Executive Technologist Information Technology and Services Used the software for: 2+ years ### "Ideal for keeping focused and staying "on top" of everything" June 20, 2024 5.0 I have been using Leanmail for more than 12 years. Anyone who must process a significant volume of emails daily really needs to consider this tool to keep it all under control. Pros Helps organize email in a fashion to optimize productivity. Cons Doesn't work with Microsoft's latest version (because Microsoft's new "web based" version doesn't offer plug-in features the same as in the past.) Review Source Response from LeanMail June 26, 2024 Mitch, it has been and continues to be an honor and a pleasure to serve you. Thank you for your review and for being a loyal advocate of LeanMail. Best regards, Michael SS Sade S. Resident District Manager Food & Beverages Used the software for: Less than 6 months ### "Using LeanMail" June 3, 2025 5.0 I'm still getting used to it so it's taking a bit, but I know I can't go back to regular outlook. I will continue at it until it becomes second nature. Pros Ability to organize my email and set reminders for emails I need to follow up on. I really like being a bit to set dates for follow up as I usually forget getting back to important emails. Cons It's time consuming until it becomes a habit. It's not a habit yet but it's slowly getting there and now I'm a bit stressed when I don't get the opportunity to clean my inbox. Review Source Response from LeanMail June 4, 2025 Thank you so much for the perfect review, Sade! Try to remember NOT to clean your inbox, but to follow the Prioritize and Plan procedure each time you enter Outlook - so it will never get messy :-) Best regards, Michael Hoffman TL Tonino L. Operational Excellence & Strategy manager Automotive Used the software for: Less than 6 months ### "LeanMail experience 2022" March 23, 2022 4.0 it is fine Pros at the moment the email organization based on my priority Cons at the moment nothing because i need to use it more intensive... i dont know yet all the functionality Review Source Response from LeanMail March 24, 2022 Thank you for your review Tonino.

You also have access to free eLearning, and of course you can get free coaching any time by contacting us. JT Jonas T. Pharmacovigilance and Medical Information Manager Pharmaceuticals Used the software for: Less than 6 months ### "LeanMail - keeping me sorted" September 16, 2024 5.0 great courses and good with reminder emails to remember all the features the software has built in. LeanMail team is helping you through the initial problems to adapt to a new way of working. Pros Oversight of my current and planned tasks. Easy to find emails when looking for. Easy process to always go through the emails, knowing what to prioritize. Cons not so efficient to use "conversation view" when wanting to delete several emails in a thread. Not possible to use lean for coming outlook versions? Review Source Response from LeanMail September 25, 2024 Dear Jonas, Thank you so much for your excellent review. The new Outlook has not opened up certain features for us to develop our dashboard views, but when they do, we'll be there! Thank you again! GM Guillaume M. Business Excellence Manager Pharmaceuticals Used the software for: Less than 6 months ### "Guillaume's Leanmail review" August 28, 2024 4.0 Overall good. I'm happy with using LeanMail. Pros Possibility to create task in the future with a deadline in order to focus on the right things at the right time. Cons It slows down outlook from time to time and experienced some crash. Regularly outlook is blocking the add-on. Seems to create issues with the search functionality of outlook from the inbox. Review Source Response from LeanMail September 25, 2024 Very sorry for the delayed response, Guillaume. I completely understand your frustration, but hopefully it has worked itself out. This rarely happens, and usually only when someone has moved tens of thousands of emails. Please write to me personally if the problem has not cleared up. Best regards, Michael AB Andreas B. Technical Account Manager Information Technology and Services Used the software for: 2+ years ### "A great tool for organizing your email" June 17, 2024 4.0 Overall when sorting out a few kinks and figuring out how to use LeanMail so that it behaves like I want it, it is a great product and one I highly recommend. Pros Very easy to use and getting into. LeanMail helps me to organize my emails and keeps my inbox clean. It has completely changed the way I use Outlook and keeps down my stress levels. Cons If you use the same subject when you email several different customers, it will set the response emails with all categories. I would like the ability to remove certain columns like "mentions" for example, because it is not optimized for smal laptop screens. Review Source Response from LeanMail June 25, 2024 Thank you so much for your review of LeanMail, Andreas. It's a great pleasure serving you. I apologize for the features that you would like to change, but they are hard-wired into Outlook by Microsoft, and for that reason we can not change them. Best regards, Michael JH Joel H. District Manager Food & Beverages Used the software for: 1-2 years ### "Great Value" June 