Once your Zoho CRM integration is connected, you can sync your existing Zoho CRM contacts automatically into your Sinch MessageMedia account.
Contact sync
Contact sync is a one-way automatic sync of contact information from Zoho CRM to the Sinch MessageMedia platform. This means any names, phone numbers and emails in your Zoho CRM database will be securely imported into your Sinch MessageMedia account - no manual uploads required.
These contacts are clearly marked as "ZOHO CRM" in your contact list to easily distinguish them from contacts added via other sources.
Contact sync automatically triggers every 24 hours - this pulls in the latest updates from your Zoho CRM contacts list, including any changes or new entries and reflects them in your Sinch MessageMedia account.
Sinch MessageMedia sync history
Sync history is stored for 1 year. To view the sync history in Sinch MessageMedia:
- From the left-side menu, navigate to Contacts and then History.
- Click on the Syncs tab to the details of ongoing and completed syncs.
- To view detailed reports for completed syncs, click the More options (⋮) icon and click See detailed report.
The detailed sync report shows a breakdown of new contacts, updated contacts and invalid contacts.
Set up contact sync
After you've installed the SMS for Zoho CRM app, you can configure the settings to sync your Zoho CRM contacts with your Sinch MessageMedia account.

- From the left-side navigation menu, click on the Marketplace icon.

Contact sync duplicate handling
You can sync contacts from multiple supported integrations without creating duplicate records. This process keeps your contact data consistent, reduces manual cleanup and supports more accurate segmentation for multichannel messaging.
- Contacts with the same phone number will be merged during sync and tagged with a custom Source label in the Sinch MessageMedia platform under contact properties e.g. "Zoho", "Klaviyo".
- A single contact can belong to multiple source groups to enable better segmentation e.g. Contact A can be part of both "Zoho A" and "Klaviyo A" groups.
