Your list grew. Your bill shouldn't.
Mailchimp charges you for growing. Senderkit charges you for sending.
Mailchimp's pricing starts at $13/mo and climbs fast — every new subscriber raises your bill, even if you never email them. Senderkit keeps your contacts unlimited on every plan and only charges when you actually press send.

Why teams start looking elsewhere
Three bills that climb faster than your open rate.
Per-contact pricing
Mailchimp's Standard plan scales with list size. Get to 10K contacts and you're at $100/mo. 50K contacts? Over $350/mo. Even if those contacts never open an email.
Inactive contacts still cost you
Archived and unsubscribed contacts count against your tier. You end up constantly pruning your list just to keep the bill down.
Transactional is a separate product
Want password resets or order confirmations? That's Mandrill — another paid add-on with its own billing.
What changes on day one
Same audience. Different economics.
Unlimited subscribers, always
500 or 500,000 contacts — the price is the same. You only pay for emails that leave the building.
Templates from Cursor / VS Code
Skip the sluggish drag-and-drop builder. Ask your AI for a launch email — it writes MJML, compiles, and saves to Senderkit in seconds.
API + transactional included
Every plan, including free, ships with a full REST API. Send transactional and marketing from the same stack, under the same bill.
