The economic arguments for appending emails to your database

Why should you invest in email appending for your business?

Email was described as the “killer app” of the Internet – the function which justified investing in a computer and an online connection for both individuals.

Of all forms of marketing, it generates the highest return on investment – outperforming social media marketing, content marketing, telemarketing, and more.

But like all other forms of marketing, reach is vital. If you have 10,000 decision makers names – people whose business, school, or public sector organisation need your products and services – but only 3,000 email addresses, there are 7,000 opportunities to connect with and to pitch decision makers you’re missing.

Email appending with quality safeguards

With email appending, we look for the direct contact addresses for those 7,000 decision makers whose emails you currently don’t have.

Where do we look? We look not only on our extensive in-house database but we also examine the multiple substantial marketing and contact databases of a handful of carefully-selected media partners.

When choosing our media partners, we make sure they have the same commitment to quality over quantity that we have. We ensure that their data protection and GDPR policies are robust and that they’re observed in every business process they undertake.

And within a day or two following an initial check and multiple re-checks, we deliver your marketing databases back to you with far more usable, valid email addresses than they had when you sent them to us.

Email appending unlocks missing revenue

Nothing will generate leads and sales faster than email marketing.

Within a few short weeks – within three email campaigns to your new addresses – you’ll realise the revenue you’ve been missing because you were unable to contact existing and potential clients using this most effective and profitable of marketing approaches.

If you’re new to email marketing or you have been using it but you feel that you’ve not been generating enough new leads and sales from it, your account manager together with the advertising support team will be able to help you. Just send them what you want to send to the decision makers on your marketing databases and we’ll get back to you (normally within 24 hours) with suggestions and feedback.

What type of data can we cleanse?

We specialise in cleaning the following three types of marketing database:

  • customer databases – databases of businesses, schools, and public sector organisations which have bought from you,
  • prospect databases – databases of businesses, schools, and public sector organisations which have been in touch with you but which have not bought from you yet, and
  • bought-in marketing databases – databases of businesses, schools, and public sector organisations whose details you have purchased from a 3rd party source like a list owner or a list broker.

Please note that we are unable to append email to any B2C marketing database or to any overseas (non-UK) database of contacts.

Missing other details?

Are you missing other information on your database like contact names, postal addresses, phone numbers, and more? Does the age of the data you have concern you and would you like us to check if the details on your record are generally complete?

We’re able not only to check most of the fields on your database but, subject to your instructions, we can replace what’s on your database with the latest information. Speak to one of our account managers to find out more.

Email appending benefits

What is email appending?

Email appending (sometimes known as email address appending) is a process by which email addresses are added to information records on a database where there is currently no email address.

There are three different types of email appending we offer:

  • B2B email appending (sometimes called business email appending),
  • education email appending, and
  • public sector email appending

With our B2B email appending services, we take a client’s customer database, prospect database, and bought-in business marketing databases and, when an email address field is empty, we cross-check it against our B2B email database and the email databases of our media partners to check to see if we or they have the information. If we or they do, we then add the email address to that particular record.

The same process applies for our education email appending and public sector email appending.

Our marketing databases cover the UK only – we do not offer email appending services for B2B, school, or public sector databases for other countries.

Why is email appending important?

What are the main advantages of email appending? Of all types of direct marketing, email marketing produces the greatest return on financial investment. In addition, organising, dispatching, and monitoring an email campaign is a lot less labour-intensive and expensive than telemarketing or postal marketing.

As with all other types of direct marketing, the number of leads you generate and sales you make are partly dependent on the accuracy of the data you hold and the number of email addresses. The more email addresses you hold, the more opportunities you have to provoke a positive response from clients.

By appending email addresses to your customer, prospect, and bought-in lists, you give your marketing team more targets to communicate with and their efforts will create more closing opportunities for your sales team.

How do you carry out email appending projects for your clients?

When contacting us, clients ask us how do email appending companies append the databases they work on for clients?

All email appending companies use the same set of email appending techniques. What determines the success of your outcome is the quality and depth of the databases against which your databases are compared.

