How to disable google security for sending smtp mail

Google's security measures can sometimes block or flag emails sent through their SMTP servers, especially if they contain certain keywords, attachments, or formatting. Here are some steps to help you disable or bypass Google's security measures for sending SMTP mail:

Method 1: Use a different SMTP server

Instead of using Google's SMTP server (smtp.gmail.com or smtp.googlemail.com), you can use a different SMTP server that is not as strict with security measures. Some popular alternatives include:

Method 2: Enable "Less secure apps"

If you're using a Gmail account, you can enable "Less secure apps" to allow non-Google apps to access your account. This will allow you to send emails using Google's SMTP server, but it's not recommended as it may compromise your account security.

To enable "Less secure apps":

  1. Go to your Google Account settings (myaccount.google.com).
  2. Click on "Security" and then "Less secure app settings".
  3. Toggle the switch to "On".

Method 3: Use a third-party SMTP client

Some third-party SMTP clients, such as Mailgun or SendGrid, offer more flexible security settings that can help you bypass Google's security measures. These clients often provide a dedicated SMTP server and API keys that you can use to send emails.

Method 4: Use a custom SMTP server

If you have a custom SMTP server set up, you can configure it to send emails using a different server that is not subject to Google's security measures.

Method 5: Use a Gmail API key

If you're using a Gmail account and need to send emails programmatically, you can use a Gmail API key to authenticate your requests. This will allow you to send emails using Google's SMTP server without triggering security measures.

To use a Gmail API key:

  1. Go to the Google Cloud Console (console.cloud.google.com).
  2. Create a new project or select an existing one.
  3. Enable the Gmail API.
  4. Create credentials for your project (OAuth client ID).
  5. Use the API key to authenticate your requests.

Remember that disabling or bypassing Google's security measures may compromise your account security and may not be recommended. It's always a good idea to review and comply with Google's security policies and guidelines.
