Payslip Distribution Shouldn't Be This Hard
If you're spending hours every month on payslip emails, making mistakes, or dreading payroll day—you're not alone. Here's what HR teams struggle with:
Hours Wasted on Manual Work
HR teams spend 4-8 hours every month manually attaching and sending payslips to each employee one by one.
Human Errors & Wrong Attachments
Manually matching PDFs to emails leads to mistakes. Wrong payslips sent to wrong employees causes compliance issues.
Disorganized PDF Management
Payslip PDFs scattered across folders with inconsistent naming makes the matching process a nightmare.
Scaling Challenges
As your company grows, manual distribution becomes unsustainable. What works for 20 employees fails at 200.
Expensive Enterprise Solutions
Enterprise HRMS with payslip features cost thousands per month—overkill for small and medium businesses.
Security Concerns
Payslips contain sensitive salary data. Using generic email tools lacks proper security and audit trails.
Sound familiar? Sheldon Sender solves all of these problems.

From 5 Hours to 10 Minutes — A Blue Dragon Story
How a Vietnamese non-profit turned a monthly ordeal into a 10-minute routine.
Blue Dragon is a Vietnamese non-profit that rescues and supports street children, trafficking victims, and vulnerable youth across Vietnam. With a dedicated team of over 200 staff spread across multiple provinces, HR operations are both critical and complex.
Before Sheldon Sender, payslip day meant five stressful hours. Now it's ten minutes and done. I genuinely cannot imagine going back.
Every month, Diep Anh dreaded payslip day. With 200+ staff across different locations, she spent more than 5 hours manually downloading each PDF from MISA, renaming files, opening Gmail, attaching the right file, typing the employee's name, and sending — one by one. "I had a checklist of 200 rows," she recalls. "If I lost my place, I had to start over from the beginning." Mistakes were inevitable. Once, a staff member in Hà Nội received a colleague's payslip by accident — a serious confidentiality breach that caused embarrassment for both HR and the organisation.
A colleague showed Diep Anh a demo during a lunch break. She downloaded the free trial that afternoon, imported her 200-row CSV, dropped in the PDF folder, and sent a test batch of 10 payslips in under 3 minutes. "I thought it would take a whole day to figure out," she says. "I was sending real payslips within an hour." Today, the monthly payslip run at Blue Dragon takes less than 10 minutes. Diep Anh opens Sheldon Sender, loads that month's CSV export from MISA, selects the folder of PDFs — and clicks Send. Every staff member receives the correct payslip, personalised with their name, every time.
