President Religious Institutions Used the software for: 2+ years ### "ISOLATED USER" November 3, 2016 5.0 I bought a copy of Gammadyne several years ago and mail some church related mailings. I work alone and have the usual problems of someone who works alone and doesn't have other people to ask questions of. I haven't sent you money in a long time so don't expect you to have a lot of time to help me. A first problem with rating this software is what you are comparing it to. I have never seen other software to know how it relates to others. Characteristically when you are using an unusual software, everything you have to figure out is difficult. I have figured out how to send my emails (about 10,000/month) from my Access database and so it is stable at this time, which is what I expected it to do. That being said the program performs well at doing what I purchased it for. I suspect it is actually capable of a lot more, but in my isolated situation it is difficult for me to learn more how to use it. For this reason the ratings are probably more about me than the program. I have the program on a stationary computer for sending out the big email batches. What I would like to know now is if I can apply one of my 3 remaining upgrades to install it on my portable computer to send small batches "on the fly" so to speak, or if I need to buy a separate copy. I would definitely recommend the program to anyone who needed to send out batches of emails. Pros It works, meaning it allows me to send out large batches of emails at throttled rates and not get kicked off the email server for overloading their system. Cons It is a complex program and I work alone on this type matter so it was difficult for me to learn what to do. I never actually got throttling down and stable and so bought a more comprehensive email service which was more tolerant to the volume. Review Source Response from Gammadyne November 3, 2016 Benton, I'm curious why you rated Customer Support one star. You never actually mentioned any experience with our support. We give users free email support, and we answer all inquiries. To answer your question, the five activations that come with the license are not limited to any one user or machine. You do not need to buy another license. As for throttling, you simply need to enable the "Universal Domain Throttle" on the Throttles branch. RR Reyes R. Consultant Financial Services Used the software for: 2+ years ### "A robust mechanism to handle a robust campaign" November 12, 2020 5.0 In short, Gammadyne is a well-designed and reliable platform for email campaigns. Customer support is where the team excels. Most other companies seek to augment revenue with tiered support. For the novice, this software is simple to learn, and for the advanced user, it is a dangerous tool to propel your growth ambitions. Pros Gammadyne simplicity is its strength. In short, this software is a workhorse. Once you set up the individual components and set instructions as to your message and target you know have your own little sales force. Cons Two shortfalls I wish Gammadyne could handle, multiple database links and tracking included. Most other platforms have tracking as part of the package. Switched from [ActiveCampaign](https://www.capterra.com/p/79367/ActiveCampaign/) Customer service. Review Source Wendy H. Partner Human Resources Used the software for: 2+ years ### "Does what it says" February 3, 2019 4.0 Happy enough not to ever look at others. Pros Not being a web developer I found this relatively easy to understand with the help from their great support team. I imagine, however, what is greek to me is easy for anyone with more than just a rudimentary knowledge of a web page. It does what I need it to and makes my life a whole lot easier. Cons 2 difficulties I have found is 1) why I cant seem to get the tracking reports but it seems to be something to do with my email setup and so far this is a mystery to me and 2) the system seems to take close spellings of curse words to be enough to give a bad spam score. Easy enough to sort out but irritating for it to occur every time I use the program. Review Source ED Edgar D. Founder Internet Used the software for: 2+ years ### "Long time user, long time fan" January 19, 2017 5.0 I have been using Gammadyne Mailer probably for 10 years or more. It really is a full-functioned mailing program. There is a significant learning curve, but once you have set it up, it works by itself. Over the years, I have had occasion to ask Greg W. questions via email. He has been gracious with his time, and helpful with his answers -- even a decade after my purchase! \[Note: the writer may receive compensation for this review if among first 25 to send in a review. However, these are my honest opinions irrespective of whether I receive compensation.