Where a Managed Service Helps a Postmark User
Postmark gives you a clean activity feed. Reading it, and acting on what it shows, still takes someone’s time.
Approval and Domain Checks Are Done with You
Postmark holds new accounts for review, and until approval you can send only to addresses on domains you verified. We prepare the domain and the use case so the review is not a surprise.
History That Outlasts 45 Days
Postmark keeps activity for 45 days by default. When a customer asks about an invoice from three months ago, that window is gone. Our logs are searchable and part of the service.
Someone Reads the Dashboard Daily
Bounces rise slowly, then fast. We watch delivery rates each day and trace a climb back to the form or import behind it.
Candor When Postmark Fits Better
If your developer wants a clean API and your budget is tight, Postmark may be the better purchase. A $15 plan with 10,000 emails is hard to argue with for a small app.
Who This Comparison Is Written For
Apps Whose Volume Crossed 10,000
The Basic plan includes 10,000 emails, and overage at $1.80 per 1,000 adds up quickly past that. Another plan tier changes the rate but not the work of managing the account.
Stores with Several Sending Domains
Postmark limits custom domains by plan, with 5 on Basic and 10 on Pro. If you send for a few brands, the account structure becomes a chore of its own.
Owners who want the whole job off their desk
A sender gives you speed and clean logs. It does not rewrite your plugin settings or answer when a receipt goes missing at 9 a.m. on Monday.
Choose Postmark if
- A developer wants a clean API and a published price
- Your volume stays under 10,000 emails a month
- You need a dedicated IP at 300,000 emails or more
Choose Cascadia if
- Nobody has time to read a delivery dashboard
- You need history and a person for single messages
- You want setup, templates, and monitoring in one price
Moving Off Postmark Step by Step
- 1
Inventory What Sends Mail
We list every system that mails customers: your store, your forms, your CRM, and any app with a Postmark server token. Nothing gets missed because it was set up years ago.
- 2
Authenticate a Domain of Its Own
We publish the records and warm the domain, so your main domain’s reputation stays separate. Your old Postmark domain keeps running meanwhile.
- 3
Cut Over and Test
Each stream moves in turn: receipts first, then resets, then notices. A person reads each message in a real inbox before the old token is retired.
- 4
Watch the First Month
Delivery rates are read daily while the new domain settles. You get a short report at the end of the month, and a question about any one message gets an answer.

Postmark Alternative Questions
What Postmark charges, where its limits sit, and what changes if you move.
See Managed Transactional EmailStill have a question?
How much does Postmark cost for a small site?
Basic is listed at $15 a month for 10,000 emails, with overage at $1.80 per 1,000 (October 2026). Pro starts at $16.50 and Platform at $18 for the same starting volume. Cascadia is $1 per 1,000 emails sent with a $5 minimum a month per domain, and our price includes the work around the sending.
Is there a free Postmark plan?
Yes. It gives 100 emails a month, does not expire, and allows no overage (October 2026). That suits testing and very light apps. A store with even a handful of orders a day will outgrow it within the first week.
Why does Postmark review new accounts?
Postmark approves accounts by hand to protect its sending reputation. Until approval, you can send only to addresses on domains you added and verified, and link tracking is off (October 2026). Review usually completes within 24 hours on weekdays.
How long does Postmark keep my message history?
Forty five days by default on every plan. Pro and Platform can extend it up to 365 days, and a custom retention add-on starts at $5 a month (October 2026). Our delivery logs are searchable and included, so there is no add-on to price.
What does a Postmark dedicated IP cost?
The listed price starts at $50 a month per IP, and it requires sending 300,000 or more emails a month on a Pro or higher plan (October 2026). Most small stores sit far below that, so a domain of its own on shared infrastructure fits better.
How many domains can I use on Postmark?
Basic allows 5 custom domains, Pro 10, and Platform is unlimited (October 2026). If you run several brands, check that count before choosing a plan. We price per domain, so each brand gets its own authenticated sending identity.
Are Postmark overage rates a risk?
They are published, which is a plus. Overage runs $1.80, $1.30, or $1.20 per 1,000 depending on plan (October 2026). Ours has no overage rate: every email is $1 per 1,000. The bigger risk is a bounce spike inflating volume, which is why we watch rates daily.
Can you replace Postmark in my WooCommerce store?
Yes. We swap the connection your plugin uses, send each template to a real inbox, and check order confirmations, resets, and shipping notices before the old token is retired. Nothing in your theme or checkout has to change.
What do I lose by leaving Postmark?
You lose a published, developer friendly API with a clean activity feed. What you gain is a person who reads the numbers, maintains the records, and answers for one customer’s missing email.
Will my Postmark suppression list come with me?
Yes. We import the addresses that bounced or complained, so the first day on the new domain does not mail known bad contacts. That import is part of the migration, which carries no setup fee.
Does Cascadia support marketing newsletters like Postmark streams?
No. Our service covers mail your site sends on its own: receipts, resets, notices, and alerts. A newsletter belongs in a marketing tool with its own unsubscribe handling, and we will say so rather than force it through.
Will switching cause downtime?
No. The new domain is built and warmed while Postmark keeps sending. Each category of mail moves over only after we have read test messages in real inboxes, and the old server token stays live until you say it is steady.
Who owns the sending domain and records?
You do. The DNS records sit on your domain, and the service has no sender account in your name to dispute later. If you leave, we hand over the records and templates, and tell you what to point your site at.
How do I cancel?
You can stop whenever you like. Service continues to the last business day of the month, with no partial refunds and no contract. Records, templates, and suppression data go with you, and we point you to where your site should send mail next.
