Ensure universal email readability with automatic non-ASCII character detection and replacement.
Campaign Cleaner automatically scans your email for non-ASCII characters and replaces them with safe ASCII equivalents, preventing encoding errors and compatibility issues before your campaign goes out.
Quick Overview of Features
ASCII (American Standard Code for Information Interchange) defines 128 characters - the letters A through Z in upper and lower case, the digits 0 through 9, and common punctuation marks like periods, commas, and question marks. These 128 characters cover everything needed to write standard English text. Non-ASCII characters are anything outside that set: accented vowels like e with an accent or n with a tilde, curly quotation marks, em dashes, ellipsis characters, the copyright and trademark symbols, and characters from non-Latin writing systems. While these characters are perfectly valid in modern Unicode text, they require extra care in email because the email transmission infrastructure was originally designed around 7-bit ASCII.
The most common source is copy-pasted content from word processors. Microsoft Word, Google Docs, and Apple Pages all apply automatic typography corrections as you type - converting straight quotes to curly quotes, double hyphens to em dashes, and three periods to an ellipsis character. When writers paste content from these applications into an email editor, these typographic characters come along with the text. Other sources include email templates built by designers using extended character keyboards, content imported from databases with extended character sets, and subject lines drafted on mobile devices that apply their own auto-corrections.
Non-ASCII characters affect inbox placement through two mechanisms:
When a non-ASCII character is transmitted or rendered incorrectly, it appears as a replacement character - typically a question mark inside a diamond shape, a series of garbled accented letters, or a blank box. A subject line like "Here's what's new this week" might render as "Here's what�s new this week" on a system that misinterprets the encoding of the apostrophe. Recipients see this as a broken, untrustworthy message and are significantly less likely to open it. For transactional emails, encoding errors can make critical information like order details or account notices unreadable.
Campaign Cleaner scans the full content of your email - subject line, from name, preheader, HTML body, and plain-text version - for any non-ASCII characters and replaces them with their closest ASCII equivalents. Common replacements include:
