MailerLite Integrations I Actually Use to Grow a WordPress Email List

You’ve got MailerLite set up, your WordPress site is live, and now you want the two talking to each other so subscribers actually land in your lists. The tricky part is figuring out which connection method fits what you’re trying to do, because “MailerLite integrations” can mean a giveaway, a popup, a checkout flow, or a no-code automation.

I run MailerLite alongside WordPress on my own sites, so this is the list I’d hand a friend who asked me where to start. I’ll walk through the MailerLite integrations I actually use to grow an email list, what each one is best for, and the one I reach for first.

Integration	Best for	Free plan	Pricing model
RafflePress	Growing a list fast with a giveaway	Yes (Lite)	One-time
SeedProd	Landing pages and opt-in pages	Yes	Annual
OptinMonster	Exit-intent popups and targeting	No	Annual
WPForms	Custom signup and contact forms	Yes (Lite)	Annual
Thrive Leads	List-building forms and A/B testing	No	Annual
MemberPress	Membership onboarding emails	No	Annual
WooCommerce	Store and abandoned-cart emails	Yes (core)	Free core
BigCommerce	Headless store and customer sync	No	Monthly
WP Charitable	Donor and fundraising follow-up	Yes (Lite)	Annual
Zapier	Connecting MailerLite to other apps	Yes	Freemium

How I Picked These MailerLite Integrations

I run MailerLite alongside WordPress on my own sites, so I focused on the integrations I have actually set up and connected, not every app in MailerLite’s directory.

Here is what I weighed:

• Real WordPress connection: it connects to MailerLite from inside WordPress, not just through a generic embed.
• What it grows: whether it adds subscribers, recovers sales, or onboards members.
• Setup effort: how long it takes to connect and get a working form or automation live.
• Free option: whether you can test it before paying.

If you only want one answer for growing a list, mine is RafflePress. A giveaway pulls in subscribers faster than a static form, and the entries flow straight into MailerLite.

What Is MailerLite?

MailerLite is an email marketing service that lets you build forms, send campaigns, and automate emails. You get customizable templates, subscriber management, automation workflows, and reporting in one place.

Connecting it to WordPress means you can capture leads from your pages and forms and drop them into the right MailerLite list automatically. That’s the whole reason the integrations below matter: they decide how subscribers get from your site into your email tool.

Getting Started With MailerLite on WordPress

Before any integration can grow your list, you need a MailerLite account connected to WordPress. Here’s the setup I follow.

Step 1: Sign Up for MailerLite

Visit the MailerLite website and create a free account or pick a plan that fits your list size. The free plan covers up to 500 subscribers and 12,000 emails a month, which is plenty for testing the connection.

Step 2: Install the MailerLite Plugin

Install the MailerLite plugin on your site. Go to Plugins » Add New, search for the MailerLite plugin, then install and activate it.

Step 3: Connect Your API Key

Open the MailerLite tab in your WordPress dashboard and follow the prompts to connect your account. Enter your MailerLite API key, which you’ll find in your MailerLite account settings.

Step 4: Create Your Signup Forms

Once you connect MailerLite, you can build signup forms that let visitors subscribe straight from your WordPress site. Drop them on a page and you’re collecting subscribers.

One thing worth clarifying is the official MailerLite plugin connects through your account so subscribers sync automatically, while a plain embed code just drops a form on the page without the same two-way connection.

For anything beyond a basic form, the plugin or a dedicated integration below gives you more control over where subscribers land.

Essential MailerLite Integrations for WordPress

With MailerLite connected, here are the integrations I’d actually set up, grouped by what each one does best for growing your list.

1. RafflePress: Best for Growing a List Fast With a Giveaway

Pricing	One-time, from $39.50/year for the entry tier
Free Plan	Yes (Lite, for testing the basic widget)
Standout Features	🔹 Direct MailerLite list integration 🔹 30+ giveaway entry actions 🔹 Built-in giveaway landing pages
Best For	Growing a WordPress email list quickly with a giveaway

RafflePress is the giveaway plugin I use to grow my own list, and it’s the one I reach for first when the goal is subscribers. By connecting it to MailerLite, you can run a contest where every entry adds someone to your email list.

