YAMM does what it says it does! I just needed help resolving a small subsciption issue and got pretty much immediate help from their customer service.
I needed a refund because one of our team members left. They were very responsive!
I have been designated by high school classmates to send out mass emails for our class reunions. Mind you, we graduated decades ago. I initially set up YAMM with my personal email but quickly realized this was not the right way to go. I needed to send the mass reunion emails out from out the reunion email account. I put in a request to YAMM to please transfer my YAMM subscription over to the class reunion account. YAMM responded quickly and fixed it for me.
Excellent tool - super support - great value for money on a team plan :)
This plugin is very useful and also allows tracking of whether recipients have opened the email. However, one area for improvement could be that test emails sent to oneself also count toward the quota. Perhaps a feature could be developed to preview the email content without using up the sending limit. Also, if the free quota can slightly rase to 30, it would be really helpful.
Quick reply and good follow up. Very happy with the service.
Been using Yamm for a very long time. Fantastic product. Last year, I used it briefly for a client...I have since stopped working with said Client. I reached out to YAMM as I couldnt remember why the charge occured. They answered incredibly timely (within an hour) and didn't push back at all on my request for a refund. Great tool and great CS.
I was not able to find what I needed through search and even though I am currently in demo mode YAMM answered my questions within a day even though it is a weekend.
For the sake of clarity, I have only just started to use YAMM. However, having tried several mailing services over the last 3 years, I had all but given up on mail campaigns. I don't send huge quantities of bulk emails, usually no more than two per week, each with less than 100 addresses. You'd have thought most systems would handle this adequately, but they don't. They are filled with complexities, challenging to use mail formatting tools, people end up unsubscribed, and I have no way to resubscribe them, just painful complexity. Then I found YAMM. I created a spreadsheet in minutes, formatted an email using Google Layout and sent it to 90 addresses easily and quickly. I now have clear reporting of who is opening and clicking. It's such a great application and at $60 per year.... Wow! Great work YAMM
Every time I use this tool--which is multiple times a week--and any time I've had to reach out to their support team--which has only been a couple of times in multiple years--I'm thrilled with the result. YAMM is a fantastic tool with practical features that make me more effecient.
Since I discovered the YAMM software many years ago, I've loved it! It is easy to use and saves me so much time. Now I have a new reason to love the company. I was billed for a subscription for an old email address. The customer service rep. replied within a couple of hours and issued a refund. Thank you for your quick response!
I had bad experience with many services providers when you expect for support, but here I was surprised about quick customer care by Yammi.
I've been a YAMM client for several years and have always had a prompt and helpful customer service experience with any questions or issues. A+
Absolute scum, another roach motel subscription service that once you enter, you cannot exit. They've been billing me for years. Don't use!
Thristan Luna provided outstanding customer support! The process was smooth, easy to understand, and her explanations were clear and helpful. She went above and beyond to assist, making the experience hassle-free. Truly excellent service!
I received accurate guidance and support very shortly after sending my request.
