In this guide
A QR code helps a recipient open your contact page on another device or from a printed email. A clickable link is usually easier when they read on the same phone. Use a readable signature with your contact details as text, then test how it looks when received in the email apps your audience uses.
Decide whether a QR helps the recipient
A signature should answer who you are and how to reach you. If someone reads your email on a phone, scanning an image on that same screen adds friction. Keep the destination available as an ordinary link.
The QR is still useful when an email is read on a computer and the recipient wants your contact on their phone, or when a message is printed. It should complement the link, not replace the basic information.
Keep the destination focused
A published digital business card makes a good destination: it offers contact saving and a concise identity. A relevant portfolio or company profile also works when it fits the conversation.
Use a stable public address and check it without being logged in. With a dynamic QR, keep the account and domain behind it maintained; a signature doesn’t become reliable just because its image is saved in a template.
Design for the received email, including blocked images
Include your name, role and a text link so the signature still works when images are hidden. Don’t make a logo, banner or QR the only source of identity or contact details. Email apps render spacing and images differently.
Keep the layout restrained and send a test to another account. Look at the received email on a phone and a computer, not just the editor preview. Check replies as well: a large signature repeated in every message clutters a thread.
Install in Gmail or Outlook using their own settings
In Gmail on a computer, signatures are in the full settings under the General tab. Add the signature, choose the defaults for new emails and replies, and save. Google’s help explains multiple signatures and send-as addresses.
For Outlook on the web and the new Outlook, Microsoft documents signatures under Settings › Accounts › Signatures. Options depend on the version and account, so follow the official instructions for your edition; classic desktop Outlook works differently.
Use click reports without overstating them
QRflick builds signatures from your digital card and, on the paid plans, adds a promotional banner and click reporting for the signature’s links. Those reports describe link activity; they don’t tell you how many people read each message or whether a sale followed.
Questions, answered
Is a QR better than a clickable link?
Not for everyone. A link is convenient on the same device; a QR helps across devices or in print. Offer both when it makes sense.
Will my signature look the same in every email app?
No. Test received messages in the apps that matter, especially with images blocked.
Do signature clicks equal emails opened?
No. A click on a link and an opened message are different events. Read each report for the action it measures.
