Admins control every signature from a single portal — consistent branding, legal disclaimers, and campaign banners across the whole organisation, no matter what device or Outlook client employees use. No mail rerouting. No server-side processing of email content. No complex setup. Just consistent, compliant signatures — managed centrally, delivered privately. Built for companies that take data protection seriously. #### Who Is the Company Behind SigHQ? - **Seller:** [FifteenK](https://www.g2.com/sellers/fifteenk) - **HQ Location:** N/A - **LinkedIn® Page:** [www.linkedin.com](https://www.g2.com/external_clickthroughs/record?secure%5Bsource_type%5D=product_profile&secure%5Btoken%5D=7886df2ed926834e5eb248c77dcfa8e5c815d3ab1f0fe3132ced0dba45868834&secure%5Burl%5D=https%3A%2F%2Fwww.linkedin.com%2Fcompany%2FNo-Linkedin-Presence-Added-Intentionally-By-DataOps&secure%5Burl_type%5D=linkedin_company_website) 1 employees on LinkedIn® ### [Sigil](https://www.g2.com/products/tophhie-cloud-sigil/reviews) Sigil is an email signature management platform built specifically for Microsoft 365 organisations. Admins design and manage signature templates centrally — including drafts, versioning and rollback — and Sigil applies them automatically in Outlook as each user composes a message, personalised per person from Microsoft Graph directory data (name, job title, department, phone numbers, and more). What sets Sigil apart is visibility: most signature tools can tell you a signature was served, but not whether it actually applied. Sigil's per-mailbox adoption telemetry closes that gap, surfacing exactly which users have never successfully received a signature — so IT teams can fix silent failures before a client or colleague notices a missing signature first. Sigil also includes assignment rules (by department, office, domain or Entra group), time-boxed campaign banners, privacy-preserving link-click analytics, per-domain compliance footers, and role-based access for admins, editors and marketing users — all for one flat price per licensed mailbox, with shared and resource mailboxes free. #### Who Is the Company Behind Sigil? - **Seller:** [Tophhie Cloud](https://www.g2.com/sellers/tophhie-cloud) - **HQ Location:** N/A - **LinkedIn® Page:** [www.linkedin.com](https://www.g2.com/external_clickthroughs/record?secure%5Bsource_type%5D=product_profile&secure%5Btoken%5D=7886df2ed926834e5eb248c77dcfa8e5c815d3ab1f0fe3132ced0dba45868834&secure%5Burl%5D=https%3A%2F%2Fwww.linkedin.com%2Fcompany%2FNo-Linkedin-Presence-Added-Intentionally-By-DataOps&secure%5Burl_type%5D=linkedin_company_website) 1 employees on LinkedIn® ### [Signature.email](https://www.g2.com/products/signature-email/reviews) A powerful visual drag and drop editor for email signatures paired with the easiest way to maintain consistency for your whole team. #### Who Is the Company Behind Signature.email? - **Seller:** [Switchback Interactive](https://www.g2.com/sellers/switchback-interactive) - **HQ Location:** Minneapolis, US - **LinkedIn® Page:** [www.linkedin.com](https://www.g2.com/external_clickthroughs/record?secure%5Bsource_type%5D=product_profile&secure%5Btoken%5D=05801324f526510b5de89377f70769c6b71f8dbd30b48fab7fc5a3de095b5026&secure%5Burl%5D=https%3A%2F%2Fwww.linkedin.com%2Fcompany%2Fsignature-email%2F&secure%5Burl_type%5D=linkedin_company_website) 2 employees on LinkedIn® ### [StampyMail](https://www.g2.com/products/stampymail/reviews) StampyMail es una plataforma web para crear, gestionar y desplegar las firmas de email de cualquier organización de forma centralizada, rápida e intuitiva desde cualquier dispositivo pc o móvil.
