Best Email Marketing for Creators: 6 Tools Priced by List Size

Every “best email tool for creators” list ends the same way: Kit is number one, beehiiv is for newsletters, and the prices are whatever the writer copied last year. If you are picking a platform this week, you need two things those lists skip. One is what six tools cost at real list sizes, pulled from their own pricing pages on September 7, 2026. The other is the Gmail and Yahoo sending rules that decide whether your emails arrive at all.

One disclosure first. I grew a YouTube channel past 130,000 subscribers as a one-person operation and learned what a rented audience is worth, but I do not run any of these six tools at scale today. Every tool claim below is third person, taken from the vendor’s pricing page or help center, never from “I tested”. The first person is reserved for why a creator needs a list and how I would choose one for a channel like mine.

Why an owned list is the only asset that keeps working

Two things taught me this, and both were on my own channel and my own product. The first was YouTube: growing a channel past 130,000 subscribers alone means you watch the algorithm decide, week after week, who gets to see your work. Reach you rent behaves like a treadmill. Step off and it stops.

The second was an ebook. I built one, sold it with paid ads, and the sales were real for as long as the ads ran. When I stopped the ads, the ebook sales stopped with them, and I shut the product down rather than keep feeding the machine. I wrote up the whole failure in how I’d sell an ebook without ads today. The lesson that stuck: I had ebook buyers, but no way to reach them again, so every sale was a first sale.

An email list is the fix for both problems because it is the one audience asset you can pick up and carry out the door. “Owned” is a technical claim, not a feeling: you can export the subscriber file as a CSV and import it somewhere else. Every tool in this article lets you do that. That is why starting on a free plan is safe: the decision is reversible.

What six tools cost at 1,000, 5,000 and 10,000 subscribers (checked September 7, 2026)

Prices below come from each vendor’s own pricing page, help center, or comparison page, collected on September 7, 2026. Where a vendor only shows a figure through an interactive calculator and nothing in the page text, the cell says “calculator only” rather than a number copied from somebody else’s blog. Monthly billing unless noted. The two right-hand columns matter more than the sticker price.

How to read this. The cheapest column is not the point; the billing basis is. Mailchimp is the only tool here that keeps charging you for people who have already left, unless you go in and archive them. MailerLite counts anyone who was active at any point in the billing cycle, so deleting people mid-month does not lower that month’s bill. Kit and beehiiv bill on active subscribers and auto-upgrade you the moment you cross a tier; Kit’s help center walks through a 1,001st subscriber triggering a prorated jump from the $39 tier to the $59 tier.

The “calculator only” cells are deliberate. Kit’s pricing page shows the Creator plan at 1,000 subscribers with a slider that runs to 500,000, and its help center adds the 3,000 tier at $59; beyond that, the number only appears when you move the slider. Same for beehiiv and Mailchimp. Roundups that print a Kit price at 5,000 are reading the slider on the day they looked, or reading each other. Move the slider yourself before you decide; it takes thirty seconds.

Which one, if you are a…

This is a decision list, not a ranking. Each pick is tied to a cell in the table above and to what the vendor’s own pages say the tool does.

1. YouTuber or video-first creator, list as a backstop. Start on Kit’s free plan. Ten thousand subscribers with unlimited sends and landing pages costs nothing, and a channel that converts even one viewer in a hundred takes a long time to fill that. The trade-off is one basic automation and Kit branding until you pay. If your videos are your product and the list is a backstop, that is fine for a year or more. When you do pay, run the slider first: the jump from free to the paid tier happens at 10,001 subscribers, which is when the list is finally big enough to matter.
2. Newsletter-first writer whose emails are the product. beehiiv if you plan to sell sponsorships or paid tiers and want 0% taken from subscription revenue; Substack if you want zero setup and accept 10% plus Stripe on whatever readers pay. Free readers cost you nothing on either. The fork is simple: at $10 a month per paid reader, Substack’s 10% passes beehiiv’s $49 monthly Scale fee at about 50 paying readers. Below that, Substack is cheaper. Above it, beehiiv is.
3. Seller of digital products or courses. Kit or MailerLite, and the choice is a fee question. Kit charges 3.5% + $0.30 per sale, which it says includes card processing. MailerLite takes 0% commission on digital products, with Stripe’s fee on top. Kit gives you more automation depth for launch sequences on its paid plan; MailerLite’s Comfort plan caps you at 50 active automations and a send limit of 10x your tier ceiling, which a launch week can burn through. Selling ebooks, I would want the send cap gone before the launch, not during it.
4. App or software maker. Buttondown or MailerLite. App makers usually already have a website and a way to take payment, so the email tool’s job is transactional-adjacent: a launch list, release notes, a waitlist. Buttondown is $9 a month at 1,000 subscribers and $29 at 5,000, bills active subscribers only, and treats tagging, analytics and automations as add-ons at $9 or $29 each. If you need visual automations and forms without add-on math, MailerLite’s Power plan at $39 for 1,000 is the simpler bill. Skip Substack here; it is built around a publication, not a product.
5. Anyone who refuses to pay before revenue exists. Kit’s free plan to 10,000 or beehiiv’s to 2,500. Both let you export the CSV later. Do not start on Mailchimp’s free plan: 250 contacts and 500 sends a month is a week of growth for an active channel, and once you pay, you pay for unsubscribes too.

