5 Ways to Fix iPhone Not Sending Emails

Quick Tips

• Start by making switching your default email account. Go to Settings → Mail → Default Account → select the preferred provider.
• If you use iCloud +, temporarily disable Privacy Protection, head to Settings → Mail → Privacy Protection → toggle it off.
• Try removing and adding the email account again. In Settings → Mail → Accounts → select account → Delete Account. Later, tap Add Account from the Accounts section to add it back.

Basic Fixes

• Check your internet connection – Verify that you have an active internet connection on your iPhone. Ensure you have full or at least a couple of network bars to use the mobile data or a fast Wi-Fi connection.
• Enable and disable Airplane mode – To ensure the error doesn’t lie with network connectivity and to remove any glitches, reset the connection by enabling and disabling Airplane mode.
• Keep the Mail app open when sending a large attachment – Gmail and Outlook can send up to 25MB of files over an email. If you are dealing with such large files to send over an email, keep the Mail app open until you hear the sent email sound.
• Check Gmail or Outlook storage—When you run out of email space, you can’t receive/send emails or load images on your iPhone. None of the tricks mentioned in the post will work. So, check your Gmail or Outlook space and empty it if necessary.

Fix 1. Change Default Email Account

The Mail app is perfectly compatible with Gmail, Outlook, Yahoo, and other popular email providers. If you have trouble sending an email with Gmail, move to Outlook, compose, and send the email.

Once comfortable with a specific email provider, you should make it the default account to send emails on your iPhone.

Step 1: Open Settings. Go to the Mail menu.

Step 2: Scroll down, and you will find an option to choose the Default Account.

Step 3: Select your preferred email provider from the following menu.

Fix 2. Disable Privacy Protection in Mail

Privacy Protection is part of iCloud+ and Apple One subscriptions. It is designed to hide your iPhone’s Mail activity. The privacy feature also hides your IP address and loads remote content privately in the background.

The feature might be interfering with the email functions on iPhone. Let’s disable it and try again.

Step 1: Open Settings. Go to the Mail menu.

Step 2: Find Privacy Protection under the Messages menu.

Step 3: Disable the Protect Mail Activity toggle and try sending the email again.

Fix 3. Contact Your Email Provider or System Admin

Are you facing issues sending or receiving emails from a specific email provider? The default Mail app also supports a custom email domain. If you use one of such email providers, contact the company or your company admin to resolve the problem.

You can also reach out to your school IT admin and ask for the latest credentials to send emails from your school email address.

Fix 4. Remove and Add Email Account Again

If you encounter trouble with a specific account on the Mail app, remove it and add it again.

You might have changed your Gmail or Outlook email password. The Mail app on iPhone will ask you to authorize the account again to enable email functions.

Step 1: Launch Settings → Mail menu.

Step 2: Select Account. Tap the email account that troubles you.

Step 3: Select Delete Account and confirm your decision.

Step 4: Go back to the Accounts menu, select Add Account, and choose your email provider to add login details.

Once you add the account, go to the Mail app and start firing up emails to send.
