Ratings and Reviews
Mobile workaround if you don't like the app
Thanks to the other reviews I've been able to get the app to work but if you don't like it you can actually use the Desktop instructions as well. Just forward the email to the address they list in their instructions and it will send you an email with a link. Click the link and it will open in Safari for you to login and view the encrypted email. You will remain logged in for a limited amount of time so you can do a few emails at once without having to login each time. The links they send do expire though, seems to be good for about 24 hours? I haven't timed it. It's been a decent workaround for me till today when I found the other reviews that explain the app. (Thanks everyone!)
Either way though, I hope Voltage will make their process a little more user friendly. Security is good, but convenience is too.
Waste of time
This is a horrible app. Once you sign in and try to download your document all you get to do it view it in the program. It doesn't download and there is no back button. So you have to close it, go back to the email, press and hold the attachment, select open in voltage, re enter your password, then enter another verification, and you finally get to select view or download document. But the joke is on you, both selections do the same thing and you cannot actually download and print anything. And with no back button, you end up wasting a lot of time
I have a secure message account set up with Wells Fargo already and needed to read a secure email on my phone. Downloaded the app, followed the instructions to press and hold the attachment and then chose “open in Voltage Mail”. I typed in my existing password, the message opened right up, and I read it and responded. I also had the option to print. No problem whatsoever.
With Family Sharing set up, up to six family members can use this app.
