An HTML signature can present your business details clearly, but it should still be useful when a logo does not load or formatting changes. Treat the signature as contact information first, with branding supporting that task.
Keep essential details as readable text
Include the person’s name, role where useful, business name and the contact details recipients actually need. Avoid putting every detail inside one large image. If that image is unavailable, the recipient should still be able to identify and contact you.
A plain-text signature is a practical option for simple correspondence. A restrained HTML version can add a logo and clickable links. Choose the format that supports your staff’s correspondence and test it in their actual applications.
Allow for blocked images
Classic Outlook blocks automatic downloads of Internet pictures by default. Microsoft explains that this can help protect privacy and avoid tracking pixels. A missing linked logo is therefore not proof that the recipient’s application is faulty. See Microsoft’s picture-download guidance.
Use a small, appropriately sized logo with meaningful alternative text. Keep the person’s name and contact details outside the image. Do not ask recipients to weaken their general privacy settings merely to view your branding.
A checklist before rolling a signature out
- Details: confirm the spelling, role, telephone number, address and website.
- Links: send a real test message and check the email, telephone, website and social links that are included.
- Images off: verify that the sender and contact details remain understandable without the logo.
- Screen size: check a narrow phone view and ensure long details do not force awkward horizontal scrolling.
- Appearance: inspect text contrast and spacing in the light and dark display modes staff and recipients use.
- Conversation: check a reply and forward, where indentation and repeated signatures can make a layout cumbersome.
- Consistency: confirm the correct signature is attached to each sending account and any shared-address workflow.
Record which applications and versions were tested and any differences you accept. A desktop preview alone does not demonstrate that all recipients will see the same result. This checklist describes recommended checks, rather than a claim that a particular signature has passed them.
Keep the signature current
Assign responsibility for staff changes, contact updates and replaced logos. Retest links after a website or domain change. Remove abandoned promotions and icons that no longer help the recipient.
