Under the Can-Spam Act, what must a real estate company do when sending out email messages?

The Can-Spam Act establishes regulations for commercial email messages to protect consumers from unsolicited emails. One of the primary requirements under this act is that a real estate company must obtain consent before sending unsolicited emails. This means a recipient must have opted in to receive communications from that company, making option B the accurate choice.

In terms of the other options, while signing emails personally may add a touch of personalization, it is not a requirement of the Can-Spam Act. Advertising the brokerage firm's benefits is a marketing strategy but does not fulfill the legal obligation of obtaining consent for unsolicited emails. Additionally, the format in which emails are sent, whether HTML or plain text, is not stipulated by the act, making the emphasis on HTML format irrelevant to compliance. Understanding these requirements helps ensure that real estate companies operate within the legal parameters while effectively reaching their audience.
