The benefits of data cleansing for email marketing

Increase email engagement

Increase the accuracy of personalisation with email messages that compel clicks, generate replies and fuel your sales pipeline.

Avoid being spam filtered

By cleansing email data, you can identify and remove invalid emails, thereby reducing email bounces and ensuring your email marketing messages consistently hit the inbox and avoid landing in the spam folder.

Create a single customer view

Merge disparate and disconnected customer data into one unified customer database to have a joined up view of customers and increase the depth and accuracy of personalisation.

Most businesses are unaware that sending emails to invalid or inaccurate email addresses can result in all future emails being filtered into the spam box. Cleansing email data helps businesses remove invalid emails so they can maintain their email sender reputation and can focus on hitting the inbox every time

Email data degrades over time as people change jobs and errors like duplicated records, malformed emails, non alphanumeric data and unstructured email can cause havoc within marketing campaigns. Data cleansing focuses on rigorously scrubbing out these errors and enhancing email databases with fully enriched data, enabling more sophisticated personalisation and effective email marketing campaigns.
