CloudMailin alternative that returns extracted fields
The right CloudMailin alternative depends on what you do with each email. If you store or route whole messages, CloudMailin is cheap and hard to beat, and the closest alternatives are other inbound pipes such as Postmark, Mailgun or SendGrid. If your code then digs order numbers, tracking numbers or invoice totals out of the body and the PDF, a parser like ParsedMail replaces that code and posts typed fields with a confidence score each.

What CloudMailin does well
CloudMailin is an inbound email to HTTP service with a long track record. You give it a target URL, it gives you an address (or receives on your own domain), and every message is posted to your app. You choose the format: Multipart Normalized, which CloudMailin recommends, JSON Normalized with the same structure as JSON, or Raw, the original message in one parameter. The normalized formats split each email into four parts: envelope, headers, body and attachments. On paid plans attachments can go straight to your own S3, Azure or Google Cloud Storage bucket instead of riding inside the POST.
It also has a clever delivery model. CloudMailin passes your HTTP status back to the sending mail server in real time. That makes it a good fit for apps that want to accept or reject mail as it arrives, for example rejecting messages to unknown ticket addresses.
CloudMailin pricing in 2026
From the CloudMailin plans page, checked in October 2026:
| Plan | Price a month | Messages a month | Max message size |
|---|---|---|---|
| Free | $0 | 10,000 | 512 KB |
| Starter | $25 | 10,000 | 2 MB |
| Professional | $45 | 20,000 | 10 MB |
| Premium | $85 | 40,000 | 50 MB |
| Corporate | $200 to $1,799 | 100,000 to 7 million | 50 MB |
Two numbers matter more than the price. The 512 KB cap on the free plan and the 2 MB cap on Starter rule out most emails with a PDF invoice or a scanned packing list, so teams that receive documents usually land on Professional or Premium. And the price only covers delivery. Extraction is still yours.
Why teams look for a CloudMailin alternative
- The parser behind it keeps breaking. CloudMailin hands you the body as plain text and HTML. Pulling a PO number, a ship date and five line items out of that, for dozens of sender layouts, is the part that eats engineering hours.
- The data is in the attachment. CloudMailin delivers or stores the PDF. Reading it means adding a PDF library, OCR for scans, and table logic on top.
- Delivery depends on your uptime. CloudMailin does not retry the HTTP POST itself. A 5xx from your app tells the sending server to try later (SMTP 450), and a 4xx bounces the email back to the sender. If your endpoint is down during a deploy, you rely on the sender's mail server to come back, and a bad 404 sends a customer a bounce. Teams running this setup usually add uptime monitoring for the webhook endpoint so a down handler is caught before senders start getting bounces.
CloudMailin vs ParsedMail
| CloudMailin | ParsedMail | |
|---|---|---|
| What your app receives | The email: envelope, headers, body, attachments | Your fields as typed JSON, with sender and subject |
| Field extraction | No, plus reply parsing for conversations | Yes, any field you describe in plain English |
| PDF and scan reading | No, stores or forwards the file | Yes, PDF, CSV and text; scans and images on paid plans |
| Confidence per field | Not applicable | Yes, 0 to 1 on every value |
| When your endpoint fails | No POST retry; 5xx defers to the sender's server, 4xx bounces | The email is already accepted; 5 signed retries over about 15 hours, then replay from the log |
| Message size | 512 KB free, 2 MB to 50 MB on paid plans | 25 MB per email on every plan, first 8 attachments read |
| Entry price | Free for 10,000 messages, Starter $25 | Starter $49 a month, or $24 billed yearly, 1,000 emails |
The honest read: CloudMailin wins on cost per message by a wide margin, and ParsedMail wins when the work you pay a developer for is turning the message into data.
Which CloudMailin alternative fits your case
You need the raw message at volume. Stay on CloudMailin, or compare it with the inbound features of the sending service you already pay for. We wrote up the differences with Postmark Inbound and SendGrid Inbound Parse, which both post the message and leave extraction to you.
You need fields from the email. Order confirmations, carrier updates, lead notifications and supplier invoices, where the next step is a row in an ERP, CRM or spreadsheet. That is what ParsedMail does. Describe the fields, forward the mail, and the inbound email webhook receives finished JSON. Our parse email to JSON page shows the full request and response.
You need fields but no code at all. Mailparser and Parseur are template or AI parsers with no-code exports. The trade-offs are in our best email parser roundup.
What it costs at real volumes
A carrier sends 1,200 shipment updates a month, each a short email with a tracking number, a status and an ETA, and about 150 of them carry a one page PDF proof of delivery.
- CloudMailin. Starter at $25 a month covers the messages if every PDF stays under 2 MB. Your code then extracts tracking number, status and ETA from 1,200 bodies and reads 150 PDFs. Build time is days, and maintenance is ongoing whenever the carrier changes its template.
- ParsedMail. 1,200 emails and 150 attachment pages need Growth, $74 a month billed yearly for 5,000 emails and 2,000 pages, which also adds the review queue for low confidence values. No extraction code. If you trim the flow to 1,000 emails, Starter at $24 a month covers it.
The difference is $49 a month against the hours your team spends on parsing. If that is less than one hour of developer time a month, CloudMailin plus your own code is the cheaper route. If the parser is a regular ticket, it is not. Full plan details are on pricing.
Switching one flow in a week
- Day 1. Create an inbox, describe the fields with the same names your current code outputs, and forward 20 real emails, including the messy ones.
- Days 2 to 6. Add a forward or BCC so both services receive live mail. Check confidence scores and sharpen any field description that comes back under 0.8.
- Day 7. Point the sender or the forward at the ParsedMail address, switch your handler to the signed ParsedMail webhook, and remove that flow from CloudMailin.
