Exclaimer
Cloud email signature management for Microsoft 365, Google Workspace and Exchange, with server-side or Outlook deployment.
exclaimer.com8.9
out of 10
Best for: IT teams that want central control of every signature across mail platforms and devices.
Exclaimer is the most complete option for IT teams that need one signature policy across every mailbox. It connects to Microsoft 365, Google Workspace and Exchange, and every plan can apply signatures on the server, inside Outlook, or both, so messages sent from phones get the same footer as desktop mail. Employee details update automatically from the directory, and Pro can fill Active Directory gaps from an HRIS or a CSV file. Marketing gets scheduled banners, brand kits and, on Pro, engagement data plus Salesforce and HubSpot list targeting. Pricing is published and low: Starter costs $0.90 per user per month billed annually, Standard $1.45 and Pro $1.75, with a 14-day trial. The main trade-off is that the useful marketing features sit on the upper tiers, and Starter is limited to one brand kit. Larger rollouts with staged deployment and a dedicated success manager move to quoted Enterprise pricing.
Standout feature
Every plan can deploy server-side, client-side or both.
Use cases
IT admins
Apply one compliant signature to every mailbox, including mobile
Outcome: No more chasing staff to update footers
Marketing teams
Schedule banners for an event by region
Outcome: Campaigns go live on every email at once
Compliance leads
Add legal disclaimers to all outbound mail
Outcome: Consistent disclaimers without user action
Key features
- Signatures applied server-side, client-side in Outlook, or both
- Auto-updated employee details from the directory, with HRIS or CSV import on Pro
- Scheduled signatures and campaign banners by department or team
- Brand Kits for logos, colors and fonts, unlimited on Pro
- Salesforce and HubSpot recipient list targeting on Pro
Pros
- Lowest published entry price in this list at $0.90 per user
- Works with Microsoft 365, Google Workspace and Exchange
- Lists SOC 2, ISO/IEC 27001, 27018 and HIPAA among its compliance credentials
Cons
- Starter has one Brand Kit and limited templates
- CRM targeting and engagement data are reserved for Pro
- Hands-on rollout help needs the quoted Enterprise tier
Rank 2 · Runner-up
CodeTwo Email Signatures 365
Single-plan signature service built for Microsoft 365, adding signatures in the cloud or in Outlook as users type.
codetwo.com8.8
out of 10
Best for: Microsoft 365 organizations that want every feature in one plan without tier decisions.
CodeTwo takes a simple approach: one plan, all features, priced per license with volume discounts. It is built for Microsoft 365 and can add signatures in the cloud for mail from any app or device, or inside Outlook so users see the signature while they type. Admins get unlimited templates, rule-based targeting by sender or recipient, scheduling, legal disclaimers and centrally managed auto-replies. Marketing features include scheduled banner campaigns, QR codes and vCards, and the service has built-in customer satisfaction analytics, which few rivals bundle. Pricing starts at a minimum of 10 licenses and drops per user as you add more, with a yearly plan about 10% cheaper than monthly; we could not confirm the USD figures in a page fetch from our location, so treat the price as pending. The 14-day trial needs no credit card. The limit is scope: if part of your company runs on Google Workspace, look at Exclaimer or Letsignit instead.
Standout feature
Customer satisfaction analytics are built into the signature service.
Use cases
Microsoft 365 admins
Roll out signatures for 200 mailboxes without tiers to compare
Outcome: One license type covers everything
Support managers
Add satisfaction surveys to agent signatures
Outcome: Feedback collected from everyday replies
Office managers
Set company auto-replies during holidays centrally
Outcome: Consistent out-of-office messages
Key features
- Centrally managed signatures, legal disclaimers and auto-replies
- Unlimited signature templates with rule-based targeting and scheduling
- Signatures added in the cloud or in Outlook while users type
- Scheduled email marketing campaigns with banners, QR codes and vCards
- Built-in customer satisfaction analytics
Pros
- One plan with every feature, so no upgrade surprises
- Volume discounts, with a lower per-user price above 100 licenses
- 24/7 support by email and phone
Cons

- Minimum of 10 licenses
- Above 500 licenses pricing is by quotation
Rank 3 · Also great
Letsignit
Email signature, vCard and PowerPoint brand platform for Microsoft 365 and Google Workspace, created by a long-time Microsoft partner.
letsignit.com8.6
out of 10
Best for: Marketing and communications teams that want to run signature campaigns while IT keeps control.
