Join thousands of happy companies using Postmark

Postmark is a blackbox which works. It’s apparent that the guys at Wildbit really care enough to scratch an itch the entire SaaS world needs help with, and they’ve nailed it.

What happens when credits run out?

To avoid lost emails or delayed sending, Postmark will automatically send alert emails when your credits are close to running out. Or better yet, set your credits to auto-renew and never worry about interruption.

What payment types do you accept?

We accept payments via Visa, MasterCard and American Express. All purchases can be made instantly in your account and credits are applied right away. We do not accept PayPal or Purchase Orders.

Do you offer a free trial?

Absolutely. We offer 25,000 free credits, allowing you to send 25,000 emails before you purchase. If you like what you see, just purchase more.

Do credits ever expire?

Nope. No matter how many credits you purchase, they never expire. Use them whenever you want.

Why is Postmark for transactional email only?

By focusing on transactional email only, ISPs can build a reputation on consistent, high engagement messages. This allows us to have extremely fast delivery to the inbox without tarnishing our reputation from large bulk email campaigns that sit in the queue.

Wildbit supports bootstrapped companies


The best companies use the best services to power their businesses. Bootstrapped companies can’t always afford the best from the start, so we’re offering 50,000 free credits for companies that are charging for their products and have not taken any outside funding. Contact to find out how.
