MailRaider Pro Saves the Day

Recently migrated from the MS world to Google G Suite. While we were still using Outlook, plenty of people attached emails within emails or exported emails in .msg and .eml formats. Gmail and G Suite can’t open these formats without the use of Chrome extensions which present security challenges. MailRaider Pro handles these files easily and gets the job done every time.

hallelua MailRaider Pro

this review is from someone who is not tech savvy.
! i had a “professional” transfer my PC over to my new Mac desk top. There were several files that transferred from my home screen that I was not able to open on my mac bc they were .msg form. I called Apple Care and he was able to google my problem and he found MailRaider App and said maybe that would help. I looked into the App, saw 2 versions and not knowing exactly what I needed, I bought the pro version, just a dollar more. i tried agian to open these files and it still didn’t work so I read reviews under the MailRaider App, that is where i found a review that told me i needed to right click on the file I want to view. i went back to the files, right clicked on the ones I wanted to read, then clicked on “open with” which showed a pop up with one of the options being MailReader pro, i clicked on that and voila there was the file i wasn’t able to read for the past 6 months since I’ve had everything transfered over. yeah! Thanks you to Apple Care for helping me find this app, thank you to the person who told me I must right click on the item i wanted to read and finally thank you to mailRaider for creating this App. not sure if i did overkill by downloading the Pro version, but for a dollar difference…who cares!

It doesn't show the images IN the email.

My .MSG emails have a lot of pictures and text together.
This program show all the images in a separate area called "Attachments". It doesn't show the text and images together. So it's impossible to figure out what they are talking about. (I have 10 images in the attachment area, but not in the message)

Unfortunately, this is not useful to me.

Developer Response ,

I'm sorry to hear that you've been having trouble with MailRaider - it is true that for some emails the images don't show in line. In these circumstances, it would be helpful if you could contact us with a sample so that we can fix it in future versions. Please email support@45rpmsoftware and we'll do our best to resolve this problem.