The six tools, one honest paragraph each

None of this is from hands-on testing. It is what the pricing pages and help centers say, read closely.

Kit (formerly ConvertKit)

The free Newsletter plan is the most generous starting point in this list: up to 10,000 active, unique subscribers, unlimited sends, forms, landing pages, digital products and paid subscriptions, plus A/B testing on subject lines. What it withholds is the machinery: one basic visual automation with one sequence, no integrations, no rules, no RSS campaigns, and a Kit-managed slot in your recommendations. The Creator plan removes those limits at $39 a month for 1,000 subscribers, or $33 a month billed annually, and Creator Pro is $79, or $66 annually, adding subscriber scoring and deliverability reporting. Kit’s help center is clear that billing follows confirmed subscribers and that crossing a tier upgrades you automatically with proration. The weak spot for a creator is cost growth: the 1,000-to-3,000 step alone is $39 to $59, and nothing on the static page tells you the rest.

beehiiv

beehiiv’s free Launch plan runs to 2,500 subscribers with unlimited sends and a website. The things newsletter operators actually want, paid subscriptions, the ad network and referrals, live behind the Scale plan at $49 a month, or $43 billed annually; Max is $109, or $96 annually. The pitch that holds up on the pricing page is the 0% take on paid subscription revenue, with only Stripe’s 2.9% + $0.30 coming off. beehiiv’s own comparison page against Kit lists $109 at up to 10,000 subscribers and $329 at up to 100,000, though it does not say whether those are monthly or annual figures. Its help center defines an active subscriber as one who has not unsubscribed or been marked inactive, and that is what your tier is based on. The trade-off is automation depth: this is a publishing tool first.

MailerLite

MailerLite renamed its paid plans in 2026: Growing Business became Comfort and Advanced became Power. The free plan is 250 subscribers and 2,500 emails a month. Comfort starts at $12 a month at the 500-subscriber tier and comes with a send cap of ten times your tier ceiling, up to 50 active automations, 10 forms, 10 landing pages and websites combined, and 5 digital products. Power lifts the caps, and MailerLite’s own comparison pages price it at $39 for 1,000 subscribers, $69 for 5,000, $129 for 10,000 and $239 for 25,000, with 10% off for annual billing. Billing counts active subscribers only, but cumulatively across the cycle. The creator-relevant catch is that the 250-subscriber free tier is small, so this is a tool you pay for early and cheaply rather than one you ride for free.

Mailchimp

Mailchimp is here because people search for it, not because it fits creators. The free plan is 250 contacts and 500 sends a month with a 250-a-day cap. Essentials shows $13 a month and Standard $20 a month for the first 12 months at the entry contact tier, and both carry monthly send limits of 10x and 12x your contact limit, with overage charges when you exceed either. The line that should decide it for a creator is in the help center: subscribed, unsubscribed and non-subscribed contacts all count toward your bill, and only archived, cleaned and deleted contacts do not. Every other tool in this table stops charging you when someone leaves.

Substack

Substack is free to publish at any list size. If you turn on paid subscriptions, Substack takes 10% of each transaction and Stripe takes 2.9% + $0.30, plus a 0.7% billing fee for subscribers who signed up after July 2024. Your subscriber list, posts and statistics can be exported from the publication settings as a zip file, so the lock-in argument is weaker than it sounds. What you give up is the toolset: no tags-and-automation model, and a fee that scales with your revenue instead of your list. For a writer with 300 free readers and no plans to sell anything else, that trade is the right one.