The piece that matters here is the “Join an Email Newsletter” entry action. In the action settings, you connect directly to MailerLite, so anyone who enters to win is added to your email list without you touching a spreadsheet.

From there you can add bonus entry actions like referring a friend or following you on social, which is how a single giveaway can pull in subscribers from channels you don’t normally reach.

Publishing is quick too. You can use the RafflePress block, a shortcode, or a distraction-free giveaway landing page built right in the plugin.

Pros

• Connects directly to MailerLite from inside WordPress
• 30+ entry actions and a built-in winner picker, rules generator, and spam protection
• Built-in landing pages, so you don’t need a separate page builder

Cons

• The full integration set needs a paid plan
• Only works on self-hosted WordPress sites

The free Lite version is really only useful for testing the basic widget. The MailerLite integration and most entry actions live in the paid plans, so treat Lite as a trial, not a production setup.

My Verdict: If your number one goal is more subscribers, start here. A giveaway brings in people a static form never will, and the MailerLite connection means none of those entries slip through the cracks.

Remember: RafflePress is a WordPress plugin and only works on self-hosted WordPress websites.

2. SeedProd: Best for Landing and Opt-In Pages

Pricing	Annual, from around $39.50/year
Free Plan	Yes
Standout Features	🔹 Direct MailerLite opt-in integration 🔹 Drag-and-drop page builder with hundreds of templates 🔹 Coming soon, maintenance, and 404 page modes
Best For	Building landing and opt-in pages that feed your lists

SeedProd is the drag-and-drop website builder I use to build my own pages, and it connects to MailerLite directly. When the job is a dedicated opt-in page rather than a giveaway, this is where I go.

You pick a template from the landing page designs, then add opt-in forms that drop new subscribers straight into your MailerLite lists. No code, and you can preview on mobile before publishing.

It also handles coming soon, maintenance, 404, and login modes, and works with Google Analytics and SEO plugins, so the same tool covers more than just opt-in pages.

Pros

• Direct MailerLite integration on opt-in forms
• Hundreds of templates and a true drag-and-drop editor
• Lightweight pages that load fast

Cons

• The MailerLite integration sits in the paid tiers
• It’s a page builder, so it won’t run popups the way a dedicated popup tool does

My Verdict: Reach for SeedProd when you want a purpose-built opt-in page or a coming soon page that captures subscribers while you build the rest of your site.

3. OptinMonster: Best for Exit-Intent Popups and Targeting

Pricing	Annual, from around $7/month billed yearly
Free Plan	No
Standout Features	🔹 Exit-intent and behavior-based targeting 🔹 Drag-and-drop popup builder 🔹 A/B testing and analytics
Best For	Converting existing traffic with targeted popups

OptinMonster is a lead generation tool I’m deeply familiar with from the WordPress ecosystem, and it’s used on more than 1.2 million sites. Where RafflePress brings new people in, OptinMonster catches the traffic you already have before it leaves.

Its targeting is the draw. You can connect it to MailerLite and trigger popups, slide-ins, and other opt-ins based on what a visitor is doing, then A/B test them.

Pros

• The strongest targeting and trigger options of any opt-in tool here
• Built-in A/B testing and analytics
• Connects to MailerLite and most other email and CRM platforms

Cons

• No free plan
• More than you need if you only want a simple newsletter form

My Verdict: Best suited to anyone with steady traffic who wants to convert more of it. If your site is brand new with few visitors, a giveaway will move the needle faster than a popup.

4. WPForms: Best for Custom Signup and Contact Forms

Pricing	Annual, from around $49.50/year
Free Plan	Yes (WPForms Lite)
Standout Features	🔹 MailerLite integration that maps fields to groups 🔹 Drag-and-drop form builder 🔹 Conditional logic and payment integrations
Best For	Custom newsletter, contact, and survey forms

WPForms is the form builder I use for every form on my sites, and it connects to MailerLite so submissions add people to the right groups automatically.

Beyond newsletter signups, you can build contact forms, surveys, and feedback forms, then route submissions to MailerLite based on what someone selected. Conditional logic, file uploads, and Stripe or PayPal payments are all there too.