20, 2024 5.0 Can't live without it! My productivity at work as been so much better since I've had LeanMail. Pros Keeps me organized and I am able to better manage my time in the field. Cons I experienced an issue with the software. Review Source Response from LeanMail June 27, 2024 Hi Joel, Thank you very much for the stellar review. I'm very pleased to hear that your productivity has increased since you've been using LeanMail. Let us know any time you need any extra help and we'll be happy to provide that. Best regards, Michael SF Susanne F. Sales and Customer Engagement Coordinator Pharmaceuticals Used the software for: 2+ years ### "Can't live with out LearnMail" May 11, 2022 5.0 Again this software makes my work live easier - I am in control of my mail not the other way around. Pros This software gives me an easy overview of all me mail and it is very easy to use after getting a very good introduction from the company. I always know what are in my mailbox and what to focus on today. I can imagine not having LeanMail - then I will for sure loose my overview of all my tasks. And easily forget something. Cons I don't know - I should be when I from time to time loose it do to some IT issue - then I am lost :-) Review Source Response from LeanMail May 13, 2022 Thank you so much for your great review, Susanne. It's always nice to hear that we are having a positive impact. Eric D. Director Computer Software Used the software for: I used a free trial ### "Life changing management of emails" April 29, 2022 5.0 Great live support and training from real experienced people. I have changed my email management following a proven successful process. The installation, training and use of the options are so beneficial, I would recommend to everyone to adopt this change. Pros This tool integrated my email system very smoothly to revolutionise my email management. I now so confident that I will not miss any actions to take, loose any step. It is the best way to manage my emails. The training that is included is really easy to follow from a team that supports me every step of the way. Cons No complaints, like any change, it took some transformation (dropping bad habits mostly) and take a leap of faith that paid off in spades. Review Source Response from LeanMail May 2, 2022 Thank you for your fine review Eric. The team is cheering you on! Bas V. Sales Director Information Technology and Services Used the software for: Less than 6 months ### "LeanMail review" March 28, 2022 4.0 Pros The LeanMail software let's you organize your inbox where you thought it was under control. You will not slip a promise or forget a reply ever again. Cons It grabs you by the throat, you can never actually say "I missed your email" Review Source Response from LeanMail March 30, 2022 Hi Bas, I love the line that "it grabs you by the throat". Hopefully that's a good thing. LOL! DB David B. CEO Professional Training & Coaching Used the software for: 2+ years ### "Très utile" March 7, 2022 4.0 Notre problème résidait dans le fait que l'arrivée des mails perturbait les actions de la journée. Avec Lean Mail une lecture rapide chaque heure permet de déterminer l'urgence et l'importance de la demande des ails reçus, de les prioriser et les échéancer en peu de temps puis de se concentrer à nouveau sur les taches à accomplir. Pros Lean Mail permet de séquencer l'activité de la journée. Le tri des mails est réalisé en quelques minutes. Il reste alors à traiter des mails programmés sur la journée. Cons C'est parfait ne changez rien ! Review Source Response from LeanMail March 8, 2022 Thanks very much for the excellent review David. Much appreciated. FF Fernando F. sales Utilities Used the software for: 2+ years ### "it is a good tool for mail control" August 11, 2022 5.0 since years ago i have good control of mails and no one is missing Pros the control of mails, really it is perfect Cons really all software of leanmail is very helpful Reason for choosing LeanMail by Michael, Review Source Response from LeanMail August 16, 2022 Muchísimas gracias, Fernando! BM Birthe M. Director Insurance Used the software for: 6-12 months ### "LeanMail works" January 21, 2022 4.0 Great tool, great people at LeanMail Pros Great tool for efficient execution of inbox and planning Cons Lack of GDPR security policies (deletion rules) Review Source Response from LeanMail January 24, 2022 Thank you so much for your excellent review Birthe. I'm glad you brought up GDPR because a number of our customers aren't aware that we actually do provide these security policies, albeit on a per-customer basis. The reason is that every customer has different requirements. Please let us know if at some point you would like to discuss which customizations you would like. Again, thank you very much for your review. CS Christian S. Trainee Retail Used the software for: I used a free trial ### "Workflow speed increase!" December 16, 2021 5.0 excellent, fast and productive! Pros Not only does it file and sort my mail nicely. It increases the speed of my workflow. The amount of time saved, reading through email agian and agian, and not sorting and planning is now fast and effective with minimum timeusage! Cons The learning curve is somewhat high, and the features are many. But