Your email signature is the business card you hand out dozens of times a day without thinking about it. Reusing your actual card design there keeps your branding identical everywhere a contact meets you — on paper, on screen and in their inbox.
Prepare the image first
Export your card as a high-resolution image, then keep the displayed size modest: around 300–400 pixels wide is the sweet spot where the card is readable without dominating the email. Two warnings from painful experience: huge images get clipped or flagged by mail clients, and a signature image should never be the only place your phone number exists — always keep a plain-text name and number line for recipients whose clients block images.
Adding it to your mail client
Apple Mail on Mac: Settings → Signatures, create a signature and paste the image directly in. Gmail: Settings → See all settings → Signature, insert the image from Drive or upload. Outlook: Settings → Signatures, insert picture. Mail on iPhone and iPad only supports text signatures natively — on iOS, put your card image in Photos and attach it when it matters, or rely on your other clients for the visual version.
How to do it in AI Business Cards Generator
- Open your finished card design — or create one from a template with your details, logo and colors.
- Consider a signature-friendly variant: the front side with name, role and one contact line reads best at small sizes.
- Export the high-resolution design and save it to Photos or Files.
- Send it to the device where you manage email, resize if needed, and insert it into your signature using the steps above.
- Email yourself once and check it on a phone screen before rolling it out.
If you want the signature to be actionable, add a QR code or link — the logic is the same as in sharing a business card digitally from iPhone and making a QR code that shares your contact details.
