Clean and update your prospects email list


Step 1:

The client identifies the records in its internal database that need email appending. Once identified, this database is sent to DAI via email or FTP Upload. The database can be sent in any format, our team is equipped to handle all kinds of database formats. Once uploaded, the database is identified by DAI for processing.

Step 2:

Once received by DAI your database is formatted so that it can be matched with our Master Database of 30 million Business records with Opt-in emails. During the matching process whenever there is match found with the name, business name and address in the clients database, the corresponding email is added from our master database to the client’s database and this process will continue till the last record.

Step 3:

After the match process is over, the appended emails are verified for delivery. The verification process is semi-automated. With the help of our proprietary tools we verify all the mails for deliverability and again our data team will manually verify each appended email, ensuring our average match rates are normally over 80%.

Step 4:

At the completion of the append process step a standard message is sent to the newly appended emails confirming that the appended client wishes to communicate via email. This email gives the recipient the opportunity to Opt-in or Opt-out if they choose. After allowing 5-7 business days for all responses, the Opt-outs are removed from the database.

Step 5:

Upon the successful completion of the append process, the enhanced database is then reformatted to the original file format and it will be delivered to the Client.
