The True Cost of Email Marketing at Scale (2026)
Email marketing pricing looks cheap when your list is small. The trouble is the shape of the curve: with every hosted platform, the bill rises with your subscriber count and recurs every month, forever. Self-hosted software inverts that — you pay once, and your ongoing cost is mostly just sending.
This post walks through what email marketing actually costs as a list grows from 1,000 to 100,000 subscribers, and why the gap widens the more successful you get.
A note on numbers: the figures below are approximate 2026 list prices used to illustrate the shape of each pricing model. Plans and tiers change constantly — always check current pricing, and use our savings calculator for your exact situation.
The two pricing models
There are really only two models in email:
- Per-subscriber subscriptions (Mailchimp, Beehiiv, ConvertKit/Kit, and most SaaS). You pay a monthly fee that steps up as your list grows. You’re renting access; stop paying and you lose the platform.
- Buy-once, self-hosted (Broadcast and other self-hosted tools). You pay a one-time license and run the software on your own server. Your only ongoing costs are cheap hosting and your email provider’s per-send rate.
The first model is priced on how many people you could email. The second is priced on how many you actually email. That difference is everything.
Monthly cost as your list grows
Approximate monthly cost on each platform’s mainstream paid tier:
| Subscribers | Mailchimp (Standard) | Beehiiv | ConvertKit / Kit | Broadcast (self-hosted) |
|---|---|---|---|---|
| 1,000 | ~$25/mo | $0–49/mo | ~$25/mo | ~$11/mo |
| 10,000 | ~$100/mo | ~$84/mo | ~$100/mo | ~$14/mo |
| 50,000 | ~$350/mo | ~$130/mo | ~$379/mo | ~$30/mo |
| 100,000 | ~$550/mo | ~$190/mo | ~$679/mo | ~$55/mo |
For Broadcast, “monthly cost” is just hosting (~$5–20/mo) plus sending through Amazon SES at about $0.10 per 1,000 emails. Send a weekly newsletter to 100,000 people and that’s roughly 400,000 emails a month — about $40 in sending, plus hosting. There’s no charge for the subscribers themselves.
Three-year total cost of ownership
Monthly numbers hide the real story. Email lists are long-lived, so the honest comparison is multi-year. Here’s the approximate three-year total at each size, including Broadcast’s one-time $250 license:
| Subscribers | Mailchimp | Beehiiv | ConvertKit / Kit | Broadcast |
|---|---|---|---|---|
| 1,000 | ~$900 | ~$900 | ~$900 | ~$650 |
| 10,000 | ~$3,600 | ~$3,000 | ~$3,600 | ~$750 |
| 50,000 | ~$12,600 | ~$4,700 | ~$13,600 | ~$1,330 |
| 100,000 | ~$19,800 | ~$6,800 | ~$24,400 | ~$2,230 |
At 1,000 subscribers the difference is real but modest. At 100,000, a per-subscriber SaaS can cost ten times what a self-hosted setup does over three years — and the gap keeps compounding in year four and beyond, because you keep paying and the self-hoster largely doesn’t.
Why per-subscriber pricing punishes growth
The uncomfortable thing about per-subscriber pricing is that it charges you for potential, not value. A subscriber who never opens an email costs exactly as much as your best customer. As your list grows:
- Your bill rises whether or not the new subscribers convert.
- You’re nudged toward pruning engaged-but-quiet contacts purely to manage cost.
- Your most successful months — when you’re growing fastest — are also when your costs spike hardest.
Self-hosting breaks that link. Adding 10,000 subscribers to a self-hosted platform costs nothing extra to store; you only pay the few dollars it takes to email them.
When SaaS still makes sense
This isn’t a claim that self-hosting always wins. Hosted platforms are the better choice when:
- Your list is small and likely to stay that way (the savings don’t justify any setup effort).
- You depend on platform-specific features — Beehiiv’s ad network, ConvertKit’s creator commerce — that a self-hosted tool doesn’t replicate.
- You can’t or won’t run a server, and the time cost of self-hosting outweighs the money saved.
For everyone else — especially technical founders, agencies, and anyone whose list is growing — the math increasingly favors owning your platform. See the honest version of that trade-off in our self-hosted email marketing comparison.

Switching is mostly a matter of exporting your list and rebuilding a few flows. We’ve written step-by-step guides:

The tables above are illustrative. Your real cost depends on your list size, how often you send, and which provider you connect. Plug in your numbers with the savings calculator to see what self-hosting would cost you specifically — and what you’d save over three years.
Broadcast is a one-time $250 license: unlimited subscribers, your server, your data. See pricing or try the live sandbox.
