You have a few hundred subscribers, maybe a couple thousand. You need to send them updates, announcements, or a weekly newsletter. You’re not running a marketing agency or selling courses to 50,000 people. You just need something that works without eating your budget or requiring a marketing degree to operate.
The problem is that most email tool comparisons are written for scale you don’t have. They compare enterprise features you won’t use and ignore the constraints that actually matter when your list is small: cost per send, whether the interface feels cluttered with features you’ll never touch, and if you can get started in an afternoon instead of a week.
Here’s what actually matters when you’re under 5,000 subscribers.
The Real Cost Structure Under 5,000
Most email tools have free tiers that cap around 500-2,500 subscribers. Above that, you’re paying. The question is how much and what you’re actually getting for it.
Mailchimp remains the most recognized name. Their free tier covers 500 subscribers and 1,000 sends per month (not per day, per month total). Once you cross 500 subscribers, you’re on the Standard plan at $20/month for up to 1,500 subscribers, then $35/month for up to 3,000, and about $60/month for 5,000. These prices drift higher if you don’t prepay annually.
The interface has accumulated feature bloat over the years. You’ll see website builders, CRM features, social posting tools. If you just want to write an email and send it, there’s navigation overhead. The email builder itself is competent, but you’re paying partially for things you’re not using.
Buttondown takes the opposite approach. It’s designed specifically for newsletters, not marketing campaigns. $9/month gets you up to 1,000 subscribers, $29/month for 5,000. The interface is deliberately minimal: write in Markdown, send email. There are no drag-and-drop builders, no fancy segmentation dashboards, no A/B testing at this tier. You get deliverability, subscriber management, a simple API, and archive hosting. That’s it.
This works if you’re sending text-based updates or newsletters where the content matters more than the design. It doesn’t work if you need visual emails with multiple columns, buttons, and image layouts.
ConvertKit (now rebranded as Kit) starts free up to 10,000 subscribers, but the free tier is heavily restricted. You can’t use automated sequences, you can’t segment meaningfully, and you can’t use their visual automation builder. The Creator plan that unlocks these features costs $25/month for up to 1,000 subscribers, then $50/month for 3,000, and roughly $80/month for 5,000.
ConvertKit’s value proposition is automation and tagging. If you need behavior-based sequences (someone clicks a link, they get added to a specific follow-up series), ConvertKit makes this easier than most alternatives. But you’re paying for that sophistication even if you’re just sending a weekly update.
What You’re Really Paying For
The pricing differences reflect different priorities, not just subscriber counts.
Deliverability is table stakes. All the tools mentioned here handle this competently for small lists. Spamhaus doesn’t care about your ESP if you’re sending 2,000 emails a week to people who opted in. Problems emerge when you import sketchy lists or blast promotional content. At under 5,000 subscribers with legitimate opt-ins, deliverability is rarely your bottleneck.
Automation complexity is where the price spread matters. Mailchimp’s Standard plan gives you basic automation (welcome emails, simple triggers). ConvertKit’s entire structure assumes you want to build sequences based on behavior. Buttondown offers basic automation only through their API or webhooks, expecting you to integrate with other tools if you need complexity.
If you’re sending a weekly newsletter, you don’t need automation. If you’re nurturing leads through a content upgrade funnel, you do. Price accordingly.
Template builders vary wildly. Mailchimp offers a drag-and-drop builder with extensive layout options, though it can be finicky about mobile rendering. ConvertKit’s builder is simpler, optimized for single-column layouts that work well for content creators. Buttondown doesn’t have a visual builder at all—you’re writing HTML or Markdown.
The honest assessment: if you’re not a designer, drag-and-drop builders save time upfront but create visual inconsistency over time because it’s easy to deviate from your own patterns. Text-based approaches (Markdown or HTML templates) enforce more consistency but require comfort with code or markup.
The Underrated Options
EmailOctopus runs on Amazon SES infrastructure and passes the savings through. Free up to 2,500 subscribers, then $8/month for 5,000. The interface is clean, the builder is functional, and there’s basic automation. It’s not innovative, but it’s also not trying to be. If you need to send emails without frills or philosophy, EmailOctopus is a legitimate budget option.
The trade-off is support and ecosystem. There are fewer integrations, less community content about how to use it, and support that’s adequate but not exceptional. For straightforward sending, this doesn’t matter. If you need to troubleshoot API integrations or connect to niche tools, you’re more on your own.