Letsignit is built for the handoff between IT and marketing. IT connects Microsoft 365 or Google Workspace and keeps control of access and data, while communications teams design signatures, run targeted campaigns and measure them without filing tickets. The designer supports drag and drop and HTML import with unlimited templates, campaigns can be A/B tested and include dynamic polls, and native analytics report on performance. Letsignit also sells digital business cards for Apple and Android wallets and a PowerPoint product that locks fonts, colors and layouts, which suits brand teams that want one tool for employee touchpoints. The signatures and vCards plan is listed at $2 per user per month, and a free trial is offered. Bigger companies needing roles, permissions, multi-directory sync through SCIM or on-premise deployment move to quoted Enterprise pricing. The entry price is more than double Exclaimer's, so it pays off mainly when marketing will actually run campaigns.
Standout feature
Signature campaigns support A/B testing and dynamic polls.
Use cases
Brand teams
Test two banner designs on outbound email
Outcome: Pick the version that gets more clicks
Sales staff
Share a vCard from a phone wallet
Outcome: Contacts saved without typing
Multi-entity groups
Sync several directories on Enterprise
Outcome: One platform across subsidiaries
Key features
- Drag and drop signature designer with HTML import and unlimited templates
- Targeted campaigns with A/B testing and dynamic polls
- Digital business cards (vCard) in Apple and Android wallets
- Native performance analytics
- Enterprise multi-directory sync via API and SCIM, with on-premise and SMTP options
Pros
- Lets marketing manage signatures while IT retains access control
- A/B testing and polls inside signature campaigns
- ISO 27001 and 27018 certified, per the vendor
Cons
- Higher entry price than Exclaimer or CodeTwo
- Governance, roles and multi-directory sync need the quoted Enterprise plan
- Slides and signatures are priced as separate products unless you buy the Platform plan
Rank 4
WiseStamp
Email signature platform for teams on Google Workspace and Microsoft 365, plus a Pro+ plan for individuals and micro-teams.
wisestamp.com8.5
out of 10
Best for: Small and midsize businesses that want quick setup with an AI designer and banners.
WiseStamp began as a personal signature tool and now sells company plans that connect to Google Workspace and Microsoft Entra to install signatures, add new hires and keep employee details current. Its AI Signature Designer is included from the Basic plan, which makes it one of the fastest tools to set up for a team without a designer. Pricing combines a base fee with a per-employee charge: Basic is $19 per month plus $1 per employee billed annually with one admin and five templates, Grow is $49 per month plus $1 per employee and adds banner campaigns, click analytics and automated rules, and Platform at $189 per month adds roles, SSO and server-side deployment. Individuals and micro-teams can use Pro+ from $9 per month. The structure works well for 30 to 300 people, but the base fee makes it pricier than Exclaimer for tiny teams, and IT teams that require server-side signatures must buy the top tier.
Standout feature
AI Signature Designer is included from the Basic plan.
Use cases
Startup founders
Give 25 employees matching signatures in an afternoon
Outcome: Consistent branding without a designer
Marketing managers
Promote a webinar with a banner on Grow
Outcome: Clicks tracked from everyday email
Agencies and freelancers
Use Pro+ for a small team
Outcome: Low monthly cost
Key features
- AI Signature Designer on every company plan
- Google Workspace and Microsoft Entra integrations that add new hires and keep details current
- Targeted banner campaigns and click analytics on Grow
- Rules that swap signatures automatically
- Server-side integration, SSO, roles and audit log on Platform
Pros
- Very quick to set up for small teams
- 14-day trial with no credit card
- Lists SOC 2 Type II, ISO 27001 and HIPAA standards for its hosting
Cons
- Base fee plus per-employee charge costs more than rivals for small headcounts
- Campaigns and analytics start on Grow at $49 per month plus $1 per employee
- Server-side deployment sits on the top Platform plan
Rank 5
Rocketseed
Server-side email signature and banner platform for Microsoft 365, Google Workspace and Exchange with CRM-linked analytics.
rocketseed.com8.4
out of 10
Best for: Companies of 50 or more people that want server-side signatures with no add-ins.
