The Official MailerLite signup forms plugin makes it easy to grow your newsletter subscriber list from your WordPress blog or website. The plugin automatically integrates your WordPress form with your MailerLite email marketing account.
If you don’t have MailerLite account yet, you can signup for a FREE trial here.
Once you activate the plugin, you’ll be able to select and add any of the pre-built webforms from your MailerLite account or create a new form from scratch. You can place the form in the sidebar using a widget or use a shortcode to put it wherever you want.
Setup is fast and easy! You just need to enter your MailerLite account API code and you’re all set.

I signed up with mailerlite to manage newsletters (as opposed to ecommerce abandoned cart flows etc). I made an embedded signup form for newsletter subscription. THEN I learned that I needed this very specific plugin to be able to embed it on my website with ease.
I installed the plugin. It did not connect to mailerlite through my existing WooCommerce integration, even though this was a plugin that I didn’t want but had to have because I lack coding knowledge beyond basic html.
I spent more than an hour trying to troubleshoot this – there was no point making a new API code because I was already integrated with WooCommerce. What was not clear via any online source was that it needed the exact same API code to be pasted into the API field, because even though this has ONE JOB and SHOULD integrate with the foundational mailerlite plugin, it just… doesn’t. So I pasted the WooCommerce API code into the API field and now it is connected.
Just updating here in case anyone else had the same issue and ran out of patience.
I’ve had a similar experience to another commenter. Initially the plugin worked well. But later when I click to edit my form, it would redirect to MailerLite website and say “Form not found”. So I tried two things – created form on their website – result is that I can’t see it in my WordPress plugin (even after reinstalling plugin). Second thing I tried – created a from inside the WordPress plugin – result – even though the subscription says successful, contact is not added to any of the lists. I also created another list on their website, but it wasn’t showing in the plugin. After fruitless two hours, I’ve deleted the plugin, will use someting else
My experience with MailerLite has been simply disastrous.
The problem does not concern only the WordPress plugin, but the entire platform.
After numerous attempts the result was always the same:
forms display a success message, but users are NOT added to any list.
This happens both from WordPress and directly from the MailerLite web interface.
A system that communicates “subscription successful” when the subscription has not actually occurred is, quite simply, unreliable.
The interface is confusing, the logic opaque, and the complete lack of meaningful error feedback makes it impossible to understand what is going wrong. For such a basic function as subscriber management, this is unacceptable.
After hours wasted on tests and checks, I uninstalled everything.
I cannot recommend MailerLite to anyone looking for a simple, transparent, and reliable tool.
Plugin does not apply the styling to the form. Much easier to just use the JavaScript to embed forms.
The day before our email is validated, the next day we’re asked to validate it by installing incomprehensible codes on our website!
We understand nothing. I think we’re going to look for another, simpler plugin.
