[Tips & Tricks](https://knowledgebase.thedealersconcierge.com/knowledge/tips-tricks?hsLang=en) # Using the "+" Sign to Alter Email Addresses for TDC Users You can create a technically unique email address that still redirects to the original email by adding a **"+" sign followed by a value**. This method is supported by most email providers, including Gmail and custom domains like `@mytdc.net`. --- ### **How It Works** If the original email is `christy@mytdc.net`, you can modify it as follows: - `christy+1@mytdc.net` - `christy+sales@mytdc.net` - `christy+manager@mytdc.net` All these variations are treated as unique email addresses by TDC and other systems but will redirect emails to the original email address, `sofya@mytdc.net`. --- ### **Why This Happens** This functionality is based on the email protocol's handling of **address tags**: 1. The **"+" sign** and any value after it are considered **tags**. 2. Email systems **ignore the tag** after the "+" sign when routing the email to the mailbox. 3. This allows you to create variations of your email address without needing to set up a new inbox. --- ### Use Cases in TDC #### Use Case #1: Errors in consumer phone #. Sometimes consumers make errors in entering their phone number while registering on TDC. The system will not allow them to re-register with the same email and a corrected phone number (because it varies from the original). To work around this: 1. Modify the original email address by adding a "+" sign and a tag: - `john.doe+1@example.com` - `john.doe+new@example.com` 2. Register the new account with the altered email and the correct phone number. All TDC communications sent to `john.doe+1@example.com` or `john.doe+new@example.com` will still be delivered to the consumer's original email inbox, `john.doe@example.com`. #### **Example Scenario** 1. **Original Registration**: Consumer registers with `jane.doe@gmail.com` and enters an incorrect phone number. 2. **Account Creation Blocked**: TDC system prevents using `jane.doe@gmail.com` again for a new account with the correct phone number. 3. **Solution**: Consumer uses `jane.doe+1@gmail.com` to create the new account with the updated phone number. 4. **Outcome**: All emails (from both accounts) are delivered to the same inbox, `jane.doe@gmail.com`. --- #### Use Case #2.  Creating second user on TDC Dashboard In some situations, a single user may need to perform multiple roles within TDC, such as working as both a **Salesperson** and a **Sales Manager**. This requires the user to be assigned to transactions under both roles. However, the TDC system does not allow creating multiple accounts with the same email address. #### **Example Scenario** 1. **Create Two User Accounts**: - First account: Assign the **Sales Manager** role to `jane.doe@mytdc.net`. - Second account: Assign the **Sales Person** role to `jane.doe+sales@mytdc.net`. 2. **Role Assignment in Transactions**: - Have the user log into only one account (with the higher access permissions - in this case into Sales Manager\`s account, `jane.doe@mytdc.net`) - No need to log into another account (with lower access permissions) 3. **Email Management**: - The user will be login in as sales manager, and will be able to assign themselves as a sales-person to that transaction as well. - Both email addresses will redirect all communications to the same inbox (`jane.doe@mytdc.net`), allowing the user to manage their roles seamlessly without missing important messages. - [Getting Started](https://knowledgebase.thedealersconcierge.com/knowledge/getting-started?hsLang=en) - [Buyer Portal](https://knowledgebase.thedealersconcierge.com/knowledge/buyer-portal?hsLang=en#main-content) - [Co-Buyer](https://knowledgebase.thedealersconcierge.com/knowledge/buyer-portal?hsLang=en#co-buyer) - [Co-Buyer](https://knowledgebase.thedealersconcierge.com/knowledge/co-buyer?hsLang=en) - [Dealer Dashboard](https://knowledgebase.thedealersconcierge.com/knowledge/dealer-dashboard?hsLang=en#main-content) - [Deal Jacket](https://knowledgebase.thedealersconcierge.com/knowledge/dealer-dashboard?hsLang=en#deal-jacket) - [User Management](https://knowledgebase.thedealersconcierge.com/knowledge/dealer-dashboard?hsLang=en#user-management) - [Compliance Forms](https://knowledgebase.thedealersconcierge.com/knowledge/dealer-dashboard?hsLang=en#compliance-forms) - [Pre- and Post- Purchase Forms](https://knowledgebase.thedealersconcierge.com/knowledge/pre-and-post-purchase-forms?hsLang=en) - [Remote Transactions](https://knowledgebase.thedealersconcierge.com/knowledge/remote-transactions?hsLang=en) - [Ongoing Feature Releases](https://knowledgebase.thedealersconcierge.com/knowledge/ongoing-feature-releases?hsLang=en) - [Tips & Tricks](https://knowledgebase.thedealersconcierge.com/knowledge/tips-tricks?hsLang=en) [![Chill listening crop-3](https://knowledgebase.thedealersconcierge.com/hs-fs/hubfs/TDC%20cropped.png?width=44&height=24&name=TDC%20cropped.png "Chill listening crop-3")](https://thedealersconcierge.com?hsLang=en) thedealersconcierge.com Help Center Copyright © 2026, The Dealer\`s Concierge
