Cannot send mail smtp.gmail.com failed iphone

The frustration of not being able to send emails from your iPhone!

The error "cannot send mail smtp.gmail.com failed" on your iPhone is likely due to one of the following reasons:

  1. Incorrect SMTP settings: Double-check that your SMTP settings are correct. Go to Settings > Mail, Contacts, Calendars > Accounts > [Your Email Account] > Outgoing Mail Server. Make sure the SMTP server is set to smtp.gmail.com and the port is set to 587 (or 465 if you're using SSL/TLS).
  2. Two-factor authentication (2FA) issues: If you have 2FA enabled on your Google account, you may need to generate an App Password to use with your iPhone. Go to your Google Account settings, click on "Security," and then "App passwords." Follow the instructions to generate a new password.
  3. Less secure apps: Google may block sign-in attempts from apps that do not use modern security standards. To allow less secure apps to access your account, go to your Google Account settings, click on "Security," and then toggle "Less secure app access" to "On."
  4. Firewall or network issues: Check your iPhone's firewall settings and ensure that they are not blocking the SMTP connection. Also, try sending an email from a different network or location to rule out any network-related issues.
  5. Account settings: Ensure that your email account is set up correctly on your iPhone. Go to Settings > Mail, Contacts, Calendars > Accounts > [Your Email Account] and check that the account is set up correctly.
  6. SSL/TLS issues: Try setting the SSL/TLS setting to "Off" or "Auto" instead of "On" to see if it resolves the issue.
  7. Outdated iOS or Mail app: Make sure your iPhone is running the latest version of iOS and that your Mail app is up to date.

To troubleshoot the issue, you can try the following steps:

  1. Restart your iPhone and try sending an email again.
  2. Check your email account settings and ensure that they are correct.
  3. Try sending an email from a different email account to rule out any account-specific issues.
  4. Contact your email provider's support team for further assistance.