Rocketseed is a server-side tool: it connects to Microsoft 365, Google Workspace or Exchange and stamps signatures on mail as it passes through, so there are no add-ins to install and nothing for employees to configure. Signatures sync with Active Directory, Microsoft Entra ID or Google Directory, and rules assign the right design by brand, domain or team. Marketing banners come with real-time analytics, and integrations with Salesforce, HubSpot and Google Analytics let teams follow clicks through to conversions. Rocketseed says pricing starts at approximately $1 per user per month with all features included and no tiered gates, which keeps budgeting simple, but the word approximately means you still need a quote. The 14-day trial is offered to teams of 50 or more, and setup includes signature design and training. That service-led approach suits midsize firms that want a vendor to handle rollout, less so a ten-person office.
Standout feature
All features are included at one per-user price.
Use cases
IT managers
Deploy signatures with no Outlook add-in
Outcome: Zero end-user setup
Multi-brand groups
Assign signatures by domain and brand
Outcome: Each company keeps its identity
Revenue marketers
Track banner clicks into HubSpot
Outcome: Signature campaigns tied to pipeline
Key features
- Server-side deployment across Microsoft 365, Google Workspace and Exchange
- Directory sync with Active Directory, Microsoft Entra ID or Google Directory
- Rule-based signature assignment with multi-brand and multi-domain support
- Marketing banners with real-time analytics
- Salesforce, HubSpot and Google Analytics integrations
Pros
- No add-ins or end-user installs
- All features included, no tiered feature gates
- ISO 27001 certified, per the vendor
Cons
- Published price is approximate, so a quote is still needed
- Trial and onboarding are aimed at teams of 50 or more
- Custom pricing for 200+ users
Rank 6
Signitic
European email signature manager with a free plan for small teams and CRM targeting for Google Workspace and Microsoft 365.
signitic.com8.4
out of 10
Best for: Small teams that want a free start, and EU companies that prefer European hosting.
Signitic is a French signature manager that gives small companies a real free plan: up to 19 employees, one signature template and one banner campaign, with a Signitic badge under the signature. Paid plans connect to Google Workspace and Microsoft 365 to deploy consistent signatures and campaigns across the organization, and links can carry generated UTM tags so results show up in Google Analytics. Higher tiers add CRM-based signatures and targeting with HubSpot, Salesforce and Marketo, plus HRIS and SFTP integration and vCards. The company says it is ISO 27001 certified with infrastructure hosted in Europe, which matters to EU buyers with data residency rules. Pricing is published only in euros, so we list the paid price as pending in USD. The free plan is a good test, but its badge and one-template limit mean most companies will move to Standard once they need department variants.
Standout feature
A free plan covers up to 19 employees.
Use cases
Small agencies
Give 15 people branded signatures at no cost
Outcome: Consistency on the free plan
EU IT teams
Keep signature data hosted in Europe
Outcome: Simpler GDPR reviews
Growth marketers
Tag signature links with UTMs
Outcome: Banner traffic visible in Google Analytics
Key features
- Google Workspace and Microsoft 365 integrations
- Banner campaigns with UTM generation for Google Analytics
- CRM signatures and targeting with HubSpot, Salesforce and Marketo on higher plans
- vCard digital business cards
- HRIS and SFTP premium integration
Pros
- Free plan for up to 19 employees
- ISO 27001 certified with European hosting, per the vendor
- Part of the Positive group with Surfer and Iconosquare
Cons
- Free plan has one template, one campaign and a Signitic badge
- Prices are shown in euros only
- CRM targeting requires the custom tier
Rank 7
Signature 365
Symprex's cloud email signature, campaign and disclaimer service designed for Microsoft 365.
signature365.com8.2
out of 10
Best for: Microsoft 365 organizations up to about 500 users that want one all-features price.
