Detailed Review
SignatureSatori is a signature management tool for Gmail. The site footer says it is a product of AppSatori s.r.o., and the contact page gives billing details at namesti Winstona Churchilla 1800/2, 130 00 Praha 3, Czechia. AppSatori is described there as a Google Cloud Premier Partner and Google Workspace Premier Partner.
It competes with WiseStamp for Gmail users, but works through a Google Workspace app rather than a Chrome extension.
Features
The vendor lists OAuth login, import of users and contact data from Google Directory, import of organisational units, a drag-and-drop visual editor, an HTML and CSS view, conditionally displayed content and daily set-up of signatures. It says it uses the Gmail API, so there is no change in email flow and no added point of failure.
Pricing models
Two models are offered. With credits, a one-time purchase, one credit sets or changes one signature for one user and then allows unlimited changes for 24 hours, with 5 free credits monthly. With the subscription, a monthly per-user payment, there are unlimited changes, a marketing planner and daily directory sync, with a minimum of 5 users. The amounts are set by a slider and were not in the page text.
Data
Signature images can be hosted by the customer or on Google Cloud Storage. The tool has a DPA and GDPR page, but the hosting region was not stated on the pages checked.
Limitations to Consider
Google Workspace only. Hosting region not stated. Server-side enforcement beyond daily re-set-up is not described.
