The right Signature Satori alternative depends on why you’re leaving. Signitic and Newoldstamp are the closest swaps for Gmail signatures with banner campaigns. Exclaimer suits mixed Microsoft 365 and Google estates and teams that want signatures added after send. Patronum suits Google Workspace teams that want signatures run alongside onboarding, offboarding and Drive sharing.

Patronum makes Google Workspace management software and wrote this comparison. Facts about other products come from their public pages, checked 13 Nov 2026.

What is Signature Satori, and what does it cost?

Signature Satori is a Google-only signature manager from AppSatori s.r.o. Its pricing page says it uses the Gmail API with no SMTP configuration or routing through third-party servers, and its home page says its servers are hosted on Google’s infrastructure (Signature Satori). It imports users, custom fields and organizational units from the Google Directory, supports Send-as addresses, and offers a drag-and-drop editor with an HTML view, conditional content, a self-service page for employees, and a marketing planner with a built-in Canva banner editor and Google Analytics link tracking (Signature Satori pricing).

Satori sells two models, in USD or EUR, excluding VAT:

Credits: a one-time purchase, minimum 10. One credit sets or changes one user’s signature, with a 24-hour window for further edits.
Subscription: a monthly payment per user, minimum 5, with unlimited changes, the Marketing Planner and a daily sync from the Google Directory to Gmail.

The per-unit price falls with volume. On 13 Nov 2026 the pricing calculator showed these USD subscription prices:

Users	Per user per month	Monthly total
5 (minimum)	$1.11	$5.55
50	$1.02	$51
100	$0.93	$93
500	$0.58	$290

Credits followed the same unit prices (100 credits showed $93, one time). Above 1,000 users or credits, Satori asks you to contact it. You can also subscribe only some users and use credits for the rest. New accounts get 5 free credits.

On a phone? The same comparison, vendor by vendor:

Signature Satori: Gmail API; OUs and Google Groups; banner planner with Canva; per user per month or one-time credits, USD or EUR.
Patronum: Gmail API; OU or Group scope narrowed by attributes; banners in the HTML template with UTM tracking; $8 per active Workspace user per year (Business).
Exclaimer: in-compose or after-send cloud deployment; user, role, department or recipient targeting; campaigns from Standard; $0.90 to $1.75 per mailbox per month, 10-user minimum.
WiseStamp: Google integration or server-side on higher plans; departments and targeting rules; campaigns from Grow; base fee plus $1 per employee per month.
Signitic: Marketplace app; groups; campaigns with A/B testing on Standard; €1 per user per month, free up to 19 employees.
Newoldstamp: Gmail API connection; departments; scheduled campaigns; per signature, billed annually, custom above 200.

Each fact is linked in the sections below. “Not documented” means we couldn’t find it on the vendor’s public pages, not that the feature doesn’t exist.

How we judged them

We included only tools that document organization-wide deployment for Google Workspace, and checked each vendor’s own pages for how signatures reach Gmail, directory data, targeting, campaign tooling and pricing. This is a documentation review, not a hands-on test.

We left out CodeTwo. A June 2024 post said its Google Workspace signatures were on the way (CodeTwo blog), but its signature product page still covers Microsoft 365 and Exchange only (CodeTwo).

How quickly do signature changes reach Gmail?

“Hourly versus daily” isn’t a fair verdict on its own, because three separate clocks are involved:

Directory refresh: how often the tool reads updated names and titles. Satori’s Subscription syncs daily. Patronum’s policy preview uses directory data cached and refreshed hourly. For the other vendors, we did not find a sync frequency on the pages reviewed.
Policy execution: when the tool writes the signature. Patronum policies run on an hourly cycle, with up to 60 minutes before a new policy’s first run (Patronum Help). Satori describes enforcement by a recurring daily set-up. Server-side tools such as Exclaimer’s cloud deployment add the signature at send time instead.
Gmail display: Patronum’s help center notes Gmail itself may cache signatures for 1 to 2 hours after an update (Patronum Help).

If timing matters, change one pilot user’s job title and time how long it takes to appear in a sent message.

Which Signature Satori alternative suits which team?

Patronum: signatures as part of Google Workspace management

Suits: Google Workspace teams that want signatures handled in the same tool as onboarding, offboarding, shared contacts and Drive sharing.

Patronum applies Gmail signatures by policy through the Gmail API, building each from the Google Directory and overwriting a user’s manual edits on the next sync (Patronum Help). Its marketing page says no SMTP or SPF changes are needed (Patronum). A custom Patronum role can let marketing manage only signatures for a set of users (Patronum Help).

Pricing and licensing: the public pricing page shows the Business plan at $8 per user per year and doesn’t say which plan includes each capability (Patronum pricing). Patronum requires a license for every active Google Workspace user (Patronum Help). That changes the comparison: Satori, Exclaimer, Signitic and Newoldstamp can count only the people or mailboxes that get a signature, while Patronum counts your whole active user base.

