the maximum is $200 per campaign. Alexa can only donate to presidential campaigns that have signed up to accept donations from Alexa.

Alexa Political Contributions is powered by Amazon Pay, according to the company, and will use the default payment information associated with accounts to complete the campaign donations.
