Exclaimer alternatives: where to go, and how to switch without breaking Outlook
Six destinations by reason for leaving, official prices for 50 mailboxes, and an eight-step cutover.
The short answer: Signitic if you want to pay less (free up to 19 employees, then €1 per user), CodeTwo if all your mail lives in Microsoft 365 and you want one plan with everything, Letsignit if marketing wants campaigns and A/B tests in the signature, Rocketseed for a 50 to 200 person company that thinks in banners, Opensense if you run account-based marketing through your CRM, and WiseStamp for a small marketing team on Google Workspace.
Before you pick, do the math honestly. For 50 mailboxes, Exclaimer costs $540 a year on Starter and $1,050 on Pro. If price is your reason, only Signitic and CodeTwo beat Exclaimer Standard, its first plan with campaigns (note that Signitic bills in euros, Exclaimer in dollars). If simplicity or Outlook is your reason, read the traps below first: some of them follow any server-side tool. We compared these six alternatives using their official pages in 2026.
The ranking is editorial: a sponsored placement is always labeled on its card, and no affiliate link changes a score.
Why teams leave Exclaimer, even though it rates well
Exclaimer is still a benchmark for server-side signatures: its pricing page offers server-side, client-side or both on every package, plus sync with Entra ID or Google Directory. That's why it scores 4.3 out of 5 in our email signature software ranking. People leave for other reasons: the plan they actually need, the learning curve, and three Outlook cases its own support team documents.
Starter isn't enough for a marketing team
Starter is $0.90 per user per month, billed yearly. It gives you one brand kit and one template, with no campaigns, and legal disclaimers but no disclaimer management (that comes with Standard). Campaigns start on Standard at $1.45. HR system, Salesforce and HubSpot integrations wait for Pro at $1.75. Going from Starter to Pro almost doubles the bill.
Every active mailbox is a license, with a 10-user floor
Exclaimer counts one license per email address that gets a signature applied, and the minimum is ten users. A six-person team pays for ten. Add shared mailboxes to the signature and the bill grows with them. Reviewers say the same thing from both ends: it's costly for small businesses, and costly again at thousands of users.
A steep learning curve
The most common complaint in reviews is the learning curve, especially around advanced rules and managing the image library. A competing vendor puts it bluntly: Exclaimer is built for IT pros managing complex org structures. If marketing owns your signatures, expect them to file a ticket with IT for every banner.
Classic Outlook: no signature in Sent Items
Exclaimer's support site says it plainly: with server-side signatures, classic Outlook in Cached Exchange Mode doesn't show the signature in Sent Items. Senders think the email went out bare. The vendor's recommended fix is to add client-side signatures too, which brings back per-device installs.
New Outlook: local client-side signatures vanish
In the new Outlook for Windows, locally stored client-side signatures don't show up, because Microsoft is moving to roaming signatures stored in the mailbox. Exclaimer's fix is its Outlook add-in. If your fleet is moving to new Outlook, budget for an add-in in any scenario, including with whichever competitor you choose.
Shared mailboxes: Send As isn't handled cleanly
When someone sends as another mailbox (sales@, support@), the sent item isn't updated with the signature. Exclaimer documents a Windows registry fix. It works, but it's a per-machine change. Add support that reviewers describe as uneven (quick for some, hard to reach for others), and you have the full picture.

