There are nearly 4 billion active email users around the world. So it makes sense that email is one of the most popular ways for businesses to reach out to potential customers.
But you cannot simply reach out to anyone and everyone via email whenever you see fit. There are anti-spam laws in place to prevent businesses from abusing this communication method. In the U.S., the CAN-SPAM Act includes a wide array of laws related to commercial emails. The GDPR in the E.U. and Canada’s CASL laws may also apply to businesses in the U.S. if they have any international customers on their email lists.
