We regret we do not send out free samples.  However, you can view example records on the Home or Introduction page of the list in question.  Also we do provide the best guarantees in the industry regarding deliverability. Please see the Business Terms Page.
We do not charge VAT but we will send you an invoice after payment upon request.
We urge you to save your list purchases in a safe place after downloading and to guard against data loss by making copies. We can re-send download links but we only keep lists for a maximum of 4-6 months. After that, you will need to purchase the latest version although we can provide a 50% discount if you purchased that list previously.
Are you trying to pay with a corporate credit card?  If so, some corporate cards as well as certain other cards with no spending limits seem to be have restrictions at Paypal’s IPN system (Instant Payment Notification) set by the Credit Card Issuer.  You will need to check that with your card issuer. The alternatives are to use another credit card or we can accept a bank transfer which usually take a couple of days to clear.
File will not download: It might be that file delivery service was off-line for a few moments or there was a break in the connection. Please try it again. If the problem persists then please send us a screenshot of any errors you see.
Also if the Download link has arrived in your Spam Folder please move the e-mail  to your Inbox. Then try again and click on the red VIEW FILES icon in the Hightail message and choose SAVE FILE.
We also suggest to try these troubleshooting steps below as workarounds and see if the following will help:
Please clear the cache and cookies, close the browser you’re using, re-open it and then log back in Hightail and download the files.

File will not open properly: If you have already downloaded the file and it does not open properly then please advise what program you are trying to open it with and if you are using a MAC or Microsoft. A screenshot or errors would also help us to better understand the issue. Many MAC users are unable to open .csv files without all the data appearing in just one column – but we have a simple work around for this problem – just save the csv as an Excel Workbook  or request us to do this and send the file to you again.  You should then be able to open and read the file without further problems.


It is possible there are duplicate website addresses or business names in each list as we often supply more than one unique email address at each website address but there are no duplicate email addresses in any of our individual lists.
However, if you plan to purchase MORE than one closely related list ( for example; List of Restaurants and List of Bars) in this case there might be a limited number of duplicate email addresses. Contact us for more details, letting us know the lists of interest.
Email addresses in our Lists include both generic (usually around 40% of the total) and non generic addresses. All email addresses are researched from the businesses website address. See the “Research Methods” page for more details.
Unless stated otherwise on our websites we only offer Country wide Lists. However, we do understand that many of our customers only require data from a certain geographical area – that is one of the the reasons that we price our country wide lists as such competitive levels. Therefore we hope that a list purchase will still prove to be worthwhile even if data is only required from a limited geographical area.

We do not include job titles or contact names (although many of the email addresses listed contain a named contact, example: Please understand you will find it impossible to obtain genuine and up to date Lists or Directories with contact names at our price point as the only way to keep such contact names up to date is to telephone the organizations every few months to check the contact information which is obviously an expensive process resulting in finished data which is then sold at far higher prices. Please be wary of any seemingly similar lists at our price point with contact names as the maths simply does not add up.
To see details of the data that our lists contain please see the Home or Introduction Page of the list in question.  You can also view a screenshot video on that web page that shows exactly the type of data that is included. As you will see we do not mention that we supply Contact Names or Job Titles.
This point is also covered in the Shopping Cart where the order is placed and in our Terms of Business Point 4
Our Data is different! We use the web to manually research and verify all the records held in our database.
Using search engine techniques, conventional mailing lists and other relevant business data our dedicated off shore research team manually searches on the web to find each business listed. When found they visit that firm’s website to confirm and verify details such as business activities and other relevant data such as email address.Then every few months in order to keep the resulting data up to date we send a verification email to all the addresses in our database and we simply delete out the addresses that bounce and amend records accordingly. In addition many of our lists include CASS (USA lists) or PAF (UK lists) verified postal addresses.
By comparison, most competing lists are compiled simply by keying unverified information from published sources of information such as public records, telephone books or trade directories. That is why those types of lists are so inaccurate and out of date! After all, when was the last time you updated your business details in such publications? On the other hand, anyone who is seriously in businesses keeps contact information on their website up to date.
So there can be little doubt that the web is going to provide the most accurate and up to the minute business data. That is why all our directories and lists have been painstakingly researched and verified via web research methods. However, the email addresses listed are not transactional nor so called opt in – please see our Terms page for details of our email delivery guarantee.
UK and EU : To comply with current GDPR regulations only details of limited companies, government bodies, PLC’s and other corporate’s are included in our UK and EU email lists and we do not include contact names. Free type email addresses (such as Gmail, Yahoo, Hotmail etc) as well as email addresses at telecoms services (such as BT, Virgin, Talktalk etc) are also not included in any of our UK or EU Lists.
Unless mentioned otherwise on the website that is generally not possible. However, please check back to the website/list of interest for more information and view a wide range of sample data.
No. Lists are sold on a one off basis only.  Updated lists are offered to previous buyers from time to time at discount rates.

