Why emails may take a long time to be delivered

When you send a campaign, Direct Mail's email servers get to work delivering your message right away. However, there are a few reasons why your message may take longer than normal to show up in your recipient's inbox:

  • Some mail servers implement "greylisting" as an anti-spam technique. This means that your recipient's mail server will reject an email the first time it sees it and wait for the originating server to resend at a later date (spammers never bother resending). Our e3 Delivery Service takes care of this automatically.
  • Your mail server is overloaded and is still working through its mail queue.
  • The recipient's mail server is overloaded and is still working through its mail queue.
