Question 1

Accepted Answer

To add your email signature in Gmail: (1) Click "Copy to Clipboard" above to copy your signature. (2) Open Gmail and click the gear icon, then "See all settings." (3) Scroll down to the "Signature" section. (4) Click "Create new" to add a signature name. (5) Click inside the editor and paste your signature with Ctrl+V (or Cmd+V on Mac). (6) Scroll to the bottom and click "Save Changes." Your signature will now appear automatically on new emails and replies.

Question 2

What should I include in a professional email signature?

Accepted Answer

A professional email signature should include your full name, job title, and company name at minimum. Beyond that, add your email address, phone number, and company website. Social media links (LinkedIn especially) are valuable for networking. Keep it concise — 3-5 lines of contact info is ideal. Avoid inspirational quotes, excessive colors, or large images, which can look unprofessional and cause formatting issues across different email clients.

Question 3

How do I add an image or logo to my email signature?

Accepted Answer

Our signature generator supports profile photos and company logos via URL. To use an image: (1) Upload your photo or logo to a permanent hosting service (like your company website, Imgur, or Google Drive with public sharing). (2) Copy the direct image URL. (3) Paste it into the "Profile Image URL" or "Company Logo URL" field in our generator. The image will be embedded in your signature HTML. Important: use a hosted URL, not a local file path, so the image displays for all recipients.

Question 4

Why is my email signature not formatting correctly?

Accepted Answer

Email signature formatting issues usually stem from a few common causes: (1) The email client modified the HTML when pasting — try using "Copy to Clipboard" (rich text) rather than "Copy HTML Code." (2) The receiving email client doesn't support certain HTML/CSS features — our templates use table-based layouts specifically for maximum compatibility. (3) The image URLs are broken or inaccessible. If issues persist, try the Compact template which has the simplest formatting and works everywhere.

Question 5

Can I have different signatures for different email accounts?

Accepted Answer

Yes, most email clients support multiple signatures. In Gmail, you can create several signatures and assign different ones to different email aliases or accounts. In Outlook, go to Signature settings to create and manage multiple signatures. You can even set different default signatures for new messages versus replies. Use our generator to create different versions — for example, a detailed Professional signature for clients and a Compact one for internal emails.

Question 6

What size should my email signature be?

Accepted Answer

Keep your email signature under 650 pixels wide (the standard email width) and under 150 pixels tall for optimal display. Profile images should be 60-80 pixels in diameter, and company logos should be under 200 pixels wide and 50 pixels tall. Total file size of all images should stay under 50KB for fast loading. Our templates are designed within these guidelines to ensure your signature looks great and loads quickly across all email clients.

Question 7

Do email signatures work on mobile devices?

Accepted Answer

Yes, our email signatures are built with responsive, table-based HTML that works on both desktop and mobile email clients. Once you set up your signature in Gmail, Outlook, or Apple Mail, it will appear on emails sent from your phone automatically. However, note that some mobile email clients may slightly adjust the layout. Test by sending yourself a test email and viewing it on your phone before using it in production.
