Why Buying Mailing Lists is a good idea, rather than building them up yourself.

The hardest part of email marketing is building up a good quality mailing list … or knowing where to start when buying mailing lists. Your mailing list needs to be filled with up-to-date contacts from your target audience. Doing this from scratch is very time-consuming, and PPC can quickly become expensive. If you’re struggling, you might want to consider simply buying a mailing list instead.

When buying mailing lists, make sure they are GDPR compliant

If you work with a reputable business that can provide GDPR-compliant data, then buying mailing lists can work well for your business. 

Sadly, there are a number of businesses selling mailing lists that you really cannot rely on. Out-of-date and non-compliant data is rife amongst the less scrupulous providers, so be sure to do your research before buying. Remember, if it sounds too good to be true, it probably is too good to be true!

So what makes us different? At Data Bubble, we ONLY supply mailing lists that are GDPR-compliant. We’ve been in business since 2009, have come through Brexit, GDPR and COVID, and are STILL growing year after year where others have fallen by the wayside.

Only buy trusted mailing lists of high-quality B2B data so that you can increase your lead generation.

How can buying mailing lists increase your customer base?

There are still some who think that GDPR rendered the purchase of mailing lists defunct. But don’t worry, that’s a total myth – buying mailing lists is perfectly legal.

Not only is it legal, but it has the potential of growing your business quickly. And if you’re buying your mailing lists from a reputable, CIM accredited organisation such as Data Bubble, your business is much more likely to get a great return on the investment you put into marketing.

According to OptinMonster, email marketing can have a 4400% ROI. That’s absolutely massive! If you aren’t using email marketing at the moment, that means you’re missing out on a lot of potential leads and conversions.

10 reasons why buying mailing lists is the cost-effective​ choice

Here’s the thing … you need to be compliant and maximise your return on investment. Mistakes can be costly both financially and reputationally, so good quality, accurate data is essential. Here’s why you need to buy a mailing list:

1. Saves Time – It’s quick, and you could have a mailing list of 5,000+ contacts within an hour or two, freeing up valuable selling time for your team

2. Good Mailing Lists are More Efficient – Your sales team need to use their time efficiently by building relationships, making sales calls and sending emails, rather than doing desktop research

3. Good Email Lists Increase Sales – Getting a mailing list that contains only your buyer persona ensures your team are concentrating on your ideal target market. According to research, 24% of companies gain more leads when they use a buyer persona

4. You Have Accurate Information – B2B data is kept up to date through various processes, including screening against certain industry files and conducting regular verification exercises. This means it’s more accurate than often out-of-date websites and directories, and often companies’ own databases!

5. You Can Target The Right Person – An email list contains the contact details for the person you’re targeting, so no more being passed around the company trying to find the right person


6. Reduce Waste – A mailing list eliminates irrelevant information such as holding companies, regional offices and branches. This allows your salespeople to get straight to the decision maker

7. Very Targeted Mailing Lists – List owners will collect additional information when conducting telephone verification calls, such as number of employees, import / export info, type of fleet vehicles or star rating of hotels. This means buying data allows you to really target your ideal audience

8. Mailing List Compliance – Various regulations need to be adhered to when conducting marketing campaigns, such as GDPR, the Privacy and Electronic Communications Regulations (“PECR”) and the Corporate Telephone Preference Service (“CTPS”). A good data broker such as Data Bubble will eliminate non-contactable, non-compliant B2B data records and only supply compliant lists, thus keeping your company’s reputation intact and your bank balance safe from potential fines

9. Protect your Team’s LinkedIn Profiles – LinkedIn is working hard to eliminate spammers from its site and will block profiles that are classed as spam. Using a mailing list will protect your team’s LI profile, allowing them to continue connecting with people they know

10. Protect your Company – Many directories include a clause in their Terms and Conditions that prohibits the use of their information for marketing purposes. As such, using directory information may be breaking the law, which could cost the company both financially and reputationally. Mailing lists exist specifically for marketing purposes, so give you peace of mind when marketing

Q – At What Point does a Contact on the Mailing List become Mine?
A – As soon as someone on the list gives you their permission (“opts in”) to continue with marketing calls / emails, or they become a customer by making a purchase from you, then they are deemed as being yours from the point they gave consent / made their purchase. If you have not gained your own consent, the data is not yours.

