★★★★★Trustpilot · October 2026
Postcards to several recipients never arrived; PostGrid cited USPS handoff records and declined a refund.
We used PostGrid for 30 days to send the same postcard and letter to 10 test addresses, the same job we give every direct mail tool we review. It scored 2.5 out of 5 overall and placed fourth of the six tools we tested.
Set-up took us 155 minutes. Of the 20 pieces we sent, 13 were delivered correctly, and delivery took 11 days. Support replies took a median of 890 minutes, and 2 of our 3 replies were useful. PostGrid added nothing to our online store's pages, and checkout was unchanged.
PostGrid suits developers and operations teams that want published per-piece prices, cheque mailing and a free plan to start on. If you want a no-code campaign builder, or you need every piece to arrive, look at the tools that scored higher.
How we scored it

The best direct mail automation
Before you pick PostGrid, see how all 6 tools ranked in the same test.
PostGrid in plain terms
PostGrid prints and mails letters, postcards and cheques for you. You build a template or upload a PDF, add a recipient, and send it through PostGrid's API, its dashboard or an integration such as HubSpot or Zapier. A print partner then prints the piece and hands it over for delivery.
It also sells a separate address verification API that covers the US, Canada and more than 245 countries, and it has regional sites for Canada, the UK and Australia. Its team is 65 people.
Compared with no-code tools that many marketing automation teams use, PostGrid is API-first. Its Starter plan is free, with no monthly fee: you pay only for each piece you mail, at prices it publishes.
What happens after you sign up
Sending mail with PostGrid takes four steps, and most of the work is in the first one.
1. Create. Build a template or upload a PDF, then add a recipient.
2. Send. Submit the piece through the API, the dashboard or an integration such as HubSpot or Zapier.
3. Print. A print partner prints the piece and hands it to delivery, typically within two business days.
4. Track. Starter includes standard mail tracking. Enterprise adds more detailed tracking.
What you get
PostGrid's features cover sending mail and cheques from your own systems. The more advanced options, like HIPAA mail and custom envelopes, are Enterprise only.
Print and mail API
Send letters, postcards and cheques from your own code or dashboard, on every plan.
Cheque mailing
Print and mail cheques with a MICR line, which suits finance teams paying suppliers or refunds.
Address verification API
Check addresses in the US, Canada and over 245 countries, priced separately.
Certified and express mail
Add certified mail with a return receipt or express delivery to a piece for an extra charge.
Many integrations
Connect to tools such as Salesforce, HubSpot, Zapier, QuickBooks, Klaviyo, Stripe and NetSuite.
Who gets the most out of PostGrid
PostGrid is a good match for teams with a developer who want to send mail and cheques at clear per-piece prices. It's a weaker fit for marketers who want drip campaigns built without code.
A good fit for
- Developers who want a documented REST API
- Teams mailing in the US, Canada, UK or Australia
- Finance teams sending cheques
- Healthcare teams that need HIPAA mailing and a BAA
Not a good fit for
- Buyers who want a no-code campaign builder with drips
- Volume senders who want public enterprise prices
- Senders to Europe who want premium print quality
- Buyers who expect refunds on mail handed to USPS
PostGrid vs Lob, Handwrytten and doing it by hand
Lob is the closest rival: another API-first mail service with a free plan. It scored 3 out of 5 and came second, ahead of PostGrid on ease of use, fees and store impact. Lob's paid plans start at $260 a month for lower per-piece rates. Handwrytten came first with 3.5, for handwritten cards from $100 a month. See our best direct mail list for the full ranking.
Doing it by hand or through a print shop works for the odd mailing. PostGrid automates printing, postage and tracking, with each piece priced up front, from $0.902 for a postcard on Starter.
| Option | Price | How it compares |
|---|---|---|
| PostGrid | Free | Starter has no monthly fee; you pay per piece, from $0.902 for a postcard. |
| Lob | Free | Free Developer plan paid per piece; paid plans from $260 a month lower the rates. |
| Handwrytten | $100 a month | Robots write real-pen cards and notes and mail them for you. |
| By hand or print shop | Quote per job | You print, stamp and post yourself, or hand designs to a local printer. |
Our 30-day PostGrid test
We tested PostGrid from September 30 to October 29, 2026, 30 days in all. We sent the same postcard and the same letter to 10 test addresses, 20 pieces in total, and checked what arrived and how long it took. We connected it alongside our made-up online store to see if it touched the shop. The full method is in how we test.
