### [Error: Channel Not Found](https://wpmailsmtp.com/docs/smtpcom-channel-not-found/)

**Note**: This guide applies to the [SMTP.com mailer](https://wpmailsmtp.com/docs/how-to-set-up-the-smtp-com-mailer-in-wp-mail-smtp/ "SMTP.com") in WP Mail SMTP.

## What This Error Means

The **Sender Name** value in WP Mail SMTP doesn’t match any sender configured in the SMTP.com account. SMTP.com uses sender names (also called channels) to associate emails with specific sending settings and IP pools. If the name doesn’t match exactly, SMTP.com rejects the request with a “channel not found” error.

## Common Causes

- The **Sender Name** field in WP Mail SMTP contains a typo or extra whitespace
- You renamed or deleted the sender in the SMTP.com dashboard
- Wrong case (sender names in SMTP.com are case-sensitive)
- The From Email domain in WP Mail SMTP doesn’t match the domain associated with the sender in SMTP.com
- The **Sender Name** field still holds a default or placeholder value instead of the one from SMTP.com

## How to Fix

Here is the complete step-by-step guide to resolving the error.

### Step 1: Copy the Sender Name from SMTP.com

The Sender Name in WP Mail SMTP must match the value SMTP.com stores for that sender exactly, including spelling and capitalization.

Start by logging in to your [SMTP.com](https://my.smtp.com/ "SMTP.com") dashboard. Then, go to the **Senders** page in the main navigation.

![Copy the value from the Name column on the SMTP.com Senders page](https://wpmailsmtp.com/wp-content/uploads/2026/05/copy-sender-name-from-smtpcom.jpg)In the senders table, find the **Name** column. This is the value WP Mail SMTP needs. Copy the exact value from the **Name** column. Spelling and capitalization must match exactly.

**Note**: Sender names are case-sensitive. “MyChannel” and “mychannel” are treated as different names. Always copy and paste rather than typing manually.

If no senders exist in the table, create one in SMTP.com under **Senders** before continuing. Make sure the sender’s domain matches the From Email domain you plan to use in WP Mail SMTP.

### Step 2: Paste the Sender Name in WP Mail SMTP

With the correct value copied from SMTP.com, update the field in WP Mail SMTP.

Start by going to **WP Mail SMTP » Settings** and clicking the **General** tab.

![WP Mail SMTP setting page](https://wpmailsmtp.com/wp-content/uploads/2023/08/wp-mail-smtp-settings.png)Then, scroll to the **Primary Connection** section and confirm **SMTP.com** is selected as the mailer.

![Select SMTP.com mailer](https://wpmailsmtp.com/wp-content/uploads/2024/12/smtp-com-mailer-1536x977.png)Next, find the **Sender Name** field. Or click the **Get Sender Name** link next to the field to open the SMTP.com Senders page directly.

![Click the Get Sender Name link in WP Mail SMTP](https://wpmailsmtp.com/wp-content/uploads/2026/05/get-sender-name-link.png)Clear the **Sender Name** field and paste the value you copied from the **Name** column in SMTP.com.

While here, confirm the **From Email** field uses an address on the same domain that is associated with your sender in SMTP.com. For example, if your sender is configured for `example.com`, the From Email should be something like `wordpress@example.com`.

Finally, click **Save Settings**.

### Step 3: Send a Test Email

Confirm the fix by sending a test email.

To test the fix, go to **WP Mail SMTP » Tools** and click the **Email Test** tab. Enter a recipient email in the **Send To** field, leave the **HTML** toggle ON, and click **Send Email**.

![Test email tab](https://wpmailsmtp.com/wp-content/uploads/2024/10/test-email-tab-1024x1002.png)Once done, look for the success message and confirm the email arrived in your inbox.

## Notes

- The **Name** column on the SMTP.com Senders page is the value that goes into the **Sender Name** field in WP Mail SMTP. These are the same thing: SMTP.com calls it “Name” and WP Mail SMTP calls it “Sender Name.”
- Sender names are case-sensitive. “MyChannel” and “mychannel” are treated as different names. Always copy and paste rather than typing manually.
- If the error persists after updating the Sender Name, verify the sender still exists in SMTP.com with the same name you copied.

That’s It! You now know how to fix the ‘Channel Not Found’ error in SMTP.com and get your emails sending again through WP Mail SMTP.
