A: Thanks for asking!
To ensure that all email signatures created with Newoldstamp are fully responsive and compatible across different email clients and devices, we don’t support uploading custom or ready-made signature designs.
Every email platform (like Gmail, Outlook, Apple Mail, etc.) has its own formatting quirks, so our Editor is built to generate code that adapts reliably across all of them. By using the Editor, you can be confident that your signature will always look professional, no matter where it's viewed.
If you need any assistance with reproducing the design, please feel free to contact us at support@newoldstamp.com, and we will do our best to help.
