email_invalid is the Stripe error for an email address that isn’t properly formatted, for example on a Customer or a receipt email. Stripe rejects the whole request, so the customer or payment isn’t created.
**Short answer**
Trim spaces, check the format on your form before calling Stripe, and leave the email field out when there is no email. Show the error next to the email field so the user can fix a typo, then retry.
Rather not fix it yourself? [**Stripe Billing Fix and Setup**](https://app369.com/fixed-price/stripe-billing-setup/) handles it at a fixed price, agreed before work starts.
## **Why Stripe rejects the email, and the fix**
1. 01 ### **The value has spaces or a typo**
> “The email address is invalid (for example, not properly formatted).” [**Stripe, Error codes (email_invalid)**](https://docs.stripe.com/error-codes) A trailing space from autofill or a missing @ fails. Trim the value and check it on the form first.```
const email = form.email.trim();
const customer = await stripe.customers.create({
...(email ? { email } : {}),
name: form.name,
});
```
2. 02 ### **The field holds a name and an address**
> “Check that the email address is properly formatted and only includes allowed characters.” [**Stripe, Error codes (email_invalid)**](https://docs.stripe.com/error-codes) Values like Jane Doe followed by the address in angle brackets, or two addresses separated by a comma, aren’t a single email. Send only the address.
3. 03 ### **The field is blank or only spaces** A form can post a blank email, or spaces only. Spaces fail as a bad format. Trim first, and leave the field out when nothing is left.
4. 04 ### **Imported customers carry bad data** Also check: a CSV import or a sync from another tool can carry old, malformed addresses. Clean the list before the import, and log the row that failed.

Questions
## **More on this error**
**Does Stripe check that the inbox exists? **+
No. email_invalid is about the format. A well-formed address with a typo in the domain passes, so confirm the email in your own sign-up flow if it matters.
**Does Checkout have this problem? **+
Less often. If you don’t pass customer_email, Checkout asks for the email and checks it itself. If you pass one from your own form or database, a badly formatted value can still be rejected, so trim and validate it first.
**Can you fix it for me? **+
If one bug is the whole problem, the App Fix Ticket covers it: a written diagnosis first, then the fix. If the app has more going on, the Launch Check is a written check of the whole app. Each issue found is rated critical, high, medium or low, with where it is and how it was confirmed. No issues worth fixing, no charge. If the Launch Check finds nothing rated medium or higher, Simon refunds the full $450. You keep the report either way. This applies to the first 10 Launch Checks bought after October 30, 2026.