Not documented: a banner scheduler, A/B testing, in-app click analytics or a drag-and-drop editor. Banners go into the HTML template and are tracked with UTM codes in Google Analytics (Patronum Help). Patronum also can’t set Gmail’s separate reply and forward default, a Gmail API limitation (Patronum Help).

Exclaimer: the broadest signature specialist

Suits: mixed Microsoft 365 and Google Workspace companies, and teams that want a disclaimer on every message.

Exclaimer documents two deployment models for Google Workspace: device deployment, which shows signatures in Gmail while composing, and cloud deployment, which adds them after send and which Exclaimer says covers messages from any device. Cloud deployment runs through Exclaimer’s service on Microsoft Azure datacenters, so your mail flow passes through it (Exclaimer). Legal disclaimers are listed on every plan, scheduled campaign banners start at Standard, and licensing counts active mailboxes that get a signature (Exclaimer pricing).

Trade-off: the cloud model is the mail routing many Satori users chose to avoid; device deployment avoids it.

WiseStamp: marketing features on a platform fee

Suits: marketing-led teams that want campaigns, surveys and analytics.

Every business plan includes the Google Workspace integration and departments; campaigns and analytics start at Grow ($49 base) (WiseStamp pricing). WiseStamp’s help center says the Google integration applies signatures in Gmail web and iOS, while server-side deployment, on Platform and Enterprise, routes mail to WiseStamp after your mail server and needs mail server configuration (WiseStamp Help).

Trade-off: the monthly base fee weighs most on small teams.

Signitic: a like-for-like swap for small and mid-size teams

Suits: teams that want directory sync, banner campaigns and A/B testing, with a free tier for small offices.

The Free plan covers up to 19 employees with one template, one campaign and a Signitic badge. Standard adds unlimited templates, campaigns and groups (Signitic pricing). Its Marketplace listing describes a drag-and-drop editor and directory sync, and the app requests access to Gmail settings (Google Workspace Marketplace).

Trade-off: pricing is in euros, the billing period isn’t stated, and a server-side option for Gmail isn’t documented.

Newoldstamp: per-signature pricing for marketing use

Suits: smaller marketing-driven teams that count signatures rather than users.

Newoldstamp imports data from the Google Workspace Directory, supports a different signature per department, and says it connects to Google Workspace through the API to add and update signatures (Newoldstamp). On 13 Nov 2026 its pricing slider showed $1,519 a year for 95 signatures and $1,599 for 100, about $1.33 per signature per month; the slider rounds this to $1.3. Smaller plans cost more per signature, and above 200 you need a quote (Newoldstamp pricing).

What would 100 signatures cost?

One scoped example: a company where 100 people need managed signatures, at list prices on 13 Nov 2026, before tax, as a yearly figure.

Tool and plan	Unit counted	Yearly list price
Signature Satori Subscription	User (monthly)	$1,116 ($93 a month)
Exclaimer Starter, Standard or Pro	Active mailbox	$1,080, $1,740 or $2,100
WiseStamp Basic	Base fee plus employee	$1,428
Newoldstamp	Signature	$1,599
Signitic Standard	License	€1,200 if paid for 12 months
Patronum Business	Every active Workspace user	$800 if you have exactly 100 active users

Read it with care. Features differ by plan, Signitic is priced in euros, and Patronum counts every active user: if only 100 of 400 users need signatures, Patronum’s Business plan comes to $3,200. Patronum also offers wider Workspace management capabilities; confirm which are included in the quoted plan. Basic Google Drive management is listed for both Patronum plans, while advanced Drive governance, such as file compliance automation, automated file expiry and custom file governance policies, is a Patronum Plus feature (Patronum Help). Satori credits may cost less than a subscription when updates are infrequent. There’s no single cheapest tool; price your own headcount and unit.

When should you stay on Signature Satori?

Plenty of teams should. Stay if:

Your signatures rarely change: credits may cost less than a subscription when updates are infrequent.
Only some staff need managed signatures, and you want to pay for just those users.
You rely on the self-service page, the drag-and-drop editor or the Canva banner editor.
Your campaigns run through the Marketing Planner and a daily sync is fast enough.

How do you switch from Signature Satori to Patronum?

Most of the work is mapping placeholders, because different tools use different placeholder syntax (Patronum Help).

Move data into the Google Directory. Patronum reads the Directory, including custom schema extensions. Export anything you typed into Satori directly.
Paste each template’s HTML and swap placeholders for Patronum’s, such as {{fname}} and {{jobTitle}} (Patronum Help).
Pilot with a Google Group, after removing the same people from Satori so two tools don’t write the same signature. Check a new message and a reply, then widen the scope.
