Are there per-message costs?

No, we do not charge per message. Our pricing is based on a flat-rate billing plan, allowing you to send messages without worrying about additional per-message fees.

Is there a daily or monthly message limit?

There is no message quota and no per-message fee. Send protection paces new contacts: by default 20 new conversations an hour and 60 a day per number, and you can switch it off per instance. We recommend a minimum of 15 seconds between messages to avoid account bans.

Are there per-user fees or seat limits?

No. We bill only per instance — there are no per-user fees or seat limits. Your API token can be used by any number of applications or developers you work with.

Is there a limit to the number of instances I can have?

No. With a single billing plan, you can have as many instances as you need. There is no need to subscribe to multiple plans to increase your instance limit.

What is the recommended message sending frequency to avoid bans?

To minimize the risk of bans, we advise maintaining a minimum interval of 15 seconds between messages for each instance.

What happens to my instances when I unsubscribe from a billing plan?

We retain your instances until your current billing period expires. After expiration, we only remove instances if they exceed your new plan limit, starting with the most recently created ones. We'll notify you by email about any changes when you unsubscribe.

Are refunds available?

We don't offer refunds, but our support team is ready to assist you with any issues or requests you may have.