Pros

• Clean MailerLite integration with field-to-group mapping
• Handles every form type, not just signups
• Free Lite version to start

Cons

• The MailerLite addon needs a paid plan
• It’s a form tool, so it won’t run targeted popups

My Verdict: The right pick when you want full control over a signup or contact form and want every submission to land cleanly in MailerLite.

5. Thrive Leads: Best for List-Building Forms and A/B Testing

Pricing	Annual, part of the Thrive Suite
Free Plan	No
Standout Features	🔹 Pop-ups, ribbons, and slide-in opt-ins 🔹 A/B testing on forms 🔹 Trigger and targeting rules
Best For	Testing and optimizing list-building forms

Thrive Leads is a list-building plugin I’m familiar with from the wider WordPress world, and it integrates with MailerLite to push new subscribers to your lists. It covers similar ground to OptinMonster, with a focus on opt-in form variety.

You get pop-ups, sticky ribbons, slide-ins, and inline forms, plus A/B testing so you can compare designs and triggers. If you already own the Thrive Suite, it’s a natural fit.

Pros

• Wide range of opt-in form types
• Solid A/B testing built in
• Strong value if you already use Thrive Suite

Cons

• No standalone free plan
• Overlaps heavily with OptinMonster, so you rarely need both

My Verdict: A genuinely good choice for Thrive Suite owners who want their opt-in forms and email tool talking to each other. If you’re not already in that ecosystem, OptinMonster is the easier starting point.

6. MemberPress: Best for Membership Onboarding Emails

Pricing	Annual, from around $179.50/year
Free Plan	No
Standout Features	🔹 Adds new members to MailerLite automatically 🔹 Membership levels and content dripping 🔹 Works with major payment gateways
Best For	Onboarding and nurturing paying members

MemberPress is a WordPress membership plugin I know well from the ecosystem, and its MailerLite integration is about onboarding rather than acquisition. When someone joins, they get added to your list automatically.

That means new members can drop into an onboarding sequence, get exclusive updates, and receive renewal reminders without manual work. You can also set membership levels, restrict content, and drip lessons over time.

Pros

• Automatically syncs members to MailerLite for onboarding
• Full membership management and content dripping
• Works with the payment gateways most sites already use

Cons

• No free plan
• Only relevant if you’re actually running a membership site

My Verdict: Worth it specifically for membership sites that want every new member greeted by a proper email sequence. If you’re not selling memberships, the other tools here fit better.

7. WooCommerce: Best for Store and Abandoned-Cart Emails

Pricing	Free core plugin (paid extensions optional)
Free Plan	Yes (core is free)
Standout Features	🔹 Abandoned-cart and post-purchase emails 🔹 Segment by purchase history 🔹 Order and shipping notifications
Best For	Online stores that want behavior-based emails

If you run a store on WooCommerce, connecting it to MailerLite turns customer behavior into automated emails. You can recover abandoned carts, send post-purchase follow-ups, and segment by what people actually bought.

WooCommerce also pairs with page builders like SeedProd, so you can build a custom unsubscribe page that offers an incentive to stay on your list.

Pros

• Core plugin is free
• Behavior-based automations like cart recovery and order follow-ups
• Segment subscribers by purchase history

Cons

• The MailerLite connection usually needs an extension or Zapier
• Setup takes longer than a simple signup form

My Verdict: The default choice for WordPress store owners. The abandoned-cart emails alone tend to pay for the setup time.

8. BigCommerce: Best for Headless Stores and Customer Sync

Pricing	Monthly, from around $29/month
Free Plan	No (free trial only)
Standout Features	🔹 Customer data sync with MailerLite 🔹 Segment by purchase and browsing behavior 🔹 Works alongside WordPress
Best For	Larger stores running BigCommerce with WordPress

BigCommerce connects to MailerLite much like WooCommerce does, syncing customer data so you can segment your list and automate campaigns. It’s the option for stores that run BigCommerce as the commerce engine behind a WordPress front end.

You can target customers by purchase history or browsing behavior and send cart reminders, recommendations, and promotions. If you want more ideas for the campaigns themselves, our guide to eCommerce promotion ideas pairs well with this setup.

Pros

• Syncs customer data for segmented campaigns
• Scales well for larger catalogs
• Works alongside a WordPress site

Cons

• No free plan, and pricing is monthly
• Heavier than most WordPress site owners need

My Verdict: Pick BigCommerce over WooCommerce only if you’ve already chosen it as your store platform. For most WordPress users, WooCommerce is the simpler MailerLite path.

