10 Best Email Marketing Plugins for WordPress
If you run a WordPress website, you already know that traffic alone does not pay the bills. Visitors come, they read a post, and then most of them leave without ever coming back. Email marketing is the single best way to fix that problem. It lets you capture a visitor’s attention once and then keep talking to them for months or years afterward.
The tricky part is that WordPress does not come with email marketing built in. You need a plugin to collect subscribers, connect to a sending service, and automate the follow up messages. With so many options in the plugin directory, picking the right one can feel overwhelming.
That is exactly why we put this list together. Below you will find the 10 best email marketing plugins for WordPress in 2025, along with what each one does well, who it is best suited for, and roughly what it costs. By the end of this guide you should have a clear idea of which plugin fits your site.
Why Email Marketing Still Matters for WordPress Sites
Before we get into the list, it is worth explaining why email marketing deserves a spot in your strategy at all, especially when social media and paid ads get so much attention these days.
Email gives you something social platforms never will: ownership. Your subscriber list belongs to you. An algorithm change on Instagram or a sudden policy shift on a search engine cannot take your list away. As long as you keep your emails useful and relevant, you have a direct line to people who already showed interest in what you offer.
Email also converts extremely well. Studies from major sending platforms consistently show that email marketing returns far more revenue per dollar spent than most other channels. For a blog, an online store, or a service business, that return adds up fast.
With that context out of the way, let us look at the plugins.
1. OptinMonster
OptinMonster is one of the most popular conversion tools for WordPress, and for good reason. It is not strictly an email sending service, but rather a lead generation plugin that helps you build popups, floating bars, slide ins, and full screen welcome mats that turn visitors into email subscribers.
What makes it stand out
The drag and drop builder is genuinely easy to use, even if you have never built a form before. You can target campaigns based on behavior, such as showing a discount popup right when someone is about to leave your page through exit intent detection. It also integrates with almost every major email service, including Mailchimp, Constant Contact, AWeber, and ConvertKit.
Best for
Bloggers and online stores that want to grow their list quickly through smart popups and targeted offers rather than a simple static form.
Pricing
Plans start around 9 dollars a month when billed yearly, with higher tiers unlocking more advanced targeting rules.
2. Mailchimp for WordPress (MC4WP)
If you already use Mailchimp to send your campaigns, this plugin is close to a must have. Mailchimp for WordPress, often shortened to MC4WP, connects your WordPress forms directly to your Mailchimp audience without any coding required.
What makes it stand out
Setup takes just a few minutes. You connect your Mailchimp account with an API key, choose which audience new subscribers should join, and place a shortcode wherever you want the form to appear. It also plays nicely with popular form builders like Contact Form 7, Gravity Forms, and WPForms, so you can add email opt in fields to forms you already have.
Best for
Anyone already committed to the Mailchimp ecosystem who wants a simple, dependable connection between their site and their list.
Pricing
The core plugin is free. A paid version with extra features like multi page forms and Google Analytics tracking costs a one time fee.
3. FluentCRM
FluentCRM takes a different approach compared to most plugins on this list. Instead of connecting to an outside service, it runs entirely on your own WordPress site, which means no monthly fees for a separate email platform and full ownership of your subscriber data.
What makes it stand out
FluentCRM includes contact management, tagging, list segmentation, automation sequences, and detailed email campaign reporting, all inside your WordPress dashboard. Because it is self hosted, you only pay for your sending service, such as Amazon SES, which can cost just a few dollars a month even for a large list.
Best for
Site owners who want complete control over their data and are comfortable setting up a transactional email service to handle actual delivery.
Pricing
A free version is available, and the paid plans start at a reasonable yearly rate that unlocks automation funnels and advanced segmentation.
4. Constant Contact Forms by MailMunch
Constant Contact is a long standing name in email marketing, and its official WordPress plugin, built by MailMunch, makes it simple to design opt in forms and sync them straight into your Constant Contact account.
What makes it stand out
The visual builder lets you create popups, embedded forms, and landing pages without touching any code. It also includes basic analytics so you can see how each form is performing, and it supports A/B testing to compare different form designs.
Best for
Small businesses that already use or plan to use Constant Contact for their broader email marketing needs.
Pricing
The plugin itself is free, though you will need a Constant Contact subscription, which starts at a modest monthly rate depending on your list size.
5. HubSpot for WordPress
HubSpot offers a full suite of marketing tools, and its WordPress plugin brings a good chunk of that power directly into your site. Beyond email marketing, it includes live chat, CRM contact tracking, and simple form building.
What makes it stand out
Every form submission automatically becomes a contact record inside your HubSpot CRM, which means you can track a subscriber’s entire journey from their first visit through every email interaction that follows. The free plan is genuinely generous for smaller sites.
