WhiteListing of Domains on Subscriber End

Private email domains tend to have more aggressive firewalls and spam filters than Gmail or other free webmail providers. Sometimes, these network firewalls and filters can block your campaigns.

If subscribers from a certain company or private email domain have trouble receiving your EmailMerge campaigns, ask them to whitelist your email account as a possible solution.

In this article, you’ll learn about whitelisting.

When to Whitelist

Before you ask subscribers to whitelist your email account, review these questions to see if private domain settings might be responsible for delivery issues.

  • Do all people with addresses at a certain private email domain, like @hathaway.edu or @radicalgadget.com, have trouble receiving campaigns or messages from your email account?
  • Did affected subscribers check their spam or junk folders and still not see your campaign or message?
  • Have affected subscribers at the domain allowed enough time for campaigns or messages to arrive?
If you answered yes to all three questions, whitelisting might help deliverability at the affected domain.

How to Whitelist

To improve delivery with whitelisting, an IT professional at the affected domain will need to change the configuration of the receiving email server to accept mail from your email account.

Here’s how you can start the process.


  • Contact an affected subscriber to explain that a network firewall or spam filter at their domain could be blocking EmailMerge campaigns sent from your email account.
  • The IT professional should thenadd your email into safe senders list and ensure that mails are now coming through.
