Updated . Built on 6 November 2026 from Signatoro's public Zoho Mail guide and admin guide, Signatoro's own screenshots from its Zoho Marketplace listing, and real Zoho Mail settings screens (looked at only, nothing changed). The install click and Zoho's consent screen follow Signatoro's docs; we did not run the install for this lesson. How we check this lesson
If everyone in your office typed their own Zoho Mail signature, every new phone number or logo means chasing each person, and some never update. In this free lesson you follow Lena Ortiz (made up), office manager at Kestrel Architects, nine people on Zoho Mail. She saves the signature in Signatoro, where a Company plan sets the logo, colors and company details once, clicks Install into my Zoho Mail, and reads the three permissions Zoho asks her to approve. Then she opens Zoho Mail's Settings > Signature to see where the signature lands, which From address it is linked to, and whether replies and forwards get it too.

The business case: nine signatures that drift apart
Kestrel Architects changes something about its signature about three times a year: a new phone line, a new logo, a new title. Updating and chasing nine people takes about 20 minutes per person per change, about 9 hours a year, and a month later two people still have the old version, or Zoho's default Sent using Zoho Mail.
Signatoro keeps each person's signature in one place, with the company's parts set once. Its Zoho Mail install writes that signature into Zoho Mail, and every later change, the person's or the company's, reaches Zoho Mail by itself.
What you do in the lesson
Signatoro's guide has the install in three steps: sign in to Signatoro and open your signature page, click Install into my Zoho Mail on the Zoho Mail card, then sign in to Zoho if asked and approve access. On a Company plan, the company name, website, logo, layout, color and font say Set by your company; each person fills in only their own details.
Zoho's consent screen lists three permissions: view mail account information, create, and update. Signatoro's admin guide says it uses them only to find the address you send from, add a signature named Signatoro, and keep it updated, and that it leaves every other signature in the mailbox alone. Afterwards the card says Installed in Zoho Mail, It updates itself, with a Disconnect button.
Checking it in Zoho Mail
In Zoho Mail, the Settings gear on the right opens Settings, and Signature is in the Mail section of the menu. The list shows every signature in the mailbox; a new mailbox has only Zoho's default, Sent using Zoho Mail, and after the install a signature named Signatoro sits there too.
Zoho adds a signature to new emails only when it is linked to your address under Associated From addresses for new emails, and the install sets that for you. The gear next to Signature holds Add signature to all my email replies and forwards: if it is not ticked, replies go out unsigned. The Zoho Mail phone app takes the signature only after you sync its settings from the web.
