Connect Zoho Mail to Linkubit

Sign in to Zoho to send from your own Zoho Mail address; replies come back on their own. What Zoho can and cannot carry, and the data-centre note.

In short

Go to Settings › Email, choose Zoho Mail and sign in. Linkubit sends from your address and reads replies directly — no forwarding rule. Zoho's API cannot carry an unsubscribe header or threading headers, so Linkubit adds an unsubscribe link to the body instead.

Connect

  1. Open Settings › Email and choose Zoho Mail ("Replies come back on their own").
  2. Sign in to Zoho in the same tab and allow access to send, read messages and list folders.
  3. Back on Settings › Email, press Send myself a test and reply to it.

What is different on Zoho

  • No forwarding step — Linkubit reads replies from the mailbox.
  • Unsubscribe in the body — Zoho's API takes no custom headers, so the one-click unsubscribe header Gmail gets is replaced by an "Unsubscribe" link at the end of the email.
  • No threading headers — a reply in the customer's mail app may start a new thread rather than nest under yours.
  • Same daily ramp as Gmail — 50 on day one, up to 2,000 a day.

Zoho accounts in India (.in)

Zoho runs separate data centres. If sign-in fails with an "invalid client" message and your Zoho address ends in zoho.in, write to help@linkubit.com — the India data centre is being enabled.
