Exclaimer Alternative: Signatoro

Exclaimer is a cloud platform for managing email signatures across a company. Signatoro is a generator that builds a signature and hands it to a person to paste into their own mail app. Here is how the two compare, checked on 18 September 2026.

Signatoro is one email signature that works in Gmail, Outlook and Apple Mail, priced by the size of the company: each person pastes it into their own mail app once, and it stays there. Exclaimer is a cloud email signature platform that applies signatures to mail as it passes through Exclaimer's own servers, built for centralized governance, banner campaigns and click analytics.

Choose Signatoro

a company is 50 people or fewer, wants a flat price set by its size, and would rather nothing about its mail routed through a third party's servers.

Choose Exclaimer

a company runs signature banner campaigns and needs click analytics and centralized governance across an organization large enough that Exclaimer's per-user price and ten-user minimum are not the constraint.

Signatoro and Exclaimer at a glance

Signatoro

Signatoro is an email signature generator: fill in your details, pick a layout, add a photo or a logo, and copy the result into Gmail, Outlook or Apple Mail, with a guide for each mail app. Signatoro never sits in the mail path, so each person's signature is pasted once and the mail keeps going the way it already went. Signatoro is free for one person, with a small Signatoro link under the signature, and a flat monthly price for a company by size: $9 up to 5 people, $19 up to 15 and $49 up to 50, plus $1.50 a month for each extra member.

Exclaimer

a cloud email signature platform that applies signatures to mail as it passes through Exclaimer's own servers, built for IT and marketing teams running centralized governance, banner campaigns and click analytics

Exclaimer is a cloud email signature platform used by IT and marketing teams for centralized signature governance, banner campaigns and click analytics. Exclaimer charges $0.90 to $1.75 per user a month on annual billing across its Starter, Standard and Pro tiers, plus a custom Enterprise tier, and every plan carries a minimum of ten users (Exclaimer's own pricing page, read 18 September 2026). Exclaimer used to sell an installed on-premises product, Signature Manager Exchange Edition, but discontinued it on 30 September 2022 and ended support on 30 September 2024; mail now routes through Exclaimer's own cloud datacenters, applied by a transport agent or connector rather than a locally installed program (Exclaimer's own support and product pages, read the same day).

Side by side

	Signatoro	Exclaimer
How does the signature get onto everyone's mail?	Signatoro never sits in the mail path. Each person builds their signature once and pastes it into their own mail app, so the mail keeps going the way it already went, with nothing of Signatoro's in between.	Exclaimer applies the signature as mail passes through Exclaimer's own cloud datacenters, using a transport agent or connector rather than an installed program, after discontinuing its on-premises product in 2022.
Is there a minimum number of people to sign up?	Signatoro has no minimum headcount on any plan: the free version covers one person, and the Company price applies from the first person.	Exclaimer's own FAQ states the minimum user count for Exclaimer is ten users, billed whether or not the company has ten people sending mail.
What does it cost?	Signatoro is free for one person, with a small Signatoro link under the signature, and a flat monthly price for a company by size: $9 up to 5 people, $19 up to 15 and $49 up to 50, plus $1.50 a month for each extra member.	Exclaimer charges $0.90 to $1.75 per user a month, billed annually across its Starter, Standard and Pro tiers, and every plan requires a minimum of ten users, so the smallest possible Exclaimer bill is $9 to $17.50 a month even for a company with three people (Exclaimer's own pricing page, read 18 September 2026).
What happens if the company stops paying?	Signatoro applies no signature itself; it only generates the text and image a person already pasted in. So if a company stops paying, nothing already pasted into a mail app breaks, and the next signature built reverts to the free version with the small Signatoro link.	Exclaimer's signature is applied on Exclaimer's own servers as mail passes through, so signing stops as soon as the subscription that keeps that transport agent running lapses.
Does it run banner campaigns and click analytics?	Signatoro builds and hosts the signature itself; it does not run banner campaigns or track clicks on them.	Exclaimer's own product pages describe centralized governance, banner campaigns and click analytics as core features, aimed at IT and marketing teams managing signatures at scale.
Does automated or AI-sent mail get the signature too?	Signatoro has a send-path API that a CRM, a sequencer or an assistant can call to fetch the saved signature, so mail an automated tool sends gets the same signature a person pasted in by hand, without routing that mail through Signatoro.	Yes, without extra setup. Because Exclaimer applies the signature to mail as it passes through Exclaimer's own transport agent, anything routed that way is signed regardless of what sent it, including mail sent by a CRM or an assistant.

When to choose Signatoro instead of Exclaimer

Nothing routes through Signatoro

Exclaimer signs mail on its own servers as it passes through; Signatoro signs nothing, because a person pastes the finished signature into their own mail app and Signatoro never sees that mail again. That structural difference is invisible until a company stops paying: Exclaimer's signing stops the day its subscription does, because the servers doing the signing are Exclaimer's, while a signature already pasted into a mail app keeps working under Signatoro, because nothing installed there was ever Signatoro's to turn off; the next signature built afterward reverts to the free version with the Signatoro link, but everything already sent stays as it was.

The New Outlook double-signing complaint

Exclaimer's own New Outlook add-in doubles or adds extra spacing to a signature when it collides with another signer on the same message, according to a thread in r/sysadmin and a related Spiceworks discussion cited in Signatoro's own content plan. Crossware, another vendor in Exclaimer's category, publishes its own troubleshooting article for the same mechanism, a signature appearing twice in Outlook because two things sign the same message, read 18 September 2026. Signatoro cannot produce this specific failure, because a signature pasted once into a mail app has no second, server-side signer behind it to collide with.

