  • Define Columns. We will show a preview of the uploaded file, where you will tell us which column contains email addresses.
  • Review and Submit Your Order. We will show the processing cost, based on selected service and record count. Then, depending on the file size, you may be given one of the two options or both:
    • Process Now - Wait for processing to complete, keeping the page open (5 seconds to 30 minutes).
    • Schedule Processing - OK to close browser or use other SearchBug tools. You will receive email when file is ready (same or next day).

  • Payment. This step a bit diffrent for exsting or new users.
    • Existing users with a regular Pay-As-You-Go account; your saved credit card will be authorized for the shown amount. After your file is complete, we will use that authorization to charge your card.
    • Existing users with a Prepaid account; your account balance will be used for the full payment.
    • New Users will be asked to sign up and provide a credit card. It's a quick one-page registration process. Our system will authorize your credit card and charge it when your results are ready.

  • First, we verify if domain (e.g. in exist, registered and valid.
  • Second, we contact nameserver for the domain to find if MX record exist. MX Record tells that that there is a mail server to recieve incoming messages for the domain.
  • Finally, we do a "hand-hake" with the Mail Server, asking if it will accept the message to the specified address. This is exactly what happens when you send actual email.

  • Cost is based on number of records in your file and it goes down significantly with larger volumes.
  • Cost range is from 5 to 0.5 cents per email, depending on volume. Volume tiers start at 100, 1,000 and 5,000.