Exclaimer alternatives, tool by tool
For each tool: why you'd move there from Exclaimer, who it suits, its limit, how to migrate, and what 50 mailboxes cost on its official price list. Scores for Signitic, CodeTwo, Letsignit and WiseStamp match our email signature software ranking, so a tool carries the same score everywhere on the site. Signature generators (MySignature, Newoldstamp, BulkSignature) show up in every roundup, but they are mostly signature builders for small teams: we left them out against Exclaimer because they lack a clear official price or documented central deployment. If you're leaving your mail platform too, see our guides to switching from Microsoft 365 or switching from Google Workspace.
Signitic: pay less, or nothing under 20 employees
CheapestWhy move to Signitic. If the bill is why you're leaving, this is the most direct answer. Signitic is free forever up to 19 employees, with one template and one campaign (plus a Signitic badge in the signature). Beyond that, Standard is €1 per user per month excluding VAT from 20 users. For 50 mailboxes that's €600 a year, against $870 for Exclaimer Standard, its first plan with campaigns.
Who it's for. Small and mid-size teams on Microsoft 365 or Google Workspace (both are covered on every plan) that want unlimited campaigns, A/B tests and scheduling without paying for a Pro tier. Nonprofits get 50% off.
Who it's not for. Companies that need targeting driven by the CRM or HR system: that sits on the Custom plan, priced on quote. And teams that want US-dollar invoicing, since Signitic bills in euros.
Its limit. The pricing page doesn't say whether signatures are applied server-side. If keeping signatures on mobile is the reason you chose Exclaimer, ask in the demo before you sign.
How to migrate from Exclaimer. Run your pilot on the free plan with a small group. It's the only tool here where the pilot costs nothing. Rebuild the template from a screenshot of your Exclaimer signature, connect the directory, then move to Standard when you add everyone else.

CodeTwo: one plan, built for Microsoft 365
Best for Microsoft 365Why move to CodeTwo. It's the alternative Microsoft admins mention most. On r/sysadmin, admins call it cheap and powerful, and one describes moving from Exclaimer to CodeTwo over a signature preview problem in Outlook. CodeTwo sells a single plan with every feature: $1.22 per user per month billed yearly for 10 to 25 licenses, $1.36 billed monthly (same amounts in dollars or euros), falling to $0.73 at 500 licenses.
Who it's for. IT teams on Microsoft 365 or Exchange who want Exclaimer's depth without choosing between three tiers. You get cloud server-side signatures with a preview, an Outlook add-in, a combined mode, and scheduled campaigns.
Who it's not for. Teams on Google Workspace: CodeTwo's offer is built for Microsoft 365 and Exchange. And teams under ten, with the same 10-license minimum as Exclaimer.
Its limit. Prices exclude tax and change by tier, so ask for the exact rate at your license count. For 25 mailboxes, budget $366 a year; for 50, at most $732 ($1.22 × 50 × 12), since the 26 to 50 tier isn't listed.

Letsignit: the signature as a marketing channel
Best for campaignsWhy move to Letsignit. If marketing finds Exclaimer too technical, Letsignit speaks their language. It covers Microsoft 365, Google Workspace and CRMs, with targeted campaigns, A/B testing, polls inside the signature and digital business cards (vCards). Its pricing page shows $2 per user per month for the Signatures & vCards, Slides and Platform offers, on an annual subscription.
Who it's for. Mid-size companies where marketing and IT share the signature: marketing runs campaigns, IT keeps control of the directory. For 50 mailboxes, the listed price works out to $1,200 a year.
Who it's not for. Small teams leaving Exclaimer to save money: Signitic is free up to 19 employees and CodeTwo starts at $1.22.
Its limit. It costs more than Exclaimer Pro per user, and Enterprise is priced on quote. Ask about any minimum billing before you compare.
How to migrate from Exclaimer. Use the free trial on the Signatures offer to rebuild templates and group rules. List the Exclaimer campaigns that are still running and recreate them in Letsignit before cutover, so no banner ends mid-flight.

Rocketseed: the clearest pricing for 50 to 200 employees
Best for bannersWhy move to Rocketseed. Rocketseed sells company-size tiers instead of a per-plan rate you multiply. For 50 employees it's $705 a year or $73 a month. For 100, $1,320 a year. For 200, $2,445 a year. Above that, it's on quote. You can pay in USD, GBP or EUR. It covers Microsoft 365 and Google Workspace and leans into signature marketing.
Who it's for. Companies of 50 to 200 people that use the signature to push banners and want a fixed budget instead of counting mailboxes one by one.
Who it's not for. Any team under 50 employees: the first tier listed is 50 employees.
Its limit. A one-time setup fee applies, and the amount isn't published. Get it in writing before you compare with Exclaimer.
How to migrate from Exclaimer. The 14-day trial is open from 50 employees. Have banners ready in the right sizes before you start, so the pilot judges rendering instead of producing creative.

