Anonymous Survey Email Distribution
Excel → unique links → bulk email, without tying answers to identity.

What they needed
An existing dashboard/scanner portal needed one module: upload employee Excel data, mint unique encrypted survey links, send at scale, and track completion without linking a person to their answers. IT also needed SPF/DKIM/DMARC guidance.
What I delivered
- Excel column mapping for email, stream, function, department, location, age, gender
- Unique encrypted URL generation against the existing scanner link
- SendGrid / AWS SES path for 1,000+ sends
- Completion tracking with anonymity constraints; DNS/auth records for deliverability
- Security architecture review notes for the client’s IT team
Why it helped
Surveys go out in bulk with trackable completion, while answer anonymity and mailbox deliverability stay first-class.
