TL;DR
Forward one receipt email at a time to receipts@my.monarch.com from the Monarch account email, a household-member email, or another sender you have verified in Monarch.
Monarch accepts body-only messages and currently documents JPG, PNG, WEBP, HEIC, HEIF, and PDF, with 10 MB per attachment and 30 MB per email; Expensent's attachment support is narrower.
A successful import is not the same as a match. Monarch matches only posted transactions and remains responsible for parsing, matching, Autosplit, categories, and notifications.

1. Send receipts to Monarch's current address
Monarch currently documents receipts@my.monarch.com as its receipt-import address. Forward one receipt per email from an address Monarch recognizes; Monarch can use a supported attachment or receipt information in the email body.
After delivery, the receipt appears in Monarch and may be matched to a posted transaction. A missing receipt is an intake problem, while an imported but unattached receipt is a matching problem.
Copy the address from the current Monarch documentation
Receipt destinations can change. Confirm the address in Monarch's live Help Center before saving a contact, rule, or team procedure.
2. Verify the mailbox that will send
The Monarch account email and household-member emails are documented as already verified. For another address, open Transactions > Receipts > Settings > Add new email, then enter the six-digit code Monarch sends to that inbox.
This sender check is separate from Gmail's forwarding-destination verification. A mailbox connected to Expensent must still be accepted by Monarch, even though the Expensent route does not configure Gmail forwarding.
3. Prove the route with one receipt
Forward one recent, readable receipt from the accepted mailbox and leave its useful subject, body, and attachment intact. Avoid a bundled message containing several purchases.
Confirm that the receipt appears in Transactions > Receipts before adding recurring automation. Monarch notifications help distinguish an import result from a matching result.
4. Use formats supported by the whole route
Monarch currently lists JPG, PNG, WEBP, HEIC, HEIF, and PDF, with a 10 MB limit per attachment and 30 MB per email. Expensent's current attachment route supports PDF, JPG, and PNG, so use the narrower shared set when routing through Expensent.
Monarch can also turn a body-only receipt email into a receipt image. Expensent's body-as-proof preference makes those candidates visible and affects newly created rules; it does not rewrite existing rules.
5. Know what happens after import
Monarch matches imported receipts using amount, date, and merchant information, and only posted transactions are eligible. A receipt can arrive correctly while its card charge is still pending.
If the expected transaction has posted and the receipt remains unmatched, open the receipt and use Find match. Treat sent, imported, and matched as separate states.
6. Automate recurring receipt emails
Manual forwarding works well for occasional receipts. Gmail's native automatic-forwarding setup is blocked when Google asks Monarch's shared destination to open a verification link.
Expensent uses OAuth-connected Gmail or Outlook access to find receipt emails and send them from the connected mailbox. This route supports historical catch-up and recurring rules built from a proven sender and subject pattern.
The mailbox still must be accepted by Monarch, and Monarch remains responsible for import and matching after each message arrives.
7. Troubleshoot the right stage
If the receipt is absent from Transactions > Receipts, check the destination, sender verification, notification, and file limits. If it appears but is not attached, check posted status and the receipts amount, date, and merchant evidence.
Keeping intake and matching separate avoids duplicate sends and gets the reader to the relevant troubleshooting guide faster.
The clean diagnostic boundary
Not in the Receipts tab means intake troubleshooting. In the Receipts tab but unattached means matching troubleshooting. Keeping that boundary saves time and prevents duplicate sends.

10. Frequently asked questions
What is the Monarch receipt email address?
Monarch currently documents receipts@my.monarch.com as its receipt-import address. Send from the email on your Monarch account, a household-member email, or another sender you have verified in Monarch.
Does Monarch require a special subject line?
No. Monarch says no special subject or email format is required. It treats one forwarded email as one receipt, so do not bundle several receipt confirmations into one message and expect them to be separated.
Can Monarch import a receipt that is only in the email body?
Yes. Monarch documents body-only email imports and says it generates a visual image of the email. Expensent handles body-only evidence separately through its optional body-as-proof preference; Monarch's native support does not automatically enable that Expensent setting.
Which receipt files does Monarch accept by email?
Monarch currently documents JPG, PNG, WEBP, HEIC, HEIF, and PDF, with a 10 MB limit per attachment and 30 MB per email. Expensent currently supports PDF, JPG, and PNG attachments.
Why did Monarch not match my receipt?
A common reason is that the transaction is still pending. Monarch currently matches only posted transactions and uses amount, date, and merchant details. It keeps retrying and also provides Find match for manual matching.
Will Monarch change my transaction category?
Not for every receipt. Monarch says a single-category receipt adds a note without replacing the existing category. Multiple extracted categories can update the transaction when Autosplit is enabled.
Can Gmail automatically forward every receipt to Monarch?
Gmail requires the destination to open a verification link before native automatic forwarding can be enabled. Users cannot normally access the Monarch ingestion mailbox, and Monarch has publicly acknowledged this limitation. Manual forwarding and connected-mailbox sending are different paths.
Is Expensent a native Monarch API integration?
Expensent finds current and historical receipt emails and routes recurring patterns to Monarch's documented address. Monarch continues with importing, parsing, matching, splitting, categories, and notifications.
Route receipt emails to Monarch
Expensent finds receipt emails across current and historical mail and routes them from your connected mailbox to Monarch.
