# Troubleshoot common issues

Available in Classic and VPC

You might run into the following problems when using Simple & Easy Notification Service. Find out causes and possible solutions.

## Project creation limit

I didn't create any projects, but the creation limit notification appears.

#### Cause

Simple & Easy Notification Service is available only for business accounts.

#### Solution

To use Simple & Easy Notification Service, convert your personal account to a business account.

To convert to a business account:

1. Log in to the NAVER Cloud Platform console.
2. In the top-right corner, navigate to **My Account** > **Manage account and security** > **Manage account**.
3. Click **[Switch to business account]** in the **Account type** section.
4. When the **Switch to business account** popup appears, check the payment method and click **[Next]**.
5. Agree to the terms of service and click **[Next]**.
6. In the **Document attachment** step, attach your business registration certificate.
  - If your business registration number has changed, submit the "consent form for collection of personal information" additionally.
  - The "consent form for collection of personal information" can be downloaded from **Customer Support** > **Materials**.
7. In the **Business information** step, enter the business information and click **[Next]**.
  - Enter the information to match the information specified in the business registration certificate.
8. In the **Additional information** step, complete real name verification for the person in charge and enter the business address, then click **[Next]**.
  - It is processed within 1–2 business days.
  - In the account conversion process, additional materials may be requested or your request may be rejected.

## Sending limit increase

The message sending limit is too low. I want to increase the sending limit.

#### Cause

A default sending limit is assigned when a project is created, and the service operates only within each sending limit. Request a sending limit increase through Contact Support.

#### Solution

1. In the NAVER Cloud Platform console, navigate to **Menu** > **Customer Support** > **Contact Support**.
2. In the inquiry type, find **Application Services > Simple & Easy Notification Service (SENS)** and select the **service name**.
3. When the Contact Support page appears, fill in the following information to request a sending limit increase.
  - Service ID/Service type
  - Reasons for increasing the limit
  - Base data
  - Services to use (web URL and App Store URL)
  - Estimated usage

              Note

              

For MAIL, if the sending volume is not maintained for a certain period after the limit is increased, the limit may be automatically reduced.

## Image errors in email attachments

Images attached to emails are not displayed.

#### Cause

- If you use an image URL registered in a hosting service, there may be an issue with the image registered in the hosting service.
- If the image is registered in MAIL, it may not be displayed because it has exceeded the personal information retention period. Attached images are stored in accordance with the personal information retention period specified in the terms and conditions, and the data is deleted after the retention period expires.

#### Solution

- If you use an image URL registered in a hosting service, check whether the image URL registered in a hosting service is functioning properly.
- If you attached images directly to MAIL, check when the images were registered.
  - Images that have exceeded the personal information retention period are not displayed as expected. If images are not displayed even within the retention period, contact [Customer Support](https://www.ncloud.com/support/question/service).
  - For stable service operation, it is recommended to use images registered in a separate hosting service.
