Once I learned the software, ConvertKit became a pleasure to use. The feedback we got from our subscribers was fantastic.

Founder, Course Creator

Great experience overall. My sales are better because I can be super specific with who I'm emailing, based on their interests (links they've clicked, courses they're already enrolled in, etc.).

Blogger

The metrics feature is amazing - you always know if your emails were received well from your subscribers. I love the ability to have a series, to test your headlines, and to understand the analytics.

Writer 

Customer service is also amazing. They reply super fast and are eager to please.

Owner

It gets really frustrating trying to troubleshoot all of the scenarios and errors that can happen. Overly complex to deal with.

President

Terrible follow up a waste of time and a malfunctioning system. I was never alerted that a.

I am a huge fan of Convertkit. I think it is the best email marketing tool currently available.

Author

Great deliverability, great customer service, has all the features I want.

The platform is easy to navigate which makes it beginner friendly. The user has the ability to send emails to people knowing they are the exact ones to receive it through the use of tags and segments.

I love the ease of use, it allows me to deliver a message to my audience without having a complicated system.

It also provides facilities to create visually appealing opt-in forms that are easy to integrate with tools like Elementor and others and can be beneficial for lead generation.

Founder

My favorite thing about convertkit are the easy to setup email automations. The visual builder makes it intuitive and clean.

I've repeated myself over the course of 5 days now and still can't get anyone to understand the issue. Let alone apologize for a mistake that looks like a glitch in their system.

Convertkit has incredible customer service, a unique easy to understand interface (the visual builder) and is very good value for money.

It is easy to use and set up. I love the email editor.

I've asked for a manager and the people on the chat just ignore that. There's no phone number to call.

Web Developer, Internet Marketer, and SEO Consultant

We use the platform for blog subscriptions, online courses, and other special email series. It works well, it's easy to navigate, and easy to implement on web pages.

It's really easy to create email campaigns and to use tags to create workflows for automation. For one client, their whole membership site is ran by convertkit integration.

Totally happy with its use as it made my work very easy to switch from one mail to another also with amazing features of Facebook and WhatsApp makes our day amazing.

The ease and functionality is out of the roof, specially that ui design its mesmerizing when i installed it first i was like in love with the ui and functions available.

Also sometimes it bugs out with my outlook email accounts, I will repeatedly get error warnings, but I am still able to receive and send emails with the account, not sure what that's about.

It is great for email offering smart unified inbox and easy to navigate. It is also a quick and responsive app.

Good price for the product. Had a few questions and were pleased with the support.

Mailbird can truly be an all in one productivity solution for you and your business. It integrates email, Evernote, Todoist, and more into a single application that easy to learn and fun to use.

Principal

Their support is horrible. Beginning the third week of plsatitudes and apologies, but NO FIX to a basic, fundamental requirement to sync my calendar.

Graphic Artist

Mailbird is great at consolidating all of your emails into one application. It's super simple to set up a new account.

But there is no way to contact by phone. All I get is a computer generated stupid answer to my questions.

Mailbird offers a once-off licence purchase which a great plus for such a powerful email application.

Vice Director for External Affairs

Support team is very quick to respond and are indeed helpful. Even before I got my Mailbird Pro, they have been very responsive.

Flawed software and terrible customer service.

Teaching Assistant

Support for 3+ accounts with an inexpensive one-time purchase of the pro version, lot's of integrated apps ranging from Google apps to Whatsapp and Dropbox. Responsive and helpful technical support.

Mail Management Software with amazing features.

Great alternative to Outlook if you are looking to avoid Microsoft’s high prices. Easy to use and updated often.

Marketing

Mailbird is a good looking app, with themes integrated, there is also a dark theme. You can add many different accounts.

I started to like emailing when it finally look nice and pretty. If you don't need complex mailing client and looking for something good looking and useful - that's it.
