I'm finding that our email messages are frequently getting clipped/cut off in Gmail because of html file size. I found some info here saying Gmail clips messages over 102Kb:


However, I have no way of testing or knowing if my emails are too big (over 102Kb) before sending them. This clipping does not get reflected in the test emails that I send to my personal account.


Can Constant Contact please add a feature to indicate the html file size, or a warning if our emails are too big? Other services like - have an Inbox Preview feature.


And if there's a way to do this that I'm missing, please let me know. Thank you!


Thank you!



Re: Please add email HTML file size

Hello @ChristineF75,


Thank you for bringing your question to the Community!


I am sorry to hear that you are running into this issue. As you have mentioned, email messages will be clipped when they are greater than 102Kb on that web mail client. Click Here for our support article that goes over this topic.


That said, sending your email as a test should let you know if your email is being clipped. If this is not happening then I would want to look further into this for you. Please send an email with a mention of this post to social_support(at)constantcontact(dot)com with the following information:



Name of the email campaign:


Finally, I have passed along your feedback to our development team. I let them know that you would like a feature that warns you when your email goes above the 102KB threshold. We really appreciate the feedback!


Thanks again for reaching out! Have a great day!

Re: Please add email HTML file size

It has been a year since this request. I have the same issue. Has it been resolved? Can we see the html file size so that we know that our message is within Gmail's 102kb limit?
