Skip manual forwarding when you can. Expensent connects to Gmail, Outlook, or Google Workspace via OAuth, finds current and historical invoice emails, routes them to your Brex address, and automates recurring sender and subject patterns.
TL;DR
Yes. Brex accepts receipts by email at receipts@brex.com. Brex says an emailed receipt can be part of the email body or an attachment, and receipt uploads can use .pdf, .jpg, .png, or .xml files. Your sending email must be associated with your Brex account or your account copilot.
receipts@brex.com is the standard card-receipt forwarding address. receipts+forwarding@brex.com is the address Brex documents for Gmail and Outlook forwarding rules, with Google Workspace receipt collection running within the next hour. reimbursements@brex.com creates a draft reimbursement request for out-of-pocket expenses not paid with a Brex card.
Where auto-validation is enabled, Brex compares merchant, amount, and purchase date after a receipt is added to an expense. At least 2 of those 3 fields must match for validation. This best-effort validation is separate from the earlier step of matching an emailed receipt to an expense.

Brex Email Paths Explained
Brex documents separate email paths for card receipts, forwarding rules, and reimbursement drafts. Understanding which to use and when helps keep receipts out of manual follow-up.
receipts@brex.com — Standard Receipt Forwarding
Send or forward receipt emails to receipts@brex.com. This is the primary receipt submission email for individual card-receipt forwards.
- •Processing: Brex says receipts can be validated within minutes when enough information matches
- •Best for: Manual forwarding of individual receipt emails
- •Accepts: Emailed receipts in the body or as an attachment; Brex documents .pdf, .jpg, .png, and .xml uploads
- •Validation: Where enabled, Brex checks merchant, amount, and date after attachment
receipts+forwarding@brex.com — Gmail and Outlook Rules
Brex documents receipts+forwarding@brex.com for Gmail and Outlook forwarding rules.
- •Processing: Google Workspace receipt collection sends relevant emails to Brex within the next hour
- •Best for: Email-client forwarding rules or Google Workspace receipt collection
- •Limitation: Depends on email-client or Workspace setup instead of inbox-level review
- •Limitation: Google Workspace receipt collection runs within the next hour, not immediately
reimbursements@brex.com — Out-of-Pocket Expenses
Forward receipts for out-of-pocket purchases (expenses paid with a personal card, not a Brex card) to reimbursements@brex.com. This creates a draft reimbursement request instead of matching to a card transaction.
- •Creates: A draft reimbursement request—not a transaction match
- •Best for: Personal purchases that need company reimbursement (hotel, meals, supplies)
- •Workflow: Draft is created → you review and submit → manager approves → payment is issued
| Feature | receipts@ | receipts+forwarding@ | reimbursements@ |
|---|---|---|---|
| Processing behavior | Can validate within minutes | Within the next hour | Creates draft reimbursement |
| Matches to card transaction | Yes | Yes | No (creates reimbursement) |
| Best use case | Manual forwarding | Gmail or Outlook forwarding rules | Out-of-pocket expenses |
| Forwarding-rule setup needed | N/A | Yes | N/A |
Typo-friendly: Brex also accepts common typos—receipt@brex.com (missing “s”), reciepts@brex.com, and reciept@brex.com all route to the same receipt processing system.
Step-by-Step: How to Forward a Receipt to Brex
Once your email is authorized, here's how to forward a receipt to Brex:
Choose the right email address
Use receipts@brex.com for standard receipt forwarding (most common). Use reimbursements@brex.com only if the expense was paid with a personal card and you need reimbursement. Use receipts+forwarding@brex.com only when setting up Gmail auto-forwarding rules.
Forward the receipt email
Forward the original receipt email to the chosen Brex address. The receipt can be part of the email body or a supported upload file such as .pdf, .jpg, .png, or .xml. To add a memo, include memo: your note here in the email body.
Brex matches, then may validate the receipt
Brex first attempts to match the emailed receipt to an expense. Where auto-validation is enabled, Brex separately compares merchant, amount, and purchase date after the receipt is attached. If sent to receipts@brex.com, validation can happen within minutes. If sent through the receipts+forwarding@brex.compath, expect the forwarding-rule or Workspace collection timing to apply.
Verify in your Brex dashboard
Open the Brex dashboard or mobile app and check that the receipt appears attached to the correct transaction. Brex says emailed receipts are visible only after a successful match. If it is not attached, open the known expense and add the receipt manually. You can also edit the memo, category, or other fields at this point.
File Format and Size Requirements
Brex documents common receipt upload formats, but file requirements can differ by channel and region.
Accepted Formats
- •.pdf — Document files (most common for digital receipts)
- •.jpg / .jpeg — Image files
- •.png — Image files
- •.xml (CFDI) — Mexican fiscal receipt format
- •Email body — Brex says forwarded email receipts can be in the body or an attachment
Limitations
- •Email size — Brex's public receipt support article does not publish a specific email attachment size limit
- •API uploads — Brex developer docs list a 50 MB maximum for the receipt upload endpoint
- •Mexico — Employees in Mexico may need .xml CFDI files to meet local tax requirements
- •Troubleshooting — If upload fails, Brex recommends saving the document as a different file type and trying again
