subject line max length for sending/tracking?

(0) ShareShare
ReportReport
Posted on by

Hello - I seem to remember reading on the forums something about the length of the subject potentially impacting e-mail send/track ability. Can you refresh my memory about the rules and caveats around this?

It looks like the default max length for the subject is 200 and the default max length for the title is 200. I think a common use case is that CRM implementors will put the full case title along with other info in the email subject.

At what length does CRM start having issues with email length? If a title is 200 characters long and then CRM appends a tracking token to the end and tries to save it then I'm assuming CRM will throw an exception via the database?

Also, replies to the email will have re: re: re:, etc, that will extend the length of the subject that gets saved. I'm assuming if the length of the original subject is 200 and the next email gets saved with "re:" in front then this will cause a CRM exception via the database?

So to manage these constraints, do you normally include, for example, the first 20 characters or so of the title in the subject line to give yourself adequate room for growth? Is there any reason why CRM would have any sending/tracking issues with an email with a total subject length <= 200?

    I too have been having an SQL error thrown when the subject is beyond 200. I did as suggested and increase the subject line (400) and saw the change reflect in the main page of the email entity but  it still throws error after 200 characters. Any thoughts?

    Hello Andrew,

    I think you should be able to change the max length of the Subject from 200 to number that you desire (Max length unknown) from Customization >>> Customize the system >>> email >>> Fields >>> Open the subject field and you should be able to change it.

    Once you change this you should see the changed number reflecting in the Primary Fields section in the Customization >>> Customize the system >>> email page.

    I just changed it and checked it,

    You may want to change it and check it as well, then if you have any issues then we can look for alternatives.

    Please let me know if this is what you were looking for.

    Thanks & Regards,

    Rob Moses

    Your first paragraph was 173 characters and needed to be wrapped to three lines. How long do you expect your case title and email subject lines to be? Is this an issue you've seen cause a problem in production, or just something you're researching out of interest?
