Domain Sync between Zoho Services and Zoho One
When you verify a domain's email authentication records (such as DKIM and SPF) or add and verify a sender email in Zoho One, the domain gets synced across all the applications associated with your Zoho One organization. Once the domain and email are verified in Zoho One, the system automatically skips additional verification steps (like OTP verification and domain record validation) in individual apps, saving you time and reducing repetitive tasks.
Domain verification data can sync in two directions:
- Zoho One → the integrated Zoho services: Both domain records (DKIM, TXT) and sender email verifications are synced. This also allows individual apps to skip verification steps if the domain is already verified in Zoho One.
- Zoho services → Zoho One: Only DKIM record verifications are synced and further shared with other integrated apps in your bundle. However, the verification of a sender email inside a Zoho app will not reflect in Zoho One.
Zoho services don't receive domain data instantly when it's added in Zoho One. There are some cases when they have to pull it:
- Re-adding a domain in a service: If you delete a domain in a Zoho service and later re-add it, the service will pull the stored records from Zoho One. As the data exists in Zoho One already, the domain is auto-verified in the service without having to redo the verification.
- When services are migrated into Zoho One: If an app is migrated into your Zoho One bundle, any verified domains already present in that service will be automatically fetched into Zoho One as part of the unification. Only verified domains are included in this migration.
However, sender email verification syncs only one way, i.e., from Zoho One to services. It's not synced back to Zoho One if verified directly from a service.
Domain - Email coupling
The relationship between a domain and a sender email varies across Zoho apps. Some apps treat the email and domain as coupled (linked/dependent), while others treat them as uncoupled (independent).
- Coupled (Linked)
- Changes to the domain and email are interdependent and linked.
- Example: With Zoho Campaigns, you can delete a domain only if there’s no sender email associated with it. If a sender email is linked to the domain, you must delete the sender email first.
- Uncoupled (Independent)
- The domain and email are independent. You can modify or delete one of them without impacting the other.
- Example: With Zoho Analytics, you can use any email as the sender email, and it won’t affect the domain settings. They are treated separately.
App | Domain - Email Coupled (or) Uncoupled | Note |
Zoho CRM | Uncoupled | Domain will be synced from Zoho One to CRM only if there's any user email or organization email associated with that domain. Sender email configured in Zoho One can't be used as sender email in CRM, because CRM only allows organization email or user email to be used as a sender email there. |
Zoho Forms | Uncoupled | Sender email doesn’t sync from Zoho One. This is because another user's email is only allowed to be used as the sender email in Forms. |
Zoho Assist | Uncoupled | Only one sender email is allowed. If none is set in Assist already, the email verified from Zoho One gets synced. If a sender email is already set in Assist, it won't be overridden. |
Zoho Analytics | Uncoupled | Use any email as the sender; Sender email already verified in Zoho One won't require verification again when it's used in Analytics. |
Zoho Projects | Coupled | Only one domain and email can be used. No new domain or email from Zoho One will get synced. Both sender email and domain records will be synced to Projects when the domain is already verified in Zoho One. |
Zoho Campaigns | Coupled | Sender email is a prerequisite for domain addition. Both domain and sender email must be verified in Zoho One to sync. Sender email will sync only if it is verified. |
Zoho Marketing Automation | Coupled | Same as Campaigns; both domain and sender email must be verified. |
