Verify the emails in your Zoho CRM contacts and leads

The workflow

1. In Zoho CRM go to Setup > Data Administration > Export and click Start an Export. Pick the module (Contacts or Leads), filter by a custom view if you only want part, choose All Fields or Choose Fields with Email and the record ID included, and pick CSV. When Export History shows Completed, hover and click Download. You need the Export permission; one CSV holds up to 200,000 records and the link lasts seven days.
2. Upload the CSV on the verify page, signed in; the first 100 checks are free. The email column is found by its header or contents and every other column is kept.
3. When the job finishes, download the valid, risky and invalid files. Each keeps all of your original columns.
4. Add a single-line custom field named Email Status to the module (Setup > Customization > Modules and Fields) if you do not have one.
5. Go to Setup > Data Administration > Import, choose the module and your file, and select to update existing records. Pick the Record Id (a field you can rely on as unique) as the match field and map it to the ID column.
6. Tick the option to skip updating empty values so blank cells do not wipe data, map the result column to Email Status, and run a small file before the full ones. Then create a custom view where Email Status is not invalid for campaigns.

Columns to map

• Record Id as the match field, mapped to the ID column in your file.
• Email, left as is, so the address you verified is the one on the record.
• Email Status, your new field, taking the result from the SimpleVerifier file. Mandatory fields missing from the file cause those rows to be skipped.

What to do with risky and catch-all results

Keep risky contacts in the CRM and mark Email Status as risky. Filter them out of Zoho Campaigns and mass emails, but leave them in call lists and sales sequences. A catch-all domain is often a real company, so only move to delete on invalid.

What people use it for

• Check Leads that arrived from web forms and Zoho Forms before a mass email.
• Give sales a clean Contacts view before a quarterly outbound push.
• Audit database quality before you migrate to or from another CRM.

Using the result

Each address comes back valid (the mail server confirmed the mailbox), risky (delivery could not be confirmed: a catch-all domain, a role address such as info@, or a provider that hides mailbox status) or invalid (it will bounce, or it is a throwaway address).

Full endpoint reference, error codes and an OpenAPI file are in the API docs. For lists of thousands of addresses, upload a CSV on the verify page instead.

Common questions

Which plans include API access for Zoho CRM?

API access comes with Pro, Business and Agency, listed on the pricing page; Starter covers CSV verification only. A key on a plan without API access gets a 402 that says so. Each key can make 120 calls a minute.

Can I undo a Zoho import?

Zoho lets you undo added records but not updates to existing ones. Keep the original export, and test with a few rows first.

Does SimpleVerifier work in Zoho Flow or Deluge?

We do not ship a Zoho Flow app or a Deluge function. If you build one, it would call the SimpleVerifier API with your own key; for a whole database the CSV route above is simpler.
