As a business owner that is interested in building strong and long-lasting relationships with people, buying an email list is an absolute no for you. This is because their email ids are not verified and they are definitely not interested in your brand. Your email campaigning efforts become a waste of time if your subscribers don’t open your emails or help you increase sales over time. It is also very expected that your mails will be found in the spam folder as the readers have no idea how you got their address or why they are even receiving such emails. Growing your email list might be a slow process at the beginning, but trust that it is an exponential process and will skyrocket once you get to a certain threshold. So have at it, be patient and see the reward at the end.
