## Why Shaw Email May Not Send Attachments on iPhone or iPad

Before jumping into solutions, it helps to understand why this issue happens in the first place.

Attachments require additional processing when emails are sent. Your device must upload the file, connect securely to the mail server, and verify authentication before the message can be delivered.

If any part of that process fails, attachments may not send properly.

Common causes include:

* Large file sizes exceeding server limits
* Weak or unstable internet connection
* Incorrect SMTP server settings
* Temporary Mail app syncing glitches
* Outdated email password authentication
* Insufficient device storage
* Outdated iOS software
* Spam filters blocking attachments

Identifying the cause helps you fix the issue faster.

## Check Your Internet Connection First

Sending attachments requires a stable internet connection. Large files in particular need more bandwidth to upload successfully.

If your connection drops during the sending process, the email may remain stuck in the Outbox.

### How to test your connection

1. Open **Safari** on your iPhone or iPad.
2. Try loading a website.
3. If the page loads slowly or fails to load, the connection may be unstable.

### Quick fixes to refresh the connection

Try the following:

* Turn **Wi-Fi off and back on**
* Switch between **Wi-Fi and cellular data**
* Restart your **router**
* Enable and disable **Airplane Mode**

Steps to toggle Airplane Mode:

1. Open **Control Center**
2. Turn **Airplane Mode ON**
3. Wait **10 seconds**
4. Turn it **OFF again**

Once your connection stabilizes, try sending the attachment again.

## Check Shaw Mail Service Status

Occasionally the issue may come from the email provider rather than your device.

If Shaw’s mail servers are experiencing temporary outages or maintenance, attachments may fail to send.

### Signs of a server issue

You may notice:

* Emails stuck in the Outbox
* Messages failing to send even without attachments
* Repeated connection errors

If the problem appears suddenly and affects multiple devices, waiting for the service to stabilize is often the best solution.

## Verify Shaw SMTP Settings

Incorrect outgoing mail settings are one of the most common causes of **attachments not sending from iPhone email**.

The SMTP server is responsible for sending messages and attachments.

### How to check SMTP settings

1. Open **Settings**
2. Tap **Mail**
3. Tap **Accounts**
4. Select your **Shaw email account**
5. Tap **SMTP**

### Verify the following settings

* **Server:** mail.shaw.ca
* **Use SSL:** enabled
* **Authentication:** password
* **Server Port:** 587

Incorrect settings can prevent the Mail app from sending attachments properly.

After updating any incorrect information, try sending another email with an attachment.

## Check Incoming IMAP Settings

Although attachments are sent through SMTP, incorrect incoming settings can sometimes disrupt account synchronization.

Confirm these details:

* **Host Name:** mail.shaw.ca

## Reduce Attachment File Size

Large files are one of the most common reasons attachments fail to send.

If your file exceeds that limit, the email may remain stuck in the Outbox.

You can:

* Compress documents into **ZIP files**
* Resize large photos before sending

Smaller files upload faster and are less likely to fail during transmission.

2. Tap **Mail**
3. Tap **Accounts**

Look for messages in:

* **Spam or Junk**

Disabling filters temporarily can help determine if they are interfering with email delivery.
