Common wall · My app is not sending email
The app says it sent an email. Nothing arrives.
Why welcome, reset, or receipt emails fail in AI-built apps, what to check without jargon, and when email belongs in a Ship engagement.
Shipping wall
Reviewed July 13, 2026
Direct answer
What this wall usually means.
When an app says it sent email but nothing arrives, the message may never have reached a delivery service, the sender may not be approved, the live app may lack private settings, or the provider may have rejected the recipient. Trace one test message from user action to delivery record before rewriting the email screen.
Recognize it
Symptoms that belong together.
- Password reset reports success, but the inbox stays empty.
- Email works for the founder’s address but not a new customer.
- Messages arrive from a temporary sender or land in spam.
- The preview sends mail while the live app silently does nothing.
First checks
Gather evidence before another patch.
- 01Use a synthetic test account and record the message type, recipient, and exact time.
- 02Check whether the email provider received, rejected, or delivered that specific message.
- 03Confirm the sender address and live domain are approved for real delivery.
- 04Verify that private delivery credentials exist only in the live server-side environment.
DIY or bring in help?
Stop when the risk is larger than the clue.
A focused check is reasonable when you have a stable version and one repeatable failure. Bring in help when the app, customer impact, or safety boundary is no longer clear.
- Account verification or password recovery blocks real users.
- The live app exposes delivery credentials or cannot identify which service sends mail.
- Different message types use conflicting senders, links, or customer data.

Inside the Ship Framework
Connect + Watch
Connect follows each essential message from customer action through the delivery service to its destination. Watch records failures and rejections so the app does not claim success when no message left.

Before you change anything.
Why does email work for me but not for customers?
A provider may allow test delivery only to an approved account, while a live sender still needs domain verification and permission to reach other recipients. Customer addresses can also be rejected or suppressed after previous failures.
Should the app send email directly from the browser?
No private delivery credential should be shipped to a customer’s browser. The browser should request the action, while a protected server-side process sends the message and records the result.
Which emails must work before launch?
Any message required to complete or recover the core journey must be tested. Common examples include account verification, password reset, invitations, receipts, and time-sensitive notifications promised by the product.
