Hi A-E,
I can see why this would be concerning when delivery isn’t consistent. As a workaround, try sending the pay slips in smaller batches rather than selecting everyone at once. It’s also worth checking that each employee has the correct email address and pay slip delivery setting, then asking them to check their junk or spam folder. Before resending, go to Payroll > Print/Email Pay Slips, select the correct pay period, then open Advanced Filters and untick Unprinted or Unsent Pay Slips Only. You can then resend the missing ones and check Sent Emails for their delivery status. These guides may help:
If this keeps happening, make sure to reach out to our support team via Contact Us page for them to check what's happening.
Cheers,
Doreen