i have now used it for a few weeks, and i dont see my self going back! Review Source Response from LeanMail December 17, 2021 Christian, Thank you so much for your feedback. Glad to hear that you are getting real value from LeanMail. LB Lyndon B. CEO Information Technology and Services Used the software for: Less than 6 months ### "I don't need my 45 inbox rules anymore" May 5, 2022 5.0 Straight forward, immediate benefits Pros It was simple to get my head around and start using immediately. Cons 3 days of what the heck is going on (post inbox rules syndrome) Review Source Response from LeanMail May 6, 2022 Thank you Lyndon! You are a star! JS Jesper S. CTO Information Services Used the software for: 2+ years ### "Great time-saver" February 21, 2022 5.0 It's a game-changer, really. Once you get the hang of it you'll never go back to what you did before. And if you stumble along the way, friendly LeanMail staff will follow up and help you get back on track. Getting started and understanding the process will take a little effort on your part, but once you've adapted to it you'll be amazed so few people have picked up on it. In 10 years this is how all managers will be managing their written communications. Pros Seamlessly integrates into Microsoft Outlook and enhances it by putting existing features front-and-center, while also adding new valuable features to boost email productivity. Cons Learning curve is a bit steep. But hang on - it's well worth it in the end! Review Source Response from LeanMail February 23, 2022 Dear Jesper, thank you very much for the positive, frank review. You have been an important contributor to our success for over a decade and a half. Thank you again for all your feedback, and keep it comin'! TA Tony A. Principal Information Technology and Services Used the software for: 2+ years ### "I know what I need to take care of" March 7, 2022 5.0 Leanmail has been a great tool for many years now. I am able to manage my mailbox and keep it very clean so that I don't forget items that need to be taken care and prioritize my day. Seeing only 10-20 total emails throughout the day in my total inbox is such a stress reliever. Pros Quick Prioritization and setting Next Action elements Cons When working on Today's mail, it would be great to have another priority or two. For example, I have a couple of high priority items, and a few normal items. I will take an action step but then I need to wait on a response, so I don't want to move it to the next day, because I want to reach out to the person I am waiting on a response from again before the end of the business day. So, a hack I do is add an "x" in the My Priority feild, so that it pushes that email to the bottom, so I don't continually see it in my list of emails that I have not taken the next step for that day. Hopefully, I am being clear. Review Source Response from LeanMail March 14, 2022 Thank you for great the review, Tony. Remember that you can use the "P" priority (P for Personal) as a third option. TM Tim M. Professor of Computer Science Higher Education Used the software for: 2+ years ### "Leanmail has reduced the amount of time I spent an email each day" January 24, 2022 5.0 The Leanmail process, particularly email prioritisation and planning, have helped me to focus when reading & responding to email. Instead of continually going over 100 emails in my inbox to find the next one I respond to, I only touch most emails once. I estimate this has saved me 30-60 mins each day. The Leanmail tool is useful to help implement the process, but it is really the process that is important. The Leanmail training, particularly the follow-up sessions, we really helpful to establishing this as a habit. Pros Email prioritising Email planning Archiving Cons The Leanmail tool is not available on Android. It would be nice to be able to do the initial prioritising on my smartphone. Review Source Response from LeanMail January 24, 2022 Thanks very much for the review Tim. I really appreaciate your kind words, which will hopefully help people find LeanMail too. RA Robert A. Owner Computer Software Used the software for: 1-2 years ### "Organize & Stay on Track" April 26, 2023 5.0 Pros LeanMail provides the tools and a working framework to organize and manage the email you get daily. It hides the email you don't need to work on that day to declutter your inbox. Following the process framework learned in training, LeanMail allows me to quickly review, prioritize, and schedule the hundreds of emails I receive daily. Cons The setup is easy, but it is an Outlook addon, and customizing it requires some knowledge of Outlook. Additionally, there is no Android app or iPad dedicated app. There is an iPhone app. Review Source Response from LeanMail April 27, 2023 Dear Robert, I wanted to send a quick note to say thank you for the recommendation. Your support means a lot to us, and we truly appreciate your confidence in our abilities. CK Casper K. Solution sales Specialist Business Supplies and Equipment Used the software for: Less than 6 months ### "Take control of your outlook" December 16, 2021 5.0 Planning my day to day work, scheduling my emails for when i need to get action on them. Having the Next Action solves some of the time spend