What is MailSignatures.io?
MailSignatures.io writes signatures straight into Gmail through a Google Workspace admin approval, so nothing is installed by employees. It pulls names, titles and photos from the directory and applies a chosen style to every mailbox. A separate Solo plan covers one personal @gmail.com account.
Worth knowing
- It is built for Gmail and Google Workspace only; the pages describe no Outlook or Microsoft 365 support.
- The prices shown are on annual billing; only the Solo plan's month-to-month price ($4) is stated in the FAQ.
- Priority support and setup guidance start at the Business plan.
- Invoicing, vendor onboarding and help with larger deployments are handled by contacting the vendor.
Key features
- Direct Gmail sync
- Signatures are written to each user's native Gmail settings via Google Workspace, with no browser extension and no change to email delivery.
- Directory-fed details
- Names, titles and photos are pulled from the Workspace directory, and seats stay in sync with the Workspace user list.
- Three signature styles
- Every Workspace plan includes all three signature styles, social links, brand color and logo, and shared company fields.
- Multiple domains and aliases
- Secondary domains each get their own branded design, kept in sync alongside the main domain.
- Preview before applying