Yes there are a number of poor quality lists in the marketplace.
Firstly, before buying ANY product online especially mailing lists or other digital products we advise you to carry out due diligence via the web prior to purchase. Visit respected sites such as the Better Business Bureau or the Rip Off Report and search for company and product name/type to see if there have been complaints. Do the same via major search engines such as Google – search for company or product name followed by words such as complaint, scam, rip off etc. You will not have to search for long to discover the vendors to avoid.
Please note that most of the bad guys have been kicked off Paypal which is more or less the industry standard for merchants selling digital products. Buying via Paypal offers a great deal of buyer security and they review the accounts of merchants that generate a certain number of complaints. So you might notice that the bad guys often only offer very limited payment options which you should consider to be red flag. However, should you find other List vendors offering a Paypal payment option then check to see if the Paypal merchant name is in the name of an individual or a corporation or company and of course check the vendors Business Terms to see if they offer a meaning  guarantee  (Please note that we have been a Paypal merchant since 2008 and that we are a company)
Secondly, please see
Thirdly, please read our Terms where you will discover the best and most meaningful guarantee in the industry!

Are your Lists “ Opt In”
No but please understand  there really is no such thing as a truly valid purchased opt-in email list.  The only valid optin list is a list created from contacts that have opted-in to receive details of YOUR products or services. So called “Opt in” lists sold by other list suppliers are usually supplied on the basis that those listed have ‘opted in’ to received commercial messages via email. This basically means, any message, from any sender!  But while some of those listed might have agreed to receive email messages concerning a very specific subject, from a very specific supplier, most never agreed to receive email messages from any other third party.Therefore, if you are offered so called ‘opt in’ lists from other list suppliers you will need to follow up to see exactly what proof of an opt in they can provide.


UK and EU customers should also check out the new regulations on “Opt in” lists which we summarize at

As per our Terms and as mentioned on other pages on our websites such as the “Sending Email” page some email delivery services such as Constant Contact, Mail Chimp, (Mailchimp) SendGrid, Aweber, Vertical Response and others have stricter rules and stricter enforcement of those rules than others. Some services, but not all insist you cannot email to a purchased list and that you can only email out to a “transactional” list – which means you must already have an established relationship with the recipients. Clearly, our lists do not meet that requirement and what some email delivery services will or will not send is beyond our control. If you are unclear on this point please see our Terms of Business for further details but if you need help in locating a suitable email delivery service that will send messages to our lists then please visit:- Email Marketing Tips or contact Clickback the market leader in sending email to a purchased list.  For full details see
We no longer provide pre-sale telephone support and now request that customers contact us by email instead. Last year virtually all customers found the information they require on our websites either without the need to firstly contact us or by firstly contacting us by email. All such email inquiries are answered in a timely manner by one of our managers.
The requirement to properly and expertly answer a tiny number of pre-sale telephone inquiries in all the time zones in which we operate (USA, Europe & Australia) adds significantly to our costs and ultimately these costs must get passed on in the form of higher prices. So instead we would prefer to keep our very reasonable prices as low as possible by responding to questions by email only.
You will also find that most customer questions are answered in our easily searchable FAQ file at
Thank you for your understanding.
We are sorry to hear about the problems you are experiencing with bounces but please be assured that we send email messages to those listed every few months and then simply take out the hard bounces.  Of course data does decay quickly but I would be disappointed if the rate of hard bounces in the supplied list exceeds 5%.​​
Could you please provide more details on how you are sending out your email messages?  Our Terms specify that you should use a professional email delivery service and such email delivery services will provide precise details on the cause of each bounced email and will provide you with a file that contains the bounces with precise reasons for the bounce. 
Could you please send us that file of bounces so we can check further?
Also as per our Terms see we do give proportionate refunds for Hard Bounces but firstly please advise what type of bounces you are getting please? Hard Bounces or Soft Bounces?.
Hard Bounces (examples: “User unknown”, “Account does not exist,” “domain does not exist,” “mailbox does not exist”) These type of addresses are definitely not going to get delivered and should be deleted from your database. We will always refund for these types of bounces.
Soft Bounces (examples: “user over quota,” “mailbox full”, “blocked**”,  “time outs”  or a temporary issue with the recipient server, for example if their DNS server is down) These types of bounces are beyond our control. But these types addresses will usually be deliverable at a later date or deliverable via a different method.  Email addresses that soft bounce are still valuable and should not be removed from the list.
However should you be getting an excessive number of bounces then the reason is highly likely to be because your email messages were not sent  or were blocked by your service or email delivery system in the first place.
Here are some of the many reasons that emails are not sent or are blocked:

Connection Timed Out– First of all, check that your firewall isn’t restricting your emails from being sent.

Too Many Connections-  You’ll need to check that your concurrent connections setting isn’t set to any higher than this.

450 DNS Lookup Fail-  If there is an issue here, you’ll need to speak to your DNS provider .

Suspected spam message rejected This error is sometimes generated by emails sent to certain servers . You may need to adjust your content

This email matches a profile the Internet community may consider spam. Please revise your message before resending.- It may be that something in the body of your email triggered a spam filtering software to reject your message. We recommend testing the content of your email using Mail-Tester.  Body content that triggers spam filters may include too many capitalised words, poor grammar and or spelling, overuse of punctuation, lack of an unsubscribe link or incorrect HTML links.

No immediate delivery: load average- The sending  server is overworked

521 Error.- It is possible that your email is too spam-like or that your IP address is on a blacklist. Try testing your email content using Mail-Tester.

550 You are not allowed to send from the email address you are sending from.

550 5.7.750 Error – Service unavailable / Client blocked from sending from unregistered domains- Check to see if your IP address or domain is blacklisted.

554 Error – message/partial not supported/ 554 5.6.1 Messages of type message/partial are not supported-

SMTP record- This is normally an issue with the sender domain’s SPF record. Check the SPF record for the sending domain .

Put into go slow queue- If you see this error, it means that the recipient server has requested that we delay or slow down sending. The email will be sent within the next 30 minutes. In the meantime, please check your SPF and DKIM records to ensure that they are set up correctly as this can often trigger the issue.

Maximum line length exceeded Please update your DKIM record. You can also turn on the unsubscribe footer

We’ve found lots of messages from If you see this error it may suggest an IP senders reputation issue.

550 relay access denied – please authenticate- Please ensure that your SPF record and DKIM record are up to date

I have found APC Services Ltd in the UK but this does not match with your company activities.
Unfortunately there is a company based in the UK with the same name as us. The company referred to has nothing to do with us, either now or in the past. Please see the ‘’About Us’ page on our website for our company details.
Please understand that we send an email message to all those listed every few months and then take out the hard bounces. If there was an easier, cheaper and equally accurate way to check our data (such as verification services where an email is not actually sent ) then we would of course be using such a system as this would save us a very considerable amount of money each year.
The reason that we do not use Email Verification services is that after testing many such services they produced VERY different and mostly unreliable results. So we only provide refunds for hard bounces where an email has actually been sent.
Best Solution:  Try a different Browser.
This foreign language  problem sometimes occurs at Paypal – we are not sure why but usually an English language link will be given at the bottom of the Paypal screen even if most of the page is in a language other than English.


One possible answer is that the last time you purchased at Paypal you were sent to a  non English version of Paypal and that link or cookie has stuck in your cache. Clearing the cache might resolve that issue.


Alternatively please try a different browser.


For the delivery of a Download Link to your purchase please provide an email address in the APC Lists Shopping Cart that is connected to an established business website domain (eg:

We cannot send Download Links to the following other types of email addresses including:-

~Free type email addresses (example; Gmail, Yahoo, Hotmail etc )

~Email Addresses provided by telecom or web services (example; Comcast, icloud etc)

~Email Addresses connected to a new (less than 3 months old) , ‘under construction’ or ‘coming soon’ website.

If you are are unable to comply with the above requirements then please contact us at for a possible work around ( BEFORE making your payment to us)

So why the fuss?

Best solution: Use a different browser and then try and make the purchase again.


When you Check Out from our Shopping Cart you will be taken to Paypal where you should see the Credit Card payment option on the first screen. If not, please continue as a “Guest” to get to the Credit  Card payment option.  If that Guest option is not shown then your current browser might have collected unwanted cookies from Paypal preventing this payment option from being shown.  The best solution is to use a different browser and then try and make the purchase again.
Please see for more information.