Opensense: signatures that serve account-based marketing
Best for ABMWhy move to Opensense. If you're leaving Exclaimer because it stops short on B2B marketing, Opensense plays a different game. It targets banners by account (ABM, marketing aimed at named accounts), runs A/B tests and plugs into your CRM. Three plans: Signature at $1, Pipeline at $3 and Complete at $5 per user per month.
Who it's for. Large B2B sales and marketing teams that want a prospect at a target account to see a different banner than an existing customer.
Who it's not for. An SMB that just wants clean signatures. Plans include a $500 per month minimum and a platform license: at 50 mailboxes, that's at least $6,000 a year, eleven times Exclaimer Starter.
Its limit. That minimum, again. The pricing page doesn't mention a trial, so expect a demo. GCC High accounts cost $2 more per user.
How to migrate from Exclaimer. Connect the CRM and define account segments first. The signature itself is quick to rebuild; the targeting takes the work, and it's what justifies the price.

WiseStamp: the easiest pick for a marketing team on Gmail
Easiest to set upWhy move to WiseStamp. If Exclaimer's complexity is the problem, WiseStamp is its opposite: a polished signature in minutes, no IT department needed. Google Workspace and Microsoft 365 are covered from Basic, at $19 a month plus $1 per employee, billed yearly. Campaigns come with Grow at $49 plus $1. For 50 employees, Basic works out to $828 a year.
Who it's for. SMBs on Google Workspace whose marketing team wants banners and stats without waiting on IT.
Who it's not for. Teams that picked Exclaimer for server-side signatures. Basic and Grow are client-side only. Server-side needs Platform ($189 a month plus $1 per employee, so $2,868 a year for 50) or Enterprise.
Its limit. No free plan. Our guide to leaving WiseStamp covers what gets awkward when you move on from it.
How to migrate from Exclaimer. Use the 14-day trial, no card needed. Remove the pilot group from Exclaimer's server-side rule before you switch WiseStamp on, or their emails go out with two signatures.

Leave Exclaimer in eight steps
Order matters more than the tool. The first two steps protect your budget, the next three your templates, the last three your email. One rule runs through all of it: never have two tools active on the same mailbox.
Find your renewal date
FirstExclaimer bills yearly or monthly: check which one you're on. Find the renewal date and any notice period in your contract or customer portal. The whole migration hangs on that date: the cutover has to be done before it, with slack for stragglers.
Tip: ask your account rep for the exit terms in writing before you start anything. That one email can save you a year you don't need.

- date and notice
- Blocker
- contract access
List everything Exclaimer does for you
Week 1Write it all down: templates, rules by group or department, disclaimers, live campaigns, reply signatures, shared mailboxes that get a signature. Screenshot every template and grab your logos and banners as original files.
Count licenses too. At Exclaimer, every active mailbox that gets a signature is one. That's the number to give other vendors for an accurate quote.
- Output
- a list and screenshots
- Count
- shared mailboxes
Pick server-side, client-side or both
Server-side, the signature is added in transit and follows people onto their phones, but senders don't see it while writing, and classic Outlook in cached mode won't show it in Sent Items. Client-side, it's visible, but it installs device by device, and the new Outlook needs an add-in.
If your fleet mixes classic and new Outlook, aim for a tool that combines both modes, the way Exclaimer did.
- Key question
- who emails from a phone?
- Check
- Outlook versions in use
Clean up Entra ID or Google Directory
Exclaimer filled signatures from Entra ID or Google Directory, and your next tool will too. Fix wrong titles, phone numbers and departments now: every directory error becomes a typo your clients see.
- Source
- Entra ID or Google Directory
- If rushed
- typos in signatures
Rebuild templates and test them
Week 2Rebuild each template in the new tool from your screenshots, mapping fields to the directory. Send test emails from classic Outlook, new Outlook, a phone and a shared mailbox, to Gmail and Outlook.
Check the four cases that gave Exclaimer trouble: Sent Items, new Outlook, Send As from another mailbox, and replies deep in a thread.

