Hive's email pricing is pay-as-you-go.
The number of emails sent in a particular month dictates the price per email.
For example, if you send 20,000 emails next month, you'll be billed $50 for the month (20,000 * $0.025). This fee is added to your monthly subscription fee.
If you're consistently sending a high volume of emails, get in touch with us and we'd be happy to offer a preferable flat monthly rate! Shoot us an email at firstname.lastname@example.org anytime.
