When Email Notifications Fail

Most failed notifications fix themselves: the app automatically retries every failed delivery several times in the background. This guide explains what happens automatically, and what to check when emails still don’t arrive.

CauseDescription
Email provider issueTemporary service outage
Invalid recipientBounced email address
Rate limitingToo many emails sent in a short window
Configuration errorWrong API key or SMTP settings
Spam filterBlocked by the recipient’s filter

You don’t need to click anything — the app handles failures for you:

  1. When a notification fails, it’s retried automatically (several attempts with backoff).
  2. If it still fails after all attempts, the failure is logged for our team.
  3. Your submission data is never lost — it’s always stored in the app, whether or not the email went out.
  1. Go to Settings > Email providers
  2. Open your provider (Resend, SMTP, …)
  3. Use Test and save to send a test email

If the test email fails, the error message tells you what’s wrong (bad API key, connection refused, etc.).

  • Typos in the recipient email (configured in the form editor’s Emails tab) bounce silently.
  • Corporate spam filters are a common culprit — ask your IT to allow-list the provider’s sending domain.

Ask whoever should have received the email to check their spam/junk folder, and mark it as “not spam” to train their filter.

If all notifications suddenly fail at once, check your email provider’s status page for an outage — then wait; queued emails will deliver on retry.

If the test email works but submission notifications don’t arrive:

  1. Verify the form’s recipients in the form editor’s Emails tab.
  2. Contact us from the Feedback page in the app with the form name and the approximate submission time — we can trace the delivery in our logs.
