For creators who
read the fine print.
ConvertKit (now 'Kit') is excellent for creators. But its per-subscriber pricing climbs to ~$679/mo at 50k subscribers. SES Mailbox does the core job — campaigns, automations, tags — for a flat $9.99/mo on AWS SES.
ConvertKit (rebranded Kit) built its name on creator email — tagging, visual sequences, landing pages, and a Creator Network. It's a genuinely good product. The catch is the same one every per-subscriber tool has: the bill grows with your audience, whether or not those subscribers ever open an email.
SES Mailbox is a ConvertKit alternative that sends through Amazon SES at a flat $9.99/mo plus $0.10 per 1,000 emails. You keep the automations, tags, segments, and signup forms — and your margin grows with your list instead of shrinking. Here's the honest, line-by-line comparison, including what ConvertKit still does better.
Flat beats per-subscriber.

ConvertKit switching FAQ
The questions creators ask before moving.
Is SES Mailbox a good ConvertKit alternative for creators?
Yes, if your priority is sending newsletters and campaigns at the lowest cost. You get subscriber tags, dynamic segments, visual automations, signup forms, and analytics — about $15/mo at 50k subscribers versus ConvertKit's ~$679/mo. ConvertKit still leads on landing pages, paid newsletters, and its Creator Network.
How much does ConvertKit cost in 2026?
ConvertKit (Kit) prices by subscriber count — roughly $15/mo at 1k, ~$66/mo at 5k, ~$100/mo at 10k, and several hundred per month past 25k. There's a free plan up to 10,000 subscribers with limited features. Pricing shifts, so check kit.com.
Can I move my ConvertKit subscribers over?
Yes. Export your subscribers (with tags) as a CSV and import them into SES Mailbox with field mapping — your tags become targetable segments. Most creators finish in under 30 minutes.
What does ConvertKit do that SES Mailbox doesn't?
Landing pages, paid newsletters and digital-product commerce, the Creator Network, and A/B testing on broadcasts. We focus on the cheapest, most deliverable way to send creator email on AWS SES. For newsletters specifically, see SES Mailbox for newsletters.
Will my newsletter still hit the inbox on AWS SES?
Usually better — you send from your own AWS SES account and verified domain, with SPF/DKIM/DMARC checks and automatic bounce/complaint suppression, instead of a shared managed pool.
Does SES Mailbox have a free plan?
Yes — free forever, no credit card: unlimited subscribers and one campaign per month. ConvertKit's free plan caps subscribers at 10k; ours caps campaign frequency instead.
