Email signatures for Microsoft 365

Read-only on your directory, write access to one thing. Signivo reads users, groups and org units so it can fill in names, titles and departments, and it cannot change anything there. The only thing it writes is the signature setting of each mailbox. You see the full list of permissions in the Google Admin console before you approve it, and you can withdraw it any time.

No. Signivo does not read your mail. It touches the signature setting of each account, which is where a signature lives, and nothing else. No message is ever opened, stored, searched or forwarded.

Not by your team. No add-in, no browser extension, nothing to roll out. One admin connects Signivo in the Google Admin console, and signatures are written from there. Anyone using a mail client other than Gmail can set theirs up from a link, but that is the exception.

Only a Super Admin can approve access to your directory in Google Workspace. The Super Admin does it once, and never touches it again.

You design the signature once in Signivo and choose who should get it. Signivo automatically fills in each person's name, job title and contact details from your Google Workspace directory, then writes the finished signature into their individual Gmail account. Before anything is written you as an admin get a list of exactly which mailboxes are affected, and nothing happens until you approve it.

Yes, in the Gmail app on iPhone and Android. Since 2025 the Gmail app uses the web signature, images and formatting included, unless someone has set their own signature on their phone. Signivo writes the web signature, so it carries across.

Within the hour. Signivo checks your Google Workspace directory hourly and updates the affected signatures as soon as something changes, a new job title for example. You can also trigger a sync yourself instead of waiting.

You create different groups in Signivo. Point a signature at everyone, at one department such as Sales, at a Google group, at named colleagues or at a shared mailbox, and give each its own signature. Each signature has one target, and you can exclude individual people from it. If two signatures cover the same person, the higher priority one wins, so nobody ends up with two signatures. When a colleague moves to another team, they pick up that team's signature on the next sync.
