One free plugin. One paid add-on.
The free half is complete and stays complete. The paid half exists because delivery cannot be fixed from inside a WordPress install.

Your first year is $69. It renews at $99. If the price ever changes you get 60 days’ notice, and a refund for any time you have not used.
If the plugin is not published on WordPress.org by 31 October 2026, every early-access payment is refunded automatically. You do not have to ask.
Prices in USD. Taxes handled at checkout. Paid through Polar, our merchant of record.
Four things we will not do to you.
No lifetime licence
Ever. A lifetime price is paid for by the customers who arrive later, and it is the single most reliable way small software vendors disappear.
No features held hostage
Nothing in the free plugin is switched off waiting for a payment. What you pay for is our sending infrastructure — a thing we run, not a lock we open.
No silent price change
Your first year is $69. It renews at $99. If the price ever changes you get 60 days’ notice, and a refund for any time you have not used. We are not going to promise a price is frozen for years — this company cannot underwrite that, and a promise we cannot keep is worth less than no promise.
No dark pattern to cancel
Cancel in the billing portal in one click. The free plugin keeps running on your own mail afterwards. Thirty days to change your mind. No reason needed, full refund.

Get the early-access price
Join the list and you will get the early-access link the day the add-on opens — at the founding price, locked for as long as you renew.
