Email signatures, locked down.
Centrally manage every signature across Microsoft 365 and Google Workspace. Built by a cybersecurity company. Secure by design, privacy focused, set up in 5 minutes.
Three reasons to pick Stampify
We're not the cheapest signature tool. We're the one your security team won't make you rip out next quarter.
Secure by design
- Row-level permissions per tenant. Appwrite Teams scope every read.
- Encrypted-at-rest vendor refresh tokens.
- Minimum OAuth scopes. Never requests Mail.* or Files.*.
- Append-only audit log of admin actions.
Privacy focused
- We never read email content. The add-in only writes signatures.
- No tracking pixels or link rewriting in rendered signatures.
- No third-party scripts in the admin dashboard.
- Data residency. Pick EU or US at onboarding.
Ease of use
- 5-minute onboarding: connect, consent, pick template, done.
- Brand palette and templates are independent, so marketers tweak colors while designers ship layouts.
- Directory sync is hands-off. Users are added and suspended automatically.
- Self-serve user editing. No IT tickets for job-title changes.
Five-minute setup
From the M365 admin-consent screen to a live signature in Outlook, no professional services required.
- Step 1
Connect
Sign in as a Microsoft 365 or Google Workspace admin. Grant minimum-scope consent: read-only directory access, never mail.
- Step 2
Sync users
Stampify reads your directory and creates a signature row per user. Pick groups, exclude inboxes, or sync everyone.
- Step 3
Pick a template
Choose a default design, or build one with your colors and logo. Per-team templates if Marketing wants its own look.
- Step 4
Live in Outlook
Signatures appear on every new mail, reply, and forward, within the hour. No spreadsheet to maintain afterwards.
Design a signature, see it render
Edit the fields, pick a brand color, watch the signature update. No account needed. This is the same renderer that powers production signatures.

How Stampify compares
We're not the cheapest tool on this list, and we don't try to be the most feature-stuffed. We're the one that respects your tenant's permission boundary.

Comparison reflects publicly available information at the time of writing. We update this table when competitors ship changes that affect a row.
Secure because we built it that way, not because we bolted it on.
Stampify is produced by CyberITEX. Security and privacy aren't a checkbox here. They are the architecture.
- Tenant isolation
- Row-level permissions. Every query is scoped to one Appwrite Team.
- Minimum scopes
- User.Read.All + Directory.Read.All. No Mail, Files, or Calendar.
- Token storage
- Vendor refresh tokens encrypted at rest with a key outside the database.
- No content access
- The Outlook add-in only writes signatures. It never reads body, recipients, or threads.
- No trackers
- Zero third-party scripts in the admin dashboard. Click tracking is opt-in per template.
- Audit & deletion
- Append-only admin actions log. One-click tenant delete cascades to every related row.
