A: Hi,

Thank you for your question!

The email credits are part of the lifetime deal - you get them once, and they’re yours to use anytime. They are not renewed monthly. However, they do not expire - you can use them at your own pace until they are fully consumed.

Once your email credits are used up, you can continue sending emails at a postpaid rate of $0.40 per 1,000 emails. If you don’t send any emails, there will be no charges. No monthly/annual subscription is needed. Just pay as you go.

Additionally, yes - you can connect multiple domains and use them as sender email domains.
