Signatures can be added in different ways, depending on the signature mode in which the software operates: server-side, client-side or combo. Signature mode is first selected when you register your Office 365 tenant to our service but can be later changed at any time.

Data security and privacy

Data security & privacy

AdSigner does not use any email relay techniques to insert your signature or connect to your email provider in any way that would allow us to see your private correspondence. All collected analytical data is anonymised. The analytics feature may be disabled altogether on request.
The signature data you enter is used for the sole purpose of generating email signatures. Your signatures are only accessible through your account or accounts that you delegate access to. We never share your email signatures with third parties. Cyber security and data protection is our top priority. This is the main reason why we designed our software to be inserted client-side only to eliminate any security risks.

GDPR compliant

We are GDPR compliant. We take precautions to safeguard your personal information against loss, theft, and misuse, as well as against unauthorized access, disclosure, alteration, and destruction. As part of GDPR requirements Companies using AdSigner and handling European user data may need to sign a Data Processing Agreement (DPA). DPA is available to download.
