How to add an email signature in Proton Mail
Setting up a professional email signature in Proton Mail takes just a few minutes with Signaturely. Build your signature with our free generator — add your logo, social icons, contact details, and brand colors — then copy the ready-made HTML and paste it into Proton Mail’s signature settings. The result renders correctly in Browser, iOS and stays consistent across every message your team sends.
Because Proton Mail handles HTML signatures natively, you don’t need any plugins or technical setup. Everything is embedded in a single block of table-based HTML that survives forwarding, replies, and dark-mode rendering.
Step 1 — Generate
Use the Signaturely generator to design your signature: name, role, logo, social icons, and banner. Live-preview as you type.
Step 2 — Copy HTML
Export or copy the generated HTML with one click. The markup is table-based and email-client safe, ready for Proton Mail.
Step 3 — Paste & send
Paste it into Proton Mail’s signature settings, save, and send yourself a test email to confirm spacing and images.
