Pricing plans are based on how many unique contacts you want to email each month (see active contacts), and the number of total emails you want to send.
Subscriptions begin from 301 contacts/month or from 3001 emails/month, whichever occurs first. There's always a free option with Carts Guru where you can market to a limited number of contacts.
SMS is paid per use and depends on the recipient's country. You can view our pricing plans and SMS pricing here.
