Mailchimp Alternatives That Live Entirely Inside wp-admin

One vendor states the difference plainly: plans are priced by the number of websites, not by the size of your list. FluentCRM at $103 a year for one site, with unlimited contacts. Against a platform that charges by contact and raises the bill every time your audience grows, that is not a discount, it is a different pricing axis entirely.
Moving your list into WordPress changes more than the invoice, though, and some of what changes is not in your favour. This article models the cost at three list sizes, sets out honestly what you gain and lose by bringing contacts in-house, and covers migrating without destroying the segmentation you spent years building.
Verified August 2026. Platform pricing varies by feature tier and changes often; the figures here show the shape of the comparison rather than a quote.
Per contact versus per site
Per-contact pricing charges you for holding data. Per-site pricing charges you for software. The consequences run further than the monthly figure.
Per-contact billing penalises exactly what you are trying to do. Growing your list, the goal of every acquisition effort you run, makes your costs rise. Worse, it creates a quiet incentive to hold less data: pruning subscribers you might have re-engaged, and deleting historical contacts you would rather keep, because storage has a monthly price.
Per-site billing removes that pressure entirely. Twenty thousand contacts or two hundred thousand, the software costs the same. You keep everybody, keep the histories, and make list decisions on merit rather than on cost.
Modelled out: at 5,000 contacts a platform plan is commonly around $75 a month, roughly $900 a year, against $103. At 25,000 contacts the platform is frequently past $200 a month, so $2,400 a year, still against $103. At 100,000 contacts platform pricing runs into four figures monthly while the plugin has not moved. The difference is not marginal, and it compounds annually.
Delivery is the honest asterisk. Self-hosted software still needs a sending service, which is a few dollars a month at ordinary volumes. Add it in and the comparison barely changes.
What moving in-house actually changes
- You own the data outright. Contacts sit in your database, exportable and queryable, with no platform between you and your own audience. For anyone who has watched a service change its terms, that is worth something on its own.
- Site behaviour becomes available to email. Purchases, course progress, membership level and form submissions are all in the same database, so segmenting on them needs no integration and no sync delay. This is the genuine capability advantage.
- Deliverability becomes yours. The platform was managing sender reputation on your behalf. Now you choose a sending service, authenticate your domain and watch your own bounce and complaint rates.
- Your database grows. A hundred thousand contacts with activity histories is real data on hosting that was sized for a website. Budget for adequate hosting rather than discovering this during a campaign.
- There is no support desk. Plugin vendors support their software; nobody is accountable for your open rates. If email drives your revenue, decide who owns that internally.
- Migration is one-way in practice. Moving 40,000 contacts with their tags and histories is a project. Do it deliberately, not as an experiment you expect to reverse.
The 6 options compared
1. FluentCRM
The clearest expression of the per-site model and the strongest all-round replacement. $103, $199 and $399 a year, tiers counting websites rather than contacts.
Contacts, tags, lists, segments, automation sequences and per-contact activity timelines are all present, which is a genuine platform feature set rather than a newsletter tool. Its advantage over the platform you are leaving is the integrations: because it lives in the same database as your store, your course platform and your membership plugin, a segment like “bought this, has not opened in ninety days, is not a member” is a native query rather than a sync job. The interface is closer to a modern marketing tool than to a WordPress plugin, which makes the transition comfortable for somebody used to a platform. If you are reading this article because of the pricing, this is the product the pricing argument is about.
- Pricing: $103/yr per site, unlimited contacts
- Automation: Strong, visual sequences
- Best for: Most sites leaving a per-contact platform
- Watch out for: Sending service is a separate decision
2. Groundhogg
The other serious WordPress CRM, and the one to look at when the requirement is sales process rather than newsletters.
Its model leans toward contact management, funnels and pipelines, which suits a business tracking deals and stages rather than one broadcasting to an audience. Automation is capable and the funnel builder expresses multi-step processes clearly. Like its main rival it stores everything in your database and prices by site rather than by contact, so the core economic argument holds identically. Where it differs is emphasis: choose it if what you are replacing is closer to a lightweight sales CRM with email attached, and choose the alternative if you are replacing a broadcast platform. Check its integration coverage against the specific plugins your site runs before committing.
- Pricing: Per site, unlimited contacts
- Automation: Strong, funnel oriented
- Best for: Sales pipelines rather than broadcasts
- Watch out for: Verify integrations with your stack
3. MailPoet
Lives in wp-admin but keeps the pricing model you were escaping. Free to 500 subscribers and 5,000 emails a month, Business plans from around $10 a month scaling with list size.
For a store under a few thousand subscribers this is a strong product: excellent composer, deep commerce integration, abandoned-cart and post-purchase automations that work with almost no setup. If your motivation is convenience and a tidier workflow rather than pricing, it delivers that well. But it does not solve the problem this article is about, because the bill still rises with the list. A useful way to think about it: this is the right destination if you are leaving a platform for workflow reasons, and the wrong one if you are leaving because of what 25,000 contacts costs.
