Enhance your marketing efforts and strengthen your customer connections
Bridge the gap between the mailbox and the inbox. Alesco’s premier Email Append services allow you to cross-reference your legacy physical customer records against our identity solutions, safely appending verified, permission-based email touchpoints to your file.
Email appends and reverse email appends are two powerful strategies that can help enhance your contact database and improve the effectiveness of your marketing efforts. The process adds missing or incomplete email addresses to your existing customer database. It matches your current customer records – names, postal addresses, phone numbers – with our premier email database to obtain the associated email addresses for those customers.
Data append success depends entirely on the scale of your provider’s core database. Because Alesco is one of the industry’s top data providers, we cross-reference your offline records against a live, continuously updated network of over 250 million consumer files and 50 million professional profiles. This structural scale ensures industry-leading match rates while maintaining strict verification standards to guarantee that every appended email record belongs to your exact customer.


By adding missing emails, you can expand your reach and the potential for conversions.


Reverse email appends involve finding additional information about your customers based on their email addresses. This process allows you to enrich your customer database with valuable details, such as names, postal addresses, phone numbers, and social profiles, among other data points.

Reverse email appends provide valuable data that enables you to understand your customers better and tailor your marketing strategies accordingly.

B2B email appending is a data enrichment process that involves adding missing or updating business email addresses to an existing B2B customer database. Our solution is particularly useful when you have a list of business contacts but lack their associated email addresses or have outdated email information.


All files are handled within tightly monitored, secure environments using end-to-end encryption. Appended matches rely exclusively on permission-based, opt-in data repositories aligned with current consumer privacy protocols.
