Email marketing still gives you direct access to a subscriber’s inbox, no algorithm deciding whether they see it, which is why it remains one of the higher-ROI channels available. This list covers 12 tools, a mix of self-hosted WordPress plugins and SaaS platforms with WordPress integrations, with a few important corrections on ones that have changed or disappeared.
Every entry below has been checked against the vendor’s own current site rather than repeating whatever a comparison article said a year or two ago. Three of the twelve have gone through a rebrand, a merger, or a real decline in active development since this list was first put together, and skipping that check is exactly how outdated “best of” lists end up recommending something that’s quietly stopped existing.
Why Use One
- Engagement. Direct, targeted emails reach people who’ve already opted in, a fundamentally warmer audience than cold social reach.
- Lead generation. Opt-in forms and popups turn anonymous visitors into a list you actually own.
- Retention. Ongoing email contact keeps existing customers engaged without repeated ad spend.
- Convenience. Managing campaigns from the WordPress dashboard beats juggling a separate platform for sites already built there.
12 Email Marketing Plugins and Platforms
1. FluentCRM
Confirmed active, now on FluentCRM 3.0 ($90-349/yr, all features included, no addon upsells). Self-hosted, so your contact data lives on your own server rather than a third-party platform, with deep WooCommerce and LearnDash integration. Needs SMTP configured for reliable sending, and there’s a real learning curve around its automation builder.
The self-hosted model is the real differentiator here. Because your subscriber data sits in your own WordPress database rather than a vendor’s cloud, you avoid the recurring per-contact pricing that eventually makes SaaS platforms expensive at scale, and you’re not exposed if the vendor changes its terms of service around what you can do with your own list. The tradeoff is that you’re responsible for your own email deliverability infrastructure, which is why a dedicated SMTP or transactional email service isn’t optional here the way it might feel with a fully managed SaaS platform.
2. Mailchimp
Still the best-known name in the category. Customizable templates, segmentation, automation, and analytics, with a free tier for small lists. Pricing climbs quickly as your subscriber count grows, worth checking current tiers against your actual list size before committing.
Mailchimp’s brand recognition means it’s often the default choice for people who haven’t researched alternatives, and that’s not necessarily a bad instinct for a first list. Its WordPress integration handles the basics well, syncing WooCommerce customer data and displaying signup forms without much configuration. The pricing curve is the thing to watch closely: a list that stays under a few thousand subscribers costs relatively little, but growth into the tens of thousands can make Mailchimp meaningfully more expensive than a self-hosted alternative like FluentCRM over a multi-year horizon.
3. weMail
Confirmed active. WordPress-native email campaigns, subscriber management, and reporting, positioned as one of the more affordable options in this list, with a genuine free tier to start.
weMail integrates with several third-party SMTP and email delivery services rather than building its own sending infrastructure from scratch, which keeps its own pricing lower but means deliverability quality depends partly on which sending service you pair it with. For a smaller list or a newer site still figuring out its email strategy, that combination of a low starting cost and flexibility on the sending side makes it a reasonable low-risk starting point.
4. Brevo (formerly Sendinblue)
Rebranded from Sendinblue in 2023, same company and platform. Email plus SMS marketing, transactional email, automation, and segmentation in one account.
The SMS channel is Brevo’s real point of differentiation from most of the other tools on this list, letting a single platform handle both email campaigns and text message marketing under one set of automation rules. That combination suits e-commerce brands and local businesses that want a unified view of a customer’s engagement across both channels, rather than running two disconnected tools that don’t share data.
5. OptinMonster
Lead-generation and conversion tool rather than a full email platform, exit-intent popups, scroll-triggered forms, A/B testing, and behavior-based targeting, meant to grow the list that a separate ESP then emails.
It’s worth being clear about what OptinMonster doesn’t do, since it gets grouped with full email platforms often enough to cause confusion. It has no email sending capability of its own. Its entire job is capturing an email address at the right moment through a well-timed popup or form, then handing that contact off to whichever ESP from this list actually sends the emails. Pairing it with FluentCRM or Mailchimp is a common combination for sites that want more sophisticated list-growth tactics than a plugin’s native forms provide.
6. MailPoet
Free (WordPress.org) for lists up to 1,000 subscribers, with a drag-and-drop editor and native WooCommerce integration. Automation is lighter than dedicated platforms like FluentCRM or Brevo, a reasonable tradeoff for simplicity.
MailPoet’s biggest appeal is how little setup it requires for a straightforward newsletter. It handles sending through its own infrastructure once you’re past the free tier, so there’s no separate SMTP configuration step the way FluentCRM or weMail require. For a blog or small store that mainly wants to send a weekly digest and the occasional promotion, that simplicity is worth more than the deeper automation options a more complex platform offers.
