Billing questions.
Need an invoice or a custom volume? Contact billing.
Do credits expire?
Paid credits never expire. The 20 free daily verification credits reset every day at 00:00 UTC and are used before your paid credits.
What counts as one credit?
One verification credit checks one email address. One email credit sends one email to one recipient through the transactional API or SMTP relay. Duplicates in a list are removed before charging.
Am I charged for unknown results or failed sends?
No. Power-mode checks that end as unknown are refunded automatically, and emails that are suppressed, invalid or fail to send are returned in the same request.
Can I get a refund?
Unused credits bought in the last 14 days can be refunded. The refund policy explains how.
Do you offer monthly plans?
Not today. Most customers prefer packs because nothing is wasted in a quiet month. If you need a fixed monthly volume with an invoice, talk to us.