For example, More Than Words’ marketing databases contain over 650,000 email addresses all of which are thoroughly researched and GDPR-compliant. If you used an email appending company with marketing databases containing just 400,000 email addresses, you would be more likely to get fewer positive matches from them – in other words, your marketing team wouldn’t have as many email addresses to work with compared to the results our service would provide you with.

Email Appending FAQ

With reverse email append, we add company names, decision-makers names and job titles, postal addresses, telephone numbers, fax numbers and more to your marketing database – it’s the exact opposite of appending emails.


We offer reverse email appending on B2B, school, and public sector contact and marketing databases. To ask us about reverse email appending, please call us on 0330 010 8300 or you can click here to email us.

The cost of our email appending service (or reverse email append service) depends on the volume of data which needs to be processed and the amount of information we’re able to add to your database.

To give you a rough guide, the least expensive data to email append is schools data followed by B2B data followed by public sector data.

Your account manager will be able to provide you with a full count and quote when you contact us and after our data team has run a preliminary assessment.

The best practices for email appending (and reverse email append) are focused on the following two areas:

  • the quality of the databases which are used to cross-reference against the databases you provide us with and
  • the commitment of an email appending service provider to confidentiality.

For More Than Words’ clients, we only append (or reverse append) databases of companies, schools, and public sector organisations based in the United Kingdom. Our data team is fully conversant with all applicable laws surrounding the gathering and processing of information pertaining to decision makers acting in their professional capacity.

Second, most of the databases we’re sent contains genuine supporting information of value to our clients – ordering details, call handler notes, and so on. It’s absolutely imperative that the confidentiality of this data is respected and protected. Following the completion of our work for you, your database(s) is/are removed in its/their entirety from our systems for further protection.

Yes – many of our email appending clients ask us to perform email verification services at the same time.

Email verification involves checking the email addresses which do exist on your database(s) against our databases and our media partners’ databases. Particularly on older customer, prospect, and bought-in databases, the likelihood of significant decay is high and clients ask us to replace the email addresses they hold with the email addresses we and our data partners hold.

In addition to replacing out-of-date email data, we’re also able to replace other data on the company or organisation, the decision maker names, details of the business or organisation they work for, and so on.

Tell us what you want from your databases. Please call us on 0330 010 8300 or you can click here to email us.

Yes – we have an in-house telemarketing team who can verify and append email data in live conversation with decision makers. At the same time, we can also pitch your products and services to those decision makers and we can gather general and specific market intelligence when on the phone.

When you contact us, please ask us for our telemarketing team to discuss your project.

Yes. As we offer accuracy guarantees on the B2B email database, school email address list, and public sector email addresses we sell to clients, we also offer accuracy guarantees on the quality of contact information on our email appending service.

For more information about our accuracy guarantees, please call us on 0330 010 8300 or you can click here to email us.

The best email appending services always observe and align to applicable legal and ethical guidelines to protect both the client and the decision makers with the companies and organisations they’ll be contacting.

Under GDPR, it is illegal to contact sole traders and partners within unincorporated partnerships without their explicit consent and a valid reason under the legislation even for business purposes. We will not append the email addresses of unincorporated businesses to your email address.

We will also seek assurances from you that you will only send marketing information on products and services to the decision makers whose email addresses we append or verify which benefit the organisations they represent and work for.

As an example, we would not append email addresses to a database for an insurance company if they intended to use those email addresses to sell life insurance because the insurance policy they sell does not directly benefit the business or organisation.

However, we would append and verify email addresses if an insurance company intended to use the email addresses to market key person insurance or public liability insurance, for example.

Email appending tools are clever in that they automate many of the processes used by traditional marketing database providers. This automation leads to often significant savings.

However, email appending software tends to use old data to match records against and the age of that data will often mean that a significant number of the appended email addresses will be unusable. They may also use webscraping techniques which will leave your company prone to spamtrapping and they may harvest data from LinkedIn and other social media platforms which, in most countries, is illegal.

By all means you should investigate what’s on offer to find the best and most cost effective solution but you should always verify which databases are being used to append email addresses before making a commitment to one supplier.
