MailBluster has two pricing plans: Free Forever and Unlimited Sending. The Free Forever plan will allow you to send 62,000 emails per month with MailBluster branding on all the outgoing emails and unsubscribe pages. Also you do not need to add any Billing Card to use the free plan. And for the Unlimited Sending plan, you’ll be charged $0.20 for sending every 1000 mails from your MailBluster account. Also there is an added advantage that you can optionally disable MailBluster’s branding on emails and unsubscribe pages. You just need to add a Billing Card (must be Stripe supported) in MailBluster.
