Blocked Email
We are a Zoho One subscriber and use Yahoo as our MX provider.
A few times each year, for the past four years, CRM blocks one or more of my Zoho One users from receiving internal email from CRM. This includes "@mentions" in all modules, and emails from ' notifications@zohocrm.com'.
When I talk to Zoho Support, the first reaction is "we don't see a block." When I insist, they dig further and find the block. Correctly, they require an email request to unblock from superadmin and the affected user.
It is almost certainly the case that my users are not proactively unsubscribing from internal zoho notification emails...they rely on those notifications to do their work.
Is there anything I can do within Zoho to ameliorate this problem? Can I have "notification" email come from our fully authenticated domain?
Here's what's probably happening...
Yahoo Mail has notoriously aggressive spam filters, and automated CRM notifications are a common trigger, even when properly authenticated (which yours are).
Why Yahoo Auto-Flags CRM Emails:
Bulk sending patterns - Even though it's one email, it comes from a bulk sending infrastructure (notifications.zohocrm.com)
"Re:" subject line - Yahoo may see this as suspicious since it's an automated "Re:" without a clear conversation thread
High HTML complexity - CRM notifications often have heavy HTML/CSS (I see this email was 80KB - quite large)
Generic "from" address - not********@zohocrm.com looks impersonal
Automation headers - The email literally says xcrm-src: Automation in the headers
What You Can Do:
Immediate fixes:
Use a custom domain for sending - Instead of notifications.zohocrm.com, send from @yourdomain.com with a friendlier "from" name
Simplify email content - That 80KB email is huge. Strip down unnecessary formatting
Improve subject lines - Avoid "Re:" in automated emails. Use clear, direct subjects like "Action Required: Sign Deal Documents"
Long-term solutions:
4. Separate internal/external sending - Use different email configurations for employee notifications vs customer emails
5. Whitelist request - Have employees add your CRM notification address to their contacts/safe senders
6. Reduce email volume - Consolidate notifications into digests where possible
In Zoho CRM:
Check Settings → Email → Delivery Settings
Consider using a dedicated sending domain with better reputation
Review your email templates to reduce size/complexity
Even with perfect authentication, Yahoo's filters are algorithmic and can be overly aggressive with automated business emails.

Hi folks, Usually when you send emails to your users, the display name defaults as your From email address. Most often, you would like to set a custom display name to represent your organization or the context of the email. You can mask or customize the display name (From Address) using Deluge script as long as the From email address has been verified. This would be very useful to you if you want to send bulk emails to a large audience. Let's say you have a Student Registration form for your danceImporting Data to update and not add