- Pricing: Per subscriber, monthly
- Automation: Good, commerce focused
- Best for: Stores under a few thousand contacts
- Watch out for: Does not fix per-contact pricing
4. FunnelKit Automations
The commerce-first option, worth naming separately because store automation is a distinct problem from list marketing.
Where a general CRM treats an order as one event among many, this is built around the purchase lifecycle: cart abandonment, post-purchase sequences, win-back campaigns and revenue attribution per automation. For a store whose email is almost entirely transactional and lifecycle-driven rather than editorial, that focus produces better results with less configuration. It stores contacts in your database and prices per site, so the economic argument holds. Where it is narrower is general broadcasting and content marketing, which are secondary concerns in its design. Run it alongside a newsletter tool if you need both, or choose a general CRM if the split is roughly even.
- Pricing: Per site
- Automation: Strong, purchase lifecycle
- Best for: Stores where email follows orders
- Watch out for: Weaker for editorial broadcasting
5. The Newsletter Plugin
The zero-cost floor, and a reminder that plenty of platform subscriptions are paying for capability nobody uses.
Free, no subscriber cap, campaigns and automated post digests included. If an honest audit of your platform usage shows that you send a weekly broadcast and never touch the automation builder, then you are paying several hundred dollars a year for a list to sit somewhere. This replaces that for nothing, leaving only delivery to pay for. What you give up is tagging depth, automation, contact timelines and the integrations that make a CRM useful, so it is the right answer only when your actual requirement is broadcasting. Do the audit before assuming you need more; the results are often surprising.
- Pricing: Free
- Automation: Limited
- Best for: Sites that only ever broadcast
- Watch out for: No real segmentation or timelines
6. Staying on the platform
The expensive answer, and the right one in identifiable circumstances.
Stay if email is your primary revenue channel and nobody on your team wants to own deliverability, because managed sender reputation and an accountable support relationship are worth real money in that situation. Stay if your marketing team lives in the platform daily and retraining them costs more than the licence. Stay if you depend on integrations with tools outside WordPress that the plugin ecosystem does not reach. Move if the list is large, the usage is moderate, and the site already holds the behavioural data you want to segment on. That last combination describes a great many WordPress businesses, which is why this category exists.
- Pricing: Per contact, monthly
- Automation: Strong, with managed deliverability
- Best for: Email as the primary revenue channel
- Watch out for: Cost rises as your audience grows

Migrating without losing segmentation
A contact export is easy. Preserving the structure that makes the list useful is the actual work, and doing it in the wrong order costs you years of accumulated signal.
Document your segments before exporting anything. Write down every audience, tag and group, what it means, and which automations depend on it. Half of them will turn out to be obsolete, which is useful to discover, and the other half must survive the move.
Export with the metadata, not just the addresses. Signup date, source, tags and consent status all need to come across. Subscription date and source in particular are what let you answer a consent enquiry later, and they are the columns people most often forget.
Rebuild tags first, then import. Create the tag structure in the new system before loading contacts, so the import maps onto it rather than producing a flat list you then have to segment by hand.
Warm up rather than switching overnight. Your new sending identity has no reputation. Send to your most engaged segment first, increase volume over two or three weeks, and keep the old platform active until the new one has completed a full cycle without incident.
Rebuild automations manually and test each one. There is no import path for sequences. Recreate them, run a test contact through every branch, and confirm the emails arrive in the right order before switching anything on for real subscribers.
Frequently asked questions
How much cheaper is a per-site plugin?
At 25,000 contacts a platform commonly costs $2,400 a year against $103 for the plugin plus modest sending. The gap widens as the list grows.
Will my site slow down with 100,000 contacts?
It can if hosting was sized for a brochure site. Contacts with activity histories are real data, so budget for adequate hosting rather than discovering the limit mid-campaign.
Does deliverability get worse?
It becomes your responsibility rather than automatically worse. Authenticate the domain, warm up gradually and process bounces automatically, and it holds up.
Can I keep my automations?
Not by import. Rebuild them manually, run a test contact through every branch, and treat the migration as the moment to delete the ones you never actually used.
Which is best for a WooCommerce store?
FunnelKit Automations if email follows the purchase lifecycle, FluentCRM if you need both commerce and general marketing on a flat price.
When should I not move?
When email is your main revenue channel and nobody wants to own deliverability, or when your team works in the platform daily and retraining costs more than the subscription.
The verdict
The whole argument is one sentence: per site, not per contact. At 25,000 contacts that is $103 a year against $2,400, for software that also sees your orders, courses and memberships without an integration.
For most sites leaving a platform: FluentCRM at $103 a year, whose tags, sequences and contact timelines make the transition feel like a move rather than a downgrade.
For sales pipelines: Groundhogg. For stores: FunnelKit Automations. Both keep the per-site pricing and specialise where a general CRM is broad.
And audit your usage before you migrate anything. A surprising number of platform subscriptions exist to send one weekly broadcast, and a free plugin replaces that entirely. Move deliberately, document your segments first, and warm up your sending rather than switching overnight.
