How to know your mail have viewed by reciver

Unfortunately, there is no foolproof way to know for certain whether your email has been viewed by the recipient. Email services don't provide a built-in feature to track whether an email has been opened or read. However, there are some indirect methods and tools that can give you an idea:

  1. Read Receipts: Some email services, like Gmail, allow you to request a read receipt from the recipient. This will send a notification to your email when the recipient opens the email. However, this feature is not always available, and recipients can opt-out of receiving read receipts.
  2. Tracking Pixels: Some email marketing tools and services use tracking pixels to track the opening and clicking behavior of recipients. These pixels are tiny images embedded in the email that load when the recipient opens the email. However, this method is not foolproof, as recipients can block or disable tracking pixels.
  3. Email Analytics Tools: There are third-party email analytics tools, like Mailchimp, Constant Contact, or Sanebox, that can provide insights into email engagement, including open rates, click-through rates, and bounce rates. These tools can help you understand how your emails are performing, but they don't provide direct confirmation of whether an email has been viewed.
  4. Social Proof: If you're sending a personal or professional email, you can ask the recipient to confirm receipt or provide feedback on the email. This can be done through a follow-up email or a phone call.
  5. Email Client Features: Some email clients, like Microsoft Outlook, offer features like "Read Receipts" or "Delivery Reports" that can provide information on whether an email has been delivered and read.

Keep in mind that these methods are not foolproof, and recipients may not always respond or provide feedback. The best approach is to focus on crafting high-quality, relevant, and engaging emails that resonate with your audience, rather than relying on tracking or confirmation methods.