Buttondown

Buttondown is the minimal option, and its pricing is the most legible: free for 100 subscribers, then $9 a month at 1,000, $29 at 5,000, $79 at 10,000 and $139 at 20,000, billed on active subscribers only. The base plan includes the editor, custom domain sending and hosted archives; tagging, paid subscriptions, analytics and RSS-to-email are $9 add-ons each, and automations, multiple newsletters and custom-domain archives are $29 each. That add-on model is the trade-off. A creator who needs tags, automations and paid subscriptions is at $47 a month before the subscriber tier, which is beehiiv territory. A developer who needs one list and an API is not.

What Gmail and Yahoo require before your emails land

This is the section every roundup replaces with “authenticate your domain”. The actual rules are public, short, and decide more about your results than the tool you pick.

Google publishes two tiers of requirements. Everyone sending to Gmail must authenticate with SPF or DKIM, have valid forward and reverse DNS (PTR) records for the sending domain or IP, send over TLS, format messages to RFC 5322, and keep the spam rate reported in Postmaster Tools below 0.3%. Senders at roughly 5,000 or more messages a day to personal Gmail accounts, counted across the whole primary domain including subdomains, face four more rules. Both SPF and DKIM. A DMARC record, where a policy of none is allowed. The visible From domain aligned with the SPF or DKIM domain. And one-click unsubscribe in marketing messages, with a visible unsubscribe link in the body.

Google’s FAQ adds three details. Bulk-sender status does not expire once earned. Unsubscribe requests must be honored within 48 hours. And senders should aim below 0.1% spam and never touch 0.3%, because above that line Google stops offering mitigation until you stay under it for seven straight days.

Yahoo’s list is nearly identical. SPF or DKIM for everyone. Both SPF and DKIM plus a DMARC policy of at least p=none for bulk senders. A working List-Unsubscribe header with one-click support, with the RFC 8058 POST method recommended. Unsubscribes honored within two days, and a spam rate under 0.3%.

What this means in practice splits into two lists. The platform handles the parts that live on its servers: TLS, PTR records for its sending IPs, the List-Unsubscribe headers, and the unsubscribe processing. You handle the parts that live in your DNS: SPF and DKIM records for a domain you own, and a DMARC record. If you send from a free Gmail or Yahoo address as the From, you fail the alignment rule the day you become a bulk sender, and the fix is a custom sending domain, which every tool in this article supports. Do it before the first send, not at 4,999 subscribers.

The one-click unsubscribe rule also quietly settles a design argument. Burying the unsubscribe link no longer protects your list; it raises the spam rate that Google and Yahoo actually measure.

What actually moves when you switch tools

Every tool here moves a list as a CSV. Kit imports CSV files and lets you map columns to custom fields and a comma-separated tags column, and exports first name, email, created date, status, tags, location and custom fields. beehiiv exports a quick CSV of email, status and tier, or a full CSV with custom fields and statistics; the download link lasts 24 hours. MailerLite imports CSV or TXT files, pasted Excel columns, or directly from a Mailchimp account, and requires that everyone on the file consented to hear from you. Mailchimp exports a zip of separate CSVs for subscribed, unsubscribed, non-subscribed and cleaned contacts, with a tags field included. Substack exports posts, subscriber list and statistics as a zip from the publication settings.

What does not move: your automations (rebuild them), your sending reputation on the old provider’s shared domain (warm the new setup up with smaller sends), and your archive URLs unless they were on a domain you own. That last one is why the custom domain from the previous section pays twice.

Migration cost, then, is mostly your time plus the risk of a deliverability dip while the new setup earns trust. Budget an afternoon for the export and import and a couple of weeks of smaller, steadier sends afterward.

How I’d choose, and the one thing to do this week

If I were starting a list beside a YouTube channel today, I would take Kit’s free plan for the 10,000-subscriber runway, put it on a domain I own, and revisit the choice when the slider says the paid tier is due. If the emails themselves were the product, I would take beehiiv once paying readers passed roughly 50 and Substack before that. If I were selling an ebook again, I would want the send cap gone before the launch week, because the last time sales depended on a channel I did not own, they stopped the day I stopped paying for it.

Whichever you pick, do this before anything else: register or reuse a domain you own, add its SPF, DKIM and DMARC records in the tool’s domain settings, and send your first email from that address. Everything else in this article is reversible. A list that lands in spam is not. Once it is sending, the list slots into the rest of a one-person stack the same way the tools in my AI tool short list do: one job each, and the rest of the tool-stack stays small.
