Plunk
Plunk offers transparent and affordable pricing that scales with your needs.
The Free Plan costs nothing and includes 1,000 emails per month for each type - that's 1,000 automated emails, 1,000 transactional emails, and 1,000 campaign emails. You get unlimited contacts and can send from your own domain right from the start.
For businesses that need more volume, the Pay-As-You-Go Plan charges just $0.001 per email (that's $1 per 1,000 emails). This plan includes unlimited emails of all types, unlimited contacts, removes Plunk branding from your emails, adds email tracking and analytics, and still lets you send from your custom domain.
This pricing is significantly cheaper than competitors like Mailchimp or SendGrid, which can cost 3-5 times more for the same number of emails.
