What to put in an email signature

Your name, job title and company, plus one or two ways to reach you, usually a phone number and a website. A photo or logo and a few social links help people recognise you. Keep it to four or five lines so it reads well on a phone.

Name and job title, so people know who wrote to them.
Company name and website, so they can look you up.
A phone number, if you take calls.
A photo or logo hosted on a public https:// link.
Two or three social links you keep up to date.

Questions about email signatures

Will my photo and icons show up for the people I email?

Yes, in most mail apps, as long as the photo or logo link is public and starts with https://. The image loads from that link each time someone opens your email, so leave the file where it is. Some mail apps hide images until the reader allows them. Your name and details are text, so they always show.

Why does my round photo look square in Outlook?

Classic Outlook for Windows ignores rounded corners, so round and rounded photos show as squares there. Gmail, Apple Mail and Outlook on the web keep the shape you picked. If the square bothers you, pick Classic Forest or Centered Coral, which use a square photo on purpose.

Is this email signature generator free?

Yes. You can make and copy as many signatures as you like, with no account. Each free signature ends with a small “Created with Sidekitly” link.

Does what I type leave my browser?

No. The signature is built on your device and your details are not sent to Sidekitly. Your photo and logo load from the links you paste, the same way they will for the people you email. When you copy, the page counts that a signature was copied, without any of its content.

What is the “Created with Sidekitly” line?

A small grey link at the bottom of every free signature that points to this page. It lets people who get your emails find the tool, which is how we keep it free without ads.

Which mail apps does the signature work in?

Gmail, Outlook (web, Windows and Mac), Apple Mail on Mac, Yahoo Mail and Thunderbird. Apple Mail on iPhone takes mostly the text, so the photo and icons may not come through there. The signature is built from tables and inline styles, the kind of HTML mail apps display most reliably. The steps for each app are in the guide above.
