By implementing a robust data enrichment and email validation process, you can dramatically increase your targeting options and improve the quality of data and reduce your annual cost of Mailchimp.
Since Mailchimp is licensed by the number of records stored in the database, it's crucial to integrate Mailchimp with a data quality solution that would be continuously enriching new and existing records, as well as identifying invalid records that need to be removed to free up extra space.
Be careful though, legacy third-party data enrichment and email validation tools for Mailchimp demonstrate 55-60% match rate. The reason for such poor match rates is that those tools are only capable of enriching records in real time. That means that if there was no match between your records and their database, you won't get your records enriched.
MARCOM Robot is not just enriching your data and validating email addresses and phone numbers for your leads and contacts stored in Marketo in real time. It keeps track of all records that we haven't found a match for right away. Then it makes a re-crawl and updates your remaining records within 48 hours. As the result, your match rates are upwards of 90%, which is unheard of in the industry.