7. SendPress
Worth a real caution here: SendPress’s own site still displays a 2017 copyright notice and lists a PHP 5.6 minimum requirement, both strong signals this product hasn’t seen meaningful development in years, even though the site is technically still up and selling licenses. Test thoroughly before relying on it, or pick a more actively maintained option from this list.
PHP 5.6 reached end-of-life years ago and no longer receives security patches from the PHP project itself, which means a plugin still listing it as a minimum requirement almost certainly hasn’t been tested against anything close to current WordPress or PHP versions. Running an unmaintained plugin that touches your subscriber list and sends bulk email carries real security and deliverability risk, and this is one of the clearer cases on this list where the safer move is simply choosing a different tool.
8. Sumo (List Builder, now BDOW!)
Worth a direct correction: Sumo’s product rebranded to BDOW! a while back (confirmed elsewhere in this campaign, v1.44, 10,000+ installs), and the original sumo.com domain has since been sold off entirely, it now hosts an unrelated AI product with no connection to the email/list-building tool. Look for BDOW! directly rather than searching for “Sumo.”
This is a good example of why checking a tool’s current status directly matters more than trusting an older comparison article. Anyone who searched for “Sumo WordPress plugin” today and landed on the current sumo.com would find something entirely unrelated to list building, with no indication that the actual product moved. Searching for BDOW! by name, or finding it directly through the WordPress.org plugin directory, is the reliable path to the actual tool.
9. Contact Form 7 (Supporting Role Only)
Worth being honest about scope: Contact Form 7 is a form plugin, not an email marketing tool. It can feed form submissions into an email marketing service via integrations, but it doesn’t send campaigns, manage lists, or automate sequences on its own. Useful as a lead-capture front end paired with one of the actual ESPs above, not a standalone email marketing solution.
Its inclusion here is mainly to correct a common misconception, since Contact Form 7 shows up often enough in “email marketing plugin” searches that it’s worth clarifying what it actually is. Pairing it with a proper ESP through a plugin like FluentCRM’s Contact Form 7 integration, or a service like Zapier, is the realistic way to use it as part of an email marketing stack rather than as a replacement for one.
10. Drip
An e-commerce-focused SaaS platform (not a WordPress plugin in the traditional sense), with WooCommerce and Shopify integrations. Strong behavior tracking and workflow automation, but priced and featured for stores that have outgrown simpler tools, likely overkill for a basic newsletter.
Drip’s strength is behavioral automation tied specifically to purchase and browsing behavior, triggering different email sequences based on what a customer viewed, abandoned, or bought previously. That depth of behavioral targeting is genuinely valuable for a store with meaningful transaction volume, but it’s more infrastructure than most small sites need, and the pricing reflects that positioning.
11. FreshMail (Discontinued, Merged Into MailerLite)
Important correction: FreshMail’s own domain now redirects to a “moving to MailerLite” notice, meaning it’s no longer sold as an independent product. If you’re currently on FreshMail, MailerLite is the direct successor to migrate to.
For anyone still running FreshMail, this isn’t a distant risk to plan around eventually, it’s an active situation that needs a migration plan now. MailerLite has published its own guidance for FreshMail customers making the switch, and waiting too long risks losing access to campaign history or automation workflows built on the old platform.
12. Newsletter
Free (WordPress.org) plugin with unlimited subscribers and sends on the free tier, drag-and-drop composer, and segmentation. Premium unlocks automatic translation, professional template support, and more advanced targeting.
The unlimited free tier is unusual in this category, where most competitors cap the free plan at a specific subscriber count. That makes Newsletter worth a look for a site with a large list and a tight budget, though it’s worth testing deliverability carefully at scale, since sending through your own server’s infrastructure rather than a dedicated transactional email service can hurt inbox placement once volume grows past what a typical shared host handles comfortably.
Deliverability: The Part Most Comparisons Skip
A plugin’s feature list matters less than whether your emails actually land in the inbox instead of the spam folder, and deliverability is where self-hosted tools like FluentCRM, MailPoet, and Newsletter need the most attention from the site owner. Sending bulk email directly from a shared web host’s default mail configuration is one of the most reliable ways to get flagged as spam, since shared IP addresses often carry a poor sending reputation built up by other sites on the same server.
Setting up a dedicated transactional email service, such as Amazon SES, Postmark, or SendGrid, as the actual sending layer behind a self-hosted plugin fixes most of this. It’s an extra setup step that fully managed SaaS platforms like Mailchimp and Brevo handle for you automatically, which is part of what you’re paying for with their higher subscription pricing. Factor that setup time and any added SMTP service cost into a true comparison between self-hosted and SaaS options, rather than comparing sticker prices alone.
