Page 1 of 2 In an understandable attempt to eliminate annoying spam, over-zealous email filters can often inadvertently dump emails that you want to receive, including newsletter subscription requests or important emails or replies that you requested. Even 3D Inspection System users occasionally contact us saying they never received a recent software subscription or reply to a question they sent us. When subsequent resends or replies back are also dumped unceremoniously by their email, this compounds the problem of reaching them. How can you “whitelist” emails you want to receive?
What is a whitelist?
Many spam filters that come with email clients have both white and black (or block) lists of senders to check for in emails. Your "whitelist" is the list that contains the email addresses of those you do in fact deem acceptable to receive email from and do not want to automatically go to the trash folder. Some services simply require accepted addresses be in one’s address book, while others require that you manually add addresses to a particular "approved", “safe”, or "allowed senders" list. If a white list is exclusive, only email from those on the white list will get through. If it is not exclusive, it prevents email from being deleted or sent to the junk mail folder by the spam filter.
Regardless of what the feature is called, mail from the listed email addresses, domains, and/or IP address on such a whitelist should always be allowed through. Some Internet service providers also sometimes use whitelists to filter incoming email, but it’s usually end-users that set spam filters to actually delete all emails from sources not on the white list. Using whitelists and blacklists can certainly assist in blocking unwanted messages and allowing wanted messages to get through, but they are not perfect. So email whitelists can greatly reduce the incidence of false positives (items dumped as junk when they are not) by assuming that most of your legitimate mail will be from a relatively small known group of senders.
Best practices and whitelist etiquette
When signing up for an online newsletter, mailing list or Web site service, immediately add their email address or dot com domain to your approved or white list. This will ensure smooth communications with you and that emails will get through with the information you requested or confirmations necessary for you to acknowledge your request.
 If you initiate a request for contact, it is your responsibility to promptly add the other side’s email address or domain information to your whitelist. This courteous step prevents those from whom you have requested information or services from being annoyed by having to follow special verification email instructions just to get you the information that you requested. Don’t count on everyone responding to automatic verification emails, if such are even sent out from your email, as many simply don’t or can’t (automated subscription systems).
Before getting upset because you believe someone didn’t respond, check to see if their email was inadvertently deleted or sent to your Trash, Junk, or Spam folder. Upon finding any such emails in those folders, add their information to your whitelist immediately. Why look like a jerk by becoming belligerent about a supposed lack of response when in fact a response was sent and you just didn’t clear the way for the email to be accepted or allowed through. Don’t make email inconvenient, but allow it to be efficient communication tool everyone will appreciate.
Whitelisting and contacting 3D Inspection Systems
To ensure that your emails reach 3D Inspection Systems, use the contact forms on our website. Since 3D web contact forms get sent to us from our own domain they won’t get filtered out as could happen with a direct email, not to mention contact initiated through 3D’s web forms also receive top priority over general emails.
 To ensure you don't miss out on subscription upgrades or replies from 3D Inspection System technical support or main sales office, you should "whitelist" our main email addresses shown here or the general 3dinspection.com domain.
