What should a professional email signature include?
A strong signature has your full name, job title, company name, a primary contact method such as a direct phone number, and a clickable link to your website or LinkedIn profile. Optional additions include a small logo, social icons, your pronouns, a booking link and a brief legal disclaimer if your industry requires one. Keep the total to four or five short lines. Anything more competes with the message body and looks cluttered on mobile screens.
Why does the generator produce HTML instead of plain text?
HTML signatures support styled fonts, brand colors, clickable links, inline logos and proper spacing, none of which work in plain text. The generator outputs table-based HTML with inline CSS, which is the format email clients like Outlook and Gmail render most reliably. Tables and inline styles survive forwarding and quoting better than modern flexbox layouts. You can paste the generated HTML directly into your client's signature settings.
How do I install the signature in Gmail or Outlook?
In Gmail, open Settings, scroll to Signature, click Create new, and paste the rendered preview directly into the editor. In Outlook desktop, go to File, Options, Mail, Signatures, click New, and paste the preview. For Outlook on the web, use Settings, Mail, Compose and reply, then paste into the signature box. Always paste the rendered preview rather than the raw HTML code, otherwise the markup will appear as text instead of formatted output.
Will my signature display correctly on mobile devices?
The generator builds responsive, table-based layouts that scale down gracefully on phones. Logos are sized to remain crisp on retina displays, and font sizes stay readable on small screens. Avoid stacking too many social icons or a large banner, since mobile clients often stretch them awkwardly. Always send a test message to your own phone and view it in both Gmail and Apple Mail before rolling out the signature across your team.
Should I include images or a logo in my signature?
A small logo improves brand recognition, but use it carefully. Host the image on a public CDN or your own server and reference it by HTTPS URL rather than embedding it as a large attachment, which would inflate every message and trigger spam scores. Keep the logo under 300 pixels wide and 40 to 80 kilobytes in file size. Include descriptive alt text so the signature still makes sense when recipients have images turned off by default.
Can a poorly designed signature hurt my deliverability?
Yes. Heavy images, long disclaimers, multiple tracking pixels and excessive links all raise spam scores, especially on cold outbound messages. Some signatures are larger than the email itself, which filters treat as suspicious. Keep total weight under 100 kilobytes, host images externally, limit links to two or three, and avoid repeating the same disclaimer on every reply. A clean, lightweight signature lands in the inbox while a heavy one risks the promotions tab or junk folder.
