Signature guide
How to manage email signatures for a company
Every email your team sends is a small landing page. Multiply that by fifty people and a hundred messages a day, and the signature becomes the single most-viewed piece of design your company owns. Here's how to actually manage it — the four common approaches, what each costs in time, and where they break as you grow.

Step-by-step
- 1
Agree the signature is a marketing surface, not IT plumbing
The first mistake is treating signatures as an IT task. They're a brand surface: logo, tagline, colors, the campaign banner running this month. Owner is marketing (or the founder); IT's job is to make it easy to install, not to design it. Get this straight before you pick a tool. - 2
Pick one of the four approaches
1. Word doc in a Slack channel. Someone pastes HTML into #general and hopes everyone updates. Reality: half the team never does. 2. IT signature server (Exclaimer, CodeTwo). Server-side injection at send time — great for 1,000+ mailboxes with a real IT team, overkill for 20. 3. Per-person signature app (WiseStamp, Newoldstamp). Everyone builds their own; hard to keep on-brand. 4. Team signature platform (Wren). Central design, per-person install link, banner swaps live for everyone. For 5–100 people, this is usually the right shape. - 3
Design one signature, not fifty
Pick one layout for the whole company. Same logo position, same font, same social icons, same divider style. What changes per person is name, title, photo, phone — that's it. This is the single biggest win: five minutes of design decisions save a hundred one-off "can you fix mine" messages later. - 4
Roll it out with a personal link, not an HTML file
Sending a raw HTML file over email breaks in transit and every teammate needs to hand-edit their name. Instead give each person a pre-filled install link — they open it, see their signature already personalised, click Copy, paste into Gmail once. Wren generates one per teammate; if you're rolling your own, at minimum use a shared Google Doc with a per-row copy button. - 5
Make the banner the changeable part
A rebrand, a launch, a fundraiser, a Black Friday sale — you shouldn't need to re-install a signature for any of these. The banner beneath the signature is where campaigns live. Point it at a hosted image (a public URL) rather than embedding the file, and you can swap it across every teammate's signature in one place without touching a single mailbox. - 6
Audit quarterly, not never
People change titles, get promoted, leave. Once a quarter, ask everyone to send you a screenshot of a real sent email — not the settings screen, an actual reply. Five minutes catches every broken avatar, dead LinkedIn link, and "Junior" that should say "Senior". If you're on a team platform, this is a table view; if you're on Word-docs-in-Slack, it's a manual reminder.
Common questions
›Do we need Google Workspace admin access to roll signatures out?
No — only if you want server-side injection (the Exclaimer approach). Per-person install works on any Gmail, Outlook, or Apple Mail account without admin rights: each teammate pastes once into their own settings. This is what makes 5–100 person teams move fast without an IT ticket.
›What about people who forget to install it?
Team platforms show you an install dashboard: who copied their signature, who didn't. A single nudge in Slack usually closes the last 20%. Without that, you're relying on trust — which works for the first ten hires and breaks somewhere around fifteen.
›Can we run different banners for different departments?
Yes — but honestly, most teams get more mileage from one great banner everyone runs than five average ones per team. Segmented campaigns are a real feature (Wren supports it), but start company-wide and only split if the numbers say to.
›How much time does this actually save?
A team of 20 spends roughly 3–4 hours per rebrand or campaign update just on signatures — email chains, wrong versions, Slack screenshots. A central platform makes it a five-minute change, once. Over a year with four campaigns, that's a working day back.
