Common questions about newsletter length and reading time
How long should an email newsletter be?
It depends on the audience. Promotional and B2C emails perform best around 75 to 150 words, B2B newsletters do well at 150 to 250 words, and creator or personal newsletters often run 500 to 1,000 words. Research from email platforms shows emails near 200 words consistently get the highest click-through rates.
What is the ideal word count for a B2B vs B2C newsletter?
B2B newsletters typically land between 150 and 250 words because the audience scans for value during a busy workday. B2C and consumer emails work best at 75 to 150 words, where a single offer or story can be read in under a minute on mobile.
Does shorter newsletter length really get higher click-through rates?
Yes for most promotional sends. Studies of email engagement consistently show that emails around 200 words or fewer earn the highest click-through rates because readers can finish them on mobile and act on a single CTA. Long-form editorial newsletters are an exception and reward depth.
How do I calculate newsletter reading time?
Divide the word count by 250 words per minute, the typical adult reading speed for email and screen content. A 250-word newsletter takes about one minute to read; a 500-word newsletter takes two minutes. This tool calculates reading time automatically as you type.
What is a good newsletter length for Substack or Beehiiv creators?
Creator and personal newsletters typically perform best between 500 and 1,000 words, which is long enough to develop a voice and deliver insight without losing weekly readers. Long-form editorial issues can run 1,000 to 2,000 words when the audience expects depth.
