Customer Service Advisor

Overall experience with Omnisend is very positive. It's a great product for a fair price and does what you need very well.

Marketing Specialist

Great email marketing software which allows your marketing team to create amazing newsletters. The great advantage is that you can easily automate some tasks as welcome emails, abandoned cart, etc.

Head of Marketing

Our overall experience is super positive and we've recommended it multiple times to other businesses.

Owner/Graphic Designer

I like how the software is integrated within my eCommerce store, ease of use and the ability to save templates.

Owner / Designer

Love all the great template options Omnisend has to offer. While our decision to move our email marketing business to Omnisend was a forced one, It has turned out to be the best thing that happened.

OWNER/FOUNDER

I find it frustrating that the product picker is just not working, you have to physically copy and paste product description photo and information and paste.

Clerk

It has been a great experience thus far,  the customer service has been amazing, which is so crucial to any successful business.

Blogger/ICT expert

However, Omnisend is actually dedicated to e-commerce, and it's a great piece of software if you are running an online store for the automation capabilities that it provides.

Omnisend has been great for getting email marketing out to customers. It allows for a lot of customization which is nice, and it's also priced very well in comparison to a lot of other options.

This program is so easy to use and integrates seamlessly with Shopify. This is a huge game changer for my business as it allows us to move away from MailChimp, and on to a much more robust platform.

owner

Omnisend is so seamless. I love how easily it integrates with shopify and how easy it is to create and send email blasts with special offers.

Co-Founder

Ease of use, GREAT customer service, great templates but simple to adjust.

General Manager

The app is easy to use and give a good result. The functionalities are give an edge and good results.

For a company like mine (selling jewelry online), that is extremely important. I am always short on time, so any software that makes marketing easier for a reasonable price is attractive to me.

Director

Easy to use, clean email templates provided, also love how quick customer service is - always ready to help.

Marketing & E-commerce Manager

Not all my emails go to my customers and they complaint that our email goes to junk and before this would not happen.

Setting up Omnisend can be a little difficult, especially if this is your first time with email marketing.

Owner

This billing issue has really soured my feeling about this company. The monthly price that they show on their account page is wrong.

Clerk.io

eCommerce Manager

Clerk's integration with Magento 2 was horrific. It contained bugs, and we were unable to connect Clerk to our store at all for almost 3 weeks.

Website & Marketing Manager

Responsive technical advise and service. Overall - this is a fantastic piece of software and a fantastic support team behind them.

In the end, Clerk simply nullified our contract, arguing they are unable to fix it. By far, our most disappointing experience with any SaaS provider all these years.

Digital chief

The integration with Mailchimp and such make a real perfect solution and save a lot of time.

The setup process was smooth and flawless with the aid of the rep and the rest of the Clerk team being extremely responsive and understanding to our (often quite complex) needs and questions.

From a system integrator point of view Clerk.io is perfect. It allows to easily connect your store and start integrating recommendation sliders with quick plug-and-play solutions.

E-Commerce Manager

Hard to think of any cons. Perhaps the function to export dashboard reports.

It's hard to find a cons. There is one but it's very technical.
