求翻译：对于较为复杂的问题，多个收件人频繁回复，发表看法，把邮件越RE越高，这将导致邮件过于冗长笨拙而不可阅读。此时应即是对之前讨论的结果进行小结，删减瘦身，突出有用信息是什么意思？

For the more complex issues, multiple recipients, frequent reply, comment, mail the more re the higher, which will cause messages to be too lengthy and unwieldy and unreadable. Shall be discussed before the results summary, deletion of thin, highlighting useful information
