A newsletter goes out to many inboxes, each rendering text a little differently. Hidden characters and messy formatting that look fine as you write can break in a subscriber's client. Here is a simple pre-send routine.
Why newsletters are especially sensitive
Unlike a document you control, a newsletter is rendered by dozens of different email clients, on different devices, with different defaults. A single invisible character or non-breaking space that survives into your send can show up as a box or an odd gap for a chunk of your list. And because it is public and archived, a broken character sticks around.
The pre-send cleaning routine
- Draft wherever you like (a doc, a chatbot, a notes app).
- Clean the text. Paste it into a cleaner that strips invisible characters, normalizes non-breaking and exotic spaces, straightens smart quotes, and handles em dashes. textscrubr does this in your browser while keeping your headings and lists.
- Paste the clean version into your newsletter tool.
- Do a final clean pass if you edited in a separate document afterward, since word processors reintroduce smart quotes and non-breaking spaces.
- Send yourself a test and check it on both a desktop and a mobile client before the full send.
Keep your structure
A newsletter usually has headings, lists, and links. A structure-aware cleaner keeps those intact while removing the noise, so your clean text still pastes as a properly formatted email rather than a wall of text.
Beyond characters
Cleaning handles the mechanical issues. For a newsletter people actually read, also write in your own voice: vary the rhythm, cut filler, and lead with something specific. Clean formatting plus real substance is what makes an issue land.
Why it is worth the minute
A minute of cleaning before each send prevents broken characters across your whole list, keeps your archive clean, and makes every issue look intentional and professional.