reading the emails aswell. At most i look at the same email twice before it has been archived. Pros When we first got introduced to LeanMail, we only had the first module with archiving. This was a somewhat nice feature, it made everything easy to see and find. But i was also introduced to automatic category assignment which didn't help out that much. With module two, where we had Prioritize and Plan... Waow, instantly i got more time in my everyday, the hole process of managing my mailbox, i thought i had a decent grasp of what was good, but this system blew it away, before i was spending 3-4 hours on my mail everyday, with prioritize and planning i'm spending around 1-2 hours. This has been a great tool for getting back some of the lost time i'm using on outlook so i can be more productive in my everyday, even this review is only possible to write for me, because i was done with my inbox and everything was planned for another day. Cons You're forced to use a new way of managing your mailbox. This was the hardest to overcome, i'm a folders guy (or used to be) and like the way it was working, so being forced by a sales person to use their product when i had a great workflow was something i had to work on. Review Source Response from LeanMail December 17, 2021 Hey Casper, I really appreciate the effort you made in writing such a comprehensive, frank and kind review. RS Roy S. President Writing and Editing Used the software for: 2+ years ### "Favorite solution for archiving & storage of critical emails" March 3, 2022 5.0 It enables me to avoid duplication of effort. Each year I send out thousands of emails with complex content, but much of their content is some version of a message I've composed in the past. The archiving feature enables me to organize my email content going back years, and I can easily retrieve the most recent version of the specific content I need to use today. — I use this feature virtually every day to avoid duplicating effort. Pros With the archiving feature, my emails are never "lost" or difficult to retrieve. It's safe & reliable. Cons Can't think of anything. The software always performs exactly as advertised and is useful every day. Review Source Response from LeanMail March 4, 2022 Thank you for this stellar review Roy. MB Marek B. Regional Quality & Lean Manager, Europe Packaging and Containers Used the software for: Less than 6 months ### "Happy and on-track user" January 28, 2022 5.0 Pros I like the most simple planning based on - simple too - prioritizing tool. It helps me the most in keeping things to be done and not forgotten, and - most important - very easy to be processed. Cons Frankly speaking, as it is add-in to MS Outlook, I'm afraid that if I change my job, I will loose my license, and will have to convince new employer for new one ;) Review Source Response from LeanMail January 31, 2022 Thank you very much for your review Marek. I'm happy that LeanMail is making a positive impact for you! DC Dan C. Global Continuous Improvement Manager Chemicals Used the software for: 6-12 months ### "LeanMail Feedback" January 18, 2022 5.0 Superior customer support, tips, and advice! Easy to implement, training and adoption went well, and I have had periodic discussions and feedback from Michael Hoffman. I am working to promote it with my colleagues, but getting them to devote the time has been a challenge. Pros I appreciate the ability to prioritize and level load my emails out. Due to this feature, I am able to end work days feeling like I did what HAD to be done before logging off. Cons I haven't embraced the archiving feature yet, but intend to give it a try. Nothin I don't like Review Source Response from LeanMail January 19, 2022 Thank you for your excellent review, Dan. I'm really looking forward to continuing our collaboration and I am inspired by how readily your teams are adopting the LeanMail methodology. LB László B. Global Head of Customer Experience Health, Wellness and Fitness Used the software for: 2+ years ### "I can not live without Leanmail anymore" March 24, 2023 4.0 I can not work without it! Pros Having simple rules: if I can answer within 5 seconds - do it. If I need more time to process - decide: important or not important. Then when it's categorized (important) - add the next action and the topic and a date. I can manage and prioritize my emails easy! Cons If I have a trouble with a licence and it disappears :) - but this is solved by Customer Service fast and this is very rare. Review Source Response from LeanMail March 27, 2023 Thank you very much for your great review. I think you've done a great job describing just how easy LeanMail is. :-) MH Mulat H. Head of HR Pharmaceuticals Used the software for: 2+ years ### "Focus" August 29, 2022 5.0 It provides better overview on my daily priorities, so I can focus on my real tasks (such talking to people :-)) Pros E-mail and tasks Management. It helps me to structure my e-mail inbox, easy archiving and structure of tasks Cons Small part, that the system does not show calendar when prioritizing tasks (you have to type in a date) Review Source Response from LeanMail September 2, 2022 Thank you so much for your review, Mulat. I'm happy that LeanMail is making such a positive impact for you.
