# Dmail
This mode allows you to interact with the protocol for sending emails via Dmail.
With the functions of this mode, you can send emails to either random or self-specified email addresses. The main advantage of this service is the low transaction fees for interacting with this service.
There are two work options available in this mode: **Full Touch** and **Spam TXs**.
1. **Full Touch** - allows you to send custom emails to custom addresses. You can add addresses manually or generate random ones directly within Combine.
2. **Spam TXs** - allows you to "spam" emails with random content to random email addresses. This mode does not support point farming within Dmail itself but allows you to send multiple transactions through Dmail within one session.

### Setting up and starting a session:
* In the **Mode** section, select **Block Mode**.
* In the **Run mode** section, choose the order in which the wallets will be launched:
1. **Parallel** - parallel operation (multi-threading) with or without proxies.
2. **One-by-one** - wallets will be launched one after another with or without proxies.
3. **One-by-one (mobile proxy)** - wallets will be launched one after another using mobile proxies. Mobile proxies should be added in the **Settings ->** [**Proxies**](https://docs.nfd.gg/main/eng-combine-software/section-settings/proxies) section and linked to accounts in the [**Account Manager**](https://docs.nfd.gg/main/eng-combine-software/account-manager) beforehand.
* To use a ready-made preset of software settings, click on the selection field in the **Select preset** section and choose the required preset.
* To launch a pre-prepared group of wallets, select the necessary group in the **Select Accounts group to launch** section.
* If you want to use the **Spam TXs** mode, just switch to this mode.
* If you want to use the **Full Touch** mode, select it and click **Open custom Dmail settings**:
1. In the **Recipient** section, enter the recipient's email address. Addresses can be entered manually, or you can click **Random recipient email**, and email addresses will be generated randomly for all wallets.
2. In the **Subject** section, enter the subject of the email. By clicking on **Random email subject**, subjects will be generated randomly.
3. In the **Text** section, enter the email text. By clicking on **Random email text**, the email text will be generated automatically.
4. In the **Actions** section, you can update the information for each wallet individually. Click **Update**, and the data in all sections for the specific wallet will be generated automatically.
* Set the delay between the launches of the wallets.
* When you click on **Pro**, the **Gas guard** setting will open. If this delay is activated, your wallet will additionally go to sleep if several accounts in the same session are ready to work simultaneously after reaching the gas level you set for the software. We did this so that all these wallets do not start sending transactions simultaneously after reaching the set gas level. The standard delay is set in the range of 30 to 150 seconds.
* Check the box **Mint and Bind domain if not exists** if you want to mint a random domain for Dmail with 8+ characters for each wallet. It can only be minted once per wallet. The domain is free.
* In the **Max gas price** section, set the maximum gas in the **Linea** network at which transactions will be made. The software will wait for the gas in the **Linea** network to drop to the desired value and only then start making transactions. After the session starts, it is possible to change the upper Gwei level in the **Logs & Progress** tab by going to the **Sessions**subsection.
* If you want the wallets to be activated in random order, leave the **Randomize wallets** checkbox enabled.
* To save the session delay settings for use in other sessions, click the **Save this as preset** button, enter the preset name, and save it. Later, this preset can be selected in the **Select preset** field.
* Click **Update Balances** to get the current ETH balances on the wallets.
* Select the wallets you want to launch and click **Launch**.
* Your wallets are now operationa**l.** You can track the process of wallet operations in the [Logs & Progress](https://docs.nfd.gg/main/eng-combine-software/modules/operation-and-launching-of-modules/linea-module/logs-and-progress) section.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://nfd-gg.gitbook.io/main/eng-combine-software/modules/operation-and-launching-of-modules/linea-module/settings-and-launch/block-mode/dmail.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
