How to create Gmail signature: Step-by-step guide
A Gmail signature is more than just your name at the bottom of an email — it’s a digital business card that conveys professionalism, credibility, and essential contact details. Whether you’re a student reaching out to professors, a freelancer pitching clients, or a corporate professional managing daily correspondence, a signature helps recipients quickly identify who you are and how to reach you. It can include your job title, company name, phone number, website, or even social media links. Gmail also allows customisation with fonts, colours, images, and logos, making it easy to align your signature with your personal brand or company identity. In this guide, we’ll walk you through the simple steps to create, edit, and manage your Gmail signature so that every email you send looks polished and professional.
