# Sending 100K Emails per Day with Gmail

To send large volumes of emails daily, eMailBase offers a solution that allows you to use your own SMTP, especially when combined with Gmail’s SMTP. With optimal use and adherence to Gmail’s limitations, you can send up to **100K emails per day**.

Below is a detailed guide on configuration and essential tips to optimize your email-sending process.

To get started, you can subscribe to eMailBase’s Private SMTP package here: <https://emailbase.net/own-smtp/>.

*Google has discontinued support for this feature since February 2021 for personal Gmail accounts. This method should only be used for business Gmail accounts (@domain).*

*If you're using a personal Gmail account, you will need to enable App Passwords if you're using two-step verification (2FA).*
{% endhint %}

## <mark style="color:orange;">Step 1B: Obtain App Passwords</mark>

If you have enabled **Two-Factor Authentication (2FA)**, you will need to generate an **App Password**:

1. Go to the [App Passwords](https://myaccount.google.com/apppasswords) page.
2. Choose a name for the App Password and click "Generate."

3. Retrieve the **App Password** and use it instead of your Gmail account password in the SMTP configuration section of eMailBase.

*Google will provide the **App Password** to you only once, so make sure to save it in a secure location.*

## <mark style="color:orange;">**Step 3: Additional Setup after SMTP Configuration**</mark>

### Configure Sending Server Name

* **Name**\*: Assign a name to the SMTP server, e.g., **"SMTP Gmail"**.
* **Default FROM email**: Set the default sender email address.

### Configure Bounce and Feedback Handling

* If you need to monitor bounced emails or feedback, you can configure a **Bounce Handler** and a **Feedback Loop Handler**.

### Sending Speed Limit

* To avoid being blocked or marked as spam by Gmail, set a reasonable email sending speed limit. For example: **200 emails per hour.**

### Managing Sending Identities

* To enhance security and ensure the validity of "From" addresses, you can add and verify domains permitted for sending emails in eMailBase.

After configuring Gmail SMTP, add and verify your sending email address to use it for email marketing campaigns. Steps are as follows:

* **Go to:** Sending > Sending Identity > click "New Sender"
* **Fill in the information:** Enter the "Name" and "Email" you wish to verify.

* **Click "Ok, I got it":** After successfully confirming, return to eMailBase, and you will see a green message stating "Identity verified! This sender is now activated and you can now use it as your FROM address in your campaign".

This completes the sender verification, and you can now use this address in your email campaigns.

## <mark style="color:orange;">**Tips for Optimizing Gmail SMTP Email Sending:**</mark>

* **Add Multiple SMTPs to Avoid Spam**: Use multiple Gmail SMTP accounts and distribute sending across them to reduce the risk of being flagged as spam.
* **Set a Suitable Speed Limit**: Set a lower email-sending limit to avoid Google blocks or spam filtering. For example, limiting to 200-300 emails/hour/account or 1,000 emails/day/account helps keep the system flexible and stable.
