Should every email have minimal text?

You've probably heard it before: keep your emails short, or spam filters will punish you. So you trim sentences, cut context, and end up sending emails that feel incomplete. Here's the thing. That rule isn't real.

There is no filter out there that penalizes long emails just because they're long. What filters actually look for is the ratio of readable text to images, signs of deceptive or spammy content, and whether your sending reputation checks out. Text length on its own is not a trigger.

The real question isn't "how short should this be?" It's "how long does this specific email need to be?"

Transactional emails (receipts, password resets, shipping confirmations) should be brief. The reader wants one thing fast. Give it to them and get out of the way. Two to four short paragraphs is almost always enough.

Marketing emails depend entirely on what you're promoting. A flash sale promo? Short and punchy. A product launch with a lot of context behind it? You've got room to tell the story. Match the length to what the reader actually needs to make a decision.

Newsletters are a different format altogether. Readers signed up expecting content, and longer issues are completely normal. A well-written 800-word newsletter is not going to get you flagged by filters. A 200-word newsletter stuffed with images and almost no text might, because filters can't analyze images the way they analyze text.

That last point is worth repeating. The issue is never too much text. The issue is too little text relative to how much image space you're using. If your email is mostly one big banner image with a single line of copy underneath, filters have almost nothing readable to evaluate. That's where the risk lives, not in writing more words.

And a practical way to think about it: if you removed all the images from your email, would the message still make sense? If yes, you're probably in a good place. If the email becomes meaningless without the visuals, you might want to add more supporting text.

Write the email your message actually needs. Don't force brevity where clarity is what serves the reader. And don't pad short messages with filler just to hit a word count. Both extremes miss the point.
