You buy credits once, at one flat rate, and they never expire. Every AI step is charged only when it actually runs. Everything that is not AI, verifying an address and sending the mail included, costs nothing on every edition, forever.
Syntax, disposable domains, MX records, catch-all detection and an SMTP probe that sends nothing. Built in, not resold, so there is no per-address fee and no verification plan to buy.
Through your own mailbox, over plain SMTP. No relay, no shared sending domain, no warm-up network to rent. Connect as many mailboxes as you like: we do not count them and we do not charge for them.
Replies land in the mailbox you already read. Nothing is charged for a reply arriving; only the agent that reads it and decides what happens next costs a credit, and it is one.
Invite your whole team. Nobody is counted, and there is no plan that unlocks them.
Hosted and backed up for you, AI included and metered in credits at the rate above. Starts with a knowledge base that is already big and keeps growing.
Start freeDocker, five minutes, your own AI provider key, which you pay that provider directly and nothing to us. The same code with no feature gate: nothing removed, nothing metered, unlimited mailboxes and seats, and your data never leaves your machine.
Read the install guideWe are comparing pricing models here, not naming anyone: their prices change every quarter, and the shape of the deal is what actually costs you money.
No. They sit on your balance until you spend them. There is no monthly reset and no use-it-or-lose-it.
The agents stop and tell you. Nothing is deleted, nothing is cancelled, and no card is charged that you did not ask us to charge. Auto top-up is off until you turn it on, and then it only fires at the threshold and the amount you set, under a monthly ceiling you choose.
5,000 credits at signup, no card. A trial runs one project and stops at 500 leads found. Both limits lift the first time you top up.
Neither. Invite the whole team and connect every mailbox you have; nothing about that changes what you pay.
There is no bill. There is a balance you topped up on purpose.
There is not one. Same repository, same code, AGPL-3.0, no feature gate. You bring your own AI provider key and pay that provider directly.
Yes. It is the same codebase: Docker, five minutes, your own key. Nothing is missing.
5,000 free credits, no card. Spend nothing more until you decide to.
