You’ve hit 25,000 subscribers. Congratulations — that’s a real audience. It’s also the exact list size where email marketing pricing gets weird and the “which tool is cheapest?” question stops having a simple answer.
At 1,000 subscribers, everyone’s cheap. At 100,000, everyone’s expensive. But 25,000 is the inflection point where MailerLite’s flat-ish pricing curve starts bending upward, Kit is charging real money, ActiveCampaign genuinely competes on value if you have a sales pipeline, and Beehiiv can actually pay for itself if you’re monetizing.
This article shows you the real 12-month cost of email marketing at 25,000 subscribers across every major tool — with the actual plan tiers, the annual math, and honest recommendations for who should pick which.
The 12-Month Cost at 25,000 Subscribers
Here’s what a year on each platform actually costs at exactly 25,000 subscribers, based on their published 2026 pricing. All figures assume monthly billing at the plan tier required to support that list size.
| Tool | Plan tier at 25K subs | Monthly cost | 12-month cost |
|---|---|---|---|
| MailerLite | Advanced | ~$75 | ~$900 |
| Beehiiv | Scale | ~$84 | ~$1,008 |
| GetResponse | Marketing Automation | ~$120 | ~$1,440 |
| Kit (formerly ConvertKit) | Creator Pro | ~$166 | ~$1,992 |
| ActiveCampaign | Plus | ~$187 | ~$2,244 |
| Mailchimp | Standard | ~$195 | ~$2,340 |
That’s a $1,440 gap between the cheapest option (MailerLite at $900) and the most expensive (Mailchimp at $2,340) — for what is, functionally, similar core email-sending capability at this list size. Over five years that’s $7,200. That’s a used car.
But price isn’t the whole story. Some of these tools do things at 25K subs that the others simply can’t, and some of them start paying for themselves if you have the right business model. Below is who should pick which — and why the “cheapest” isn’t always the right answer.
MailerLite at 25K Subs: Still the Best Default for Most
At 25,000 subscribers, MailerLite’s Advanced plan runs about $75/month. That includes unlimited emails, marketing automation, dynamic content, A/B testing, landing pages, and multi-user access. For most creators and small businesses at this size, that’s more than enough.
Pick MailerLite at 25K if:
- You’re primarily sending newsletters, product updates, or transactional-style emails
- You don’t need a CRM or sales pipeline
- Deliverability and simplicity matter more than feature depth
- You want the option to add landing pages without paying extra
Where MailerLite falls short at 25K:
- Automation logic is capable but not as sophisticated as ActiveCampaign or GetResponse
- No native ad network or newsletter-monetization features (which is where Beehiiv wins for a subset of users)
- No webinar or funnel tools baked in (that’s GetResponse territory)
For a straightforward “email a real audience” use case at 25K subs, MailerLite is still the correct default. The math just doesn’t beat it for content creators, bloggers, or small businesses without complex needs.
Beehiiv at 25K Subs: Where It Actually Pays for Itself
Beehiiv’s Scale plan at 25,000 subscribers runs about $84/month annually billed. On raw cost, that’s more expensive than MailerLite. But Beehiiv is the only tool on this list where the platform can pay for itself through built-in monetization — and at 25K subs, that math is worth doing.
A 25K-subscriber newsletter with a 40% open rate and even modest ad network revenue can pull in $500-$2,000+/month through Beehiiv’s native ad network — well above the $84 monthly cost. Paid subscriptions and boosts (paid recommendations) add more.
Pick Beehiiv at 25K if:
- Your newsletter is the product — not the funnel for something else
- You want to monetize through ads, paid subscriptions, or sponsorships
- You value referral rewards and boosts (Beehiiv’s list-growth tools)
- You’re already on Substack and paying their 10% subscription fee — see my Substack to Beehiiv migration guide
Where Beehiiv falls short at 25K:
- Not built for transactional or e-commerce email flows
- No CRM, no sales pipeline features
- Deliverability tools are solid but younger than MailerLite’s decade+ track record
Newsletters that make money through content are Beehiiv’s sweet spot. If that’s your model, this is the correct choice at 25K subs.
GetResponse at 25K Subs: Best for All-in-One Marketing
GetResponse’s Marketing Automation plan runs about $120/month at 25,000 subscribers. It’s not cheap. But it includes things the tools below it either don’t have or charge separately for: webinars, sales funnels, landing pages, marketing automation, e-commerce integrations, and paid ad tools.
For a small business that would otherwise be paying $50/mo for a webinar tool, $30/mo for landing pages, $40/mo for a course platform, and $50/mo for email marketing — GetResponse consolidates all of that into one bill at $120/mo. The real comparison isn’t $120 vs $75; it’s $120 vs $170+ across multiple tools.
Pick GetResponse at 25K if:
- You run webinars, launch courses, or need funnels
- You want e-commerce integrations built in
- You’re currently paying for 3+ separate marketing tools and want to consolidate
- You value marketing automation but ActiveCampaign feels like overkill
For a straight-up email newsletter, GetResponse is overpaying. For a small business marketing operation, it’s often the correct consolidation move.