Sendy is a self-hosted option that uses your own Amazon SES account. One-time payment of $69, then you pay only Amazon’s SES fees (roughly $0.10 per 1,000 emails). For 5,000 subscribers sending weekly, that’s about $2/month in sending costs.
The catch is you’re managing the hosting, updates, and technical infrastructure. You need a server (DigitalOcean droplet starts at $6/month). You’re responsible for security patches, backup, and troubleshooting. If you’re technical or want to be, this is the cheapest sustainable option. If you’re not, it’s a distraction from your actual work.
Loops is newer, targeting indie developers and product builders. $20/month for up to 2,000 contacts, $40/month for 5,000. The differentiator is that it’s built to integrate cleanly with product data—sending transactional emails, user onboarding sequences, and marketing emails from the same platform. If you’re building a SaaS product and want one tool for all email, Loops reduces integration overhead.
It’s less mature than alternatives. Fewer templates, smaller community, more frequent feature changes. You’re betting on the trajectory, not the current state.
What Nobody Tells You About List Growth
Pricing tiers create weird incentives. Once you’re at 4,800 subscribers, adding 200 more might jump you to the next tier, potentially adding $20-40/month to your costs. This creates pressure to either stop growing or aggressively monetize.
This is why pricing structure matters as much as current cost. ConvertKit’s tiers jump more sharply than Mailchimp’s gradient. EmailOctopus has gentler increases. Buttondown’s pricing is linear and predictable. If you expect to grow, model out the next two or three tiers, not just where you are today.
Most tools also charge by subscriber count, not by engaged subscribers. If half your list hasn’t opened an email in six months, you’re still paying for them. Tools like ConvertKit let you archive inactive subscribers to avoid charges. Others don’t. Cleaning your list isn’t just about deliverability; it’s cost management.
The Features You Think You Need But Probably Don’t
A/B testing sounds valuable. In practice, under 5,000 subscribers, you rarely have statistical significance unless open rate differences are dramatic. Testing subject lines with 2,000 recipients split into two groups of 1,000 won’t tell you much unless one performs wildly better.
Advanced segmentation is similar. Yes, you can create complex segments based on tags, behavior, and demographics. But if you’re sending weekly to a relatively homogeneous audience, you’re creating work without return. Segmentation matters when you have distinct audience groups with different needs, not just because the tool offers it.
Landing pages and forms are bundled into many tools. Unless they’re excellent (and most aren’t), you’re better off using dedicated tools. Mailchimp’s landing pages are functional but limited. ConvertKit’s forms are solid for simple captures. Neither replaces what you could build with Carrd, Webflow, or even a well-designed Google Form.
What Actually Matters for Small Lists
Speed to send. Can you write an email and send it in 15 minutes, or does the interface require 30 minutes of navigation and setup each time? Friction compounds weekly.
Import/export without hassle. You should be able to export your entire list with full data in minutes. Some tools make this deliberately difficult to create lock-in. Test this before committing.
Reasonable mobile rendering. Your subscribers will open emails on phones. Preview how your emails look on iOS Mail and Gmail mobile apps, not just desktop browsers.
Support quality when you need it. At this scale, you’re probably not paying for priority support. But can you get an answer to a technical question within 24 hours? Check recent reviews and support forum responsiveness.
Who Should Pick What
Choose Buttondown if: You’re sending text-based newsletters, you value simplicity over features, and you’re comfortable with Markdown or basic HTML. Best for writers, indie thinkers, and anyone who wants email to stay simple.
Choose EmailOctopus if: You need visual emails on a tight budget and don’t require advanced automation. Best for small businesses, side projects, and anyone where email is important but not central to the business model.
Choose ConvertKit if: You’re building automated sequences based on user behavior, you’re monetizing through content upgrades or courses, and the $50-80/month cost is justified by subscriber value. Best for creators, coaches, and small course sellers.
Choose Mailchimp if: You need broad integrations with other tools (Shopify, WordPress, etc.), you want one platform that handles multiple marketing channels, and you’re willing to pay for features you might grow into. Best for small retail, agencies serving clients, and businesses where email is part of a larger marketing operation.
Choose Sendy if: You’re technical, you want the lowest long-term costs, and you’re comfortable managing infrastructure. Best for developers, technical founders, and anyone running multiple projects who can amortize the setup effort.
The right answer depends less on your subscriber count and more on what you’re actually sending and how much time you want to spend managing the tool. Under 5,000 subscribers, you’re optimizing for operational simplicity and cost efficiency, not enterprise features or scale. Pick the tool that gets out of your way.
