If you’re a marketer, you’re likely juggling several tasks at once such as feeding the sales funnel, increasing brand awareness, driving engagement, and creating valuable content pieces. And if you use email as part of your marketing program (and I seriously hope you do), you have likely been solicited by companies that want you to buy an email list. In this post, you’ll learn why buying or renting email lists: Won’t help you achieve your marketing goals Could get your email account shut down Damages your sender reputation, decreases recipient engagement, and negatively impacts your sender score Sounds scary, right? Don’t worry; there are plenty of alternative email marketing list building strategies you can use to grow your email lists that are covered in this post too! Purchased vs. rented email lists A purchased email list comes with email addresses, names, and potentially additional data about people who have opted in to receive affiliate emails at some point in time. A rented email list is one that the owner has complete control over. The renter never actually sees or enters into his or her email list but rents for a predetermined amount of time. Both purchased and rented emails lists are offered by companies that claim to have thousands of “legitimate” emails that can help you create more leads and make more money. And it’s as easy as entering in your credit card. But like most things in life, taking the easy way out rarely benefits you in the long run. 1. You won’t achieve your email marketing goals Ask yourself what you hope to achieve with a purchased email list. Are you trying to increase engagement and drive more leads? If so, purchasing an email list often has the opposite effect. Purchased or rented email lists almost always consist of low-quality emails (often including incorrect or out of date contact information). These contacts may have, somewhere along the line, checked a box that they were OK with receiving emails from affiliate businesses. But, these people have not specifically verified that they want to receive emails from your business or organization. This is a problem for a couple of reasons: 1) If somebody receives an email that they’re not expecting, they’ll likely ignore it or worse–complain. Now you’re annoying recipients and damaging your sending reputation. 2) A poor reputation will lead to decreased inboxing and can even get you blacklisted which means your emails will not be delivered. It’s tough to meet your marketing goals if no one sees your content. And it’s not always the inbox providers (Gmail, Yahoo!) that stops you. 2. Reputable ESPs will shut down your account Email Service Providers (ESPs) can’t follow through on business promises like having the highest possible delivery rates if some of their senders are sending email to a purchased email list. If you’re not sending email through a dedicated IP and sending high volumes of email, you’re likely sharing your IP with several other email senders. So, if one email sender gets blacklisted or has a low sender score, this affects all other senders on shared IPs. And so ESPs, including SendGrid, don’t allow email campaigns to be sent to purchased email lists. There are a lot more details that explain why this is the case that is covered extensively in SendGrid’s 2018 Email Deliverability Guide. 3. You damage your sender reputation, engagement, and online presence Every email domain has a reputation that can be scored and here’s how you can find out how your email program fares. Even if you can still send email after you’ve sent emails to a purchased list, many times purchased email lists also include emails that have long been shut down or are just plain fake. Email addresses known to be old and unused (i.e., have not given permission to receive email) are known as a spam trap. When email is sent to them, it’s a clear indicator that the sender is spamming and almost always results in the sender landing on a blacklist. Make sure you’re not sending email to spam traps by educating yourself about how to avoid them. Even if you avoid falling into a spam trap, your engagement rates will likely plummet after you send an email campaign to a list that includes purchased emails. This is a compounding problem for your email program because decreased engagement rates will negatively impact your sender score and make it even harder for even engaged recipients to receive your emails. What are some alternatives to purchasing an email list? Don’t cave to the temptation to purchase an email list! Not only is the practice dangerous, but there are better alternatives out there that improve your sender reputation, help you reach the right people, and convert more leads. Consider providing value in the form of content (guides, blog posts, or case studies) instead of just asking somebody to hand over their email address. Those who do sign up afterward are more likely to be high-quality, engaged, and ultimately higher converting leads. Provide multiple places for people to sign up for your email list. You could have a banner on your blog or resources page, or a well-timed pop up that appears if a reader scrolls long enough down your page. No matter where you ask people to sign up for your email, remember to focus on the value you’re providing to your recipient before focusing on your ask of your recipient. Use a reliable Email Service Provider (ESP). If you don’t have the resources for a dedicated IP, it’s important to use an ESP that holds high standards and kicks out bad actors who send spam email. That way, you won’t be putting trust in strangers’ email programs and tactics.