9. WP Charitable: Best for Donor and Fundraising Follow-Up

Pricing	Annual, with a free Lite version
Free Plan	Yes (Lite)
Standout Features	🔹 Adds donors to MailerLite automatically 🔹 Donation forms with custom fields and goals 🔹 Segment by giving history
Best For	Nonprofits nurturing donors and supporters

WP Charitable is a fundraising and donations plugin, and its MailerLite integration keeps you in touch with the people who give. New donors get added to your list automatically, so they receive updates and campaign news.

You can build donation forms with custom fields and goals, then send thank-you emails, receipts, and follow-up campaigns. Segmenting by giving history lets you tailor what each supporter hears.

Pros

• Adds donors to MailerLite with no manual export
• Donation forms with goals and custom fields
• Free Lite version to start

Cons

• Only relevant for fundraising and nonprofit sites
• Advanced features need a paid plan

My Verdict: If you’re raising money on WordPress, this is the cleanest way to turn one-time donors into an engaged email audience.

10. Zapier: Best for Connecting MailerLite to Other Apps

Pricing	Freemium, paid plans from around $19.99/month
Free Plan	Yes (limited tasks)
Standout Features	🔹 Connects MailerLite to thousands of apps 🔹 No-code automation “Zaps” 🔹 Trigger emails from events in other tools
Best For	Linking MailerLite to apps with no native integration

Zapier is the catch-all. When a tool doesn’t have a native MailerLite integration, Zapier bridges the gap with no-code automations called Zaps.

It’s one of the automation tools I lean on when two apps won’t talk directly.

For example, you can add new sign-ups from a Google Sheets form to MailerLite, send a welcome email when someone takes an action elsewhere, or sync subscriber data across platforms. It runs quietly in the background once set up.

Pros

• Connects MailerLite to thousands of apps
• No code required
• Free tier for low-volume automations

Cons

• A native integration is usually simpler when one exists
• Higher task volumes need a paid plan

My Verdict: Keep Zapier in your back pocket for the connections nothing else covers. Use native integrations first, and reach for Zapier when there isn’t one.

Connecting MailerLite to Tools Beyond WordPress

A lot of MailerLite questions aren’t about WordPress at all, they’re about the other apps in your stack. Here’s how MailerLite connects to the tools people ask about most, usually through a native integration or Zapier.

• Airtable: Sync subscribers to or from an Airtable base through Zapier to keep records in one place.
• Google Sheets: Add new spreadsheet rows as MailerLite subscribers, or log new subscribers back to a sheet.
• Google Forms: Push Google Forms responses into MailerLite as new subscribers via Zapier.
• Jotform: Use Jotform’s native MailerLite integration to send form submissions straight to your lists.
• Slack: Get a Slack message when someone subscribes, so your team sees new leads in real time.
• Salesforce: Connect MailerLite to Salesforce through Zapier to keep email and CRM contacts in sync.

MailerLite Integrations: Frequently Asked Questions

Does MailerLite integrate with WordPress directly, or do I need a plugin?

MailerLite has an official WordPress plugin that connects through your account, which is the easiest route. You can paste embed code for a basic form without a plugin, but the plugin and dedicated integrations give you automatic syncing and more control over where subscribers land.

Which MailerLite integration is best for growing an email list with a giveaway?

RafflePress is the one I use for this. Its “Join an Email Newsletter” entry action connects directly to MailerLite, so every giveaway entry adds a subscriber to your list, and bonus actions like referrals and social follows help a single giveaway reach beyond your existing audience.

Does MailerLite work with WooCommerce for abandoned cart emails?

Yes. Connecting MailerLite to WooCommerce lets you automate emails based on customer behavior, including abandoned cart reminders, post-purchase follow-ups, and product recommendations. You can segment your list by purchase history to keep those emails relevant.

Can I connect MailerLite to Airtable, Google Sheets, or Jotform?

Yes. Jotform has a native MailerLite integration, and Airtable and Google Sheets connect through Zapier. With a Zap, new rows or form responses can become MailerLite subscribers automatically, so you don’t have to export and import lists by hand.
