Aid4Mail is faster and more secure than cloud-based migration solutions

Migrating your mail to Office 365? Moving from Outlook, Thunderbird, Eudora? Or perhaps from archived EML, PST or Mbox files?

Aid4Mail will be faster and more secure than a cloud-based solution if you’re moving from on-premise to the cloud.

Here’s why:

  • Data security assured: With an on-premise migration tool like Aid4Mail, you don’t have to worry about who has access to your email. Unlike cloud services, and some on-premise tools, we send no data back to our servers. So you can rest easy knowing you’re in complete control of your data.
  • Faster conversion: When you use Aid4Mail, the mail conversion is done locally and then uploaded. With cloud vendors, your mail is uploaded, converted, then has to be transferred to your new email provider. With Aid4Mail, you save a whole step.
  • Accurate results: Aid4Mail is so accurate and reliable, even digital forensics professionals use it to convert email. So when you choose Aid4Mail for your migration, you know you’re going to get a great result.

“Aid4Mail is a spectacular product. I don't think people realize how hard it is to reliably convert email from one format to another, and then do it at scale the way you do. It really is quite an accomplishment.”
– Matt Coan, Sonian          [ Read our Sonian Case Study ]