Signature 365 is the cloud signature product from Symprex, which also sells an on-premises Email Signature Manager for Exchange Server. It is designed only for Microsoft 365: mail routes through the service, or users run the Outlook add-in, and signatures, campaigns and legal disclaimers are added centrally. The dashboard has a template library, department segmentation and built-in tracking, analytics and reporting for banners. The pricing model is a single plan with every feature and a 20% saving for annual billing, plus volume discounts and reduced rates for healthcare, education, government and nonprofits. Licensing counts each user and each shared mailbox routed through the service. The checkout page computes prices in the browser, so we could not confirm a USD figure and list it as pending. The 14-day trial needs no card. It is a sensible, compliance-minded choice for Microsoft 365 shops under 500 users, but offers fewer marketing extras than Exclaimer or Letsignit.
Standout feature
Symprex also sells an on-premises edition for Exchange Server.
Use cases
Healthcare IT
Add compliant disclaimers to every email
Outcome: Discounted pricing for the sector
Small Microsoft 365 firms
Start a free 14-day trial with no card
Outcome: Quick proof before buying
Department heads
Segment signatures by department
Outcome: Each team shows its own details
Key features
- Central dashboard with easy-to-customize templates
- Marketing campaigns with tracking, analytics and reporting
- Legal disclaimers appended to email
- Segmentation by department
- Works through the cloud service or an Outlook add-in
Pros
- All features in one price, with 20% off annual billing
- ISO 27001, ISO 27018 and SOC 2 certified, per the vendor
- Volume and nonprofit discounts
Cons
- Microsoft 365 only
- Contact sales above 500 users
- Shared mailboxes routed through the service need their own license
Rank 8
MySignature
Signature generator with 100+ templates and link tracking, plus central management for Google Workspace and Microsoft 365 teams.
mysignature.io8.1
out of 10
Best for: Freelancers and small teams that want a free start and click tracking.
MySignature is the easiest tool in this list to start with. Its free generator turns a template into HTML in minutes, and the editor can suggest colors, layout and borders in one step. There are more than 100 templates, and you can add banners, call-to-action buttons, booking links and legal disclaimers. Every link in a signature is tracked, so the dashboard shows which banner or button gets clicked, and a Gmail tracker is available. Paid plans remove MySignature branding and add advanced designs, analytics and team features. Individuals and teams of 5 to 25 manage signatures from one account, while larger companies on Google Workspace or Microsoft 365 get centralized management. The pricing page loads in the browser, so we list it as USD pending. MySignature is a good fit for marketing-minded small teams, but IT departments needing server-side rules, Exchange support or compliance documentation should start with Exclaimer or CodeTwo.
Standout feature
Every link in the signature is tracked automatically.
Use cases
Freelancers
Build a branded signature free in minutes
Outcome: Professional look at no cost
Small sales teams
Track which banner gets clicks
Outcome: Know which offer works
Growing teams
Move to central management on Google Workspace
Outcome: Updates reach everyone automatically
Key features
- 100+ editable email signature templates with automatic HTML code
- Tracking on every link, button, banner and social icon
- Banners, call-to-action buttons and disclaimers
- Centralized management for Google Workspace and Microsoft 365 teams
- Installs in Gmail, Outlook, Apple Mail and Thunderbird
Pros
- Free plan to create a signature
- Very easy editor with AI color and layout suggestions
- Built-in click analytics
Cons
- Free signatures carry MySignature branding
- Central management is limited to Google Workspace and Microsoft 365
- Fewer compliance and directory controls than IT-focused tools
Rank 9
Newoldstamp
Email signature generator and manager for teams, with Google Workspace, Microsoft 365 and Exchange deployment and banner campaigns.
newoldstamp.com8.1
out of 10
Best for: Teams of up to 200 people that want a signature editor plus banner campaigns.
