It’s important to verify email addresses before sending emails for several reasons:Deliverability: Verifying email addresses ensures that the messages you send will reach the intended recipients. Invalid or non-existent email addresses will result in delivery errors and bounce messages, which can damage your sender reputation and deliverability. Check more ways to improve your deliverability. Data quality: Verifying email addresses helps to maintain the quality and integrity of your email list. Invalid or outdated email addresses can lead to inaccurate data and make it more difficult to analyze your sendings. User experience: Verifying email addresses helps to ensure a better user experience for your recipients. When an email is sent to an invalid address, the recipient will not receive the message and may become frustrated, which can lead to a negative perception of your brand. This is especially important for transactional emails. Cost of sending: If you are sending emails to a large number of invalid email addresses, those sendings will still count towards your sending quota, resulting in unnecessarily inflated costs. Good email hygiene can save you money.
