The UK’s largest database of email contacts

Email MarketingInsight has broken the 10,000 barrier for email contacts of window and door companies in the UK, giving clients more opportunities to target new customers than any other data supplier in Europe.

“It’s not just about the numbers though,” explains David Lewis from Insight; “it is also the most accurate. Many of our competitors bump up their numbers but a recent comparison showed a very high bounce-back rate, demonstrating the poor quality of their data.”
