If you draft a post and encounter a "Post too long for email" notification, it indicates that the content might appear clipped or truncated in a recipient's email inbox.
Although there are no word count or length restrictions for blog posts, some email providers, such as Gmail, may truncate messages that exceed 102KB.
This message will appear in the blog editor once the size limit is surpassed. However, you'll still have the option to publish the post.
