How Nilkamal Fixed Email Deliverability Issues Caused by Large Attachments with cmercury
Client Overview
Nilkamal is India’s most trusted name in moulded plastic furniture and a pioneer in creating innovative, durable, and design-led solutions for homes and businesses.

Known for its commitment to quality and nationwide retail footprint, Nilkamal continues to shape modern Indian living through functionality, style, and long-term value.
The Challenges
Nilkamal regularly sends important, often confidential, communications to internal and external stakeholders. However, they were encountering a critical issue:
- Emails with large attachments such as reports, policy documents, or technical files were either being flagged as spam or not delivered at all to certain mailboxes.
- This was a serious concern, especially given the sensitive nature of some of the communication.
- They needed a reliable solution that would preserve security while ensuring high deliverability without relying on bulky attachments.
Solution:
To resolve this, cmercury implemented a secure link-based document delivery system.
Replaced Attachments with Encrypted Download Links
Instead of attaching large files to emails, we helped Nilkamal:
- Upload files to a secure, encrypted server
- Share smart download links inside emails
- Apply access controls (expiry, password protection, etc.) where needed
This dramatically reduced email size and improved inbox placement
The Results
✅ Email Deliverability Restored
Emails that previously failed due to attachment size or content filters now consistently reached inboxes.
✅ Improved Security & Compliance
Sensitive files were no longer traveling as open attachments, reducing risks and improving document access control.
✅ No More Mailbox Rejections for Large Files
The workaround eliminated the issue of delivery failure due to file size restrictions or corporate mailbox limits.
What Our Clients Say
