8 Reasons Why You Should Never Buy an Email List

Thinking about buying an email list? Buying an email list sounds like a quick way to get some business, but it is actually a huge waste of money. In this guide, we’ll share 8 reasons why you should never buy an email list (and what to do instead).

Whether you’ve just launched a new business, or you’re gradually growing an existing one, finding a shortcut to success sounds attractive. And one shortcut that tempts many business owners is the idea of buying an email list.

An email list typically includes a list of names, email addresses, and perhaps other data (like company name or income level), and you can find these lists for sale.

Since you know that email marketing is the #1 way to sell anything online, buying an email list is a great way to launch an email marketing campaign from day one, right?


The truth is, buying an email list is a really bad idea, and a huge waste of money. It’s one of those shortcuts that simply doesn’t work, and will likely cause your business far more harm than good.

Let’s take a look at 8 reasons why you should not buy an email list. Then, we’ll tell you exactly what you can do instead to quickly grow your business with email marketing.

1. You Can’t Trust the Quality of the List

Unfortunately, the people who sell email lists aren’t necessarily very honest. They may make all sorts of claims about the list, but there’s a high chance you’ll find that it has lots of problems, such as:

  • Missing or incomplete data (e.g. having the wrong names for individuals on the list)
  • Out-of-date information (loads of the email addresses that no longer exist, or are abandoned).
  • Email addresses illegally harvested from the web (people who haven’t chosen to be on any list, which is against the CAN-SPAM Act)

While it might sound great to get an email address of 5,000 or 10,000 names overnight, it’s going to be pretty worthless if it’s an out-of-date list full of junk data made up of people who never wanted to be on the list in the first place.

Not only that, but if the email list was harvested through any number of illegal means, you could be subject to penalties of up to $16,000 for each separate email you send. Yikes!


2. You’ll Come Across as a Spammer

Let me ask you a question. Do you enjoy receiving unsolicited emails?

I’m guessing you probably don’t. Especially when the content of those emails contains a marketing message.

Chances are, you probably delete those emails. And, if you get a lot of them from the same company, you will probably unsubscribe, or even mark them as spam.

Now, you might believe that your marketing emails are really well written and packed with high-quality information, but from the recipient’s perspective, you’re just another unknown company barging into their inbox.

When people join an email list that ends up being sold to another company, they typically have checked a box or glanced at some terms and conditions about receiving offers from “related companies”. Chances are, they’ve forgotten that they ever did this, and they’ll simply see your messages as unwelcome spam.


3. You’ll Run Into Trouble with Your Email Service Provider

If too many of your messages get marked as spam, you’ll quickly get on the wrong side of your email service provider. (That’s the company that sends out your emails, such as AWeber, Mailchimp, or Constant Contact.)

That means your account may well be closed, you could be fined, and your email service provider may even take legal action against you.

But that’s not all. The simple act of buying an email list may be strictly forbidden by your email service providers. For example, Aweber considers buying email lists spamming, and it is a serious violation of their service agreement:

“[You may not] use email lists that you purchased, rented, leased, or in any way bought from a third party. This includes email addresses that you purchased via co-registration.”


4. Other People Are Using the Exact Same List

Here’s something you may not have considered: when you buy an email list, other people are using the exact same list as you. They bought the list, just like you, and they might be sending out email after email to the same recipients.

What are the chances that the people on your newly bought list are already annoyed by the number of marketing emails they’re receiving? These people are unlikely to be receptive to your offers. They may have even put filters in place (or abandoned the email address altogether) so that they never see your emails.

5. You’ll Get a Poor Response Rate

Let’s say you buy an email list of 10,000 names. You figure that on a 5% conversion rate, you’ll sell 500 units of your new product, which costs $99 – netting you $49,500. Not bad, right?

Well, your response rate could be far, far lower than 5%. In fact, you might find that the vast majority of people on the list never even open your email, let alone click through to your sales page.

If only 500 people even take a look at your email, and they’re not at all engaged with the offer, then you might not sell a single item.

Average open rates are around 20 – 25% for healthy, targeted lists. Lists that you purchase are likely to have far lower open rates.

