Internal Email Broadcast Best Practices Guide

Emails remain the channel most employees rely on, yet many internal broadcasts are still ignored. To help communications professionals boost attention and engagement, PoliteMail analyzed more than a billion internal emails and distilled the findings into this updated guide.

This 2025 edition of “Internal Email Broadcast Best Practices Guide” identifies the trouble spots that limit engagement and offers simple changes that can have a significant impact: from using a recognized leader’s name in the “From” line, to scheduling emails for when people are most likely to see them, to keeping messages under one minute of reading time. You’ll learn how top communicators tailor their content, time their sends and optimize their messages for today’s hybrid workforce.

You’ll learn how to:

• Increase credibility by sending from a recognized executive or specific mailbox and targeting smaller, relevant audiences.
• Get noticed with short, action-oriented subject lines and by timing your sends so they land at the top of the inbox.
• Simplify the message by keeping emails to a strict word count for higher readership, favor text over large banner graphics and include only a few well-placed links.
• Adopt proven tactics from top communicators, who balance text and images, tailor messages and optimize timing to achieve superior open, read and click rates.
• And much more.