Pilot with a small group
Turn the new signature on for three to five people on different devices, and take them out of Exclaimer's rules at the same time. Everyone else stays on Exclaimer until cutover.
Have them send real email for a few days. You'll catch duplicates and broken images before a client does.
- Group
- 3 to 5 people
- Rule
- one tool per mailbox
Remove Exclaimer cleanly
This is the step that causes double signatures when rushed. Server-side, Exclaimer runs through a connector and a mail flow rule in Exchange Online: they have to go, or every email keeps getting the old signature on top of the new one. Client-side, remove the Outlook add-in and the local signatures it set.
Do it department by department, at the pace you switch on the new signature, never all at once.
- Remove
- connector, mail flow rule, add-in
- If rushed
- two signatures per email
Move everyone, then cancel
DoneOnce the last department is across and tests have been clean for a week, cancel Exclaimer before the renewal date. Keep your screenshots and image files: they're your only record of the old template if a detail goes missing.

What makes an Exclaimer exit fail
None of these traps is about the new tool. They're oversights, and each one costs you either a year of subscription or badly signed emails in front of clients.
Comparing plan prices instead of plans
Exclaimer Starter at $0.90 has no campaigns, and its disclaimers can't be managed centrally. Always compare like for like: if you use campaigns, the benchmark is Standard at $1.45, not Starter.
Leaving the Exchange mail flow rule in place
Exclaimer's connector and rule in Exchange Online keep adding the old signature as long as they exist. It's the number one cause of double signatures after a server-side switch.
Assuming a competitor fixes Outlook on its own
Missing signatures in Sent Items and local signatures ignored by new Outlook come from how Outlook works. Every server-side tool runs into them: check the combined mode or add-in of your destination.
Forgetting shared mailboxes
Info@, support@ and billing@ send signed email too. Several vendors count them as licenses, and Send As needs its own test.
Ignoring minimums
10 licenses at Exclaimer and CodeTwo, 20 users on paid Signitic plans, a first tier of 50 employees at Rocketseed, $500 a month at Opensense. For a 15-person team, those floors reshuffle the whole ranking.
Switching everyone on the same day
A big-bang cutover multiplies duplicates and tickets. In waves, one department at a time, you fix a problem for five people instead of fifty.
Exclaimer alternatives: common questions
Is there a free alternative to Exclaimer?
Yes, for a small team: Signitic is free forever up to 19 employees, with one template, one campaign and a Signitic badge in the signature. Beyond that, paid plans start at €1 per user per month from 20 users.
What's the cheapest Exclaimer alternative?
For a small headcount, Signitic, thanks to its free plan. At 50 mailboxes, Exclaimer Starter ($540 a year) is still among the cheapest, but it has no campaigns. With comparable features, Signitic (€600) and CodeTwo, which drops to $0.73 at 500 licenses, come out ahead.
Which Exclaimer alternative works with Google Workspace?
Signitic, Letsignit, Rocketseed and WiseStamp all cover Google Workspace. CodeTwo is built for Microsoft 365 and Exchange. If you need server-side signatures on Gmail, ask for it explicitly: at WiseStamp, it takes the Platform plan.
Is CodeTwo better than Exclaimer?
For a Microsoft 365-only company, often yes: one plan with everything, pricing that falls with volume, and a monthly option at $1.36. For a mixed Google and Microsoft fleet, Exclaimer keeps the edge over CodeTwo because it covers both.
Does Exclaimer have a free trial?
Yes, 14 days, no card needed. Use the logic in reverse when leaving: open a competitor's trial, and meanwhile write down exactly what Exclaimer does for you. That list becomes your migration checklist.
Why doesn't my signature show in Sent Items?
Because a server-side signature is added after the email leaves. Classic Outlook in Cached Exchange Mode keeps the local copy, without the signature. The recipient still gets it. Exclaimer's recommended fix is to add client-side signatures as well.
How do I avoid double signatures during the switch?
One rule: one active tool per mailbox. Remove each person from Exclaimer's rules (and the Exchange connector at the end) when you switch on their new signature, and delete the local signatures the old add-in left behind.
How many licenses do I need at Exclaimer or a competitor?
At Exclaimer, one per email address that gets a signature, with ten minimum. Count your shared mailboxes before asking for quotes elsewhere: depending on the vendor they're in or out of the total, and that's where most price comparisons go wrong.