6. Your Reputation Will Take a Serious Knock

As well as your email service provider cutting you off (and potentially taking action against you), buying an email list opens you up to broader problems with your reputation.

Imagine, for instance, Googling your company name only to find that three of the results on the first page are angry rants from people who’ve received multiple unsolicited emails from you.

Sound a bit alarmist? Even a few negative tweets can cause significant PR problems.

Reputation is crucial online, and you definitely don’t want to be spending huge amounts of time and money on reputation management, trying to get search results buried.

7. You Might End up Facing a Big Fine or Legal Bills

Most countries have laws against sending out unsolicited bulk email, such as the CAN-SPAM Act in the United States.

While you may still be on the right side of the law–even using a bought email list–you aren’t out of the woods yet. If lots of subscribers complain (and they probably will), you may face a costly battle to simply prove that you didn’t do anything technically wrong.

Also, keep in mind that different countries (such as Canada) have different laws. If the email list you bought includes people from another country, you will have to abide by those laws.

8. No Reputable Expert Recommends It

Read any major blog on email marketing and you’ll hear the same thing over and over again: don’t buy email lists.

On many marketing topics, there are differences of opinion about which strategies work and which don’t – but this is definitely one key area where everyone agrees.

Buying email lists is a waste of money and time, and may seriously harm your company.

So if you can’t buy an email list, what can you do instead?

There’s a pretty obvious solution to this problem… build an email list from scratch!

But if you’re just starting out, you might not be sure where to begin.

So, here’s a “nutshell” guide to getting started with building your email list (the right way).

Step 1. Attract an audience with useful, engaging content

If you’re going to get people to sign up for an email list, you need a site that will draw them in. That way, you’re giving them something of value (great content) before asking them for something in return (their email address).

This builds trust, and you can sell something later on with much greater ease.

Step 2. Create a lead magnet

A lead magnet is an incentive that you offer to potential subscribers in exchange for their email address.

Depending on your niche and what your audience is most likely to want, this could be a list of great resources, a short getting started guide, or even a video tutorial.

Here’s an example of a lead magnet on our blog:


Step 3. Get a reputable email service provider

Scrap any list(s) that you’ve bought in the past, and don’t try to cut corners by sending out mass emails through your email client (e.g. Outlook or Gmail). Your ISP will almost certainly stop or penalize you for this, and you’ll miss out on many crucial features that email service providers offer.

Then, set up an account with a reputable email service provider (here’s a list of our favorites).

Step 4. Add highly visible optin forms to your website

Simply tucking a bland form away in your sidebar isn’t enough to build an email list quickly. You’ll ideally want to use multiple types of optin forms, which may include…

To easily integrate any of these with your website and your email service provider, check out OptinMonster.

The bottom line? Never buy an email list. It’s simply not worth the cost, in terms of money, time, or hassle.

Instead, grow your own targeted, responsive list of potential customers who are eager to hear from you, and you’ll see far greater success!

    a well balanced and supported coverage of the risks of buying email addesses. I was at the point of taking that very step.
    I am now utterly persuaded to avoid at all costs.
    many thanks.

  5. Hello,
    Thank you for such a informative article. I wanted to ask one thing. We have had a lot of clients from the time when we were not doing Email Marketing. We have their data in a list on our local system. Can we send emails to that list through Mailchimp? What effect can this email campaign have on our company reputation?

      Good question! My answer is that it depends on how they ended up on your list. If they signed up to receive emails from you, then go ahead and email them. But, if it’s been a while you’d probably be best served by sending a “do you want to hear from us?” email.

      First, add a tag in Mailchimp to keep your opt-ins together (we use a “newsletter” tag to track the people who want to receive emails from us).

      Next, send an email to your entire list asking them to opt-in (set up Mailchimp to automatically apply your “newsletter” tag to the people who click the opt-in link).

      From there, you’d use the opt-in list (everyone tagged “newsletter”) for your email marketing and don’t email anyone who didn’t opt-in.

      It’s helpful to create a lead magnet to entice people to opt-in.

      I hope that helps!