Newoldstamp grew from a popular signature generator into a management tool for teams. Admins design signatures in its generator, push them automatically to Google Workspace, Microsoft 365 or Exchange, and run banner campaigns that can be scheduled and segmented by audience, with analytics on clicks. A custom generator lets employees build their own signatures inside brand rules, which helps companies where staff use many different email clients; Newoldstamp lists Gmail, Outlook, Apple Mail, iOS, Thunderbird, Zoho Mail and others. Pricing is per signature per month on a slider up to 200 signatures, billed annually, with custom plans above that. The price updates in the browser, so we list it as USD pending. The 7-day trial is the shortest here. Newoldstamp is a practical choice for small and midsize businesses, though it lacks the compliance credentials and directory controls larger IT teams expect.
Standout feature
Employees can build their own signatures inside brand rules.
Use cases
Small marketing teams
Schedule a seasonal banner for one segment
Outcome: Targeted promotion in daily mail
Mixed-client offices
Install signatures across Gmail, Outlook and Apple Mail
Outcome: One look on every client
HR coordinators
Let new hires create a branded signature
Outcome: No admin ticket needed
Key features
- Advanced signature generator with brand templates
- Automatic deployment to Google Workspace, Microsoft 365 and Exchange
- Banner campaigns with scheduling and audience segmentation
- Signature performance analytics
- Custom generator so employees build branded signatures themselves
Pros
- Works with many email clients including Gmail, Outlook, Apple Mail and Thunderbird
- Self-serve generator for employees
- Clear per-signature pricing up to 200 users
Cons
- Only a 7-day trial
- Over 200 signatures needs a custom plan
- Fewer enterprise controls than Exclaimer or Letsignit
Rank 10
Opensense
Enterprise email signature and engagement platform with GCC High support, CRM integrations and email tracking.
opensense.com7.9
out of 10
Best for: Large and regulated organizations, including US government contractors on GCC High.
Opensense treats signatures as a channel for revenue teams as well as an IT control. Its Signature IT and Branding plan covers centrally managed, compliant signatures for Microsoft 365, with Entra ID sync, SCIM and SSO, and Google Workspace with directory sync and analytics. Higher plans add targeted email ad campaigns and integrations with HubSpot, Salesforce, Marketo and other systems, and separate email tracking plans serve inside sales teams. Opensense also sells GCC High signatures for organizations under FedRAMP High, DFARS, ITAR or CMMC rules, which almost no rival in this list addresses. The price starts at $1 per user per month, but every plan carries a $500 per month minimum plus a platform license, so a 100-person company pays the minimum regardless. That minimum, and a demo-led sales process, put Opensense out of reach for small teams and lower its value score, even though its feature set is among the deepest here.
Standout feature
Supports GCC High tenants for regulated federal organizations.
Use cases
Defense contractors
Manage signatures in a GCC High tenant
Outcome: Compliant branding for federal work
Demand generation teams
Run account-targeted banners from HubSpot data
Outcome: Email becomes an ad channel
Enterprise IT
Sync users through SCIM and SSO
Outcome: Automated provisioning
Key features
- Microsoft 365 signatures with Entra ID sync, SCIM and SSO, GCC High compatible
- Google Workspace signatures with Google Directory sync and analytics
- Targeted email ad campaigns on Pipeline Marketing Pros
- Integrations with HubSpot, Salesforce, Marketo and Microsoft 365
- Auto disclaimers, audit logs and SOC 2 Type II certification
Pros
- GCC High and FedRAMP High options for regulated federal work
- Deep CRM and marketing automation links
- Email tracking plans for sales teams
Cons
- $500 per month minimum plus a platform license rules out small teams
- Demo-led buying, no self-serve signup
- More complex than tools built only for consistency