\] Pros Full function program, handling everything from sign-ups, to bounces, to sending out a weekly newsletter (in my case). Greg provides great personal support. Cons Takes some significant learning. Less than easy double-opt-in process. Review Source PG Paul G. President Hospitality Used the software for: 2+ years ### "Smart option!" December 6, 2016 5.0 If you're a DIY user, Gammadyne Mailer is an excellent choice. Sure it might be a little slower sending than a cluster of dedicated mail servers, and you need to learn the features that are important to you, but you won't feel ripped off by some service provider. Everything that I was looking for in an ESP I found Gammadyne could do. Invest in understanding how email lists work, and you'll have a very valuable tool that's going to save you a lot of money. Plus you'll keep control of your lists, manage your own sender reputation, and feel more accomplished and connected to your audience. It's the difference between hiring a promoter and learning to build loyalty on your own. It takes a little effort on your part, but the result is you understand and adjust to make your email programs much more meaningful (both internally and externally) and more likely to be read by your audience. Being hands-on with email is way better than using a service provider. The mistakes you make will teach you how to be a better communicator. Pros If you're looking for a specific feature, it's there. Cons You have to learn the mechanics of how email sending actually works instead of being hands-off and just pressing "go." Review Source IS Ian S. Director Marketing and Advertising Used the software for: 2+ years ### "Gammadyne does it all" March 19, 2019 5.0 It's an essential work-horse of our business - unlike other software we use it can seem invisible as it never causes any flaps. Just does it job day in and day out. Pros Extensive and clear help files. The fact that as well as being a complete email marketing solution as an app it also can be integrated into our own CRM. Could use it effectively from when we first got it - still learning new features or ways of using it many years later. We send around four million emails a week using it for around 50 clients. Cons I've got nothing on this - any major bugs or failings were ironed out years ago.

Information Systems Dir Publishing Used the software for: 2+ years ### "The wonders of Gammadyne" November 11, 2020 5.0 We need to send promotional emails now and then for various conferences, webinars and special offers. Gammadyne does everything we need and much more. Ease of creation of HTML emails--check. Specify Amazon simple email servers--no prob. Simple personalization--rodger. Extensive logging--check. Email job scheduling--check. Granted we use maybe 30% of the product's capabilities, but it's nice to know that click-tracking, list management and other cool features are ready for us to exploit. I am also glad to have software that we license outright, rather than having to track usage or subscription costs with other services. Pros It's pretty easy to set up while being quite flexible. For us, it's ideal for our project uses. Cons The interface design is a bit old school, but it does not affect its functionality in the least. Reason for choosing Gammadyne Mailer We started with Gammadyne Mailer many years ago. The product has continued to be updated and refined, with new features and updates coming out once or twice a year, with a good number of optional upgrades included in the very fair license price. We have yet to find a good reason to switch. Review Source AP Alvaro P. Computer Information Management Arts and Crafts Used the software for: 2+ years ### "My Gammadyne experience" March 31, 2021 5.0 Speed of sending emails is quite good. Personalisation of the emails encourages feedback from recipients. Pros Ability to test different aspects of the software functions. Ability to use variables to personalize email texts-. The ability to hook up to an Access database and update certain fields (Date email sent). Ability to segment send list via database clauses. Ability to send emails through various email servers. Cons I find the learning curve a bit steep, but I usually find the answer I am looking for in the documentation. which is clear and well structured. Reason for choosing Gammadyne Mailer When I first bought Gammadyne mailer around year 2000, there was no competing email software of any consequence. At that time I used to sell on Ebay and used Gammadyne to communicate with my clients. And since it does well what it is supposed to do I have stuck to Gammadyne. I wish Gammadyne could flag hard bounces and stop a sending session so as to keep my sending reputation at a healthy level. Review Source AI Alexander I. CEO Public Relations and Communications Used the software for: 2+ years ### "So Glad I Found Gammadyne Mailer Years Ago." November 16, 2016 5.0 I've been using Gammadyne Mailer for at least 10 years now. Although I use only a relative handful of the myriad capabilities of this amazing software, its depth of features I find astounding. It is easy-to-use for those of us with simpler needs, but capable of the most complex operations I could ever imagine for those who might require them. My analogy is that it is a Cray Supercomputer built