Frequently Asked Questions
How to add an HTML email signature in Gmail? ▼
Go to Gmail → Settings (gear icon) → See all settings → General tab → Signature → Create new. In the signature editor, click the "Source" or "" button (if available) and paste the HTML code. If no source editor, use the "Insert HTML" approach via Google Admin. Alternatively, create the signature in a browser, copy the formatted version and paste directly into Gmail's editor.
How to add an HTML email signature in Outlook? ▼
In Outlook: File → Options → Mail → Signatures → New. Create a plain signature first, then for HTML: go to %APPDATA%\Microsoft\Signatures, open the .htm file in Notepad and replace with your HTML code. In the web version (Outlook.com): Settings → View all Outlook settings → Compose and reply → Email signature.
What size should an email signature image or logo be? ▼
Keep logos under 100×50 pixels for email signatures — larger images are often blocked by email clients. Use PNG format for transparency. Host the image on a public URL rather than embedding it (embedded images may be blocked). Total signature size should be under 80KB for fast loading.
Does an email signature affect email deliverability? ▼
Excessive HTML in signatures can trigger spam filters. Best practices: avoid too many images, do not include multiple URLs, avoid ALL CAPS, keep the HTML clean and lightweight. Our generator creates clean, minimal HTML that is spam-filter-friendly.
What should not be in a professional email signature? ▼
Avoid: motivational quotes (unless brand-relevant), animated GIFs, too many social icons (pick 2–3), legal disclaimers longer than 2 lines, bright background colors, multiple font colors and very large text. Keep it clean: name, title, company, phone, website and 2 social links is the ideal compact format.