Inline images work: Brex's receipt article says a receipt forwarded to receipts@brex.com can be part of the email body or an attachment. That matters for HTML receipt emails that do not include a separate downloadable file.
Common Issues and Troubleshooting
If your receipts aren't appearing or matching correctly in Brex, work through these checks:
1.Receipt attached but failed validation
Where auto-validation is enabled, Brex requires at least 2 of 3 fields (merchant, amount, purchase date) to match after the receipt is attached. If validation fails, Brex marks the receipt as not verified and may flag the expense for review under your company policy. Review the known expense in Brex; do not treat a validation failure as proof that email delivery or attachment failed.
2.Receipt is older than 2 months
Brex will not auto-match receipts to transactions that are more than 2 months old. Go to your dashboard, find the old expense, and manually attach the receipt. Brex says emailed receipts are visible only after a successful match, so do not rely on a separate unmatched-receipt queue for this fallback.
3.Email not authorized in Brex
Brex says emailed receipts must come from an address associated with your Brex account or your account copilot. If a receipt is not appearing, verify the sender and attach the receipt manually if needed.
4.Gmail forwarding-rule setup not working
Setting up Gmail auto-forwarding to receipts+forwarding@brex.com requires adding the forwarding address in Gmail and completing Gmail's setup flow. If that creates operational friction, use the Brex for Google Workspace add-on where appropriate, or use an OAuth-connected workflow like Expensent instead of a Gmail forwarding rule.
5.Hourly delay with receipts+forwarding@
If you are using receipts+forwarding@brex.com, remember that this address processes receipts in hourly batches. A receipt forwarded through that path may not appear immediately. If you want the standard card-receipt forwarding path, forward directly to receipts@brex.com or use Expensent.
6.Duplicate receipt attached
If you forward the same receipt twice, or forward a receipt for a transaction that already has a virtual receipt auto-generated by Brex, you may end up with duplicate receipts. Check the transaction in your dashboard—if a virtual receipt is already attached, you do not need to forward the email receipt. If you have duplicates, remove the extra one manually.
7.Virtual receipt not auto-generated
Brex says it cannot auto-generate receipts for all merchants; it depends on whether the merchant shares the needed expense details through the card network or an integration. If a virtual receipt was not generated, forward or manually attach the receipt.
Automate Recurring Receipt Emails
Expensent finds current and historical receipt emails, sends documents to receipts@brex.com, and handles recurring sender-and-subject patterns with rules you create.
Connect your email
Link your work email using secure OAuth—we never see your password. Gmail, Outlook, and IMAP supported.
Set receipts@brex.com as your destination
Enter receipts@brex.com as your forwarding address in Expensent. This sends selected or rule-routed messages to Brex's standard card-receipt email path.
Automate repeat patterns
Create a rule from a confirmed receipt email. Future messages with that sender-and-subject pattern route to Brex, while unusual messages remain visible.
What Expensent Adds Before Brex Matching
- Current and historical search : Find receipt and invoice emails already in the inbox, not just messages that arrive after setup.
- Workflow-specific destination — Send selected or rule-routed messages to the Brex destination you verified for that workflow.
- Visible exceptions : Keep unusual or incomplete messages visible without slowing down routine receipt patterns.
- User-owned connection — Individual users can connect a supported mailbox, subject to their provider and organization's admin policy.
- Historical catch-up — Helps review past receipt emails in your inbox so you can forward the ones Brex still needs.
- Paper receipt capture — Built-in phone camera scanner with edge detection. Snap paper receipts and they're forwarded to Brex just like email invoices.
- AI price extraction — Can extract invoice amount, currency, and recipient from supported PDFs and images. International invoices can show both original and converted amounts when exchange-rate data is available.
- Fine-grained control — CC team members on forwarded receipts, attach vendor notes, filter by attachment type, skip $0 invoices, or block specific senders entirely.
- Connected-inbox setup — Connect your mailbox, set the Brex destination, and approve the recurring patterns you want routed

Why is my receipt not matching in Brex?
Check whether the receipt is older than 2 months, the sender address is associated with the Brex account or account copilot, the receipt is present in the email body or an attachment, and the Google Workspace or Gmail forwarding path has run. If Brex does not match it, open the known expense and attach the receipt manually.
What are Brex virtual receipts?
Brex can automatically generate virtual receipts for some transactions, including several common vendors, when the required expense details are available through the card network or an integration. Brex says it cannot auto-generate receipts for all merchants, and a deleted auto-generated receipt cannot be restored by the system.
Can I auto-forward receipts from Gmail to Brex?
Yes. Brex documents receipts+forwarding@brex.com for Gmail forwarding rules and a Google Workspace add-on for labeled receipt emails.

Does Brex accept common typos for the receipt email?
Yes. Brex is forgiving with typos and accepts receipt@brex.com (missing "s"), reciepts@brex.com, and reciept@brex.com in addition to the standard receipts@brex.com. All typo variants route to the same receipt processing system.