Kit at 25K Subs: The Creator Premium
Kit’s Creator Pro plan lands around $166/month at 25,000 subscribers. That’s roughly double MailerLite for capabilities that overlap significantly. What you’re paying for at that premium: Kit’s creator-specific features (paid tip jars, membership products, community integrations) and a brand that’s synonymous with the creator economy.
If you’re a solo creator selling digital products, running a community, or leaning heavily on Kit’s ecosystem — it’s defensible. If you’re a business at 25K subs sending regular emails, the premium isn’t earning its keep.
Read my full Kit review for the depth on this one — it’s a good tool that costs a lot more than most of its alternatives, and whether that’s worth it depends heavily on how deep you’re going into their creator features.
ActiveCampaign at 25K Subs: When the CRM Actually Pays Off
ActiveCampaign’s Plus plan hits about $187/month at 25,000 subscribers. It’s the second most expensive tool on this list, but at 25K subs you finally get something the cheaper tools genuinely can’t match: a real CRM with sales pipelines, lead scoring, and automation logic that goes much deeper than “if opened → send” branches.
The question is whether you actually need it. See my honest ActiveCampaign review for the full pitch, but at 25K subs specifically, it’s defensible if:
- You’re running a B2B sales operation with actual account tracking
- You need conditional automation logic (multiple branches, wait steps, tag manipulation, etc.)
- You’d otherwise pay $100+/mo for a separate CRM like HubSpot or Salesforce
- Your email marketing feeds directly into a sales pipeline that a human closes
If you’re just sending newsletters, ActiveCampaign at $187/mo is Ferrari-money for grocery-store driving.
Mailchimp at 25K Subs: Almost Never the Right Answer Anymore
Mailchimp’s Standard plan at 25,000 subscribers runs about $195/month. It’s the most expensive option on this list, and honestly, the hardest to justify in 2026. Once Mailchimp’s brand recognition and legacy weight were worth paying for. Not anymore.
Deliverability is competitive but not category-leading. Automation logic is fine but not exceptional. The interface is showing its age. The pricing has drifted up steadily while competitors have added features. If you’re already on Mailchimp at 25K subs, honestly, the smart move is to test one of the cheaper options for a month and see if you notice a difference. Most people don’t.
What About Migration Costs?
At 25K subscribers, “just switch tools” isn’t as painless as it is at 500 subs. You need to think about:
- List export/import time. 15-30 minutes on any of these platforms. Not a real barrier.
- Warming up sender reputation. New sending domain = you start small and build up. Plan on 30-60 days of dialed-back sending volume.
- Rebuilding automations. This is the real cost. If you have complex automations, plan on 1-3 days of rebuild time on the new platform.
- Signup form and integration updates. Every embedded form, every third-party integration, needs to be repointed. Half a day of work.
- Announcing the change to subscribers. Expect 5-15% list churn as people re-authorize. This is normal and, honestly, healthy list hygiene.
Total realistic migration cost at 25K: 3-7 days of active work spread over a month. Payback period on cost savings alone: usually 3-6 months if you’re moving from a premium tool to MailerLite or Beehiiv.
The Bottom Line at 25,000 Subscribers
Three real answers depending on what you’re actually building:
Sending newsletters or basic email marketing → MailerLite
$900/year, unlimited emails, everything you need, nothing you don’t. This is the correct answer for the majority of readers at 25K subs.

Running a newsletter as a business → Beehiiv
$1,008/year, plus the native monetization stack (ads, paid subscriptions, boosts, referrals) that can more than cover the cost. The right answer if newsletters are the product, not the marketing channel.

Small business consolidating tools → GetResponse
$1,440/year gets you email marketing, marketing automation, landing pages, webinars, and funnels in one bill. If you’re already spending on three or more marketing tools, this consolidates and usually saves money.

Email Marketing Cost at 25,000 Subscribers FAQ
What is the cheapest email marketing tool at 25,000 subscribers?
MailerLite’s Advanced plan at approximately $75/month ($900/year) is the cheapest full-featured option at 25K subscribers.
Is MailerLite good at 25,000 subscribers?
Yes — for most use cases. MailerLite handles 25K subs cleanly with automations, landing pages, A/B testing, and unlimited emails on the Advanced plan. Where it falls short is CRM depth and newsletter-specific monetization tools, which are better on ActiveCampaign and Beehiiv respectively.
When does Beehiiv become cheaper than Substack for paid newsletters?
Around 100-200 paid subscribers, depending on subscription price. At 25K total subscribers with a small paid segment, Beehiiv is dramatically cheaper than Substack’s 10% forever cut on subscription revenue.
Is it worth switching email tools at 25,000 subscribers?
If you’re currently overpaying by $50-100/month at 25K subs (which is common if you’re on Mailchimp, Kit, or ActiveCampaign without needing their specific features), the migration payback period is typically 3-6 months. Yes, it’s worth it.
Do I need marketing automation at 25,000 subscribers?
Yes, but you don’t need premium automation. Basic automation (welcome sequences, tag-based sends, re-engagement flows) is included on MailerLite Advanced and every tool on this list. Premium automation (conditional branching, lead scoring, CRM integrations) is only worth paying for at 25K subs if you have a defined sales process.

Whatever you pick, at 25K subs the important thing is committing. Every month you stay on the wrong tool is a month of overpaying and, in some cases, leaving revenue on the table.
