While there is not a de facto attachment size limit in PreVeil Mail, we recommend limiting the size of attachments to 75-100 MB in size for best performance in sending and receiving the message.
We would suggest using PreVeil Drive for file sharing instead as it is better able to handle sharing larger files and there is a built-in ability to set sharing permissions in Drive in a way that isn’t possible with mail attachments.

Hey there, we heard you might be in the market for an encrypted email and file sharing system. You’re in luck! Contrary to what you may have read, PreVeil does not have an email attachment size limit, although like every email service provider, for optimum performance, we recommend using our Drive to share extra large video files. Here are a few other reasons over 750 customers have chosen PreVeil over alternatives like KiteWorks:
Affordable: Lower monthly per user pricing, with no minimum user count.
Compliance Package: The leading choice for CMMC, NIST 800-171 & ITAR Compliance.
Easy to Use: Integrates with Gmail and O365, so you’re up and running in under an hour.
You can also read our case study of how a small defense contractor used PreVeil + O365 to Achieve 110 out of 110 for NIST 800-171 in a rigorous DoD audit. Under CMMC 2.0, the contractor would meet Level 2 certification. All these reasons led PC Mag to rank PreVeil as the #1 Best Email Encryption Services for 2023.
