CloudMailin Alternative: Inbound Email Parsing That Returns Fields, Not Just a Webhook Payload
Get the field you actually wanted, not a JSON copy of the whole email
CloudMailin is a solid inbound email API: point an address at it and every message arrives at your webhook as clean JSON. What it hands you is the email, not the data inside it. MailParse is a CloudMailin alternative for the other half of that job: name the fields you want, such as invoice_total or tracking_number, and get Excel, CSV, or JSON back with no extraction code to write. Connect Gmail, Outlook, Microsoft 365, or IMAP, or POST to the REST API.

MailParse is a CloudMailin alternative for teams that want named business fields out of inbound email instead of a raw webhook payload. CloudMailin is an inbound email API: it receives the message, separates the MIME parts and attachments, normalizes the text, and POSTs the whole email to your endpoint as JSON, so your engineers still write the code that finds the invoice number or the order total. MailParse asks you to name the fields you want and returns them as Excel, CSV, or JSON, with no parsing code to maintain. If your goal is piping raw inbound mail into your own application at volume, CloudMailin is the better and cheaper tool, and its free tier covers 10,000 emails a month.

CloudMailin does one job and does it well. You point an email address or an MX record at their servers, and every message that arrives is turned into an HTTP POST to your application. Their servers handle the parts of email that are genuinely unpleasant to write yourself: reading the MIME structure, splitting the plain text part from the HTML part, pulling attachments out and handing them to you or dropping them in your own S3 or Google Cloud bucket, and normalizing a mess of character sets into UTF-8. The payload arrives as JSON, multipart, or raw, and it contains the headers, the envelope, the SPF result, the body in both formats, and the attachment metadata. For a developer building reply-by-email, support ticket ingestion, or an application inbox, that is exactly the right shape of tool.
The gap shows up one layer later. CloudMailin gives you the email. It does not give you the number in the email. If 400 supplier confirmations land each month and you need the purchase order number, the ship date, and the line items, CloudMailin delivers 400 clean JSON documents and somebody on your team still writes and maintains the code that finds those values in each vendor layout. That code is where the real cost lives, because every supplier formats their email differently and each one changes it eventually. MailParse starts at that point: you name the fields once, and it reads them across varied layouts, including line items sitting in an HTML table, then returns a spreadsheet or structured JSON. This page compares the two honestly, including the cases where CloudMailin is clearly the tool you should buy.
What changes when you swap the webhook for named fields
The differences that matter once the email is already arriving reliably.
Name the field instead of writing the parser
CloudMailin hands your endpoint the full message and leaves extraction to you. In MailParse you type the field names you want, such as invoice_number, po_number, or tracking_number, and those become columns. The regular expressions and per-vendor branches never get written, so they never break.
Reads varied layouts from one setup
Custom parsing code is usually written against the first sender you tested. MailParse keys off the field you named rather than a fixed position in the markup, so a second vendor with a different template parses without a second code path.
Turns HTML tables into rows
Order and invoice email often carries the detail in an HTML table whose row count changes every message. MailParse turns each row of that table into its own spreadsheet row, which is the case that hand-written parsers handle worst.
Spreadsheet output, not only JSON
CloudMailin speaks JSON to your servers, which is right for an application and wrong for a finance team. MailParse writes a formatted Excel workbook or CSV a person can open and check, and still offers JSON through the REST API and webhooks when code is the consumer.
No MX record or DNS change
An inbound email API needs you to route mail to it. MailParse connects to the Gmail, Outlook, Microsoft 365, or IMAP mailbox the email already arrives in, so nothing about your mail routing changes and you can run a backlog of older messages in the same pass.
Non-developers can change it
When the field you need changes, editing a saved template takes a minute and does not require a developer, a pull request, or a deploy. On a custom pipeline built over an inbound webhook, the same change is an engineering ticket.
How to move an extraction job off CloudMailin
Four steps, and you can keep CloudMailin for the traffic that genuinely belongs there.
List the fields your code pulls today
Open the parsing code sitting behind your CloudMailin webhook and write down the values it extracts, such as order number, total, ship date, or lead email. That list is your MailParse setup.