Getting set up took 155 minutes. That's a long afternoon for one postcard and one letter, and you'll get there faster with someone who's comfortable working with an API.
Of our 20 pieces, 13 were delivered correctly and 7 were not. So roughly a third of what we sent had a problem, which is a lot if each piece is a cheque or an important notice. Delivery took 11 days.
We contacted support three times. The median wait was 890 minutes, so expect most of a working day, and 2 of the 3 replies solved our question. PostGrid added no script to our storefront, so pages and checkout were unchanged.
| What we measured | Result | What it means |
|---|---|---|
| Set-up time | 155 min setup | Over two and a half hours to get going, so set aside real time or get developer help. |
| Mail pieces delivered correctly, out of 20 | 13/20 mail pieces delivered correctly | About a third of pieces had a problem, so check your first batch closely. |
| Effect on our online store's pages and checkout | No storefront script; checkout unchanged | PostGrid won't slow your shop or change how customers pay. |
| Support reply time and useful replies | 890 min median; 2/3 useful replies | Expect to wait most of a working day for help, and not every answer will fix the issue. |
PostGrid did the basic job without touching our store, and its free plan and published prices make it easy to try. But set-up was slow, 7 of 20 pieces went wrong, delivery took 11 days and support was slow to reply. An even 2.5 across the board put it fourth of six.
Tested September 30, 2026 to October 29, 2026.
The good and the bad from our test
Free plan with clear prices
Starter is free and covers up to 500 mailings and 50 cheques a month. Every piece has a published price, from $0.902 for a 4x6 postcard sent First Class.
No effect on your store
PostGrid added no script to our storefront, and checkout was unchanged. It works in the background.
Cheques and wide reach
It mails cheques with a MICR line for $1.18 each on Starter, and has regional sites for Canada, the UK and Australia.
Seven of 20 pieces went wrong
Only 13 of our 20 mail pieces were delivered correctly. For cheques or customer letters, that's a gap you'd need to watch.
Slow set-up and slow delivery
Set-up took 155 minutes and our pieces took 11 days to arrive. Plan well ahead for anything time-sensitive.
Unclear refund terms
We couldn't find PostGrid's refund terms, and one Trustpilot user said it refused a refund for undelivered postcards, pointing to USPS handoff records.
Pros
- Free Starter plan with no monthly fee
- Published per-piece prices
- Cheque mailing with a MICR line
- No effect on store pages or checkout

Cons
- Only 13 of 20 pieces delivered correctly
- 155 minutes to set up
- Our pieces took 11 days to arrive
- Volume pricing only by Enterprise quote
- No published refund or cancellation terms

Is PostGrid safe for your customer data?
PostGrid says it has a SOC 2 Type II report for its Print & Mail and Address Verification products, audited by Prescient Assurance and shared under NDA. It also says it completed a HIPAA framework audited by Compliancy Group and signs a BAA, offers PCI DSS 3.2.1 on request, lists GDPR and PIPEDA, and is hosted on Amazon Web Services.
One HIPAA page describes the product as SOC 2 Type 2-ready rather than certified, so confirm the status before relying on it. PostGrid doesn't say how long it keeps your data or whether it's used for AI training.
Ask for the SOC 2 report under NDA and sign a BAA before sending any health information.
What PostGrid users say
There's very little user feedback. On Trustpilot, checked November 3, 2026, PostGrid has 3.0 out of 5 from just 4 reviews, 3 of them in the last 12 months. Three in four give 1 star, and the profile is unclaimed. Snippets from G2 and Capterra show very high ratings.
Happy users mention easy sign-up, a good design editor, a good API and helpful service. The complaints are about postcards that never arrived with a refund refused, poor quality and high prices for sends to Europe, and missing tracking and return addresses on UK letters.