Compliance: GDPR, CAN-SPAM, and List Consent
Every tool on this list needs to be configured to meet basic email compliance requirements, and that responsibility sits with the site owner regardless of which plugin or platform gets chosen. GDPR requires clear, affirmative consent before adding someone to a marketing list if you have subscribers in the EU, and CAN-SPAM in the US requires an easy, working unsubscribe link and accurate sender information in every campaign.
Most of the platforms above include built-in unsubscribe handling and consent checkboxes, but the specific configuration, like whether a signup form uses single or double opt-in, is a choice the site owner makes, not something the plugin enforces automatically. Double opt-in, where a new subscriber has to confirm via a follow-up email before landing on the active list, produces a smaller but more genuinely engaged list and reduces spam complaints, which in turn protects your sender reputation with the mailbox providers that decide whether your future emails reach the inbox.
Self-Hosted Versus SaaS: The Real Tradeoff
This list splits fairly evenly between self-hosted WordPress plugins like FluentCRM, MailPoet, and Newsletter, and SaaS platforms like Mailchimp, Brevo, and Drip, and the choice between the two categories matters more than which specific tool within either category you pick. Self-hosted tools give you full ownership of your subscriber data and typically cost less at scale, but they push deliverability infrastructure, backups, and security updates onto whoever manages the site.
SaaS platforms handle all of that infrastructure for you in exchange for a subscription fee that grows with your list size. For a site owner without the time or technical comfort to manage SMTP configuration and monitor sender reputation, that tradeoff is often worth the extra cost. For an agency or a technically capable team running multiple client sites, the self-hosted route tends to pay for itself once you’re managing more than one list, since the same SMTP and deliverability setup can often be reused across projects.
Frequently Asked Questions
Can I use more than one of these tools together?
Yes, and it’s actually common. OptinMonster paired with FluentCRM or Mailchimp is one of the more frequent combinations, since OptinMonster handles list growth while the other tool handles sending and automation. Running two full-featured ESPs side by side is rarely worth the added complexity, but pairing a lead-generation tool with a sending platform is a genuinely useful combination.
How do I know if a plugin listed here is still actively maintained?
Check the plugin’s WordPress.org listing for its “last updated” date and tested-up-to WordPress version before installing anything, not just for the tools on this list but for any plugin handling something as sensitive as your subscriber data. A plugin that hasn’t been updated in over a year, or one still listing an end-of-life PHP version as its minimum requirement the way SendPress does, is a real warning sign worth taking seriously.
What happens to my list if my email platform shuts down or gets acquired?
This is exactly what happened with FreshMail and, in a different way, with Sumo’s rebrand to BDOW!. Most reputable platforms give existing customers advance notice and a migration path, as MailerLite has done for FreshMail customers, but it’s worth exporting your list and campaign data periodically regardless, so you’re never fully dependent on a vendor’s transition plan if a service does wind down.
Choosing the Right One
Define what you actually need first: automation depth, integration with your specific stack (WooCommerce, LearnDash, CRM), budget, and how quickly your list is likely to grow (some pricing models punish list growth harder than others). Test with a free tier or trial before committing to a paid plan, and revisit the choice periodically since pricing and features shift over time, as several corrections in this list demonstrate.
Getting More Out of Whichever One You Pick
- Build the list deliberately. Opt-in incentives (discounts, exclusive content) convert better than a bare “subscribe” form.
- Segment early. Even basic segmentation (new vs. returning, purchase history) beats blasting one message to everyone.
- Test subject lines. A/B testing open rates is one of the highest-leverage, lowest-effort optimizations available.
- Design for mobile first. Most email opens happen on a phone; a template that isn’t responsive loses readers immediately.
- Automate the obvious sequences. Welcome emails, abandoned cart reminders, and post-purchase follow-ups are worth automating before anything more elaborate.
- Track real metrics. Open rate, click-through rate, and unsubscribe rate tell you more than vanity subscriber counts.
Migrating Between Platforms Without Losing Your List
Switching email tools, whether by choice or because a platform gets discontinued the way FreshMail did, is more involved than exporting a CSV and importing it somewhere new. Automation workflows, tags, and segment definitions rarely transfer automatically between platforms, so budget real time to rebuild them rather than assuming a straightforward import handles everything.
It’s also worth checking your new platform’s re-engagement or sunset policy for an imported list. Some ESPs require imported contacts to reconfirm their subscription before you can email them at full volume, both as a spam-prevention measure and to protect the new platform’s own sender reputation from inheriting a list they didn’t build the relationship with directly. Planning for that reconfirmation step ahead of a migration avoids a nasty surprise where your open rates crater right after a switch.
