How to Make Your Email Messages Look Less Like Spam

If your email messages look too much like spam, destination mail providers might reject them or send them to the recipients’ Junk or Spam folders.

To make your email messages look less like spam:

  • In the email subject and/or content, try not to have:

    • words and phrases commonly found in spam messages;

    • an extremely short message;

    • a single paragraph that’s really long;

    • words in all uppercase when not using acronyms;

    • sentences that don’t begin with a capital letter;

    • unusual grammatical structure;

    • unusual or missing punctuation;

    • space characters immediately before commas, periods, exclamation marks, question marks, colons, and semi-colons;

    • more than one space character after commas, periods, exclamation marks, question marks, colons, and semi-colons; and

    • multiple empty lines between paragraphs.

  • Try not to include just an HTML or rich-text version of a message, without also including a fall-back plain text version in the same message.

  • Try not to send a single copy of a message to too many recipients. Instead, send a single copy per recipient, especially when it comes to newsletters, mailing lists, etc. Most mailing list apps automatically handle this for you.

  • When sending out a message for a newsletter or mailing list, always include a working unsubscribe link at the bottom of the message. Most mailing list apps can be set up to handle this for you.

Your email should now look less like spam, and is less likely to be rejected by destination mail servers or be sent to the recipients’ Junk or Spam folders.
