Email attachments max out at 25 MB. Cloud storage links expire or require accounts. When you need to send a 5 GB video reel or a batch of design assets, you need a dedicated file transfer service — but not all of them treat your data equally.
Use password protection
Even with HTTPS, a leaked download link gives anyone access. Add a password that you share through a separate channel — SMS, Signal, or a quick call. SendFlow supports password-protected transfers on every plan, including free.
Set expiration dates
The longer a link stays live, the more exposure it has. Default to the shortest expiry that works for your recipient. Seven days is enough for most one-time deliveries.
Avoid public Wi-Fi for uploads
Uploading sensitive files on an unsecured network is risky. Use a VPN or wait until you are on a trusted connection. SendFlow encrypts data in transit, but endpoint security still matters.
Verify recipients
Double-check email addresses before hitting send. A typo sends your confidential files to a stranger. SendFlow lets you review recipients before sharing.
