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/.
Step 1: Enable "Less Secure Apps" in Gmail
To configure Gmail SMTP, you need to enable access for less secure apps. Below is a step-by-step guide:
Log in to Google Security Go to Google Security and sign in to your Google account.
Sign in to Your Google Account Enter your Google account credentials and sign in.
Scroll down to "Less secure app access" Scroll to the bottom of the page to find the "Less secure app access" option.
Click to Enable App Access Select the option to enable access for less secure apps.
NOTE:
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).
Step 1B: Obtain App Passwords
If you have enabled Two-Factor Authentication (2FA), you will need to generate an App Password:
Go to the App Passwords page.
Choose a name for the App Password and click "Generate."
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.
Step 2: Configure Gmail SMTP in eMailBase
Log in to eMailBase
After obtaining Gmail SMTP information, log in to your eMailBase account.
Go to Sending > Sending Servers
In the management interface, select Sending Servers and click the New Server button.
Choose the Server Type
From the list of server types, choose "SMTP" with the description "Send emails through an SMTP service."
Enter Gmail SMTP Information
Complete the following fields:
Hostname*: smtp.gmail.com
SMTP Username*: Your Gmail email address
SMTP Password*: Use your Gmail account password or the App Password if 2FA is enabled.
SMTP Port*: 465 (SSL) or 587 (TLS)
SMTP Encryption Method: Select SSL or TLS
Save Configuration: After entering all the required information, click Save to complete the SMTP server setup.
Step 3: Additional Setup after SMTP Configuration
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.
Step 4: Verify Sending Identity 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.
Wait for Verification: The system will send a verification email to the address you entered. Open the email and click the activation link to confirm.
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.
Tips for Optimizing Gmail SMTP Email Sending:
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.
