Resend, sendgrid and pals roll out free email tiers: because your side project's 'millions of users' will totally fit under 100 sends a month

Developers of side projects require a dependable method to send authentication emails, password resets, and notifications. Several transactional email APIs offer great free tiers, providing a solid developer experience. Resend, Postmark, Mailjet, MailerSend, SendGrid, and Mailgun are notable options. These services enable developers to integrate email functionality into their applications, facilitating communication with users. The free plans offered by these companies allow developers to send a significant number of emails without incurring costs, making them ideal for small projects or testing purposes. For instance, some of these services provide up to several hundred emails per day for free, while others offer a limited number of emails per month. By leveraging these APIs, developers can focus on building their applications, rather than managing email infrastructure. The availability of these free tiers has significant implications for the development community, as it reduces barriers to entry and enables more projects to reach production.
