You can share these instructions with your customers to help ensure they receive your messages and invoices. ### Why Emails Go to Spam Email providers sometimes mistakenly block or send emails to spam folders if they suspect the email is unwanted. Whitelisting tells email providers that emails from a specific address should be delivered to the inbox. Messages and invoices sent from the school or studio will come from **no-reply@app.classmanager.com**. If you have a custom domain, we can set that up to replace the no-reply address—just contact our team for assistance. Customers should check both their inbox and spam folders for emails from this address to ensure they’re receiving your messages. ### Whitelisting Emails: Step-by-Step Instructions Here are the steps for ensuring your emails are whitelisted on major email providers: #### **Gmail Whitelisting** 1. **Mark as Not Spam**: - Go to the spam folder and search for emails from **no-reply@app.classmanager.com**. - Select the emails and click **Not Spam** at the top. 2. **Add to Contacts**: - Click the grid icon in the top-right corner of Gmail, then select **Contacts**. - Click **Add Contact** and enter **no-reply@app.classmanager.com**. Emails from contacts are less likely to go to spam. 3. **Create a Filter**: - Open **Settings** by clicking the cog icon in Gmail and select **Filters & Blocked Addresses**. - Click **Create New Filter**, enter **no-reply@app.classmanager.com** in the "From" field, and select **Create Filter**. Then, tick **Never Send it to Spam**. #### **Yahoo! Mail Whitelisting** 1. **Add to Contacts**: - Click the contacts icon at the top of your inbox. - Scroll down and select **Add a New Contact**, then enter **no-reply@app.classmanager.com**. 2. **Mark as Not Spam**: - Go to the spam folder and search for **no-reply@app.classmanager.com**. - Select the emails and click **Not Spam** at the top. 3. **Create a Filter**: - Click the Settings cog icon and choose **More Settings**. - Select **Filters** and then **Add New Filters**. Enter **no-reply@app.classmanager.com** in the "From" field and choose **Inbox** as the destination folder. #### **Outlook/Hotmail Whitelisting** 1. **Add to Contacts**: - Sign in and click the **People** icon at the bottom-left of the screen (or tap the search icon on mobile). - Select **Create +** and add **no-reply@app.classmanager.com**. 2. **Add as a Safe Sender**: - Go to **Settings** and select **View All Outlook Settings**. - Under **Junk Email**, click **Add** under **Safe Senders and Domains** and enter **no-reply@app.classmanager.com**. Press **Enter** to confirm. --- By following these steps, customers can ensure that messages from your school or studio are delivered directly to their inboxes.