Connect the mailbox instead of the MX record
Link the Gmail, Outlook, Microsoft 365, or IMAP inbox those messages already land in, or POST raw email to the MailParse API if you would rather keep the traffic flowing through your own service.
Name the fields and check a real batch
Enter the field names and run a batch of your actual messages, ideally from two or three different senders. Because extraction keys off named fields, varied layouts should come back correct without separate rules.
Send the output where it needs to go
Download Excel or CSV for review and import, or point the JSON output at your CRM, database, or a Zapier or Make step. If some traffic still needs raw inbound delivery, leave that side on CloudMailin.
Who looks for a CloudMailin alternative
Almost always teams whose problem moved from receiving email to reading it.
Teams maintaining parsing code
The webhook works fine, but the extraction layer behind it has grown a branch per vendor and breaks quietly when a sender restyles a template. Naming fields replaces that code with a template anyone on the team can edit.
Finance and operations
Accounts payable and fulfillment want a spreadsheet to review and import, not JSON at an endpoint. Pull totals, dates, invoice numbers, and line items into Excel or CSV without asking engineering for a report.
Small teams with no spare engineer
A developer-first inbound API assumes a developer is available to build on top of it. If the parsing work would sit in a backlog for a quarter, a tool that needs no code ships the same week.
One-off and backlog jobs
Routing an MX record is heavy for a job that runs once. Connecting an existing mailbox and parsing two years of archived order confirmations into one spreadsheet takes a single pass.
MailParse vs CloudMailin, honestly
They solve adjacent problems
CloudMailin is an inbound email API and MailParse is a field extractor. CloudMailin gets the message to your code cleanly. MailParse gets the values out of the message. Plenty of teams have a real use for both, and swapping one for the other only makes sense when your actual bottleneck is extraction.
CloudMailin wins on raw volume and price
CloudMailin lists a free tier covering 10,000 emails a month and paid plans from $25 a month for 10,000 messages, checked August 2026. If your requirement is high-volume inbound delivery into your own application, that is far cheaper per message than any extraction tool and you should use it.
MailParse wins when the value is in the field
Paying per parsed email only makes sense when each email yields data somebody would otherwise retype. For 200 invoice emails a month that is a straightforward trade against hours of manual entry or a maintained parser. For 200,000 raw messages a month it is not the right unit of pricing, and we would tell you so.
Message size and routing differ
CloudMailin publishes a per-message size ceiling that rises with the plan, from 512KB on the free tier to 50MB on higher plans, and expects mail routed to its servers. MailParse connects to a mailbox you already own, so there is no DNS or MX change, and files up to 50MB are supported on Plus and Pro plans.
Neither reads the inside of a PDF attachment
This one catches people out. MailParse reads the email itself, the body text and any HTML tables in it. If the number you need is printed inside an attached PDF or Word file, that is document parsing, a separate product category priced per page, and neither an inbound email API nor MailParse solves it.
Different buyer
CloudMailin is documentation-first and aimed at engineers who want control. MailParse is aimed at the operations, finance, or RevOps person who owns the outcome and does not want to open a ticket every time a field changes. Pick based on who will maintain it in six months.
Inbound email parsing options compared
CloudMailin and SendGrid Inbound Parse both receive email and hand it to your code. MailParse extracts named fields and writes a spreadsheet. Here is the honest side by side, with credit to each where it leads. For the wider field of tools, see the best email parser guide, and for the developer route the email parser API.