The ten-user floor

Exclaimer bills every plan for a minimum of ten users, so a six-person company on the Standard tier is billed for ten users at $1.45 each, $14.50 a month, the same $14.50 a nine-person company on that tier pays (Exclaimer's own pricing page, read 18 September 2026). A Spiceworks thread calls Exclaimer "too expensive just for signatures" for exactly this reason. Signatoro's Company price is set by the company's actual size instead, with no seat floor: six people cost $10.50 a month.

When to choose Exclaimer instead of Signatoro

Centralized governance, banner campaigns and click analytics

An IT or marketing team running signature banner campaigns across dozens or hundreds of users, and tracking clicks on them from one dashboard, is exactly who Exclaimer's product pages describe: campaign scheduling and click analytics built into the platform. What that team pays for it is Exclaimer's own shape: a per-user bill with a ten-user minimum, and every signature applied on Exclaimer's own servers as mail passes through rather than in each person's mail app. Signatoro does not run banner campaigns or track clicks on them, so that team's job is Exclaimer's to do.

One signature for mail sent by anything, with no integration

A company sending mail from several automated tools, a CRM, a sequencer, an assistant, and not wanting to configure a signature integration for each one individually, gets every one of them signed under Exclaimer without any setup, because the signature is applied to anything that passes through Exclaimer's transport agent regardless of what sent it. What that guarantee costs is the relay dependency this page keeps returning to: mail travels through Exclaimer's own servers to get it. Signatoro's send-path API reaches the same result without that dependency, but only for a tool that has actually been pointed at it; a tool nobody has integrated sends mail with no signature at all.

Questions about Signatoro and Exclaimer

What does Exclaimer cost for a small company?

Exclaimer charges $0.90 to $1.75 per user a month, billed annually, with a minimum of ten users on every plan, so a company with three or five people is billed the same $9 to $17.50 a month as a ten-person company (Exclaimer's own pricing page, read 18 September 2026). Signatoro's Company plan, by comparison, is a flat $9 a month for up to 5 people, set by the company's size rather than a seat floor.

What does Signatoro cost for a small company?

Signatoro is free for one person, with a small Signatoro link under the signature, and a flat monthly price for a company by size: $9 up to 5 people, $19 up to 15 and $49 up to 50, plus $1.50 a month for each extra member.

Does Exclaimer have a minimum number of users?

Exclaimer's own FAQ states the minimum user count for Exclaimer is ten users, and licensing is billed per active user regardless of how many people actually send mail (Exclaimer's own pricing page, read 18 September 2026). Signatoro has no minimum headcount on any plan; the free version covers one person and the Company price applies from the first person.

Why does my signature show up twice in the new Outlook?

Exclaimer's own New Outlook add-in doubles or adds extra spacing to a signature when it collides with another signer on the same message, according to a thread in r/sysadmin and a related Spiceworks discussion. Signatoro cannot produce this failure, because a signature pasted once into a mail app has no second, server-side signer behind it to collide with.

What happens to Exclaimer's signature if the company stops paying?

Exclaimer applies the signature on its own servers as mail passes through, so signing stops as soon as the subscription that keeps that transport agent running lapses. Signatoro applies no signature itself; it only generates what a person already pasted into their own mail app, so nothing already pasted breaks if a company stops paying Signatoro, and the next one built reverts to the free version with the Signatoro link.

Should a company switch from Exclaimer to Signatoro, or run both?

A company that needs Exclaimer's banner campaigns, click analytics or centralized governance at scale has a real reason to keep Exclaimer, and Signatoro does not do any of those three things. A company whose main complaint is the ten-user minimum, the per-user price, or mail routing through a third party's servers has a real reason to move to Signatoro's flat Company price instead. The two are not built to run side by side on the same users, since both would be adding a signature to the same mail.

Does either tool sign mail sent by a CRM or an AI assistant automatically?

Exclaimer does, without extra setup, because it applies the signature to any mail passing through its own transport agent regardless of what sent it. Signatoro does too, through a send-path API that a CRM, a sequencer or an assistant calls to fetch the saved signature, but only once that tool has been pointed at Signatoro's API.

Exclaimer's pricing, tier names and ten-user minimum are from exclaimer.com/pricing/, read 18 September 2026: per-user rates of $0.90 (Starter), $1.45 (Standard) and $1.75 (Pro), billed annually, plus a custom Enterprise tier, and the FAQ line "The minimum user count for Exclaimer is ten users." Exclaimer's discontinued on-premises product and its current cloud transport-agent architecture are from exclaimer.com/support/discontinued/ and exclaimer.com/product/signatures-for-exchange/, read the same day: Signature Manager Exchange Edition was discontinued 30 September 2022 with support ending 30 September 2024, and current signature application routes through Exclaimer's Azure datacenters via a transport agent or Exchange Online connector. Exclaimer's banner-campaign and click-analytics claim is from Exclaimer's own product pages, read the same day. The "too expensive just for signatures" complaint and the New Outlook double-signing complaint are sourced in Signatoro's own content plan (docs/product/content-plan.md), in the Reddit and forum enrichment table: a Spiceworks thread ("O365 sigs desktops/mobile/OWA") and an r/sysadmin thread (`exclaimer_signatures_in_new_outlook`) respectively; Pillar 6 of the same plan carries the paraphrased version of both, without naming the threads. This page adds, as independent corroboration rather than the original source, that Crossware, another vendor in Exclaimer's category, publishes its own troubleshooting article for the same two-things-signing-one-message mechanism, read 18 September 2026. A CodeTwo article on double signatures also turned up in the same search; it was not used, because the live CodeTwo article found describes a different mechanism, Microsoft's roaming-signature sync corrupting a local signature file, not two signers colliding.
