New accounts get a 14-day trial after email confirmation: 100 credits and 300 campaign emails, no card and no automatic subscription; when it ends, campaigns pause and unused trial credits expire until a plan or pay-as-you-go credits are added. The app, REST API, CLI and MCP share the same account and balance; connecting another client or creating an API key does not add a second grant. Existing balances and subscriptions are unchanged.
- Granted once per account and once per mailbox (plus-addressing and dot variants count as the same mailbox).
- Disposable email domains don't qualify.
- When it is used up, pay-as-you-go credits (from $17.50) or a plan take over. Campaigns need a plan.
Search, counts and masked previews do not deduct credits. Account permissions and rate limits still apply.
