Unfortunately Gmails spam filters are not always 100% accurate and valid emails from services such as 33mail can get mistakenly marked as spam.

A useful feature in GMail is the ability to create filters that prevent misclassification of valid emails.

In this guide, we walk through the process of setting up a filter in Gmail to ensure emails from 33mail are never sent to the spam folder.

Step 1: Open Gmail and Access Settings

1. Open your web browser and log in to your Gmail account.
2. In the top right corner, click on the gear icon to open the settings menu.
3. Select “See all settings” from the dropdown menu.

Step 2: Navigate to the Filters and Blocked Addresses Tab

1. In the Settings menu, click on the “Filters and Blocked Addresses” tab.
2. Scroll down and click on the “Create a new filter” link.

Step 3: Set Up Your Filter Criteria

1. In the filter creation window, you’ll see several fields. Focus on the “From” field.
2. Enter @mailer1@33mail.com in the “From” field. This ensures that any email from this address will be caught by the filter.

Step 4: Choose Your Filter Actions

1. Click on the “Create filter” button at the bottom right of the filter creation window.
2. A new window will appear with various options. To ensure emails from @mailer1@33mail.com are never sent to spam, check the box next to “Never send it to Spam.”
3. You can also choose additional actions, such as marking the email as important or applying a label, but for now, we’ll focus on the spam filter.

Step 5: Finalize and Apply the Filter

1. Once you’ve selected “Never send it to Spam,” click on the “Create filter” button to save your changes.
2. Your filter is now active, and any future emails from @mailer1@33mail.com will bypass the spam folder and go directly to your inbox.
