Pros and cons
Pros
- The published price for the higher contact tier is $15, under the $19 Mailjet asks for the same list size.
- A free plan is included, with 100 emails/month free on it for testing sends before paying.
- Support runs on email, chat and phone, wider than the single-channel pattern most of the category settles for.
- The brand is listed for the small business audience, and the site's small-business weighting of 94.5% backs that fit.
Cons
- The free plan covers 100 emails/month free, a smaller allowance than the Up to 2000 contacts, 6000 emails per month, 5 users on offer from Zoho.
- Only the entry price is published, at $15, while the category median at that size sits at €49.
- The listed model is a free plan, so the free trial route that 63.8% of the category offers is not among the options here.
- Support runs on email, chat and phone, which leaves out the community channel that 27.3% of the category carries.
Who it suits
- Small businesses that need dependable transactional sending on a modest contact list and a clear bill
- Teams that put reachable support on email, chat and phone ahead of a wide feature grid
- Anyone willing to start on the free plan and move up only once their sending volume grows
Who should look elsewhere
- Buyers who want the most generous free allowance, since Zoho offers more on Up to 2000 contacts, 6000 emails per month, 5 users than Postmark offers on 100 emails/month free
- Shoppers comparing many published tiers, since only $15 is stated here against a category high of €131.54
The company behind it
Postmark runs under the legal entity AC PM, LLC, with its headquarters in the United States. That is a US operation, and prices are quoted in USD. Support is the part that sets it apart within this group, since the team is reachable on email, chat and phone. A phone line is the least usual channel in the email marketing category, carried by only 38.2% of the brands, while a help centre sits at 85.5%. The service is aimed at the small business audience, which lines up with how the site weights small business at 94.5%. Entry comes with 100 emails/month free on the free plan, so a small team can test real sends before it commits to a paid tier. For buyers weighing choice against clarity, a short support list and a stated free allowance are easier to plan around than a wide feature grid.

Frequently asked questions
How much is Postmark for a large contact list?+
The stated price at that tier is $15, quoted in USD. That places Postmark at the 2 position on price at that size among 10 brands compared. The category median at the same size is €49, so the figure sits below the middle of the field.
Does Postmark have a free plan?+
Yes, and the free plan carries 100 emails/month free. That is enough for a small team to run transactional sends before any spend. 51.3% of the brands in the category offer a free plan, so this is an entry point rather than a differentiator on its own. Moving past it means paying $15 for the higher contact tier.
What support can I get from Postmark?+
Support runs on email, chat and phone, so an account can be reached by email, chat, phone or the help centre. A phone line is the rarer channel here, since only 38.2% of the category carries one, and a help centre is the most common at 85.5%. That mix suits teams that want a person rather than a queue.
Who is Postmark built for?+
It is listed for the small business audience, and the site weights small business at 94.5% in that field. The same site puts beginners at 47.8%, so this is a deliberate lean toward smaller companies rather than a general tool. It fits teams sending steady transactional email rather than running a large campaign programme.
Which company runs Postmark?+
The service is published by AC PM, LLC, with headquarters in the United States. That makes it a US operation, and every figure in its pricing is quoted in USD. Knowing the legal entity matters for anyone reading the terms of service before signing up to a paid tier.
Is Postmark cheaper than Mailjet for a large contact list?+
Yes. Postmark states $15 at that tier, while Mailjet lists $19 for the same contact count. Both figures are in USD, so the comparison holds without conversion. At the smaller tier the gap narrows, with the category median at €21.49.
How does the free plan compare with Zoho?+
Zoho is the more generous starting point, offering Up to 2000 contacts, 6000 emails per month, 5 users on its free tier. Postmark's 100 emails/month free is a working allowance for transactional sends, though a smaller one. Teams that need several users and a wider contact list from the start may find more room at Zoho.
