Hi, I am Mail Terrier. Tell me what you are looking for and I will find the right email from thousands of others. One keyword, a phrase, or a combination of rules, I can handle any task. You can set the exact folder for me to search, or I will scan your computer for all email-related files. Rest assured, I will find them all: MSG, EML, MIM, EMLX, PST, MBOX files. I don't get tired scanning gigabites of data saved on your computer. Once I am done, you can ask me to search within all the found files, or a selected destination.
Email keyword search? I can search for one word, a phrase or the most complicated rule you set. I can find an email with the words 'contact' and '2019' in the body if there are less than two other words in between, excluding those emails that contain the word 'reseller' in the subject line.
I work fast. True, it takes some time to scan all your folders, but after that I will find the necessary email in seconds. You don't have to waste your time looking through hundreds of emails to find the one you want. I also remember all your searches and save them in the history tab. I am here to save you time and effort.
What's next? I will make a list of found emails and offer you a quick preview. You can open each message with a double click. I can print out selected emails. I can save them in PDF, TEXT, TIFF, EML or MSG formats. I can export the list of results to a PDF, XLS, or DOC file with all the properties. Whatever you want to do further with the emails that I have found, I can do it for you.
Try me. I am that good. Use me for free at home for your personal searches and buy a license for commercial use in the office.

"We've been using Mail Terrier for a legal matter to search outlook email by keyword and are happy with the results. It works fast and is powerful enough for a complicated macro task. Highly recommend this app for key word search."

"I had to find all emails related to a particular case for the judge and opposing council. I would not be able to do that without Mail Terrier. Manual email search by keyword would take hours. It scanned my 1Gb PST file and produced the list of necessary emails in minutes! Thank you very much."
