Wren vs. Exclaimer — an honest comparison.
Exclaimer is a category-defining email-signature platform, especially strong for enterprises running Microsoft 365 or Google Workspace at scale. If you have IT leading a signature rollout to thousands of mailboxes with directory-synced rules and server-side enforcement, Exclaimer is a serious choice. Wren is built for a different shape of team: five to a hundred people who want a flat price, twenty well-designed templates, and a banner they can swap for the whole company from a browser tab — with no IT project.

The eight things most teams ask first.
Where each tool actually wins.
Marked plainly. If Exclaimer is the right answer for a row, we say so.
Enterprises of 500+ mailboxes on Microsoft 365 with a dedicated IT team, an Entra directory as the source of truth, and a mandate for server-side signature enforcement across every send path — including Outlook mobile and delegated mailboxes — should pick Exclaimer. If your compliance team requires SOC 2 Type II or ISO 27001 today, Exclaimer clears that bar and Wren does not. We'd rather tell you plainly than have you find out three months in.
- • You're 5–100 people and want one flat price for the whole company.
- • You don't have (or don't want to spend) an IT project on signatures.
- • You want the banner under every signature to be a real marketing channel — swapped in a click.
- • You'd rather pick from forty designer templates than configure a template from scratch.
- • You need server-side signature enforcement across thousands of mailboxes.
- • Signature routing has to reflect complex directory attributes (department, role, region).
- • You already have IT leading a Microsoft 365 or Google Workspace deployment.
- • Enterprise SLAs, SSO, and centralised admin controls are must-haves.
What a 30-person team actually pays.
Exclaimer doesn't publish flat prices on its pricing page — most tiers are quoted via sales — so we won't invent a number. Here's the honest side-by-side for a 30-person team as of July 2026:
Team plan covers up to 50 people. No per-seat charge, no annual commitment required.
Per-user pricing set by Exclaimer sales; total scales with mailbox count and modules. Confirm current numbers on exclaimer.com.
If the quoted per-user number lands anywhere in the typical enterprise-signature range, a 30-person team on Wren is dramatically less at flat $99/mo — but pick the tool that fits the problem, not just the price.
One click. Every teammate's next email carries the new banner.
Real Wren campaign banner — rendered once, hosted by Wren, shown under every signature until you swap it.
Migration mini-guide.
- 1Recreate the design in Wren's studio
Open the free studio, pick one of forty templates, drop in your logo and brand colour. Everything is live-previewed against Gmail, Outlook and Apple Mail.
- 2Send one invite link
Add teammates by name and email. Each person gets a personal install link — no admin console for them to log into.
- 3Each teammate pastes once
They open the link, click Copy, and paste the signature into their mail client's signature settings. About 30 seconds per person. This is the honest trade — teammates paste once themselves, and that's the cost of a tool that never touches your mail server.
- 4Point the banner space at your first campaign
Pick a designed banner or upload your own. The image swaps under every teammate's signature on their next email — no re-install.
- 5Cancel Exclaimer at renewal
Your Wren signatures keep working because they live in each mail client. Turn off Exclaimer once you're happy — no lock-in on our side either.
Questions we get asked.
+Is Wren a full replacement for Exclaimer?
For 5–100 person teams on Google Workspace or Microsoft 365, yes — Wren handles the designed signature, per-teammate install, and a swappable company-wide banner. For 500+ mailboxes with Entra/Okta directory sync, server-side signature enforcement across every send path, or Teams/Meet branding, Exclaimer is the better tool and we say so plainly.
+What do I actually lose by switching from Exclaimer to Wren?
Three things. Server-side injection: teammates paste their signature into Gmail/Outlook/Apple Mail once instead of it being applied automatically at send time. Directory sync: no automatic pull of names and titles from Entra/Google/Okta — the owner (or each teammate) types their details once. Enterprise certifications: Exclaimer holds SOC 2 and ISO 27001; Wren does not.
+Does Wren access our mailboxes?
No. Wren never connects to Gmail, Outlook or any mail server. The signature is HTML that lives in each teammate's own client. The banner image is served from Wren over HTTPS and updates everywhere when you swap the campaign — no re-install, no mailbox access.
+What happens to signatures if we cancel Wren?
The signature HTML keeps rendering exactly as it is, because it lives in each mail client. The hosted banner image stops serving on cancellation and the banner space becomes empty in future emails; already-sent emails aren't affected.
+Can we try Wren free?
Yes. Free forever for 1 person, 1 live banner, and the full 20-template studio — no card, no time limit. The Team plan is a flat $99/mo up to 50 people; Scale is $199/mo up to 100.
+How long does switching from Exclaimer take?
For a 30-person team, an afternoon. Recreate the signature in Wren's studio, send one invite link, each teammate pastes it into their mail client once, point the banner space at your first campaign, then cancel the old tool at renewal.
Design a signature in the free studio, copy the HTML, paste it into Gmail or Outlook. No signup, no card.
