MailBluster allows a maximum email content size of 120 KB. If your email exceeds this limit, you will encounter the error message.
To ensure optimal delivery and avoid issues, it’s generally recommended to keep your email content between 15 KB and 100 KB.
For instance, Gmail has a 102 KB limit, after which any additional content is clipped and hidden behind a ‘view entire message‘ link.
By keeping your emails within these guidelines, you can help ensure that your content is fully visible to your recipients.
