Works with the tools your team already uses
Three steps, no IT project.
Upload a CSV with names and emails. Re-upload a corrected file any time — rows match on email and update in place.
Choose from curated, email-safe designs and see them rendered with your own details before anyone gets one.
Everyone gets a link to their personal signature with step-by-step install instructions for their mail client.
Import people from a CSV, or sync them from Google Workspace or Microsoft Entra ID. Each signature is filled in from that person's row, so nobody has to type their own.
Start with copy and paste: nothing to install. Connect Google Workspace or Microsoft 365 when you want every mailbox kept up to date.
Schedule a banner for everyone or chosen departments, A/B test two banners, and see which links get clicked. signplume never records who clicked.
Connect Claude, ChatGPT, Microsoft Copilot or another assistant, and set up people, designs and campaigns by asking.
Pick an on-brand template and everyone gets a consistent signature — no copy-pasting fonts and logos person by person.
Connect Google Workspace and signplume pushes each signature straight into Gmail. On Microsoft 365, the Outlook add-in inserts it as people write.
Import people from a CSV, or sync them from Google Workspace or Microsoft Entra ID; each signature is filled in with that person's name, title, phone and department automatically.
Table-based, inline-styled HTML with images hosted over HTTPS — it survives Gmail's image proxy and pastes cleanly into Gmail, Outlook and Apple Mail.

If you turn on server-side signing, your mail transits our relay only to be stamped and handed straight back to your own platform for delivery. A message is deleted the moment the hand-back succeeds, and a message we cannot deliver is kept only through the retry window, then deleted. We keep no copy of delivered mail and nothing for analytics. The add-in and copy-paste options never route your mail through us at all.
No. Each person opens their own page and copies their signature into Gmail, Outlook or Apple Mail — we ship click-by-click instructions for each one.
Re-upload your CSV and new people appear ready to invite. Archiving someone frees their seat immediately and keeps their history.
Templates are table-based with inline styles — the subset Gmail, Outlook and Apple Mail render. Images are served over HTTPS so Gmail's proxy can fetch them.
Yes. Set one organisation default and override it per department, so Sales and Engineering can differ without maintaining two templates by hand.
