"Impressive UI but not all companies can accept emails"

What did you like best when using this solution?

The UI for DeliverySlip is very impressive. You have visibility of what emails have been opened and which attachments have been downloaded.

Also liked the large file sending feature which allows emails with up to 5GB of attachments to be sent.

What did you dislike about using this solution?

Not all users were able to access the emails. We are a charity and tried to send secure emails to Virgin Money Giving and our payroll provider who were unable to register to view the emails. I am not sure if this was an issue with DeliverySlip or whether the issue was with the receipient.

Describe your over overall experience with DeliverySlip Secure Email Messaging. Did you find this product solved your business needs?

We are a charity who use Office 365 and require encryption to securely send emails to staff and external suppliers. We trialled DeliverySlip for 30-days but were unable to successfully get it to work for us. We had issues with 3rd parties not being able to view emails. Another issue was that the emails were being sent from DeliverySlip rather from our domain. Therefore the sent emails didn't appear in our message log.

DeliverySlip may offer the functionality to route emails through your mail server but we didnt spend enough time trying to discover if it did.
