Your email signature,
your best marketing channel.

Yes, EmailSign is completely free to use. Create your email signature, customise it and copy the HTML without creating an account. A Pro plan with advanced analytics and additional features is coming soon.

Yes. Our HTML uses table-based layout with inline styles — the gold standard for email compatibility. It works with Gmail, Outlook (desktop and web), Apple Mail, and Infomaniak kMail.

Not at all. Fill in the form, customise the style visually, and copy the generated HTML. Our installation guides walk you through the process in your email client step by step.

Yes. Simply paste the public URL of your logo (hosted on your website or a service like Imgur). The same applies to your profile photo and promotional banner.

Link analytics let you track how many times the links in your signature are clicked (website, social networks, etc.). This feature is available in the Pro plan and helps you understand who engages with your emails.

Go to Gmail Settings → General → Signature. Create a new signature and paste using Ctrl+Shift+V (preserves formatting). Our detailed installation guide covers Gmail, Outlook, Apple Mail, and Infomaniak.

We recommend a maximum width of 600px and a height of 150–200px for a clean, professional look. For any images (logo, photo, banner), keep file sizes under 50KB to ensure fast loading and avoid spam filters.

Outlook uses its own rendering engine based on Microsoft Word, which has limited CSS support compared to Gmail. EmailSign generates table-based HTML with inline styles specifically optimised for Outlook compatibility, reducing rendering differences.

Yes — simply paste your Calendly or booking page URL into the Website field, or use it as the destination for your main call-to-action link in the signature builder.

No. All your signature data is stored locally in your browser using localStorage. Nothing is sent to our servers unless you choose to create an account.

Enable the "Legal disclaimer" toggle in the Extras section of the builder. A default GDPR-compliant confidentiality notice is pre-filled — you can edit it to match your company's specific legal requirements.

Host your logo image publicly (on your website, Imgur, or a similar service), then paste the public image URL into the Logo URL field in the Branding section. We recommend PNG or SVG format at 200–300px wide for best results.
