I totally agree. Almost all other mail providers have an option to set up another signature for replies/forwarding. This should be a standard feature. Please add it

Also chiming in to request this feature! I have a long signature that makes email threads annoying and hard to follow unless I manually delete, and it's a pretty standard feature on other platforms.

Dear Proton Mail Team,

I am writing to express my concern about a missing feature in Proton Mail that I consider essential for professional email use: the ability to include an email signature only in new messages, while automatically omitting it in replies and forwards.

This is standard functionality in virtually every major email client — including Outlook, Thunderbird, and Gmail — and its absence in Proton Mail forces users to manually delete their signature on every reply, which is both inefficient and easy to forget.

A signature in a reply thread serves little purpose and adds unnecessary clutter, especially in ongoing conversations. The ability to control this behavior per message type (new compose vs. reply/forward) is not a luxury — it is a basic expectation of a professional email service.

What makes this particularly hard to understand is that the signature feature itself already exists and works well. Implementing a simple toggle to disable it for replies and forwards should not require significant development effort — it is essentially adding an on/off switch to functionality that is already in place.

I understand this has been requested by other users on your feedback platform and I would like to add my voice to that request. I strongly encourage the Proton Mail team to prioritize this feature in an upcoming release.

Thank you for your attention to this matter.

Kind regards,
Richard

How on earth is this not a standard feature?!
