Have questions?

Do you offer a free trial?

All new accounts start off on our free developer plan with 100 emails per month. Use it for however long you need, it doesn’t expire.

What happens if I go over my monthly email limit?

Extra emails on our paid tiers are calculated at the end of your billing cycle and included with your cost for the upcoming month.

Do you have a tier smaller than 10,000 emails/month?

We do not offer a tier between 100 emails/month (our free developer plan) and 10,000 emails/month.

Do you offer annual plans?

Not right now, but we’d like to! We’re looking at introducing annual plans, which can offer some flexibility to customers who have lower and/or seasonal volume. Contact us if you’d like to be notified when we introduce annual plans.

Do you offer dedicated IPs?

Yes: dedicated IPs are available to high-volume senders. Read about our policy for issuing dedicated IPs.

What payment types do you accept?

We accept payments via Visa, MasterCard, American Express, Diners, and JCB. We do not accept PayPal or Purchase Orders.

Do you offer high-volume plans?

Yes! Contact us to learn about our high-volume pricing.

Do unused emails roll over into the next month?

No. If you are under your email limit at the end of a billing period, the unused emails do not roll over to the next billing period.

Do you offer a discount for bootstrapped companies?

Yes! If you’ve launched your product, are charging for it, and haven’t taken outside investment, contact our support team and we’ll give you $75 account credit to help with your email costs.

Here’s what our customers think of us

Postmark has a reputation for high quality. Even though there are several good companies, we were convinced by Postmark’s clear documentation and transparent roadmap. Further, building email infrastructure is really a partnership — we wanted to invest in a platform that would continue to grow along with our needs, not one that was fairly static and falling behind the technology curve.

I was shocked to see Postmark open rates were an 11% improvement over SES in our test. Needless to say we started sending all of our transactional email through Postmark.

We’re really happy we decided to use Postmark for ITV’s British Soap Awards. We only count votes from verified email addresses and Postmark’s excellent delivery has lead to our highest verification percentage ever. We'll definitely use Postmark again!