so it can also do simple spreadsheets, word processing and browsing the web as well as handle the most complex calculations anyone could want to do. I've spent a lot of time studying its full range of abilities, only because I find it fascinating. Being a software junkie in service of making my life at work easier, I've found and used a number of great work task problem-solvers. In my opinion, I have never used any software that upgrades so meaningfully. Each upgrade has either made something better (incl. bug fixes) , added something valuable for someone, or made it easier for me to use. Last thoughts on my part, is the documentation. Their documentation is more than extensive and clear, and I have never had to call the company to find a solution to my question or problem. Even though I've never called or written the company for support I gave it 5 stars. I just assume what that will be like based on the care that has gone into the program itself. I guess I like Gammadyne Mailer :-) Alexander Irving Pros You already have my overall review that covers these points. Cons Not much to gripe about. Review Source MA Modesto A. Editor Publishing Used the software for: 2+ years ### "Great software" February 7, 2023 5.0 Great! Pros How economical it is and that it does not require periodic payments Cons It has so many gadgets that it is difficult for a non-technical person like me to understand them all. Review Source DE Doug E. Exec Director Non-Profit Organization Management Used the software for: 2+ years ### "A mailing system that just works!!" May 3, 2022 5.0 Pros Took a little time to go through it but once I caught on, was easy to use. Cons The interface could use some modernization as far as "the look" .... but it really doesnt matter much. It works as advertised and that is the point. Well done. Review Source EO Eric O. CEO/Founder Wine and Spirits Used the software for: 2+ years ### "By far, the best" December 6, 2016 5.0 I've been using Gammadyne Mailer for nearly as long as I've been operating LocalWineEvents.com over 16 years. I can honestly say that I could not have done what I've done without it. To this day, it is an absolutely essential piece of our operation. Very little trouble over the years and when I had a question, the support was (and still is) extremely helpful. I give it five stars across the board. EVO Pros Very robust. More features than you can imagine. Fully functional part of our business that has not worked as needed. Cons NONE Review Source JB Joseph B. Engineer Telecommunications Used the software for: 2+ years ### "friendly software" November 1, 2018 4.0 Excellent Pros friendly software, easy handling, Good management of information, excellent communication tool and location, allows to adapt various types of work for each case Cons Lack of storage space, slowness when there are many jobs loaded Review Source IB Ines B. Senior Software Engineer Renewables & Environment Used the software for: 2+ years ### "Gammadyne gives you back time" January 19, 2017 5.0 I have used Gammadyne Mailer for years now and it has proved a valuable friend. It has saved me hours of tedious work and always been there when I needed it. I have introduced it to other people who have again found it invaluable. Not always very easy to setup but once that's out of the way you can easily replicate and use for all your mailing needs. I wouldn't want to go without it. Pros Flexibility and easy to use once setup. Cons Setting up can be a challenge Review Source GH George H. Director Computer Software Used the software for: 2+ years ### "Gammadyne mailer" November 3, 2016 5.0 The Gammadyne mailer is an awesome bit of software in its power and scope for managing large email campaigns. The number of features can be daunting when you first use it but it is well laid out and covers pretty much everything you would want to do with an email broadcasting platform. Pros Speed and flexibility Cons Because it is so powerful there is a lot to learn about it which can make it feel complicated initially. Review Source AS Atul S. Founder,CEO and Editor-in-Chief Media Production Used the software for: 2+ years ### "Its a great software design for mass mailing. We have been using this since 2014 and its easy to use" July 6, 2017 5.0 It has helped me streamline a massive email operation and I am delighted to have this software. Its been a wonderful experience so far and I look at the various features available through the report which helps us to understand where do we have more presence and traction. Its helps to take decision as the data is readily available for us. Pros I like the design and features of tracking the emails. It's very user friendly. The features are very well designed and the overall software is easy to navigate. it gives options to connect to external database. Cons If an auto upgrade option was available with the use of license it would be wonderful. I would see that as an option available to end user. Review Source RP Richard P. CEO Media Production Used the software for: 2+ years ### "The