My subscribers aren’t receiving my campaigns

Typically, when subscribers don’t see your email campaign in their mailboxes, it’s because of spam filters. If your recipients have viewed in their spam or junk folders and still don’t see your campaign, there are a few other things to examine.

  • Is a particular subscriber not receiving your emails? Request them to add your From email address to their contact list or address book.
  • If your From email address is in their address book, have them check their spam filter settings to be assured that your content and/or address isn’t blocked.
  • Are they using a webmail provider such as AOL, Yahoo, or Hotmail? These providers throttle delivery, which can sometimes happen in emails taking about 24 hours to be delivered to a particular email account.
  • Could there be an internal firewall? Some domains don’t like seeing emails going to and from the same domain, via a third party. For instance, you may be sending an internal company newsletter from to In the middle of that process, your email goes through a Mail250 server. Sometimes, especially with corporate and university filters, these emails look suspicious and are blocked. Review the whitelisting information if this may be the case.

If none of the above seem to get your emails to subscribers, they may need to add our IP addresses to their whitelist. Generally, only corporate domains can do this.
