Database and digital marketing specialist Cyance has increased its online marketing database by 1.5 million permission based email addresses.

The data specialist is already the UK's largest B2B email resource; the latest developments have increased it by 50 per cent. The service it has called ‘Email Base' is designed to offer unrivalled deliverability results due to the large amount of data and its cleansing service.

It highlights old domain names and identifies generic prefixes in email addresses. Cyance says users are provided with a consultancy experience to ensure they get the most out of the data.

Steve Kemish, director of Cyance says, "We are committed to developing and growing our database and are therefore delighted that we have already expanded our Email Base by 50 percent since the launch of the product only three months ago."