Q – What are the Rules regarding the Use of Email Addresses?
A –
In order to conduct marketing to consumer email addresses, you must have the person’s specific consent. However, business email addresses (e.g. [email protected]) can often be marketed to under the legal basis of Legitimate Interest, though for some, consent is still needed.

Legitimate Interest can usually be relied upon if emailing a Limited Company, PLC, LLP, Government Organisation or Scottish Partnership. However sole traders and certain other types of partnership still require consent.

We would only ever release email addresses to you that you are able to use for direct marketing. Sometimes, for consumer email campaigns, we may carry out the email broadcast on your behalf rather than releasing the data to you. This is to ensure compliance and to enable the appropriate monitoring of individuals’ opt-out requests.

Remember, there are specific rules which must be followed when undertaking an unsolicited email broadcast to a prospect or customer list. For example, you must include an unsubscribe option, and it must be a simple process for the individual to unsubscribe. Furthermore, any such Opt-Out requests need to be actioned quickly.

Be certain to know the rules before running your campaign.

Q – How often can I use the Marketing List?
A –
This depends on the lease / licence terms of the data, though you will always be informed beforehand.

Data is purchased under licence, effectively rented by you, which means that the data is still owned by the list owner.

A single use lease means that the list can only be once use for the purpose it was purchased, e.g. a single mailing / telephone campaign.

A “multi-use” lease means that the list can be used a number of times within the licence period. That said, you mustn’t abuse the list by emailing or calling incessantly. Any usage limitations within the licence, such as a maximum number of emails you can send, will be advised at the outset. 

Consumer data is often licensed on a specified number of uses basis, i.e. 3 x use. For example, it may be that you want to carry out 3 mailings over a set period. In those circumstances, you will likely save money overall by purchasing a 3 x use licence at the outset, rather than 3 separate single-use licences. That’s because you receive discount for buying multi-use, and for each subsequent campaign, a fresh set of data is provided at no extra cost.

Multiple mailings not only reinforce your message, but can also be more cost effective.

Q – What happens to the Marketing List once the Lease Expires?
A – Apart from those contacts who have given you their consent (as per the earlier question), you have three options:

  1. Purchase a new licence for the same data (fresh data is supplied)
  2. Purchase new data altogether
  3. Destroy/delete the data

Q – How is the List Policed?
A – 
Each List includes a “Seed”, or dummy record specific to that dataset. These can either be fictitious people/companies, or existing people/companies that have a reporting relationship with the list owner. This means that any misuse of the data can be easily identified by the list owner and attributed to the licence holder. List abuse is taken very seriously and fines may be incurred.

Q – Are Marketing Lists better than Searching the Internet, using LinkedIn or Directories?
A – Most definitely, and for many reasons including:

Less Time-consuming. It takes time to research the internet, type out names from a directory or carry out research on LinkedIn. This time could be spent contacting your prospects

Easy to use. The lists are supplied in a standard format that can be used instantly. This makes them ideal for easy mailing, email broadcasting and importing into a CRM system

There are a variety of lists available that are easily selectable and very targeted

The lists are continually updated. Not everyone updates their profile, making directories LinkedIn etc. less accurate

The lists often come with additional information such as number of employees, website, turnover or other such data

In many cases, directory information is under copyright laws, so copying it may be illegal

Contrary to what some believe, “publicly available” doesn’t mean “Opted-in”. The information available on the internet or within a directory doesn’t mean people have given consent to use it for marketing. The laws regarding marketing are very specific, so you want to be certain you’re acting within the law. Purchasing a mailing list from a reputable supplier will ensure you do just that!
