How to avoid spam filters

letter mail mailbox
Large quantities of mail are sent back and forth across the Internet, and a large amount of these are unfortunately spam. There are a variety of methods for a receiving server to determine whether an email is spam or not. Unfortunately, none of these methods are perfect and it happens that a desired newsletter still becomes marked as spam.

If a recipient haven’t received your newsletter it might be due to following reasons:

  • The email was delivered to the spam folder of the recipient, ask the recipient to see if it’s there.
  • The email was blocked by the receiving server, but they chose not to inform us about it. Some host servers choose to do this in order not to give information to spammers. Unfortunately, this means that we aren’t able to tell you that the newsletter not arrived.
  • The recipient has their mail forwarded to another address.
  • It’s the same sender and receiver for email (for example: info@domain.come both as senders and receiver).

Some things you can do to reduce the risks are:

  • Ask the receiver to put your company address in his/hers address book.
  • Do not type out entire URL-links in the newsletter. Instead, create a link in our block editor.
  • Choose your subject line wisely. Avoid using ALL CAPS, lots of space and many exclamation points!!!
  • Use our block editor which is optimized to make newsletters look good and avoid spam filters.
  • Add settings on the sending domain, which lets you inform the Internet which mail servers you actually use. Read more about it here – DKIM, SPF and Sender ID.
  • Be sure to have a good balance between text, images and links in your newsletter. Many spam filters responds to emails with many links and very little text or email with only pictures.
  • If there is still a problem, try whitelisting. This can be done on the receiving mail servers. Read more about whitelisting here.