Best for
Growing businesses that want their email marketing tied directly into a broader sales and customer relationship system.
Pricing
A solid free tier is available, with paid marketing hub plans scaling up based on contact count and feature needs.
6. Icegram Express
Icegram Express is a self hosted email marketing plugin similar in spirit to FluentCRM, but with a slightly simpler feature set that makes it approachable for beginners.
What makes it stand out
You can build newsletters, autoresponder sequences, and broadcast campaigns right from your WordPress dashboard. It connects to sending services like SendGrid, Amazon SES, and SMTP providers to actually deliver the mail, which keeps ongoing costs low compared to paying for a separate all in one platform.
Best for
Bloggers and small business owners who want an affordable, self hosted alternative to services like Mailchimp without a steep learning curve.
Pricing
There is a capable free version, with premium add ons available for automation and advanced reporting.
7. Bloom by Elegant Themes
Bloom is a popup and opt in form plugin from Elegant Themes, the same company behind the well known Divi theme. It focuses purely on capturing email addresses through attractive, high converting forms.
What makes it stand out
Bloom offers six different opt in form types, including popups, fly ins, below post forms, and content locks that reveal hidden content once someone subscribes. It also includes split testing so you can compare which design and copy converts best, and it connects to more than a dozen email marketing services.
Best for
Content heavy sites and blogs that want a wide variety of visually polished form styles to test against each other.
Pricing
Bloom is included with an Elegant Themes membership, which also grants access to Divi and other tools, priced as an annual or lifetime package.
8. Sumo
Sumo is a lightweight suite of website growth tools, and its email capture features remain a favorite among smaller sites and solo creators who want something quick to set up.
What makes it stand out
Sumo includes list building tools like welcome mats, scroll boxes, and smart bars, all managed from a single dashboard. It also shows you simple analytics about which forms are converting, so you are not just guessing about what works.
Best for
Solo bloggers, newsletter writers, and small ecommerce shops that want an easy, no fuss way to start building a list.
Pricing
A free plan covers the basics, and paid plans unlock more advanced targeting and remove Sumo branding from your forms.
9. Newsletter Glue
Newsletter Glue is built specifically for WordPress users who publish content regularly and want to turn their posts into newsletters with minimal extra effort.
What makes it stand out
It integrates directly into the WordPress block editor, letting you write a post and a newsletter version of it at the same time using special newsletter only blocks. It connects with services like Mailchimp, ConvertKit, and MailerLite, and it is a favorite among independent writers who publish frequently.
Best for
Writers, publishers, and content creators who want their blog posts to double as newsletter content without duplicating their workload.
Pricing
A free version is available for basic use, with paid tiers unlocking automation and premium blocks for a monthly fee.
10. WPForms
WPForms is best known as a general purpose form builder, but its email marketing integrations make it worth including here. You can add subscriber opt in checkboxes and fields to any form on your site, from contact forms to surveys.
What makes it stand out
WPForms connects with virtually every major email marketing service through its add ons, including Mailchimp, Constant Contact, Drip, GetResponse, and ActiveCampaign. Because it is primarily a form plugin, you also get spam protection, conditional logic, and a huge template library along with your email signup fields.
Best for
Site owners who want to combine general contact forms with email list building in a single, reliable plugin rather than running two separate tools.
Pricing
A limited free version called WPForms Lite is available, with paid plans starting at a yearly rate that unlocks the email marketing addons and payment integrations.
How to Choose the Right Plugin for Your Site
With ten solid options on the table, picking one comes down to a few practical questions.
Do you already use an email service? If you are locked into Mailchimp, Constant Contact, or HubSpot, start with their dedicated plugin. The setup will be faster and the sync more reliable than a third party tool.
Do you want to avoid monthly service fees? Self hosted options like FluentCRM and Icegram Express let you own your data and only pay for sending, which can be significantly cheaper once your list grows past a few thousand subscribers.
Is your main goal collecting emails or automating a full journey? Tools like OptinMonster, Bloom, and Sumo are built primarily for list growth through popups and forms. If you need automation sequences and detailed contact tracking too, lean toward FluentCRM, Icegram Express, or HubSpot.
Do you publish content often? If your site revolves around regular blog posts, Newsletter Glue is worth a serious look since it turns your existing writing workflow into a newsletter workflow with almost no extra steps.
Final Thoughts
Growing an email list is one of the most reliable long term investments you can make in your WordPress site. The plugins covered in this guide, from popup specialists like OptinMonster and Bloom to full self hosted platforms like FluentCRM, each solve a different piece of the puzzle.
