Memo is the email design studio for agencies and marketing teams - design once, send anywhere. These free tools solve the urgent QA and preparation steps that happen before every send, using the same practical standards we build into Memo Check and the editor.
FAQ
- Do I need a Memo.ly account?
- No. Every tool runs in your browser without signup. Import into Memo.ly only when you want to edit or send from the design studio.
- Is my email content stored on your servers?
- No. Tool processing happens locally in your browser unless you explicitly import into Memo.ly.
- Are these spam score or deliverability tools?
- No. They provide practical previews, checklists, and guidance - not inbox placement guarantees or spam scoring.
