If you have mistakenly reported an email sender as spam in Gmail, there is a way to reverse this action. Go to the spam label in your Gmail inbox, locate the email you previously marked as spam and select it using the checkbox next to it then click on the “not spam” button in the toolbar.

In this comprehensive article, we will guide you through the process of undoing a spam report in Gmail. Moreover, we will present you with three potential solutions in case you continue to encounter the issue of the sender’s emails being redirected to your spam folder, even after marking the initial email as not spam.
How To Unmark an Email In Gmail As Spam
1 – Open your Gmail inbox and navigate to the spam label.
2 -Locate the email that you mistakenly marked as spam and click on the checkbox to the left side of it.
3 – Once the email is selected, find the “not spam” button in the toolbar above the list of emails and click on it.
If you have followed the aforementioned steps, but the emails from the same sender continue to land in your spam folder, here are a few suggestions to resolve the issue:
Solution 1 – Add The Sender To Your Gmail Contacts
To ensure that emails from a specific sender are recognized as legitimate and not marked as spam, you can add them to your Gmail contacts. Here’s how:
1 – Go to contacts.google.com and sign in to your Gmail account.
2 – Click on the “Create contact” button located at the top left of the page.
3 – From the menu that appears, select the “Create a contact” option.
4 – Fill in the sender’s information in the provided form, including their name and email address.
5 – Once you have entered the necessary details, click the “Save” button to add the contact to your Gmail contacts.
Solution 2 – Set Up A Filter To Prevent The Sender’s Emails From Going To Spam

2 – Click on the settings icon located at the top right corner of the page.
3 – In the dropdown menu, select ‘See all settings’.
4 – Navigate to the ‘Filters and Blocked Addresses’ tab.

Solution 3 – Unmark The Sender’s Emails As Spam In Third-Party Email Clients
It is important to note that the individual settings of a third-party email client can override the default behavior of Gmail.
Therefore, if you have marked an email from a particular sender as spam using Outlook, Thunderbird, Pocomail, the Apple Mail app, or the Mail app on your iOS or Android device, and subsequently unmarked that email as spam within the Gmail web app, the sender may still be classified as spam in the third-party email client.
As a result, new emails from that sender in your Gmail inbox may continue to be directed to the spam folder.
To address this issue, it is necessary to unmark the sender as spam within the respective third-party client.
Below, you’ll find a comprehensive guide on how to remove spam classification in several commonly used third-party email clients:
