What Is an Email Formatter?
An email formatter cleans and normalizes messy email lists so they are ready to import into your CRM, email platform, or marketing tool. Real-world email lists often contain extra spaces, double @ symbols, inconsistent separators, and other formatting errors that cause import failures or silent delivery issues.
This free tool handles all of that automatically. Paste your raw list — however messy — and it will strip whitespace, fix common typos, validate each address, and output a clean comma-separated list. It is ideal for marketers cleaning up exported data, developers normalizing user input, and small business owners preparing lists for campaigns.
Properly formatted email lists reduce import errors, improve deliverability, and ensure your email platform processes every address correctly. Use this tool before every list import to catch formatting issues before they cause problems.

- Paste your raw email list into the text box above.

Frequently Asked Questions
What formatting issues does this tool fix?
It removes extra whitespace, fixes multiple consecutive dots or @ symbols, strips leading/trailing spaces from each address, and validates the final format. Addresses that cannot be fixed are removed from the output.
Will it remove duplicate emails?
The formatter validates and cleans each address but does not deduplicate by default. Use the Email Splitter tool if you need deduplication alongside formatting.
What separators are supported in the input?
You can separate input emails with commas, semicolons, or new lines. The tool handles mixed separators automatically.
