What to do if your email is blocked or bounces

Email Blocked or Bounced? What to do if you can't email Aartech

If your email is bouncing or blocked when trying to reach our staff, sales or support helpdesk addresses, it's typically one of two issues:
  1. Email content or attachment is prohibited or triggering spam filters, or your email domain is flagged for SPAM
  2. Problem with your SPF, DKIM or DMARC record or similar issues with your email server set up.

With the influx of SPAM, phishing attacks, spoofing and malware our mail system may reject emails if they are on a spam list, bad history, or have incorrect setup.  If the emails are simply going to SPAM our staff can check for those.  If you're seeing a BOUNCE or POLICY VIOLATION error then it's a larger problem that will need to be addressed.  The bounce message will provide details about the problem.  If it's a SPF or DMARC error you'll need to work with your email provider or IT department to correct the issue.

If you're not sure you can try sending the message to us from your Gmail, Yahoo, Hotmail, Outlook or Live email address and see if it gets through.  In fact you can forward us the error message if you're not sure what it means and we'll try to help you.

As of 2024, all the large email service providers are demanding senders set up their email records correctly to avoid deliverability problems.  You can see some background here:


For email senders, it's critical to set up email records correctly to protect your domain against hijacking, spoofing, and reputational damage.
