Mailing lists are lists of either postal or email addresses that can be used by a marketer to send promotional mails. You can build a mailing list yourself through your website, or you can buy or rent it for specific mail blasts.
How to get a marketing list?
Building a mailing list yourself
Using your website or an existing newsletter to gather the contact data for your prospects list is probably the best way of generating a marketing list. You can even ask your customers for their email address at your shop, or use a promotion to get them. Advantage
By building a marketing list yourself, you can be 100% sure that the people on it are interested in your services and will not consider you a spammer. Buy from mailing list brokers
Some companies specialise in gathering and then selling mailing lists, segmented by demographics, job titles or geographical location. Some can even be commissioned to build a marketing list on your behalf to your exact specifications.
While using a reputable broker to buy mailing lists is generally not a big risk, the results you will get will be worse than if you had built the list yourself. Spamming
If you buy from somebody who is not a legal mailing list broker, you risk all your emails being classified as spam, and people making formal complaints about your company. Buy only options in mailing lists refer to an situation where people have confirmed that they are agreeable with their data being shared with third parties. Rent a mailing list
Some companies offer the possibility of renting their mailing list for a single mailing, for example to offer a related product to their audience. In most cases, they will not allow you to use your existing email solution and will require you to provide them the creatives and mail them to their users.
