### "Mail rush to improve your engagement "

February 5, 2023

4.0

Overall experience of using this software has been really wonderful.

Pros

The software provides is the perfect combination of traditional marketing merged with digital marketing.

Cons

The UI/UX of any software plays a crucial role for a customer to make use of it very smoothly. So, I would like to recommend a little bit of more enhancement in this sector.

### "Great Product and even better customer support"

July 9, 2020

4.0

My over all experience has been very enjoyable with MailRush and their team!

Pros

MailRush has been very useful in allowing me to confidently and safely scale up my email marketing efforts. Their tools show you how fast you can scale and when you should slow down, enabling you to maximize your marketing efforts as efficiently as possible!

Cons

There have been small things missing along the way that allow for an easier user experience or more digestible data, however every time I have mentioned one of these minor issues, they have been met with almost instant action from their development team. I've been using their service for a few months and they have already added 3+ adjustments to their tools/functionality to directly address my concerns or requests. Very happy with this!

### "Useless"

March 20, 2021

1.0

This is the first poor review i've written. I'm almost 40 years old. I changed my DNS Txt and Mx records to match the instructions. Didn't work. So, I had my webhost change the DNS records for me in case it was my error. Didn't work. Customer service was useless and told me that I shouldn't bother them with questions. That they weren't the webhost. I figured I'd wait a day or two to give the DNS some time to propagate. Meanwhile, I setup templates and noticed there isn't a way to insert any type of image unless it's connected to a URL. I connected my email signature to a URL and it still did not work on this software. It works in other cold email softwares. I ask customer service if they could assist and they told me that the software is meant for cold email and that I shouldn't be asking about a signature. That I needed to simply type my name out. DNS never resolved itself after Dreamhost made the required changes. I never used the software. Software is software. Sometimes it works. Sometimes it doesn't work. If the people behind the software treat you like a pest, then what's the point of using the software? Complete waste of my time and I lost more hope in humanity.

Pros

Leaving this review is the only positive result.

Cons

The customer service is not only horrendous but rude.

Reason for choosing MailRush.io

I didn't. Trial.

### "Never using another system again..."

September 1, 2021

4.0

I should have started with this system. I would have saved alot of lost time and money.

Pros

The software is user friendly. Simple to set up, easy to execute, and the help it provided me exceeded any other programming I've used in the past. I can't wait to share this product with my colleagues.

Cons

I really haven't come across anything negative so far, no complaints at all.

Reason for choosing MailRush.io

When I searched online for suggestions, Mailrush.io seemed to have only positive feedback from the current customers.

The color scale of the software could be improved

MailRush is really good in setting up email marketing campaign and cold email marketing strategies.

### "How about 1000 Emails a month?"

May 6, 2021

5.0

Highly recommend mailrush if you're looking to do any form of cold email marketing. Don't do it using gmail or other providers.

Pros

we bought a new domain just for cold email approach and mailrush helped us warm up the domain, setup automation emails. This is the best tool to start any cold email marketing

Cons

not a con but has a learning curve to it.

### "Excellent software for cold email reach!"

November 19, 2019

4.0

There are not alot of good options for software that sends cold emails, this is a good one.

Pros

I like that when I am running an email campaign, the software will let me know if there are any spam triggers and it sends each email at a certain frequency level that you set. (Example: once every 30 seconds)

Cons

It is a little complicated to setup. The support is really good to help you get off the ground.

### "Finally!"

November 19, 2019

5.0

We use cold email outreach as a foundational platform to grow our agency. Using other programs that went through our Gsuite are not working as well as they once did. We kept losing Gmail accounts to spam filters. We knew we needed our own mail server but we are marketers not systems guys. Mailrush.io is awesome.

Pros

The software is easy to use. The onboarding process makes the program a no brainer.

Cons

The reporting dashboard is missing a some key analytics. I know they are working on them now, this is only a temporary annoyance. Considering this is the only issue it really isn't a big deal.

### "pretty good"

November 14, 2019

4.0

Pretty good see above

Pros

Easy to use once you understand the options. Responsive customer support. Pay as you go billing.

Cons

I needed help to figure stuff out in the beginning. Slow and difficult contact downloads when trying to download large contact lists. Would like premade templates that can be clicked and "filled out" rather than HTML coding myself.

Reason for choosing MailRush.io

Prospect emailing is allowed without having to go through extra steps
