    About Postmark

    Postmark is an email delivery service for developers. Your application sends transactional email through its API or SMTP, such as password resets and notifications.

    Message streams keep promotional mail like newsletters on separate infrastructure, which protects the delivery of your transactional messages. Postmark vets new senders and follows deliverability best practice, and does not require a dedicated IP address.

    Official libraries cover Node.js, Python, Ruby, PHP and .NET, and migration guides help if you are moving from another provider.

    Pricing: Postmark has a free plan of 100 emails a month for testing, and paid monthly plans that start with a bundle of 10,000 emails and charge for extra emails per thousand. Higher plans add longer data retention, more sending domains and inbound email processing. No credit card is needed to start.

    Why it suits tourism businesses

    Tourism businesses rarely use Postmark directly. It sits behind booking systems, websites and apps that need to send confirmations, receipts and account emails.

    If your developer or booking platform sends system emails, Postmark is one way to deliver them. A small operator without technical support will usually get this through the tools they already use.
