The folks at MailerLite actually surprised me at how helpful they were in both the speed of their responses and the content of them too... like someone actually read my questions and actually answered them... not just sending me a link to their FAQ page, we've all had that kind of "no-help" help, and it can be maddening.

The ease at which I've been able to create these assets has been fantastic - and when I've hit a roadblock and asked Customer Support for assistance the responses I've received have been very prompt and detailed - providing sufficient information - including annotated screenshots - to help me resolve my issue quickly and efficiently.

Occasional slowness and lag

Founder

The website is rather slow and heavy with scripts, which can cause some frustration when using.

67% of reviewers feel negative about MailerLite’s performance and speed. Reviewers report that the platform can be slow to load, especially when importing contacts, navigating between sections, or editing large campaigns. Some users say the website and editor occasionally freeze or lag, which disrupts their workflow and causes frustration. They indicate that server delays and slow response times are noticeable during peak usage or after updates. Reviewers find these performance issues time-consuming, particularly when they need to complete tasks quickly or manage multiple projects.

Limited formatting flexibility

The rich text composer can be infuriating - the backspace button on the keyboard has some sort of bug in that scenario where it will just delete an entire email. But I've just got into the habit of writing in Word and copy pasting into the email editor.

48% of reviewers feel negative about MailerLite’s text and image formatting. Reviewers report challenges with the editor, such as restrictive blocks, limited font options, and image size constraints. Some users say formatting text and aligning images can be unintuitive, with issues like disappearing toolbars, cursor jumps, and difficulties in customizing layouts. They indicate that the visual builder offers limited choices and that certain tasks, like adding custom CSS or embedding media, are not straightforward. Reviewers find these limitations hinder their ability to create complex or visually unique designs.

Complex and clunky form management

Small Business Owner

It's also a small gripe, but editing forms takes a bit longer than it should, as you have to click through a few screens to finally save your updated form.

Content Creator

I tried embedding a form in my free Wordpress website but it didn't work even after the Mailerlite helpdesk also tried.

41% of reviewers feel negative about MailerLite’s forms functionality. Reviewers report that the form builder is not intuitive, requiring multiple steps and clicks to complete simple tasks. Some users say embedding forms on websites, customizing layouts, or linking forms to automations can be confusing and time-consuming. They indicate that the interface is sometimes slow to load, and options for advanced customization are limited. Reviewers find the process of managing and editing forms less efficient than expected, which impacts their ability to quickly capture leads or integrate with other tools.

Challenging account and domain processes

When you signup for Mailerlite's team takes 2-4 days to activate your account, so you can not use it instantly, you have to wait for their approval, I waited for 3 days :) and the website integration process is also strict.

59% of reviewers feel negative about MailerLite’s account and domain management. Reviewers indicate that the account approval process is strict, sometimes slow, and lacks transparency, leading to unexpected suspensions or access issues. Some users say domain authentication and verification are cumbersome, requiring technical steps that are not always clearly explained. They report difficulties with logging in, two-factor authentication, and managing multiple domains. Reviewers find it frustrating when accounts are limited or terminated without clear reasons, and they express concerns about the lack of effective appeal or recovery options.

Recurring bugs and glitches

The main problem I encounter is having to verify every time I sign in

Menopause Wellness & Weight Loss Coach

Sometimes there are glitches - there's an ongoing one that hasn't been resolved for several months.

42% of reviewers feel negative about MailerLite’s bugs and technical issues. Reviewers indicate that they encounter glitches in the editor, dashboard, and automation features, sometimes leading to confusion or extra work. Some users say they experience login problems, errors with forms or segments, and occasional system instability.

Operations

I have it linked to my store, for sales, linked to a landing page to capture emails, and the auto sequence works great.

Deliverability has also been solid, and the platform includes extras like landing pages, popups, and even a website builder without needing additional tools.

Especilist in Institutional Culture

It has some usefull social media management and help with that with some tools that join your campaigns and others landing pages with your own followers from your social media channels.

Office Manager

It's a little simple looking in the unpaid version, there are customisable options but the templates are hard to completely brand the way we want to.

The features (landing pages x10, email automations and HTML editors) and support for the cost is fantastic compared to other, better known competitors.

director

You have an automation that uses the email you made in the campaigns. But all future edits you wanted to do in that automation, it needs to be done in automation and not in the saved copy you made earlier.. wot?

Fantastic for starting a free email list with a 1k free subscriber cap after which you have to pay.

After my automation triggered their algorithm, they banned my account, despite the fact that I followed all their terms of use. When I reached out to customer support, I got a generic, copy-paste response, and they never replied to my follow-up.

I pay the same rate as someone emailing their list daily or weekly, but only keep in touch maybe once per quarter unless I'm launching something.

Founder, Publisher, and Chief Editor

I liked everything least. But *LEAST* of the least I liked how they took away the "free 1,000 subscribers" tier which we—a NONPROFIT publisher—needed to thrive (for God's sake, we send a total of 2,500 emails PER YEAR), without warning and without a transition plan of any kind.

Manager

MailerLite’s intuitive interface, robust customization, powerful automation, affordable pricing, and detailed analytics make it a top choice for businesses seeking an effective and user-friendly email marketing solution.

UI UX designer

The interface is clean, the navigation is intuitive, and the workflow feels well-designed from a UX perspective.

Also, the emails are responsive on every device, I can track clicks as I send the emails over and update the subscriber base via CSV

Admin

The drag-and-drop editor makes it quick to design professional campaigns, and the automation tools are powerful yet simple to set up.

Head of Marketing

Clean UX/UI design, sufficient formatting options for newsletters, easy email automation and group segmentation.

Owner and Lead Designer

MailerLite has been a great addition to my tech stack for managing my e-mail marketing for launches and campaigns.  

Later, when preparing to send the next batch (~500 emails), our account was terminated for an alleged Terms of Service violation.

Mailerlite becaome my choice because of how simple it was to set up automations, how it was designed to scale with my paying subscriber list, and how easy it was to implement.

Although essential, a few years ago they updated their software significantly from Mailerlite Classic to the newer Mailerlite, but users who had emails/automations in Mailerlite Classic could not transfer most of their work across, so had to redo it manually in the newer system.