What users praise
- Easy sign-up and design editor
- Good API and customer service per one reviewer
- High G2 and Capterra ratings
What users complain about
- Postcards reported as never arriving with refund refused
- Poor quality and high price for European sends
- Missing tracking and return addresses on UK letters
Recent user reviews, in short
Summarised in our own words, not quoted. Reviewer names are left out.
★★★★★Trustpilot · April 2026
Found sign-up and the editor easy; noted the contacts section lacks labels.
★★★★★Trustpilot · March 2026
Liked the API and support but said postcards sent to Europe were poor quality and overpriced.
★★★★★Trustpilot · August 2024
Reported missing tracking and return addresses on UK letters and slow support; moved to another provider.
Our test sits between the two camps. Set-up worked and our store was untouched, but 7 of our 20 pieces went wrong, which fits the complaints about mail that doesn't arrive.
Ratings checked November 3, 2026.
PostGrid alternatives worth a look
Three tools ranked above PostGrid in our test, and two ranked below. Here's how they compared.
Handwrytten
Handwrytten came first with 3.5 out of 5, ahead of PostGrid on every part. It suits personal handwritten cards like thank-you and follow-up notes.
Lob
Lob scored 3 out of 5 and ranked second, beating PostGrid on ease of use, fees and store impact. It suits developers and larger teams sending mail at volume.
Postal
Postal scored 3 out of 5, with better ease of use, store impact and support than PostGrid. It suits teams wanting managed swag and gifting, sold by quote.
Postalytics
Postalytics scored 2.5 out of 5, harder to use than PostGrid but with better support. It suits marketers adding mail to digital campaigns, from $199 a month.
Sendoso
Sendoso came last with 2 out of 5. It suits B2B sales teams running gifting and mail programs, with prices by quote.
2.5/5
Should you use PostGrid?
PostGrid is a reasonable, low-risk way to start sending mail and cheques from your own systems. Its free plan and published per-piece prices are its strengths, and it didn't touch our store. But 7 of our 20 pieces went wrong, set-up took 155 minutes and delivery took 11 days, which is why it scored 2.5 out of 5 and placed fourth of six.
If you have a developer and want clear prices, try the free Starter plan with a small batch to your own addresses first. If you need better delivery results, Lob or Handwrytten did better in our test.
PostGrid suits developers who want free, clearly priced mail and cheque sending; anyone needing reliable delivery or a no-code builder should look elsewhere.

Frequently asked questions
How much does PostGrid cost?
PostGrid's Starter plan is free, with no monthly fee. You pay per piece: $0.902 for a 4x6 First Class postcard, $1.059 for a black-and-white First Class letter and $1.18 for a cheque. Enterprise is a custom quote with volume pricing. We checked these prices on November 3, 2026.
How did you test PostGrid?
Over 30 days, from September 30 to October 29, 2026, we sent the same postcard and letter to 10 test addresses. We timed set-up, counted how many of the 20 pieces were delivered correctly, checked our test store's pages and checkout, and measured support reply times and how useful the answers were.
Does PostGrid have a free plan?
Yes. Starter is free and covers up to 500 mailings and 50 cheques a month, with 1 user, 10 templates, the standard print network and tracking. You still pay for each piece you send. Above 500 mailings a month, you need to contact support for a price.
Is PostGrid HIPAA compliant?
PostGrid says it completed the HIPAA framework, audited by Compliancy Group, and signs a BAA. HIPAA mailings are an Enterprise feature, though, so you can't send health information on the free Starter plan. Ask for the paperwork and sign a BAA before you start.
Can PostGrid mail cheques?
Yes. PostGrid prints and mails 8.5x11 cheques with a MICR line, so banks can read them. On the free Starter plan, each cheque costs $1.18, and you can send up to 50 a month. That makes it a practical option for finance teams paying suppliers or sending refunds.
How fast is PostGrid delivery?
PostGrid says orders are handed to delivery within two business days. First Class letters then take 5-7 business days, and Standard Class, which is for marketing only, takes 10-15 business days. In our test, our pieces took 11 days to arrive.
