Why the logo must be an image web address

Your signature travels as HTML inside every email you send. When you paste an image file from your computer, Gmail and Outlook either drop it or attach it to every message, and many mail systems block images packed inside the HTML itself. An image hosted on your website loads like any web image. Upload a PNG or JPG to your site (or use the logo already on it: right-click it and choose "Copy image address"), check that the address starts with https:// and opens in a private browser window, and paste it here.

For businesses: the same signature for everyone, and the emails behind it

A consistent signature is the easy part. The bigger cost is the routine email itself: enquiries to answer, quotes to send, follow-ups to chase and replies to log in your CRM. AiStaffo sets up AI workers that draft and send these routine emails and follow-ups from your team's inboxes, and pass anything unusual to a person. Book a free automation audit to find out how much of your inbox could run itself.

Please note: the signature follows the HTML that Gmail, Outlook and Apple Mail display, as checked on 21 October 2026. Email programs change how they show HTML from time to time, so after saving it, send a test email to yourself and to someone using a different email program.
