How Email Signature Rescue Keeps Your Emails Private

When choosing an email signature service, privacy might not be the first thing on your mind, but it should be. Many email signature providers inject HTML "in-flight," meaning they access and modify your emails as they are sent.

How Email Signature Rescue Keeps Your Emails Private

While this ensures that email signatures appear on all devices, including mobile, you have to weigh the trade-off: you’re also giving that company access to your email server. This means they can read, modify, and even sell data from your emails. At Email Signature Rescue, we do things differently. We believe your emails should stay private.

No “In-Flight” HTML Injection

Unlike competitors who modify emails mid-send, we only inject HTML directly into your email compose window. This means we never need access to your email server, and we never see, store, or process your emails.

At Email Signature Rescue, we’re committed to giving you a professional email signature without compromising your privacy. Because your emails should stay yours.

No Email Server Access = Total Privacy

Some signature services require permission to monitor and modify your outgoing emails on the server level. This means they can read, analyze, and potentially sell data from your messages. We find this unacceptable. With Email Signature Rescue, your email content remains yours, untouched, unread, and completely private.

How We Support All Devices – Without Compromising Privacy

We understand that a consistent email signature across all devices is important. That’s why we offer:

✔️ Automatic Installation with a Signature Key – Most of our supported email clients use a Signature Key, where users simply paste a unique key into an app or extension. Our software then:

  • Auto-injects the HTML signature directly into the compose window when using a browser.
  • Installs the signature into supported email clients on Windows and MacOS.

✔️ Manual Installation for Mobile Devices – For mobile users, we still offer full support, but installation requires a one-time manual setup to keep your emails completely private.

Your Email, Your Business

When you send an email, it should be just that, your communication with your recipient. No hidden data collection. No middlemen modifying your message. No privacy risks.