only mailing system we'd use" November 15, 2016 5.0 Mailer is our go-to platform for sending millions of important company news communiques annually, and tracking them. Pros Lightweight, easy to understand user interface Cons I wish we could integrate it into our central mailing server rather than have to remotely control a PC it is installed on. Review Source JC Jean-François C. Webmaster Higher Education Used the software for: 2+ years ### "A reliable product" June 10, 2020 4.0 I have been using gammadyne for 10 years for sending info letters to the university community and I still love it as much. Quick, easy to use, and lots of tools to help us. Pros Easy to configure Lots of configuration options Efficient and fast online support Cons The editor for Internal HTML body needs to be improved. It is quite rudimentary. The design of the application has not really changed in years. A little makeover would be nice. Review Source OA Osvaldo A. Engineer Electrical/Electronic Manufacturing Used the software for: 2+ years ### "Simply the best!" March 31, 2017 5.0 I've been using Gammadyne Mailer for almost two decades and it is simply the best! There are so many resources available and it's good to see it in constant improvement. Pros The ease of integration with sql and different databases. G-Merge is great! Cons No cons. Review Source DN Dennis N. IT Manager Publishing Used the software for: 2+ years ### "Swiss army knife" June 10, 2020 5.0 Company was already using Gammadyne Mailer when I took over this position 15 years ago and I've never seen any reason to look elsewhere. Pros So many options and so much power! We can always find a way to do what we want with this product. Company is responsive to suggestions. Cons Can be a little daunting at first due to the impressive range of functions. Review Source NC Nicos C. IT Consultant Information Technology and Services Used the software for: 2+ years ### "A Superb powerful tool" December 15, 2016 5.0 An excellent piece of software with so many features that works better than any other marketing tool found online without any running costs at a minimal price. Pros everything Cons none Review Source CC Chris C. Marketing and Advertising Used the software for: 2+ years ### "Great Software for mass mailings" January 19, 2017 5.0 Gammadyne makes a powerful mailer at a fraction of the price of any competitor. I know I researched for weeks to find the best and this is it. Be aware this is a very configurable, and not for the weak. For example you must know your user names and passwords and gateway settings for all email accounts you intend to use. If you try to use your own domain, be aware you need to slow down delivery they call it (throttle) your emails or spam settings will kill your project. I love the merge capabilities with all major database platforms. It is a super product. Enjoy. Pros I like the configurable aspect the software gives me. Companies like mailchimp and others don't want you sending to info at addresses or sales at. Well I have alot of clients that have those kinds of emails. Gammadyne lets you do what you want. Cons Setting the throttle periods so that emails don't get junked is a learning curve. Review Source JE James E. IT Technician Farming Used the software for: 1-2 years ### "Basic functions OK, could be better." November 29, 2016 4.0 I am the network technician for our company and work with our sales and marketing team to send our mailers. The program works well for sending out bulk email without a great deal of complication. The feature I like best is that once I have set the SMTP server settings I do not have to copy or recreate them for each mailer I send, only need to adjust the mailer list itself. I find that the program works best if you create the mailer from within the program creation tools. When we have tried to import from a program such as Dreamweaver I have found the mailers do not display correctly for the recipient. Overall the product works well, but it is not for everyone. Pros Simple and basic interface, easy to use wizards. One time setup for SMTP configuration Cons Does not seem to support 3rd party software very well. Our company uses Dreamweaver for WEB design and the software does not display well. Review Source Response from Gammadyne November 30, 2016 I worked with James on the Dreamweaver problem. Dreamweaver was using an external style sheet, which is not supported with email. Fortunately, Gammadyne Mailer has a "Make Styles Inline" option that helps deal with this. JH James H. Me Non-Profit Organization Management Used the software for: 2+ years ### "Awesome product" January 19, 2017 5.0 I use the mailer for lots of different functions, usually to email to addresses stored in a database. The ability to easily use all the data stored allows me to structure individual emails as customized for each recipient as though I'd written it from scratch by hand. Pros It works. Cons Sometimes, it is a bit harder to find what I'm looking for in the documentation. BUT, the more I deal with it the better it gets.