| What matters | CloudMailin | SendGrid Inbound Parse | MailParse |
|---|---|---|---|
| What you get back | The whole message as JSON, multipart, or raw, with headers, both body parts, and attachment metadata | The whole message posted to your URL, with headers, text, HTML, attachments, SPF and spam scores | Only the fields you named, as columns |
| Business-field extraction | No, your code finds the invoice number | No, your code finds the invoice number | Yes, you name the field and it is read across varied layouts |
| Spreadsheet output | No, JSON to an endpoint | No, form data to an endpoint | Excel and CSV, plus JSON via API |
| Setup | Route an address or MX record, then build the endpoint | Point an MX record at SendGrid and build the endpoint | Connect Gmail, Outlook, 365, or IMAP, or POST to the API |
| Who maintains it | A developer, in your codebase | A developer, in your codebase | Whoever owns the process, in a saved template |
| Line items in an HTML table | Delivered as HTML for you to split | Delivered as HTML for you to split | Each table row becomes its own spreadsheet row |
| Message size ceiling | 512KB free, up to 50MB on higher plans | 30MB total including attachments, per SendGrid docs | Files up to 50MB on Plus and Pro |
| Entry price | Free tier at 10,000 emails a month, paid from $25 a month | A feature of a SendGrid account rather than a separate line item | Free to try, paid plans start at $24 a month |
| Best for | High-volume raw inbound into your own application | Teams already sending through SendGrid | Turning email into named fields without writing a parser |

Frequently asked questions
What is the best CloudMailin alternative?
It depends on which half of the job you need. If you want raw inbound email delivered to your own application, the closest alternatives are SendGrid Inbound Parse, Mailgun routes, and Postmark inbound, which all POST the parsed message to a URL you control. If your real problem is pulling named values out of those messages, an extraction tool such as MailParse fits better, because it returns the fields rather than the email.
What does CloudMailin actually do?
CloudMailin is an inbound email API. You route an email address or MX record to their servers, and each arriving message is converted into an HTTP POST to your application in JSON, multipart, or raw format. The payload carries headers, envelope details, the plain text and HTML bodies, and attachments, which can also be stored in your own cloud bucket. It handles MIME and character sets so your code does not have to.
Does CloudMailin extract custom fields like invoice numbers?
No. CloudMailin parses the structure of the email, meaning headers, MIME parts, and attachments, and delivers the whole message cleanly. Finding a business value such as an invoice number, order total, or tracking number inside the body is left to code you write and maintain. That distinction is the main reason teams look for a field-level tool alongside or instead of it.
How much does CloudMailin cost?
Checked in August 2026, CloudMailin lists a free plan covering 10,000 emails a month at 512KB per message, Starter at $25 a month for 10,000 emails at 2MB, Professional at $45 for 20,000 at 10MB, and Premium at $85 for 40,000 at 50MB, with Corporate plans running from $200 to $1,799. Paid plans advertise a seven day trial. Confirm current figures on cloudmailin.com before budgeting.
Is CloudMailin or MailParse cheaper?
For raw inbound volume, CloudMailin is dramatically cheaper, and we will not pretend otherwise: 10,000 messages a month on its free tier is more than any extraction tool includes. The pricing units are different. MailParse charges per parsed email because each one produces structured fields, so it is worth comparing against the hours of manual entry or parser maintenance it replaces, not against a per-message delivery rate.
Do I need to change my MX record to use MailParse?
No. MailParse connects directly to a mailbox you already own through Gmail, Outlook, Microsoft 365, or IMAP, so your mail routing and DNS stay exactly as they are. That also means you can parse email that has already arrived, which an inbound API cannot do because it only sees messages routed to it after setup.
Can I use CloudMailin and MailParse together?
Yes, and for some teams that is the right answer. Keep CloudMailin for application traffic that must reach your own endpoint in real time, and use MailParse for the reporting and back-office extraction where somebody wants a spreadsheet of totals and dates. You can also POST raw email to the MailParse API from your existing pipeline if you prefer one entry point.
Does MailParse read data inside PDF attachments?
No, and it is worth being clear about it. MailParse reads the email itself, the body text and any HTML tables it contains. Pulling values out of an attached PDF or Word file is document parsing, a different product category usually priced per page. Inbound email APIs do not do it either, so if your data only exists inside attachments you need a document extraction tool.
What is an inbound parse webhook?
An inbound parse webhook is a service that receives email on your behalf and forwards it to a URL in your application as an HTTP POST. Instead of running a mail server and writing MIME handling code, you point an address or MX record at the provider and receive a structured payload with the sender, subject, body, and attachments already separated. CloudMailin and SendGrid Inbound Parse both work this way.
